Description

Technical Field

[0001] The present invention relates to the technical field of ischemic heart disease classification, and in particular to an ischemic heart disease classification management system based on multi-level early warning. Background Art

[0002] Myocardial ischemia clinically refers to a pathological state in which the coronary arteries of the heart are narrowed or occluded, resulting in reduced blood supply to the heart, abnormal myocardial energy metabolism, and inability to support the normal functioning of the heart.

[0003] In order to predict the degree of myocardial ischemia in patients, a variety of detection and evaluation methods are usually used clinically, including but not limited to electrocardiogram (ECG), cardiac ultrasound, coronary angiography, and coronary flow reserve fraction (FFR), etc. Among them, FFR is an invasive examination method that evaluates the impact of single coronary artery stenosis on blood perfusion through a pressure guidewire. In the case of microcirculatory lesions or collateral circulation, it cannot accurately reflect the degree of myocardial ischemia in the patient's heart.

[0004] Existing methods for assessing the severity of myocardial ischemia are often based only on the degree of arterial stenosis, or by detecting static electrocardiograms, cardiac ultrasound, coronary angiography and other data to assess the severity of myocardial ischemia in patients. Static assessments focus mainly on the patient's heart condition at rest, but are unable to assess the patient's myocardial ischemia during physical activity load (i.e., exercise) in daily life, and thus are unable to comprehensively assess the patient's risk of myocardial ischemia in real life. Moreover, only based on a single test parameter will lead to inaccurate judgments on the risk level of the patient's condition, and will be unable to grade and classify the patient's disease severity, resulting in poor diagnostic efficiency and treatment effects on the disease. Summary of the invention

[0005] The embodiment of the present invention provides an ischemic heart disease classification management system based on multi-level early warning, which can comprehensively evaluate the patient's cardiac function and myocardial ischemia under different conditions based on multi-dimensional data, and realize the grading and classification of the patient's disease severity.

In the process of judgment, the early warning classification unit can classify the level of the patient's myocardial ischemia based on the various detection data, so as to classify the patient's condition into low risk, medium risk or high risk.

In addition, the present invention can also match the warning standards of different levels according to the patient's detection data, output low-risk, medium-risk or high-risk warning levels, and realize the classification of the patient's disease degree, so that the doctor can understand the severity of the patient's condition more accurately, and provide a basis for formulating personalized treatment plans, thereby improving the diagnostic efficiency and treatment effect of the disease. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 It is a structural schematic diagram of an ischemic heart disease classification management system based on multi-level early warning provided by an embodiment of the present invention.

[0038] Figure 2 It is a structural diagram of a multi-level warning ischemic heart disease classification management system provided by another embodiment of the present invention. DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1 FIG. 1 is a schematic diagram of a structure of an ischemic heart disease classification management system based on multi-level early warning provided by an embodiment of the present invention. The ischemic heart disease classification management system based on multi-level early warning includes: a detection data acquisition unit and an early warning classification unit;

[0041] The detection data acquisition unit is used to acquire detection data of a patient; wherein the detection data includes any one or more of the following combinations: electrocardiogram ischemic state, ventricular arrhythmia detection results, cardiac ultrasound detection results, hemodynamic detection results, stress cardiac ultrasound detection results, peak oxygen uptake of the patient under cardiopulmonary exercise test, and ischemic diagnosis results of the patient under cardiopulmonary exercise test; the electrocardiogram ischemic state includes: a first electrocardiogram ischemic state of the patient under exercise state and a second electrocardiogram ischemic state of the patient during recovery from exercise state to rest state; the ventricular arrhythmia detection result includes: a first ventricular arrhythmia detection result of the patient under exercise state and a second ventricular arrhythmia detection result of the patient during recovery from exercise state to rest state;

[0042] The warning classification unit is used to output the warning level corresponding to the degree of myocardial ischemia of the patient according to the detection data; wherein the warning level includes: low-risk warning level, medium-risk warning level or high-risk warning level.

