Description

[Technical field]

[0001] The present invention relates to a cardiac condition display device, a cardiac condition display system, a program and a method. [Background technology]

[0002] After surgical treatment, patients with heart disease, primarily heart failure, undergo cardiac rehabilitation with the help of medical professionals while hospitalized. Cardiac rehabilitation is a type of rehabilitation intended to prevent the recurrence of heart disease and improve quality of life (QOL). Cardiac rehabilitation undertaken during hospitalization is necessary to enable desirable lifestyle behavior after discharge. Exercise therapy is one type of cardiac rehabilitation. It is known that groups that undergo exercise therapy have a higher rate of avoiding cardiac events compared to groups that do not. For this reason, it is important to continue cardiac rehabilitation not only during hospitalization but also after discharge. However, in many cases, patients are unable to continue their desired lifestyle activities after being discharged from hospital. For various reasons, patients with cardiovascular risks are unable to continue cardiac rehabilitation after being discharged from hospital, which can lead to the recurrence of heart disease.

[0003] There is an evaluation support system that enables such patients with cardiovascular risks to visit the hospital at the appropriate time and receive appropriate treatment, and enables medical professionals to accurately grasp the condition of the patient's cardiovascular system (for example, Patent Document 1). The system described in Patent Document 1 is intended to visualize the condition of the patient's cardiovascular system, making it possible to grasp it simply and accurately.

[0032] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. (First embodiment) Overall Configuration of Cardiac Condition Display System 100 FIG. 1 is a diagram showing the overall configuration of a cardiac condition display system 100 according to the first embodiment and a diagram showing functional blocks of a cardiac condition display device 1. As shown in FIG. FIG. 2 is a diagram showing an example of the illustration storage unit 42 of the cardiac condition display device 1 according to the first embodiment. FIG. 3 is a diagram showing an example of the setting level storage unit 44 of the cardiac condition display device 1 according to the first embodiment.

[0033] The cardiac condition display system 100 is a system for encouraging a patient to change his / her behavior so as to continue cardiac rehabilitation by showing the patient's current cardiac condition in an easily understandable manner. 1, the cardiac condition display system 100 includes a cardiac condition display device 1 and an external device 5. The cardiac condition display device 1 is capable of acquiring, for example, biological information (patient biological information) including data related to the cardiac condition of the patient from the external device 5 via wired or wireless communication.

[0034] [Heart condition display device 1] The cardiac condition display device 1 sets multiple levels representing the cardiac condition of the patient based on reference biological information. When new biological information is acquired, the cardiac condition display device 1 assigns a level based on the acquired biological information and outputs an illustration (design) representing the assigned level to the touch panel display 47 (display unit, display device). The cardiac condition display device 1 is preferably a mobile terminal such as a smartphone or a tablet that is possessed and carried by the patient, but may also be other devices such as a notebook computer or a desktop computer.

[0035] The cardiac condition display device 1 shown in FIG. 1 includes a control unit 10, a storage unit 40, a touch panel display 47, and a communication IF (interface) unit 49. The control unit 10 is a central processing unit (CPU) that controls the entire cardiac condition display device 1. The control unit 10 appropriately reads and executes an operating system (OS) and application programs stored in the storage unit 40, thereby cooperating with the above-mentioned hardware and executing various functions.

[0036] Before describing the control unit 10, the storage unit 40 will be described. The storage unit 40 is a storage area such as a semiconductor memory element for storing programs, data, etc. required for the control unit 10 to execute various processes. The storage unit 40 includes a program storage unit 41, an illustration storage unit 42 (design storage unit), a data saving unit 43, a setting level storage unit 44, and a history storage unit 45.

[0037] The program storage unit 41 is a storage area for storing various programs. The program storage unit 41 stores a cardiac condition display application 41a (program). The cardiac condition display application 41a is a program for executing various functions of the control unit 10 described later. The cardiac condition display application 41a can be downloaded and installed, for example, from an application distribution server (not shown). The cardiac condition display application 41a may be configured as one program, or may be configured as separate programs for each functional unit or multiple functional units of the control unit 10 described later.

[0038] The illustration storage unit 42 is a storage area for storing illustrations that visually represent the cardiac condition of a patient for each level. FIG. 2 illustrates an example of a level itemized list 42a stored in the illustration storage unit 42. As shown in FIG. The level item list 42a is a two-dimensional table in which the levels obtained from the biometric information are shown as rows, and the items obtained from the patient's personality information are shown as columns. As an example, the level item list 42a shown in FIG. 2 has six levels from -1 to 5, and eight or more items, but is not limited to this. In addition, the level item list 42a shown in FIG. 2 shows the content of the illustration in words, but the illustration itself may actually be registered, or the illustration may be stored in a separate storage area and its address (location information) may be registered.

[0039] The data storage unit 43 in Fig. 1 is a storage area for storing various data acquired by the cardiac condition display device 1. The data storage unit 43 stores, for example, acquired data such as biological information and personality information in association with the date and time of acquisition. Note that the patient biological information may be acquired by the patient or a medical professional as appropriate, or may be configured to be acquired at the same time according to a system clock or a real-time clock installed in the cardiac condition display device 1. The set level storage unit 44 is a storage area that stores a level setting table (described later) that is set by the level setting unit 13 described later. The history storage unit 45 is a storage area for storing various types of history information based on the processing of the control unit 10.

[0040] Next, the control unit 10 will be described. The control unit 10 includes a pre-processing unit 11 and an information presentation processing unit 21. The pre-processing unit 11 is basically operated while the patient is hospitalized, and performs processing for setting the level of the cardiac condition. The pre-processing unit 11 includes a reference data acquiring unit 12 (reference information acquiring means), a level setting unit 13 (level setting means), and a personality data acquiring unit 14 (personality information acquiring means).

[0041] The reference data acquisition unit 12 acquires the patient's preoperative biological information and acquires biological information at least at any timing from the postoperative period until discharge from the hospital. Here, "preoperative" refers to a state in which the patient has visited or been admitted to a medical institution but has not yet undergone any treatment (open chest surgery, stent surgery, drug therapy, examination such as cardiac catheterization, etc.), and "postoperative" refers to a state after having undergone treatment at a medical institution. Here, the biological information acquired before surgery is considered to be the worst state of the heart where heart failure occurs. However, in reality, it is not always possible to acquire biological information in the worst state of the heart. Therefore, the reference data acquisition unit 12 may acquire multiple pieces of biological information for a certain period before surgery, for example. In addition, it is preferable that the biological information obtained preoperatively is obtained at any timing from after arrival at the hospital or admission to the hospital until receiving treatment, but it may also be obtained at each timing when receiving multiple treatments.

[0042] Next, the biological information acquired at least at any timing from after surgery until discharge from the hospital indicates that the worsened cardiac condition has improved. Here, the biological information acquired at least at any timing from after surgery to discharge from hospital may be acquired at multiple timings, such as after surgery, immediately before discharge from hospital, after exercise therapy during hospitalization, etc. Furthermore, the timing after surgery may be several hours or several days after surgery. The reference data acquiring unit 12 acquires the biological information, for example, by receiving the biological information from an external device 5 described later. Alternatively, the reference data acquiring unit 12 may acquire the biological information by, for example, a patient or the like (including not only the patient but also the patient's family, medical staff, etc.) inputting information using the touch panel display 47.

[0043] The biological information is information that indicates the physical condition of the patient, such as, for example, electrocardiogram, blood pressure, heart rate, blood oxygen concentration, blood iron concentration, weight, blood BNP (Brain Natriuretic Peptide), NT-proBNP amount, uric acid level, creatine kinase amount, respiratory depth, NYHA classification (New York Heart Association functional classification), medical history, echocardiogram, exercise tolerance (AT (Anaerobic Threshol) value (Anaerobic Threshold), peakVO2, VO2max (Maximum Oxygen Uptake), VE / VCO2slope), etc. The biological information to be acquired does not need to be all of the above, but may include data related to the patient's heart condition, such as the abnormal waveform occurrence rate obtained from the electrocardiogram, BNP value, LVEF (left ventricular ejection fraction), LVDs (left ventricular end systolic diameter), E / A, E / e' (diastolic function), etc., that can be read from echocardiogram image data. The data relating to the patient's cardiac condition may be data obtained from the patient himself / herself, as described above, or it may be data relating to the cardiac condition predicted by AI based on the patient's own data. It is also known that a certain level of activity can maintain cardiac health, and therefore the biological information may include the amount of activity, such as the number of steps.

[0044] The level setting unit 13 sets a plurality of levels representing the cardiac condition of the patient based on the plurality of pieces of biological information acquired by the reference data acquiring unit 12. For example, the plurality of levels set by the level setting unit 13 may be A1 for the cardiac condition obtained from the preoperative biological information and A0 for the cardiac condition obtained from the postoperative biological information. Here, the level setting unit 13 may adopt the worst cardiac condition from among the multiple pieces of acquired biological information as the cardiac condition obtained from the preoperative biological information designated as A1, or may adopt the average value of the multiple pieces of acquired biological information as the biological information. In addition, the level setting unit 13 may adopt the cardiac condition obtained from the postoperative vital signs to be A0 at the very first timing after surgery, or may adopt the best cardiac condition from among the multiple vital signs obtained.

[0045] For example, when biological information is acquired after surgery and immediately before discharge, the multiple levels set by the level setting unit 13 may be, for example, A1 for the cardiac condition obtained from the biological information before surgery, A0 for the cardiac condition obtained from the biological information after surgery, and A0-2 (best mode) for the cardiac condition obtained from the biological information immediately before discharge. Note that, depending on the patient, the cardiac condition may not improve sufficiently during hospitalization and may gradually recover over several months after discharge, so the postoperative cardiac condition A0 may be updated to A0-3 for the cardiac condition obtained from the biological information several months after discharge. The cardiac condition of a patient who does not undergo cardiac rehabilitation after discharge may deteriorate from the preoperative cardiac condition A1, and the patient may be re-admitted. In this case, the preoperative cardiac condition A1 may be replaced with the cardiac condition A1-2 at the time of re-admission.

[0046] The level setting unit 13 sets multiple levels using the cardiac conditions A0 and A1 according to thresholds indicated in, for example, guidelines, etc. Guidelines created by academic societies, such as the "Guidelines for the Treatment of Acute and Chronic Heart Failure (Revised Edition 2017)," can be used as guidelines. However, multiple levels may be set according to a patient's own thresholds without following the guidelines, etc. For example, when blood BNP is used as biological information and the A0 value is 30 pg / mL and the A1 value is 400 pg / mL, the levels may be determined as shown in a level setting table 44a shown in FIG. 3(A). In addition, level-1 (severe) shown in the level setting table 44a may be set in advance using cardiac conditions A0 and A1, or may be reset using a cardiac condition such as A1-2 obtained when the patient is re-admitted to hospital.

[0047] In addition, an electrocardiogram may be used as biological information, and the occurrence rate of abnormal waveforms obtained from the electrocardiogram (=abnormal electrocardiogram waveforms / total electrocardiogram waveforms×100%) may be used to classify the levels as shown in level setting table 44b in FIG. 3(B) when, for example, the A0 value is 0.2% and the A1 value is 30%. In this embodiment, the levels are set so that when the cardiac condition is improving in the level setting tables 44a and 44b (i.e., when the levels are low in the level setting tables 44a and 44b), the numerical intervals are small, and when the cardiac condition is worsening in the level setting tables 44a and 44b (i.e., when the levels are high in the level setting tables 44a and 44b), the numerical intervals are large. This can reduce the chance that a patient in a healthier condition will overlook a sign of deterioration. However, the numerical intervals may be set to be equal instead of following this. The items used for classifying the levels are not limited to the abnormal waveform occurrence rate, but may be, for example, the following items. -LVEF (left ventricular ejection fraction), left ventricular end-systolic diameter (LVDs), and diastolic function (E / A, E / e') obtained by echocardiography - NYHA classification determined based on the patient's subjective symptoms during physical activity Additionally, blood pressure and other information (uric acid level, weight, and physical findings of the patient) may also be used as a reference.

[0048] The level setting unit 13 may use multiple types of data as the biological information. The level setting unit 13 may use multiple common types of data measured previously, or may use only data of one type of item. The level setting section 13 may set the levels as follows, for example. (1) Preoperative LVEF value, NYHA classification, weight, blood pressure, and BNP value are recorded and classified as A1. (2) Postoperative LVEF value, NYHA classification, and blood pressure are recorded and classified as A0. (3) Levels are determined based on LVEF and NYHA classification. Then, the level setting unit 13 stores the level setting table with the levels divided in the set level storage unit 44.

[0049] The personality data acquisition unit 14 acquires personality information of the patient. The personality data acquisition unit 14 includes at least one of information regarding personality obtained through psychological diagnosis such as big5, PHQ-9, HADS-A, and the patient's hobbies and preferences (usual diet (salt concentration, water content), drinking and smoking, exercise experience), etc. For example, according to the big5, a person's personality can be classified according to five factors. For example, about 15 simple questions are asked, and the patient is asked to select answers to the questions, which are then used to express the five factors as a score. The five factors are, for example, extroversion (sociable, active personality, assertiveness, proactiveness, excitement-seeking), emotional stability (emotional stability, resistance to anxiety, stress tolerance, easygoing), openness (curiosity, intelligence, interest in new information, artistic ability, adventurous spirit), conscientiousness (hardworking, responsible, trustworthy personality, honesty, keeping promises), and agreeableness (cooperative, cooperative, sympathetic, compassionate, caring, kindness). It can be determined that the higher the score, the more likely a person is to have a tendency toward that factor. The method of acquiring information about personality by big5 described above is just an example. The personality data acquiring unit 14 may acquire information about personality from, for example, a diagnosis provided by an external service that performs personality judgment.