[0043] In a preferred embodiment, when the warning classification unit of the present invention identifies that the detection data is an electrocardiogram ischemic state, a ventricular arrhythmia detection result, and a cardiac ultrasound detection result, the detection data can be matched with a preset multi-level warning table to output a warning level corresponding to the patient's myocardial ischemia degree;

[0044] Among them, the multi-level warning table includes: a low-risk warning level, a medium-risk warning level and a high-risk warning level; the first ventricular arrhythmia detection result or the second ventricular arrhythmia detection result corresponding to the low-risk warning level is negative, and the left ventricular ejection fraction value of the cardiac ultrasound detection result is greater than the preset score threshold; the first ventricular arrhythmia detection result or the second ventricular arrhythmia detection result corresponding to the medium-risk warning level is negative, and the left ventricular ejection fraction value of the cardiac ultrasound detection result is not greater than the preset score threshold; the first ventricular arrhythmia detection result and the second ventricular arrhythmia detection result corresponding to the high-risk warning level are both positive, and the corresponding first electrocardiogram ischemic state and second electrocardiogram ischemic state are both abnormal states.

[0045] Specifically, based on the preset multi-level warning table, first determine whether the first ventricular arrhythmia detection result or the second ventricular arrhythmia detection result in the detection data is negative, and when it is determined that the first ventricular arrhythmia detection result or the second ventricular arrhythmia detection result is negative, determine whether the left ventricular ejection fraction value of the cardiac ultrasound detection result is greater than the preset score threshold; if so, output that the patient's myocardial ischemia level is a low-risk warning level; if not, output that the patient's myocardial ischemia level is a medium-risk warning level;

[0046] When it is determined that the first ventricular arrhythmia detection result and the second ventricular arrhythmia detection result are both positive, the patient's myocardial ischemia level is output as a high-risk warning level;

[0047] When it is determined that both the first electrocardiogram ischemic state and the second electrocardiogram ischemic state are abnormal states, and both the first ventricular arrhythmia detection result and the second ventricular arrhythmia detection result are positive, the patient's myocardial ischemia level is output as a high-risk warning level.

[0048] Specifically, the system of the present invention first obtains the patient's first ventricular arrhythmia detection result (under exercise state) and the second ventricular arrhythmia detection result (during recovery from exercise state to rest state). If any one of the first ventricular arrhythmia detection result or the second ventricular arrhythmia detection result is normal (i.e., no ventricular arrhythmia, such as ventricular premature beats, ventricular tachycardia, etc.), then proceed to the next step of judgment; if both are abnormal, then directly output that the patient's myocardial ischemia level is a high-risk warning level.

[0049] After determining that any one of the first ventricular arrhythmia detection result or the second ventricular arrhythmia detection result is normal, the system further obtains the patient's cardiac ultrasound test results, especially the left ventricular ejection fraction (LVEF), presets a left ventricular ejection fraction score threshold (such as 50), and compares the LVEF value obtained by cardiac ultrasound detection with the preset score threshold. If the LVEF value is greater than the preset score threshold, it indicates that the left ventricular ejection function is relatively good and the patient's myocardial ischemia is relatively mild, and the output is a low-risk warning level. If the LVEF value is not greater than the preset score threshold, it indicates that the left ventricular ejection function is impaired and the patient's myocardial ischemia is severe, but because the patient has no ventricular arrhythmia and has not yet reached the high-risk standard, the output is a medium-risk warning level.

[0050] Illustratively, when it is determined that both the first electrocardiogram ischemic state and the second electrocardiogram ischemic state are abnormal, and the first ventricular arrhythmia detection result and the second ventricular arrhythmia detection result are also positive, regardless of the LVEF value, the patient's myocardial ischemia level is directly output as a high-risk warning level, because the dual abnormalities of the electrocardiogram and ventricular arrhythmia usually indicate a more serious heart disease state.

[0051] If either the first electrocardiogram ischemic state or the second electrocardiogram ischemic state is normal, the patient is judged to be at a low-risk warning level or a medium-risk warning level based on the comparison result of the LVEF value obtained by cardiac ultrasound detection with the preset score threshold.

[0052] The present invention can more accurately assess the patient's condition by subdividing the degree of myocardial ischemia into three warning levels: low risk, medium risk, and high risk. It not only takes into account the ventricular arrhythmia detection results, but also combines the left ventricular ejection fraction of cardiac ultrasound and the ischemic state of the electrocardiogram, so that the assessment is more comprehensive and accurate. Schematically, for patients with high-risk warning levels, the system can immediately identify and output, so that doctors can quickly take necessary medical measures to prevent the disease from worsening and progressing. For medium-risk and low-risk patients, the system of the present invention can also give clear warning levels, so that doctors can develop personalized treatment plans and follow-up plans.

[0053] Therefore, by comprehensively considering multiple test data, the system of the present invention can reduce misdiagnosis or missed diagnosis caused by abnormal single indicators. For example, even if the patient's electrocardiogram is abnormal in ischemic state, if the ventricular arrhythmia and cardiac ultrasound results are normal, the present invention will evaluate it as a lower warning level, thereby avoiding overtreatment.

[0054] In a preferred embodiment, when the detection data is a hemodynamic detection result and a cardiac ultrasound detection result, the warning classification unit is used to output a warning level corresponding to the degree of myocardial ischemia of the patient according to the detection data, including:

[0055] Determine whether the hemodynamic test result is abnormal. If the hemodynamic test result is abnormal, output that the patient's myocardial ischemia level is a high-risk warning level;

[0056] When the hemodynamic test results are determined to be normal, determine whether the left ventricular ejection fraction value of the cardiac ultrasound test results is greater than the preset score threshold; if so, output the patient's myocardial ischemia level as a low-risk warning level; if not, output the patient's myocardial ischemia level as a medium-risk warning level.

[0057] Specifically, hemodynamic testing is intended to evaluate cardiac function and blood circulation status. First, the patient's hemodynamic data, such as blood pressure (systolic pressure, diastolic pressure, mean arterial pressure), heart rate, cardiac output, blood flow velocity, etc., are collected through hemodynamic monitoring equipment (such as a hemodynamic monitor). The collected data is analyzed to evaluate whether the various hemodynamic parameters are within the normal range. If the hemodynamics are abnormal according to the parameter analysis, the patient's myocardial ischemia is output as a high-risk warning level. If the hemodynamic test result is determined to be normal, the patient is further determined to be at a low-risk warning level or a medium-risk warning level based on the comparison result of the left ventricular ejection fraction value of the cardiac ultrasound test result with the preset score threshold. For example, the LVEF value obtained by cardiac ultrasound is compared with the preset score threshold. If the LVEF value is greater than the preset score threshold, the patient's myocardial ischemia is output as a low-risk warning level. If the LVEF value is not greater than the preset score threshold, the patient's myocardial ischemia is output as a medium-risk warning level.

[0058] The present invention can also combine the results of hemodynamic testing and cardiac ultrasound testing to provide a more comprehensive and accurate early warning classification for the patient's myocardial ischemia degree. Hemodynamic testing provides direct information about the heart's pumping function and blood circulation status, while cardiac ultrasound testing can intuitively evaluate the heart's structure and function, such as the left ventricular ejection fraction (LVEF). The combination of the two can more comprehensively reflect the patient's heart health status, thereby reducing the errors or omissions that may be caused by a single detection method. The embodiment of the present invention improves the accuracy of myocardial ischemia degree early warning through dual verification of hemodynamic parameters and cardiac ultrasound results, thereby being able to more accurately judge the patient's myocardial ischemia degree and avoid misdiagnosis or missed diagnosis.

[0059] In a preferred embodiment, when the detection data is a stress cardiac ultrasound detection result and a patient's peak oxygen uptake under a cardiopulmonary exercise test, the warning classification unit is used to output a warning level corresponding to the patient's myocardial ischemia degree according to the detection data, including:

[0060] Determine whether the stress echocardiography test results are normal;

[0061] When the stress cardiac ultrasound test result is judged to be normal, the patient's myocardial ischemia level is output as a low-risk warning level;

[0062] When the stress cardiac ultrasound test result is determined to be abnormal, determining whether the oxygen uptake peak value is greater than a first preset oxygen uptake threshold value;

[0063] If so, the patient's myocardial ischemia level is output as a low-risk warning level;

[0064] If not, determining whether the oxygen uptake peak value is greater than a second preset oxygen uptake threshold value, if so, outputting that the patient's myocardial ischemia level is a medium-risk warning level, if not, outputting that the patient's myocardial ischemia level is a high-risk warning level;

[0065] Wherein, the first preset oxygen uptake threshold is greater than the second preset oxygen uptake threshold.