[0050] The information presentation processing unit 21 performs processing to set a plurality of levels representing the cardiac condition of the patient, acquire biometric information of the patient, assign a level based on the acquired biometric information, and display a manner indicating the level. The information presentation processing unit 21 includes a target data acquisition unit 22 (additional biometric information acquisition means), a level assignment unit 23 (level assignment means), an item selection unit 24 (item selection means), a status confirmation unit 25 (status confirmation means), a status output unit 26 (status output means), and a notification output unit 27 (notification output means).

[0051] The target data acquiring unit 22 newly acquires biological information of the patient after the level setting unit 13 sets the level. The target data acquiring unit 22 newly acquires biological information of the patient after the patient is discharged from the hospital, for example. The newly acquired patient biological information may be acquired from the post-surgery period until the patient is discharged from the hospital after the multiple levels are set. Here, the biological information acquired by the target data acquiring unit 22 may be, for example, an electrocardiogram or the like measured by a measuring device 5a (described later) carried by the patient, or may be information measured at a medical institution when the patient visits the medical institution. The level assignment unit 23 assigns a level based on the biological information acquired by the target data acquisition unit 22 from a level setting table stored in a set level storage unit 44 .

[0052] The item selection unit 24 uses the personality information acquired by the personality data acquisition unit 14 to select an item from the illustration storage unit 42. For example, when information indicating a preference for alcohol is acquired as personality information, the item selection unit 24 selects an item of illustrations relating to alcohol. Also, for example, if the personality information obtained from the above-mentioned big 5 is low extraversion (1 point), medium conscientiousness (3 points), high emotional stability (6 points), low openness (0 point), and medium agreeableness (3 points), the item selection unit 24 will select, for example, an illustration of a dog as an illustration that is familiar and comforting, since the emotional stability is high and the extraversion and openness are low. When the patient's most recent level is stored in the history storage unit 45, the condition checking unit 25 checks the tendency of the cardiac condition from the patient's most recent level and the new level assigned by the level assigning unit 23.

[0053] When the patient's most recent level is not stored in the history storage unit 45, the status output unit 26 acquires an illustration corresponding to the item selected by the item selection unit 24 and the level assigned by the level assignment unit 23 from the illustration storage unit 42, and outputs the acquired illustration as a display mode to the touch panel display 47. When the status confirmation unit 25 confirms that the cardiac condition has improved or remained the same, the status output unit 26 outputs an illustration of the item selected by the item selection unit 24 and the new level assigned by the level assignment unit 23 to the touch panel display 47. When the status confirmation unit 25 confirms that the cardiac condition has remained the same, the new level assigned by the level assignment unit 23 remains unchanged. Therefore, the illustration of the new level assigned by the level assignment unit 23 and the illustration displayed before the update are the same. As a result, the illustration output to the touch panel display 47 does not change from the one displayed before the update. In the above, when the condition confirmation unit 25 confirms that the cardiac condition has improved or is remaining the same, the patient may be configured to be able to select an illustration of a desired item as a reward. Furthermore, when a predetermined time (e.g., 5 days) has elapsed after the notification output unit 27 outputs the notification, the status output unit 26 outputs to the touch panel display 47 an illustration corresponding to the item selected by the item selection unit 24 and the new level assigned by the level assignment unit 23.

[0054] When the condition checking section 25 checks that the cardiac condition has worsened, the notification output section 27 outputs to the touch panel display 47 a notification indicating that the cardiac condition has worsened. In this embodiment, the notification output unit 27 is configured to issue a notification when the condition checking unit 25 checks that the cardiac condition has worsened, but a notification output unit 27-2 (not shown) may be provided in addition to the notification output unit 27. When the condition checking unit 25 checks that the patient's cardiac condition remains poor, the notification output unit 27-2 may output a notification encouraging the patient to visit a hospital to the touch panel display 47 in response to, for example, the fact that the patient's cardiac condition has remained at level 1 for a predetermined period of time (e.g., 5 days) having passed.

[0055] The touch panel display 47 functions both as an input section that accepts touch operations by the finger of a patient who is the user of the cardiac condition display device 1, and as a display section. The communication IF unit 49 is an interface for communicating with, for example, the external device 5 via a communication network or the like as necessary.

[0056] It should be noted that a computer refers to an information processing device equipped with a control unit, a storage device, etc., and the cardiac condition display device 1 is an information processing device equipped with a control unit, a storage device, etc., and is included in the concept of a computer. Furthermore, the cardiac condition display device 1 is not limited to a smartphone, a tablet, etc., but may be a personal computer (PC), etc. In that case, instead of the touch panel display 47, it may be equipped with an input device such as a keyboard and a mouse, and a display device such as an LCD (Liquid Crystal Display).

[0057] [External device 5] 1 is a device that transmits biological information to the cardiac condition display device 1. The external device 5 includes, for example, a measuring device 5a, a server 5b, a PC 5c, etc., and includes at least a control unit, a storage unit, an input / output unit, and a communication IF unit, although not shown. The measuring device 5a is, for example, a wearable device that measures biological information of a patient. In addition to a wearable device, the measuring device 5a may be, for example, a device installed in a medical facility such as an X-ray device, or a portable cardiac echo device or weight scale. The measuring device 5a further includes a sensor unit that measures the patient's electrocardiogram, blood pressure, etc., and the control unit transmits the measured biological information to the cardiac condition display device 1 via the communication IF unit. The server 5b is, for example, a device provided in a medical institution, and manages biological information of patients. The PC 5c is a device that is owned by, for example, a medical institution or a patient, and that manages biological information of the patient. For example, the server 5b and the PC 5c transmit the patient's biological information to the cardiac condition display device 1 in response to a request from the cardiac condition display device 1.

[0058] [Processing Description] Next, the processing in the cardiac condition display device 1 will be described. First, the pre-treatment performed while the patient is hospitalized will be described. FIG. 4 is a flowchart showing the reference creation process of the cardiac condition display device 1 according to the first embodiment. As a premise, a cardiac condition display application 41a is installed in the patient's cardiac condition display device 1. Then, for example, in a medical institution, a device (not shown) for acquiring various types of biological information acquires the biological information of a patient before surgery, and transmits the acquired biological information via, for example, the server 5b to the cardiac condition display device 1. Here, the device for acquiring biological information includes various devices such as a device for acquiring an electrocardiogram and a device for acquiring an echocardiogram.

[0059] In the cardiac condition display device 1, by performing an operation to acquire reference data from a menu screen (not shown), in step S (hereinafter, "step S" will be simply referred to as "S") 11 in FIG. 4, the control unit 10 (reference data acquisition unit 12) of the cardiac condition display device 1 acquires preoperative biological information and stores the acquired biological information in the data storage unit 43. Then, the control unit 10 stores the processing history in the history storage unit 45. Note that the control unit 10 stores the processing history in the history storage unit 45 each time, but a description thereof will be omitted hereinafter. In S12, the control unit 10 sets the cardiac condition indicated by the preoperative biological information to A1. In S13, the control unit 10 (reference data acquisition unit 12) acquires postoperative biological information and stores the acquired biological information in the data storage unit 43. Here, as a method for the control unit 10 to acquire postoperative biological information, a device for acquiring biological information similar to that for preoperative biological information may be used.

[0060] In S14, the control unit 10 sets the cardiac state indicated by the postoperative biological information to A0. In S15, the control unit 10 defines A0 as an improved cardiac condition and A1 as a recurrent heart failure condition, regarding the cardiac condition of the patient. In S16, the control unit 10 (level setting unit 13) sets a plurality of levels using the cardiac conditions A0 and A1 of the patient. In S17, the control unit 10 (level setting unit 13) stores a level setting table including the set levels in the set level storage unit 44, and ends this process.

[0061] In the above example, the level is set based on the patient's pre- and post-operative biometric information. However, in addition to the post-operative biometric information, the biometric information before discharge may also be acquired and the level may be set based on the acquired biometric information. Generally, cardiac rehabilitation is actively performed during hospitalization, so the cardiac condition is considered to be better immediately before discharge than after surgery. Therefore, when the control unit 10 (reference data acquisition unit 12) acquires biometric information immediately before discharge, the control unit 10 may set (update) the cardiac condition to A0 and perform the process from S15 onwards again, or may set A0-2 (best mode). In addition, although the example has been described in which bio-information is acquired using a device at a medical institution for acquiring bio-information, and the cardiac condition display device 1 acquires the bio-information from the device for acquiring bio-information via the server 5b, the cardiac condition display device 1 may also acquire the bio-information directly from, for example, a measuring device 5a.

[0062] Next, an information presentation process that is mainly performed periodically by a patient after being discharged from a hospital will be described. 5 and 6 are flowcharts showing the information presentation process of the cardiac condition display device 1 according to the first embodiment. FIG. 7 is a diagram showing an example of a display screen of the cardiac condition display device 1 according to the first embodiment. FIG. 8 is a diagram showing another example of an illustration displayed on the cardiac condition display device 1 according to the first embodiment.

[0063] In S31 of FIG. 5, the control unit 10 (target data acquisition unit 22) of the cardiac condition display device 1 acquires new biological information, and causes the data storage unit 43 to store the acquired biological information. In S32, the control unit 10 (level assignment unit 23) assigns a level based on the acquired biological information from the level setting table stored in the set level storage unit 44.

[0064] In S33, the control unit 10 judges whether or not to accept the personality information. When the patient performs an operation for registering personality information from a menu screen (not shown), for example, the control unit 10 judges that the personality information is accepted. If the personality information is accepted (S33: YES), the control unit 10 shifts the process to S34. On the other hand, if the personality information is not accepted (S33: NO), the control unit 10 shifts the process to S35. In S34, the control unit 10 (personality data acquisition unit 14) acquires personality information, and stores the personality information in the data storage unit 43. Thereafter, the control unit 10 shifts the process to S36.

[0065] On the other hand, in S35, the control unit 10 judges whether or not personality information has been registered. The control unit 10, for example, refers to the data storage unit 43 to judge whether or not personality information has been registered. If the patient has performed the task of registering personality information at least once, the judgment is YES. If personality information has been registered (S35: YES), the control unit 10 transfers the process to S36. On the other hand, if personality information has not been registered (S35: NO), the control unit 10 transfers the process to S37.

[0066] In S36, the control unit 10 (item selection unit 24) uses the personality information to select a corresponding item from the illustration storage unit 42. Thereafter, the control unit 10 shifts the process to S41 in FIG. On the other hand, in S37, the control unit 10 selects a predetermined illustration item from the illustration storage unit 42. When performing this process, since the patient's personality information is not registered, for example, a general illustration of a heart may be selected. After that, the control unit 10 moves the process to S41 in FIG. 6.

[0067] In S41 of Fig. 6, the control unit 10 (state confirmation unit 25) determines whether or not the most recent level has been registered. The control unit 10 determines whether or not the most recent level has been registered, for example, by referring to the history storage unit 45. If the most recent level has been registered (S41: YES), the control unit 10 shifts the process to S42. On the other hand, if the most recent level has not been registered (S41: NO), the control unit 10 shifts the process to S45. In S42, the control unit 10 (condition confirmation unit 25) confirms the tendency of the cardiac condition from the most recent level of the patient and the new level assigned in the process of S32 in FIG.

[0068] In S43, the control unit 10 (state confirmation unit 25) judges whether the state has worsened. If the state has worsened (S43: YES), the control unit 10 shifts the process to S44. On the other hand, if the state has not worsened (S43: NO), the control unit 10 shifts the process to S45.

[0069] In S44, the control unit 10 (notification output unit 27) outputs a notification to the touch panel display 47 indicating that the cardiac condition is worsening. If the cardiac condition is worsening and the image is changed to an illustration of the worsening condition, this can be quite damaging to the patient. For this reason, the notification is first issued to inform the patient of the worsening cardiac condition. Showing the notification to the patient can be an opportunity to hasten cardiac rehabilitation. Thereafter, the control unit 10 ends this process. When a predetermined time has elapsed since the notification was output, the control unit 10 (status output unit 26) outputs an illustration corresponding to the new level to the touch panel display 47. When the information presentation process is performed again before the predetermined time has elapsed since the notification was output, the illustration to be output when the predetermined time has elapsed since the notification was output may not be output, and an illustration based on the process performed again may be output.

[0070] On the other hand, in S45, the control unit 10 (status output unit 26) outputs, among the illustrations of the items selected in the process of S36 or S37 in Fig. 5, an illustration corresponding to the new level assigned in the process of S32 in Fig. 5 to the touch panel display 47. Thereafter, the control unit 10 ends this process.