[0066] Specifically, firstly, the system can perform stress cardiac ultrasound testing on patients to observe the structural and functional changes of the heart under stress. It can determine whether the stress cardiac ultrasound test results are normal. If the results are normal, it means that the patient's heart function can still maintain a normal level under stress. Then, it can directly output that the patient's myocardial ischemia level is a low-risk warning level.

[0067] If the stress cardiac ultrasound test results are abnormal, a cardiopulmonary exercise test will be performed to measure the patient's peak oxygen uptake.

[0068] The measured peak oxygen uptake is compared with the first preset oxygen uptake threshold. If the peak oxygen uptake is greater than the first preset threshold, it indicates that the patient's cardiopulmonary function is good. Although the stress cardiac ultrasound results are abnormal, it may be caused by other non-serious factors. Therefore, the patient's myocardial ischemia level can be output as a low-risk warning level to avoid overtreatment.

[0069] If the peak oxygen uptake is not greater than the first preset threshold, it will continue to be compared with the second preset oxygen uptake threshold. If the peak oxygen uptake is greater than the second preset threshold but less than or equal to the first preset threshold, it means that the patient's cardiopulmonary function is affected to a certain extent, but has not yet reached a high-risk level. Therefore, the patient's myocardial ischemia level is output as a medium-risk warning level.

[0070] If the peak oxygen uptake is not greater than the second preset threshold, it indicates that the patient's cardiopulmonary function is significantly impaired and there may be severe myocardial ischemia or other heart diseases. Therefore, the patient's myocardial ischemia level is output as a high-risk warning level.

[0071] Stress echocardiography can detect the structural and functional changes of the heart under load, while peak oxygen uptake reflects the maximum capacity of the cardiopulmonary system under aerobic metabolism. The combination of the two can more accurately determine the patient's myocardial ischemia degree and risk level. The present invention can combine the heart structure and function (stress echocardiography) and the overall function of the cardiopulmonary system (peak oxygen uptake) for comprehensive evaluation, so as to more comprehensively reflect the patient's myocardial ischemia degree and heart health status, so as to accurately output the patient's corresponding warning level. Moreover, according to different test results and preset thresholds, it is possible to provide patients with personalized warning levels, which can help doctors develop more targeted treatment plans and rehabilitation plans.

[0072] In a preferred embodiment, when the detection data is the ischemia diagnosis result of the patient under the cardiopulmonary exercise test and the peak oxygen uptake of the patient under the cardiopulmonary exercise test, the warning classification unit is used to output the warning level corresponding to the degree of myocardial ischemia of the patient according to the detection data, including:

[0073] The warning classification unit is used to output that the patient's myocardial ischemia degree is a low-risk warning level when the ischemia diagnosis result is determined to be negative;

[0074] When the ischemia diagnosis result is determined to be positive, determining whether the peak oxygen uptake is greater than a first preset oxygen uptake threshold; if so, outputting that the patient's myocardial ischemia level is a low-risk warning level;

[0075] If not, determine whether the peak oxygen uptake is greater than a second preset oxygen uptake threshold, if so, output that the patient's myocardial ischemia level is a medium-risk warning level, if not, output that the patient's myocardial ischemia level is a high-risk warning level; or,

[0076] It is then determined whether the hemodynamic test results are normal. If so, the patient's myocardial ischemia level is output as a medium-risk warning level. Otherwise, the patient's myocardial ischemia level is output as a high-risk warning level.