[0071] Here, a specific example of a display screen including an illustration output to touch panel display 47 will be described. FIG. 7 shows a display screen for each cardiac condition when the illustration is a heart. FIG. 7(A) is an example of a screen 61 when the level is "1", FIG. 7(B) is an example of a screen 62 when the level is "3", and FIG. 7(C) is an example of a screen 63 when the level is "4".

[0072] The screen 61 in FIG. 7(A) includes an illustration area 61a, a comment area 61b, a rehabilitation date area 61c, and a biometric value area 61d. The illustration area 61a is an area for outputting an illustration corresponding to a level and which is an illustration stored in the illustration storage unit 42. In the illustration area 61a of Fig. 7(A), an illustration of a dark-colored heart is displayed. The comment area 61b is an area for outputting a comment corresponding to the level. For example, the comment corresponding to the level may be a comment registered in the storage unit 40 in advance. The rehabilitation date area 61c is an area for outputting the number of days that have passed since the day of rehabilitation. When a patient undergoes rehabilitation, the patient can register the fact that he or she has undergone rehabilitation using a registration function (not shown), and the number of days is counted and output. The biometric value area 61d is an area for outputting the biometric information value when the illustration is decided.

[0073] The screen 62 in FIG. 7(B) and the screen 63 in FIG. 7(C) also have similar screen areas. An illustration of a heart in a slightly brighter color is output in an illustration area 62a of the screen 62, and an illustration of a heart in a brighter color is output in an illustration area 63a of the screen 63, and a glow is drawn. In this way, by showing the improvement of the heart condition from screen 61 to screen 63 by the heart illustrations displayed in illustration areas 61a to 63a, the patient can intuitively understand the heart condition. Here, the illustrations output in the illustration area can be different, taking into account the patient's preferences, etc.

[0074] FIG. 8 shows an example of a heart illustration representing the cardiac state, which is different from that shown in FIG. Fig. 8(A) shows what is displayed in illustration areas 71a to 73a on screens corresponding to screens 61 to 63 shown in Fig. 7. Illustration area 71a is displayed in dark colors, and an illustration of a heavily cracked heart is output. Illustration area 72a is displayed in slightly lighter colors, and an illustration of a heart that is slightly cracked is output. Illustration area 73a is displayed in lighter colors, and an illustration of a heart with no cracks is output.

[0075] 8B shows an illustration of a heart character. An illustration area 81a shows an illustration of a tired and collapsed heart character. An illustration area 82a shows an illustration of a standing heart character, and an illustration area 83a shows an illustration of a lively heart character jumping up.

[0076] Fig. 8(C) is an illustration of a dog character. Fig. 8(C) is output, for example, for a patient who has been determined to like dogs based on personality information. In the illustration area 91a, an illustration of a dog character that is exhausted and collapsed is output. In the illustration area 92a, an illustration of a dog character in a sitting position is output, and in the illustration area 83a, an illustration of a lively dog ​​character that has stood up is output. If the personality information is not registered, the control unit 10 may output an illustration corresponding to a predetermined item among the items stored in the illustration storage unit 42.

[0077] As described above, the cardiac condition display device 1 according to the first embodiment has the following advantages. In the first embodiment, a patient's biological information including data related to the patient's cardiac condition is acquired at multiple timings, multiple levels representing the patient's cardiac condition are set based on the acquired multiple pieces of biological information, new biological information is acquired, a level based on the acquired biological information is assigned from the multiple set levels, and a display form representing the assigned level is output to the touch panel display 47. One piece of biological information acquired at multiple timings is acquired before the patient's surgery, and the other piece of biological information is acquired at least at any timing from the patient's post-surgery until discharge from the hospital.

[0078] This allows multiple levels representing the cardiac condition to be set using the biometric information of a hospitalized patient in the worst state before surgery and the biometric information of a better state at least at any timing between after surgery and discharge from the hospital. Then, a level based on the newly acquired biometric information can be assigned, and a display mode representing the assigned level can be displayed. Therefore, the patient can check his or her own cardiac condition at the time of newly acquiring the biometric condition as a level in the display mode. As a result, the patient will strive to maintain or improve the level, which may be an opportunity for the patient to actively engage in cardiac rehabilitation, and the patient's behavioral change can be promoted.

[0079] In the first embodiment, an illustration corresponding to a level is obtained from the illustration storage unit 42 that stores illustrations that visually represent the cardiac state for each of a plurality of levels, and the illustration is output as a display form. This allows the patient to grasp his / her own cardiac condition at the time when the biological condition is newly acquired as an illustration, so that the cardiac condition can be provided to the patient in an intuitive and easy-to-understand manner.

[0080] In the first embodiment, the illustration storage unit 42 stores a plurality of different types of illustrations visually expressing the heart condition in association with each of a plurality of levels for each item indicating the type of illustration, and when personality information, which is data related to the personality of the patient, is acquired, an item in the illustration storage unit 42 is selected based on the acquired personality information. Then, an illustration corresponding to the selected item and the level is output as a display form. This allows patients to understand their own cardiac condition at the time of acquiring their new biological status using illustrations that match their personality and preferences, and can influence the patient's emotional experience to encourage behavioral change.

[0081] In addition, in the first embodiment, when further biometric information is acquired, a new level based on the acquired new biometric information is assigned from a plurality of levels, and the trend of the cardiac condition is confirmed based on the most recent level stored in the history memory unit 45 and the new assigned level. If a deterioration in the cardiac condition is confirmed, a notification indicating that the cardiac condition is worsening is output to the touch panel display 47. This makes it possible to directly inform the patient of the worsening cardiac condition by issuing a notification if the cardiac condition has worsened since the previous time.

[0082] In the first embodiment, a display mode showing the new assigned level is output to the touch panel display 47 after a predetermined time has elapsed since the notification was output. This allows the system to prompt the patient to change their behavior and give them some time to think about their heart condition if the condition worsens, rather than immediately displaying the condition.

[0083] Furthermore, in the first embodiment, when it is confirmed that the cardiac condition has improved or remained the same, a display mode indicating the newly assigned level is output to the touch panel display 47. This allows the display to reflect when the heart condition has improved or is maintained at the current level, thereby further motivating the patient to change their behavior.

[0084] Second embodiment In the second embodiment, a device that acquires life information of a patient and displays a cardiac condition using the acquired life information will be described. In the following description, parts that perform the same functions as those in the first embodiment described above will be denoted by the same reference numerals or with the same reference numerals at the end, and duplicated descriptions will be omitted as appropriate. [Overall Configuration of Cardiac Condition Display System 200] FIG. 9 is a diagram showing the overall configuration of a cardiac condition display system 200 according to the second embodiment and a diagram showing functional blocks of a cardiac condition display device 201. As shown in FIG. FIG. 10 is a diagram showing an example of the influence degree storage unit 246 of the cardiac condition display device 201 according to the second embodiment. The cardiac condition display system 200 shown in FIG.