[0077] Specifically, the diagnosis is first made based on the patient's ischemic diagnosis results under cardiopulmonary exercise testing;

[0078] If the ischemia diagnosis result is negative, that is, no evidence of myocardial ischemia is detected, the patient's myocardial ischemia level is directly output as a low-risk warning level. If the ischemia diagnosis result is positive, that is, evidence of myocardial ischemia is detected, the next step of determination is performed. First, determine whether the patient's peak oxygen uptake is greater than the first preset oxygen uptake threshold. If the peak oxygen uptake is greater than the first preset threshold, it indicates that the patient's cardiopulmonary function is relatively good. Although myocardial ischemia exists, it may be caused by other non-serious factors. Therefore, the patient's myocardial ischemia level is output as a low-risk warning level. If the peak oxygen uptake is not greater than the first preset threshold, continue to determine whether the peak oxygen uptake is greater than the second preset oxygen uptake threshold. If the peak oxygen uptake is greater than the second preset threshold but less than or equal to the first preset threshold, it indicates that the patient's cardiopulmonary function is affected to a certain extent, but has not yet reached a high-risk level. Therefore, the patient's myocardial ischemia level is output as a medium-risk warning level. If the peak oxygen uptake is not greater than the second preset threshold, it indicates that the patient's cardiopulmonary function is significantly impaired and the degree of myocardial ischemia is severe. Therefore, the patient's myocardial ischemia level is output as a high-risk warning level.

[0079] Furthermore, when the ischemia diagnosis result is positive and the peak oxygen uptake determination is insufficient to clarify the warning level, a determination path based on the hemodynamic test results can be selected to further subdivide the patient's warning level, specifically:

[0080] Determine whether the hemodynamic test results are normal. If the hemodynamic test results are normal, considering that the patient has myocardial ischemia but hemodynamics can still be maintained, the patient's myocardial ischemia level can be output as a medium-risk warning level. If the hemodynamic test results are abnormal, it indicates that the patient's heart function and blood circulation status have been significantly affected, so the patient's myocardial ischemia level is output as a high-risk warning level.

[0081] The early warning classification unit of the present invention can also use the ischemia diagnosis results, peak oxygen uptake and hemodynamic test results of the patient under cardiopulmonary exercise test to determine the early warning level corresponding to the patient's myocardial ischemia degree, which can more comprehensively evaluate the patient's myocardial ischemia degree and improve the accuracy of diagnosis. By early detection and evaluation of the patient's myocardial ischemia degree, it is helpful to intervene and treat early to prevent further deterioration of the disease and the occurrence of adverse consequences.

[0082] In a preferred embodiment, when the detection data is the ischemic state of the electrocardiogram and the peak oxygen uptake of the patient under the cardiopulmonary exercise test, the warning classification unit is used to output the warning level corresponding to the degree of myocardial ischemia of the patient according to the detection data, including:

[0083] When it is determined that the first electrocardiogram ischemic state or the second electrocardiogram ischemic state is a normal state, determining whether the peak oxygen uptake is greater than a first preset oxygen uptake threshold; if so, outputting that the patient's myocardial ischemia level is a low-risk warning level; if not, outputting that the patient's myocardial ischemia level is a medium-risk warning level;

[0084] When it is determined that both the first electrocardiogram ischemic state and the second electrocardiogram ischemic state are abnormal, the patient's myocardial ischemia level is output as a high-risk warning level.

[0085] The present invention combines the electrocardiogram ischemic state and the peak oxygen uptake to make a more detailed classification of the patient's myocardial ischemia degree, thereby outputting a more accurate warning level, so that doctors can formulate a treatment plan that is more suitable for the patient. For example, for patients with normal electrocardiogram ischemic state but low peak oxygen uptake, they are classified as medium-risk warning levels, so that potential myocardial ischemia risks can be detected early, so that early intervention and treatment can be carried out to prevent further deterioration of the disease.

[0086] Electrocardiogram is an important means to evaluate cardiac electrophysiological activity. Myocardial ischemia is often accompanied by specific changes in the electrocardiogram, such as ST segment depression and T wave inversion. These changes can directly reflect the ischemic state of the myocardium and have high specificity. Peak oxygen uptake, as a macroscopic indicator of cardiopulmonary function, can reflect the heart's ability in oxygen supply and consumption. In myocardial ischemia, peak oxygen uptake often decreases due to insufficient myocardial oxygen supply. The ischemic state of the electrocardiogram can directly reflect the electrophysiological abnormality of the myocardium, while peak oxygen uptake can reflect the overall functional state of the heart. The combination of the two can complement each other to form a more comprehensive and accurate evaluation system. Therefore, the evaluation of the ischemic state of the electrocardiogram can more directly reflect the abnormality of the myocardium at the electrophysiological level. At the same time, peak oxygen uptake, as a macroscopic manifestation of cardiopulmonary function, can reflect the heart's ability in oxygen supply and consumption. The combination of the two can more comprehensively evaluate the degree of myocardial ischemia in patients.

[0087] In a preferred embodiment, Figure 2 As shown, the ischemic heart disease classification management system of the present invention further includes: a rehabilitation program generating unit;

[0088] When the detection data is the ischemic state of the electrocardiogram, the ischemic diagnosis result of the patient under the cardiopulmonary exercise test, and the peak oxygen uptake of the patient under the cardiopulmonary exercise test, the rehabilitation program generation unit is used to determine whether the ischemic diagnosis result is negative when the first electrocardiogram ischemic state or the second electrocardiogram ischemic state is determined to be a normal state, and if so, generate a first rehabilitation program; if not, generate a second rehabilitation program; wherein the first rehabilitation program is used to indicate that the patient should undergo high-intensity cardiac rehabilitation therapy and low-intensity myocardial revascularization therapy; the second rehabilitation program is used to indicate that the patient should undergo moderate-intensity cardiac rehabilitation therapy and moderate-intensity myocardial revascularization therapy;

[0089] When it is determined that both the first electrocardiogram ischemic state and the second electrocardiogram ischemic state are abnormal states, it is determined whether the oxygen uptake peak is greater than the second preset oxygen uptake threshold value. If it is greater, a second rehabilitation plan is generated; if it is not greater, a third rehabilitation plan is generated; wherein, the third rehabilitation plan is used to indicate that the patient should undergo low-intensity cardiac rehabilitation treatment and high-intensity myocardial revascularization treatment.

[0090] Indicatively, when generating the first rehabilitation program, if the ischemic state of the first electrocardiogram or the ischemic state of the second electrocardiogram is determined to be normal, and the ischemic diagnosis result is also negative, it means that the patient currently has no significant evidence of myocardial ischemia. However, even if the results of the electrocardiogram and direct ischemic diagnosis (such as myocardial enzymes, cardiac ultrasound, radionuclide myocardial imaging, etc.) are normal, the risk of cardiovascular disease in the future is not completely ruled out, especially for patients with other cardiovascular disease risk factors (such as hypertension, diabetes, hyperlipidemia, smoking history, family history, etc.), then a first rehabilitation program can be generated to characterize that the patient should undergo high-intensity cardiac rehabilitation treatment and low-intensity myocardial revascularization treatment, which indicates a strong recommendation for high-intensity cardiac rehabilitation treatment and a weak recommendation for myocardial revascularization treatment, aiming to reduce the risk of severe cardiovascular disease in the future by improving cardiovascular function, improving cardiopulmonary endurance, and controlling risk factors through cardiac rehabilitation treatment.

[0091] Indicatively, when generating the second rehabilitation program, even if the electrocardiogram shows normal results, if the ischemia diagnosis result is positive, and both the ischemic state of the first electrocardiogram and the ischemic state of the second electrocardiogram are abnormal, and the oxygen uptake peak is greater than the second preset oxygen uptake threshold, it indicates that the patient has myocardial ischemia, or the patient has clear symptoms of myocardial ischemia (such as chest tightness, chest pain, shortness of breath, etc.), then it can be considered that the patient has myocardial ischemia, and a second rehabilitation program can be generated to characterize that the patient should undergo moderate-intensity cardiac rehabilitation treatment and moderate-intensity myocardial revascularization treatment; it can be understood that the second rehabilitation program includes: moderate-intensity cardiac rehabilitation treatment: on the basis of standardized drug treatment, actively adjust lifestyle (such as diet control, quit smoking and limit alcohol, lose weight, etc.), moderate exercise such as aerobic exercise, strength training, flexibility exercises, non-invasive revascularization methods (such as external counterpulsation) and cardiac rehabilitation education, etc., aiming to control cardiovascular disease risk factors, inhibit the progression of arteriosclerosis, improve patients' cardiopulmonary endurance, muscle strength and endurance, and improve cardiovascular health. Moderate-intensity myocardial revascularization therapy includes coronary artery stent implantation, coronary artery bypass grafting or other interventional treatments, and simultaneous standardized drug therapy (such as antiplatelet drugs, statins, etc.), aiming to optimize myocardial perfusion and improve cardiac function, and reduce the occurrence and development of severe myocardial ischemia symptoms and events.