[0085] [Heart condition display device 201] The cardiac condition display device 201 shown in FIG. 9 includes a control unit 210, a storage unit 240, a touch panel display 47, and a communication IF unit 49. The control unit 210 includes a pre-processing unit 211 and an information presentation processing unit 221 . The pre-processing unit 211 includes a reference data acquiring unit 12, a level setting unit 13, and a life data acquiring unit 215 (life information acquiring means). The life data acquisition unit 215 acquires life information of the patient, such as family structure, occupation, level of care required, medication, usual amount of exercise, sleep time, etc., and includes at least one of these. For example, the life data acquiring section 215 may prepare a questionnaire regarding lifestyle habits and the like in advance, have the patient answer it, and accept the answers as the life information.

[0086] The information presentation processing unit 221 includes a target data acquisition unit 22, a level assignment unit 23, a status confirmation unit 25, a status output unit 226 (status output means), a notification output unit 27, an impact calculation unit 228 (impact calculation means), and a future level assignment unit 229 (future level assignment means).

[0087] When the patient's most recent level is not stored in the history storage unit 45, the status output unit 226 acquires a predetermined illustration corresponding to the level assigned by the level assignment unit 23 from the illustration storage unit 42, and outputs the acquired predetermined illustration as a display mode to the touch panel display 47. When the status confirmation unit 25 confirms that the cardiac condition has improved or remained the same, the status output unit 226 outputs a predetermined illustration of a new level assigned by the level assignment unit 23 to the touch panel display 47. Furthermore, the status output unit 226 outputs a predetermined illustration corresponding to the new level assigned by the level assignment unit 23 to the touch panel display 47 in response to the lapse of a predetermined time after the notification output unit 27 outputs a notification. Furthermore, the status output unit 226 outputs a predetermined illustration corresponding to the future level assigned by the future level assignment unit 229 to the touch panel display 47.

[0088] The influence degree calculation section 228 refers to the influence degree storage section 246 and calculates the patient influence degree based on the life information acquired by the life data acquisition section 215. The future level assignment unit 229 assigns a future level corresponding to a future patient from among a plurality of levels, taking into account the patient impact calculated by the impact calculation unit 228 and the biological information acquired by the target data acquisition unit 22.

[0089] The storage unit 240 includes a program storage unit 241 , an illustration storage unit 42 , a data saving unit 43 , a setting level storage unit 44 , a history storage unit 45 , and an influence storage unit 246 . A cardiac condition display application 241a is stored in the program storage unit 241. The cardiac condition display application 241a is a program for executing various functions of the control unit 210. The impact level storage unit 246 is a storage area for storing the impact level on heart disease related to lifestyle information. FIG. 10 illustrates a sleep influence degree table 246a showing the degree of influence on heart disease regarding sleep time. This sleep influence table 246a is a correction coefficient calculated by the sleep duration and the cardiac disease mortality risk based on the patient demographic characteristic data. Various tables based on each data may be stored in the influence storage unit 246. This table is merely an example, and does not necessarily have to be applied to all patients. The correction coefficients and the thresholds of cardiac mortality risk do not necessarily have to be set in this manner.

[0090] [Processing Description] Next, the processing in the cardiac condition display device 201 will be described. The criteria creation process performed while the patient is hospitalized is the same as in the first embodiment (FIG. 4). Next, an information presentation process that is mainly performed periodically by a patient after being discharged from a hospital will be described. 11 and 12 are flowcharts showing the information presentation process of the cardiac condition display device 201 according to the second embodiment. The processes of S231 and S232 in FIG. 11 are similar to the processes of S31 and S32 in the first embodiment (FIG. 5).

[0091] In S233, the control unit 210 judges whether or not to accept the life information. For example, the patient performs an operation for registering the life information from a menu screen (not shown), and the control unit 210 judges that the life information is accepted. If the life information is accepted (S233: YES), the control unit 210 shifts the process to S234. On the other hand, if the life information is not accepted (S233: NO), the control unit 210 shifts the process to S241 in FIG. 12. In S234, control unit 210 (life data acquisition unit 215) acquires the life information, and stores the personality information in data storage unit 43. In S235, the control unit 210 sets the living situation indicated by the acquired living information to B0.

[0092] In S236, the control unit 210 (impact degree calculation unit 228) calculates the patient influence degree from the living condition of the patient B0 and the influence degree related to the living habits. Using the sleep influence degree table 246a illustrated in Fig. 10, if the living condition of the patient B0 is a sleeping time of less than 6 hours, the control unit 210 determines the patient influence degree to be "Level -1". In S237, the control unit 210 (future level assignment unit 229) assigns a future level that takes into account the patient influence on the biological information, based on the set level storage unit 44. For example, if the level assigned in the process of S232 is "3", a level "2" obtained by subtracting "1" from the future level is assigned. In S238, the control unit 210 (status output unit 226) outputs a predetermined illustration corresponding to the assigned future level to the touch panel display 47. Thereafter, the control unit 210 moves the process to S241 in FIG.

[0093] The processes from S241 to S244 in FIG. 12 are similar to the processes from S41 to S44 in the first embodiment (FIG. 6). In S245, the control unit 10 (status output unit 226) outputs a predetermined illustration corresponding to the new level assigned in the process of S232 in Fig. 11 to the touch panel display 47. Thereafter, the control unit 210 ends this process.

[0094] In the above flow chart, a predetermined illustration is output. However, as in the first embodiment, an illustration according to the patient's preferences may be output using personality information. Also, an illustration according to the patient's behavior may be selected from life information and output. Furthermore, the cardiac condition at the time when the biological information is acquired and the future cardiac condition may be output as separate screens or may be output on the same screen.

[0095] As described above, the cardiac condition display device 201 according to the second embodiment has the following advantages. In the second embodiment, lifestyle information, which is data relating to the patient's lifestyle, is acquired, and an impact memory unit 246 that stores the impact of the lifestyle on the cardiac condition is referenced to calculate a patient impact based on the acquired lifestyle information. A future level for the future cardiac condition is assigned from a plurality of levels by taking the calculated patient impact into account in addition to the acquired bio-information, and a display mode representing the assigned future level is output to the touch panel display 47. This makes it possible to inform the patient of his / her future heart condition based on his / her lifestyle information, which may serve as an opportunity to encourage the patient to change their behavior, including their lifestyle.

[0096] [Modifications] The allocation of the future level is not limited to data related to the patient's lifestyle. The future level may be allocated based on the patient's knowledge, for example, for living a healthy life or knowledge about heart failure. The knowledge for living a healthy life or knowledge about heart failure refers to, for example, the preferable amount of salt in food, the amount of water to be ingested per day, side effects of medicines, physical symptoms when heart failure worsens, and diseases closely related to heart failure, such as obesity and diabetes. FIG. 13 is a diagram showing an example of the influence degree storage unit 246 of the cardiac condition display device 201 according to the modified example of the second embodiment. The learning achievement level table 246b shown in FIG. 13 is stored in the influence level storage unit 246 and indicates the degree of influence on heart disease of knowledge for living a healthy life and patient knowledge about heart failure.

[0097] This learning achievement table 246b determines the correction coefficient based on the learning achievement based on the test results of the patient who answered the test on knowledge for living a healthy life and knowledge on heart failure, and the risk of death from heart disease. In this modification, the future level is assigned based on the learning achievement based on the test results of the patient. However, instead of the learning achievement of the patient, the correction coefficient may be determined based on the answer rate or correct answer rate in the area in which the patient has a high interest and concern, and the risk of death from heart disease. For example, if the patient has a high interest and concern in the amount of salt in the diet, the answer rate or correct answer rate in the test on the area in which the patient has a high interest and concern will be high. In this case, the risk of the patient developing heart failure by eating a diet with a high salt concentration is reduced, so the correction coefficient of the learning achievement table 246b stored in advance may be modified to assign the future level.

[0098] 11, for example, the cardiac condition display device 201 outputs a test on knowledge for living a healthy life and knowledge on heart failure as processing corresponding to S233, and accepts answers to the test entered by the patient as processing corresponding to S234. Also, the cardiac condition display device 201 calculates the answer rate and the correct answer rate of the accepted answers as processing corresponding to S235. Thereafter, as a process corresponding to S236, the cardiac condition display device 201 calculates the patient influence degree by referring to the learning achievement degree table 246b based on the test result of the patient. The subsequent processing is similar to that in FIGS. The learning achievement level table 246b is merely an example, and this table does not have to be applied to all patients. The patient response rate, correct answer rate and response rate based on the patient's test results, the correction coefficient and the threshold value of the cardiac mortality risk do not have to be set in this way.

[0099] [Modifications] The present invention is not limited to the above-described embodiments, and modifications and improvements within the scope of the present invention that can achieve the object of the present invention are included in the present invention.

[0100] In each embodiment, an example in which an illustration is selected based on personality information has been described, but the present invention is not limited to this. For example, multiple recommended illustration candidates may be output based on personality information, and the patient may select one. Alternatively, the patient may select from all illustrations. Furthermore, a learning model may be used to select the illustrations. More specifically, the combination of personality information and illustrations may be trained in a learning model, and the patient's personality information may be input to the learning model to select the illustrations to be output. Alternatively, a generating AI may be used to create new illustrations that match the patient's preferences.

[0101] Moreover, instead of personality information, illustrations to be displayed may be selected based on the patient's preferences. For example, the cardiac condition display device uses a log to predict the user's preferences from text data entered by the patient and selects an illustration. More specifically, features related to the patient's preferences are extracted from the text data, and the extracted features are input to a machine learning model to learn the preferences. The learned machine learning model is then used to predict the patient's preferences (patient preference information). The cardiac condition display device may create a related illustration based on the prediction result. As a specific example, if the keyword "golf" appears frequently in the text data entered by the patient, an illustration related to golf can be selected.

[0102] Alternatively, illustrations to be displayed may be selected based on the patient's reaction while running the app. For example, the patient's reaction to the content in the app is collected, and the collected reaction data is analyzed to understand the patient's preferences and behavioral patterns (patient preference information). At that time, the collected reaction data may be input into machine learning to understand the patient's preferences and behavioral patterns. As a specific example, if a patient "likes" or enters positive comments on golf-related content, an illustration related to golf can be selected.

[0103] In each embodiment, some illustrations showing the heart state are exemplified, but the present invention is not limited to these. Any other illustrations may be used as long as the illustrations allow the heart state to be intuitively understood. Furthermore, instead of illustrations, videos or the like may be used.

[0104] In each embodiment, an illustration corresponding to the cardiac condition is output on the screen, but a sound representing the cardiac condition may be output. More specifically, when the cardiac condition is improving, a bright sound may be output, and when the cardiac condition is deteriorating, a gloomy sound may be output. The device may also be linked to a model of the patient's heart. Specifically, when the patient's heart condition is improving, a quiet heartbeat sound may be emitted from the patient's heart model, and when the patient's heart condition is deteriorating, an irregular loud heartbeat sound may be emitted from the patient's heart model. The color of the patient's heart model may be changed depending on the patient's heart condition. Furthermore, for example, educational videos according to the level may be output in conjunction with the content. Furthermore, if the heart condition is showing signs of worsening, a procedure screen for receiving counseling or therapy from a specialist may be displayed.

[0105] In each embodiment, a level is set using biological information acquired before surgery and after surgery until discharge from hospital, and the set level is used to assign a level to newly acquired biological information. However, the present invention is not limited to this. For example, the cardiac condition display device may be provided with a control unit (reference point setting means) that sets newly acquired biometric information as a reference point, and if the next acquired biometric information indicates a worse cardiac condition than the reference point, the control unit (level setting means) may set the level (classification) in finer units.

[0106] For example, in the level setting table 44b shown in FIG. 3(B), if the reference point abnormal waveform occurrence rate is 0.8% and the next abnormal waveform occurrence rate obtained from the acquired biological information is 1.0%, multiple new levels are set between level 3 and level 2. By setting finer divisions for when the level drops below the reference point, rather than simply using an equal level setting for pre- and post-operatively, patients are given more opportunities to improve their lost cardiac condition, making the effects of improvement more noticeable.

[0107] In addition, for example, a reference value may be set that predicts that further deterioration of the patient's cardiac condition will be dangerous, and when the cardiac condition level based on new vital signs falls below the reference value, a level division may be made that subdivides the value of the new vital signs from the value above and below the reference value. For example, in the level setting table 44a shown in Fig. 3(A), if the reference value is blood BNP (pg / mL) of 80 and the blood BNP of new biological information is 90, level 2-1 is further set to 95 or more, level 2-2 to 90 or more, and level 2-3 to 85 or more. Here, multiple levels are set between level 2 and level 3, but multiple levels may also be set between other levels.

[0108] By dividing the levels into smaller categories in this way, it is possible to provide the patient with an opportunity to try to improve the cardiac condition that he or she has lost, and to make it easier for the patient to realize the effects of the improvement. In addition, when an illustration is subdivided, it is possible to add stars equal to the number of branch numbers, for example, so that the illustration has a higher level of improvement.