[0092] Indicatively, when generating the third rehabilitation program, when it is concluded that both the first electrocardiogram ischemic state and the second electrocardiogram ischemic state are judged to be abnormal, and the peak oxygen uptake is not greater than the second preset oxygen uptake threshold, a third rehabilitation program is generated to indicate that the patient should undergo low-intensity cardiac rehabilitation therapy and high-intensity myocardial revascularization therapy; it is understandable that, in view of the patient's impaired cardiopulmonary function, the selection of low-intensity cardiac rehabilitation therapy can ensure that the patient will not increase the burden on the heart due to excessive exercise intensity during the rehabilitation process. Since the electrocardiogram shows abnormal myocardial ischemia, this indicates that there is a problem with the heart's blood supply. Therefore, high-intensity myocardial revascularization therapy is adopted to rehabilitate the patient, and high-intensity myocardial revascularization therapy may include coronary artery stent implantation, coronary artery bypass surgery or other interventional treatments, aiming to restore the heart's blood supply, reduce the occurrence of myocardial ischemia, and may improve the patient's overall heart function. Therefore, the third rehabilitation program generated by the present invention indicates a strong recommendation for patients to undergo myocardial revascularization therapy, and a weak recommendation for patients to undergo cardiac rehabilitation therapy, so that through timely and effective myocardial revascularization therapy and appropriate cardiac rehabilitation therapy, the cardiac function of high-risk patients can be significantly improved, and the symptoms of myocardial ischemia can be alleviated or eliminated, thereby improving the quality of life of patients and reducing the pain and inconvenience caused by heart disease.

[0093] In a preferred embodiment, Figure 2As shown, the ischemic heart disease classification management system of the present invention further includes: an exercise program generating unit;

[0094] The exercise program generating unit is used to generate a first exercise program for indicating that the maximum oxygen uptake is within a first preset oxygen uptake range when it is detected that the degree of myocardial ischemia of the patient is at a low-risk warning level;

[0095] When it is detected that the degree of myocardial ischemia of the patient is at a medium-risk warning level, generating a second exercise program for indicating that the maximum oxygen uptake is within a second preset oxygen uptake range;

[0096] When it is detected that the degree of myocardial ischemia of the patient is at a high-risk warning level, generating a third exercise program for indicating that the maximum oxygen uptake is within a third preset oxygen uptake range;

[0097] Among them, the first preset oxygen uptake range is greater than the second preset oxygen uptake range, and the second preset oxygen uptake range is greater than the third preset oxygen uptake range.

[0098] The present invention determines the degree of myocardial ischemia of the patient through comprehensive evaluation, divides it into low-risk, medium-risk or high-risk warning levels, and then presets three different levels of oxygen uptake ranges, corresponding to low-risk, medium-risk and high-risk warning levels respectively. Schematically, different oxygen uptake ranges (such as the first preset oxygen uptake range, the second preset oxygen uptake range, and the third preset oxygen uptake range) are set based on the patient's cardiopulmonary function, exercise endurance and degree of myocardial ischemia.

[0099] According to the patient's myocardial ischemia degree and the preset oxygen uptake range, the system's exercise program generation unit can automatically generate a corresponding exercise program; schematically, each exercise program should include elements such as exercise type, exercise intensity, exercise time, and exercise frequency. In a preferred embodiment, based on the evaluation results of the cardiopulmonary exercise test and related risk assessments, it is recommended that high-risk patients adopt an exercise program that is less than 40% of their maximum oxygen uptake, medium-risk patients adopt an exercise program with a maximum oxygen uptake of 40% to 60%, and low-risk patients adopt an exercise program with a maximum oxygen uptake of 60% to 75%. The precise risk warning grading scheme of the present invention can serve as an important basis for later exercise programs and patient rehabilitation, thereby improving the effectiveness of rehabilitation treatment.