[0109] Moreover, the cardiac condition display device may be provided with a mechanism for resetting the level after the level has been set once. It is known that cardiac conditions generally tend to worsen over time. FIG. 14 is a diagram showing an example of a graph showing a cardiac state according to a modified embodiment. Graph G1 shown in FIG. 14(A) shows general changes in the cardiac condition of a cardiac disease patient over time. It is also known that cardiac rehabilitation can slow the rate at which a heart condition deteriorates. Graph G2 shown in FIG. 14(B) indicates that cardiac rehabilitation improves the heart condition to some extent and slows down the rate of deterioration of the heart condition. However, as shown in graph G2 in Fig. 14(B), even if cardiac rehabilitation is performed, the cardiac condition will gradually deteriorate. Therefore, the level is reset to maintain the patient's motivation to perform cardiac rehabilitation.

[0110] The biological information used as the timing for resetting the level may be, for example, biological information acquired at the time of re-admission with a worsening cardiac condition (e.g., cardiac condition corresponding to A1-2) and biological information acquired when the cardiac condition is stable after treatment or the like (e.g., cardiac condition corresponding to A0-5). In this way, the timing for acquiring biological information for resetting the level may be any time between multiple visits to the hospital or after admission and treatment. In other cases, for example, when newly acquired biological information indicates a worse cardiac condition than the cardiac condition A1, the biological information may be updated as the new cardiac condition A1. In this way, an illustration is displayed showing that the patient's cardiac condition is improving by engaging in even the smallest amount of cardiac rehabilitation, thereby encouraging the patient to continue engaging in cardiac rehabilitation.

[0111] In addition, there may be cases where the biometric information cannot be acquired before surgery, such as in the case of emergency hospitalization and surgery, etc. In such cases, the cardiac condition display device may set the level using the biometric information acquired when the cardiac condition is stable after surgery (e.g., cardiac condition corresponds to A0) and the biometric information acquired when the cardiac condition is deteriorating, such as when the patient is re-admitted (e.g., cardiac condition corresponds to A1-2). The preoperative biological information may be obtained when the patient's heart condition is stable. In this case, it is preferable that the other biological information is obtained when the patient's heart condition is poor. For example, it is preferable to use biological information obtained before the patient is admitted to hospital and receives some treatment (e.g., the heart condition corresponds to A1), or after the patient's heart condition worsens for the second time or later and before the patient is re-admitted to hospital and receives treatment (e.g., the heart condition corresponds to A1-2).

[0112] Furthermore, the timing of acquiring the patient's biological information does not need to be at least one of the periods from post-surgery to discharge from hospital, and may be, for example, a predetermined time after discharge from hospital. As an example, instead of acquiring biological information from post-surgery to discharge from hospital, biological information (e.g., cardiac condition corresponding to A0-4) may be acquired when cardiac rehabilitation is performed after discharge from hospital, and the level may be set. Then, an illustration of a poor cardiac condition may be displayed before this level is set. In this way, it is possible to encourage the patient to undergo cardiac rehabilitation after being discharged from the hospital without displaying an illustration showing a poor cardiac condition.

[0113] In the first embodiment, the biological information of a patient in a bad heart condition is acquired before surgery, and the biological information of a patient in a better heart condition is acquired at least at any timing between after surgery and discharge from hospital. In addition, although examples of biological information acquisition timings different from those in the first embodiment have been shown above, the invention is not limited to these. It is sufficient to acquire two pieces of biological information of the patient's own bad heart condition and biological information of a good heart condition at any timing. As another example, for example, biological information of a patient in a bad heart condition may be acquired before surgery after hospitalization, and biological information of a patient in a good heart condition may be acquired before the heart condition before hospitalization deteriorates.

[0114] In each embodiment, the classification is not particularly limited when setting the levels, but the fineness of the classification of the levels set by the cardiac condition display device and the frequency of message output may be changed based on the patient's personality and behavioral tendencies. Here, the message refers to, for example, text information output by the cardiac condition display device, and may be a pop-up message or the like. In addition, the output frequency of the illustrations (designs) representing the assigned levels displayed on the cardiac condition display device (touch panel display) instead of messages and the notifications regarding the cardiac condition may also be changed based on the patient's personality and behavioral tendencies, or an item in the illustration storage unit 42 may be selected.

[0115] The patient's personality and behavioral tendencies can be understood, for example, from the frequency with which the patient touches the cardiac condition display device, the frequency with which the patient inputs characters, etc. into the cardiac condition display device, the contents of the input, etc., and from the understood patient's personality and behavioral tendencies, for example, a time axis of the patient's behavior can be selected. This utilizes the fact that there is a correlation between the frequency or contents of input, etc., and the time axis of behavior. The time axis of behavior can be, for example, momentary behavior, which is good at short-term and immediate actions; short-term behavior, which is good at actions that take place over a period of about several weeks; medium-term behavior, which is good at actions that take place over a period of several months to a year; and long-term behavior, which is good at continuous actions that last for several years or more. The cardiac condition display device then sets the fineness of the level divisions and the frequency of message output in accordance with the time axis of the selected action.

[0116] Instead of the time axis of the action, the intention of the action, the nature of the action, or the range of the action's influence may be selected. Examples of behavioral intentions include strategic behavior, which is intended to achieve long-term goals; tactical behavior, which is intended to achieve short-term goals and advance specific projects; and operational behavior, which is intended to efficiently carry out daily tasks. In addition, the nature of behavior can include, for example, routine behavior, which is good at daily, standardized behavior; atypical behavior, which is good at non-routine behavior that changes depending on the situation; creative behavior, which is good at behavior that generates new ideas and solutions; and analytical behavior, which is good at behavior that analyzes information and data to gain insight. Furthermore, the scope of influence of actions can include, for example, the individual level, which is good at individual actions; the team level, which is good at actions within a team or small group; the organizational level, which is good at actions that affect the entire organization; and the societal level, which is good at influencing the outside of the organization and society as a whole. However, the above are just examples, and other indicators may be used to grasp the patient's personality and behavioral tendencies.

[0117] In each embodiment, the cardiac condition display device has been described as being provided in a mobile terminal, but this is not limiting. The cardiac condition display device may be configured by multiple devices consisting of a server and a client. In this case, the client may be configured by, for example, a mobile terminal, input and output may be performed by the mobile terminal, or the mobile terminal may include part of the control unit and part of the storage unit.

[0118] In each embodiment, the state of the cardiovascular system of a patient with a heart disease, mainly heart failure, is visualized so that the patient can easily and accurately understand the state, but the present invention is not limited to this. Patients with cardiovascular diseases are also at high risk of having other chronic diseases (e.g., renal failure, diabetes, high blood pressure, etc.), and the state of improvement / worsening of other chronic diseases caused by heart disease may be easily and accurately understood.