[0100] In a preferred embodiment, when the patient is at a low-risk warning level, the corresponding first exercise plan is: exercise type: mainly aerobic exercise, such as brisk walking, jogging, swimming, cycling, etc.; exercise intensity: medium to high intensity, that is, the heart rate reaches about 60%-75% of the maximum heart rate during exercise; exercise time: 30-60 minutes each time; exercise frequency: at least 5 times a week, which can be adjusted appropriately according to the patient's condition, but regularity and continuity should be maintained.

[0101] When the patient is at the medium-risk warning level, the corresponding second exercise plan is: Exercise type: mainly low-to-moderate intensity aerobic exercise, such as walking or slow walking, gentle yoga, Tai Chi, Ba Duan Jin, etc.; Exercise intensity: low-to-moderate intensity, that is, the heart rate reaches about 50%-60% of the maximum heart rate during exercise; Exercise time: 20-40 minutes each time; Exercise frequency: at least 3-4 times a week, maintain regularity, but the number of exercises can be adjusted appropriately to avoid excessive fatigue.

[0102] When the patient is at a high-risk warning level, the corresponding third exercise plan is: Exercise type: mainly restorative exercises, such as turning over in bed, sitting up, standing, walking and other daily activities, as well as breathing exercises, simple joint movements, etc.; Exercise intensity: low intensity, on the principle of not causing discomfort to the patient and aggravating symptoms; Exercise time: short time each time (such as 5-10 minutes), gradually increasing time and intensity; Exercise frequency: flexibly adjusted according to the patient's condition, but safety and effectiveness should be ensured.

[0103] In summary, the present invention can evaluate and classify the warning level of the patient's myocardial ischemia degree (such as low risk, medium risk, high risk) based on the first electrocardiogram ischemic state, the second electrocardiogram ischemic state, the first ventricular arrhythmia detection result, and the second ventricular arrhythmia detection result of the patient during the exercise state and the recovery from the exercise state to the resting state, as well as the cardiac ultrasound detection result, the hemodynamic detection result, the stress cardiac ultrasound detection result, the patient's peak oxygen uptake and ischemia diagnosis result under the cardiopulmonary exercise test. It can also generate different patient-level rehabilitation programs based on the rehabilitation program generation unit, and it can also generate different patient-level exercise programs based on the exercise program generation unit, thereby realizing that through comprehensive evaluation of multi-dimensional indicators, the specific condition of the patient can be more accurately analyzed, so that the warning level of the degree of myocardial ischemia can be subdivided, and potential heart problems can be discovered earlier, and corresponding preventive measures can be taken. For example, for high-risk patients, monitoring and intervention can be strengthened to reduce the risk of serious cardiac events; for low-risk patients, overtreatment can be avoided and the quality of life can be improved.

[0104] Exercise is an important part of cardiac rehabilitation, but different patients have different cardiac tolerance. The present invention can generate a suitable exercise program according to the patient's myocardial ischemia degree and cardiac function to ensure the safety and effectiveness of exercise, so that the patient can gradually improve his cardiopulmonary function and improve his quality of life during the rehabilitation process.

[0105] The present invention can evaluate the myocardial condition of the target area of ​​the heart, such as the state of ischemic changes, coronary reserve, cardiopulmonary function reserve, exercise tolerance, etc., and realize the transition from static no-load assessment to assessment under different exercise loads and in the recovery period, thereby achieving accurate risk warning stratification, such as screening out the real high-risk groups among patients with ischemic heart disease and recommending them to undergo revascularization treatment, and recommending low-risk groups to undergo cardiac rehabilitation treatment.

[0106] During the early warning evaluation process, the present invention can also perform corresponding load loading methods for patients of different age groups to obtain test data that is more in line with the patient's physical condition, thereby obtaining more accurate early warning analysis results, providing favorable personalized clinical evaluation results for further treatment, avoiding overtreatment, and greatly reducing the medical insurance burden on patients.

[0107] The present invention can utilize medical resources more effectively through accurate assessment and classification. For example, for high-risk patients, expert consultation and advanced examinations can be arranged on a priority basis; for low-risk patients, more economical and effective treatment and management methods can be adopted, thereby reducing the burden on the medical system and improving the overall medical efficiency of ischemic heart disease diagnosis and treatment.

[0108] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
