Description

Technical Field

[0001] The present application relates to the technical field of medical data information processing, and in particular to a method, system and storage medium for monitoring hypertension using a combination of traditional Chinese and Western medicine. Background Art

[0002] The combination of Chinese and Western medicine in monitoring hypertension not only makes use of the scientific and technological advances of modern Western medicine, but also incorporates the traditional Chinese medicine's holistic concepts and individualized treatment methods, providing patients with hypertension with a diverse and comprehensive monitoring program. Because the heart has two states, contraction and relaxation, traditional blood pressure monitoring requires monitoring both systolic and diastolic pressures as a basis for determining hypertension.

[0003] However, human blood pressure has normal physiological changes. For example, blood pressure is lower when sleeping at night, while blood circulation speeds up and blood pressure rises during exercise. Different levels of blood pressure monitoring and analysis should be performed for different human behavioral activities. As a result, the traditional blood pressure monitoring method that only analyzes the blood pressure amplitude is insufficient in monitoring accuracy. At the same time, hypertension may cause the elasticity of the blood vessel wall to deteriorate, thereby weakening the correlation between the changes in systolic and diastolic blood pressure. If the traditional blood pressure monitoring method is used, it is impossible to conduct a more detailed analysis of the monitoring results based on the changing relationship between systolic and diastolic blood pressure, which interferes with the accuracy of blood pressure data processing, further leading to a reduction in the accuracy of blood pressure monitoring and affecting the monitoring effect of hypertension.

[0034] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined invention purpose, the following is a detailed description of the method, system and storage medium for monitoring hypertension by combining traditional Chinese and Western medicine proposed in the present application, its specific implementation method, structure, features and effects, in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0035] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0036] The following is a detailed description of the specific scheme of a method, system and storage medium for monitoring hypertension using a combination of traditional Chinese and Western medicine provided by the present application in conjunction with the accompanying drawings.

[0037] See also Figure 1 , which shows a flowchart of a method for monitoring hypertension using a combination of traditional Chinese and Western medicine provided by an embodiment of the present application, the method comprising the following steps:

[0038] S1, collect the systolic blood pressure, diastolic blood pressure and heart rate of the monitored object at each time of the day during the blood pressure monitoring period.

[0039] In the process of standardized monitoring of hypertension by combined Chinese and Western medicine, the medical team must first conduct pre-monitoring analysis based on the recent blood pressure performance of the monitored subject, and then formulate an appropriate combined Chinese and Western medicine monitoring strategy based on the blood pressure monitoring results.

[0040] The object of blood pressure monitoring is the systolic and diastolic pressures in the arterial blood of patients with hypertension, which refer to the pressure exerted on the vascular wall of the brachial artery of the upper limb by the blood flow during the contraction and relaxation of the heart, respectively, and also correspond to the high and low pressures during the blood pressure monitoring process of the monitored subject.

[0041] Traditional blood pressure monitoring methods often set high and low thresholds for the systolic and diastolic blood pressure of the monitored object. When either the systolic or diastolic blood pressure is higher than the threshold, the monitored object is determined to have a high warning level of hypertension. The accuracy of hypertension monitoring by traditional methods is low. Therefore, this embodiment combines the scenario to perform more accurate hypertension monitoring of the monitored object, and then the medical team formulates a more appropriate standardized hypertension monitoring strategy combining traditional Chinese and Western medicine.

[0042] First, a blood pressure monitoring cycle is preset. In this embodiment, the blood pressure monitoring cycle is one week. The implementer can set it according to the actual situation, and this embodiment does not limit it here. The systolic and diastolic blood pressure data of the monitored object at each time of the day during the blood pressure monitoring cycle are read by the dynamic blood pressure monitor, and the heart rate data of the monitored object at each time of the day during the blood pressure monitoring cycle is read by the heart rate monitor. In this embodiment, the collection time intervals of the systolic and diastolic blood pressure data and the heart rate data are all 1s. The implementer can set it according to the actual situation, and this embodiment does not limit it here.

[0043] S2, based on the prominence of systolic blood pressure at each time of the day, determine the extent of blood pressure increase at each time of the day; analyze the difference between the heart rate at each time of the day and the average heart rate to determine the heart rate activity reflection at each time of the day.

[0044] The higher the blood pressure amplitude of the monitored subject, the more significant the hypertension of the monitored subject. Considering that the behavioral activity of the monitored subject is related to the confidence of the blood pressure amplitude in reflecting the hypertension, for example, when sleeping at night, the human body's behavioral activity is low, and the confidence of the blood pressure level at this time is higher; while during daytime exercise, the human body's behavior is more active, blood circulation is accelerated, and blood pressure may rise. At this time, the confidence of the normal physiological increase in blood pressure in reflecting the hypertension is low. Therefore, the degree of high blood pressure of the monitored subject is evaluated based on the behavioral activity reflected by the heart rate data and the blood pressure amplitude.

[0045] First, the systolic and diastolic blood pressures of the monitored subjects at each time of the day during the blood pressure monitoring cycle are analyzed. Taking systolic blood pressure as an example, if the blood pressure amplitude at a certain moment is closer to the hypertension threshold or larger than the hypertension threshold, the more significant the characteristic of the blood pressure tending to hypertension at that moment is. Therefore, the blood pressure tendency amplitude at each time of the day during the blood pressure monitoring cycle of the monitored subjects is calculated. The specific calculation method is:

[0046] ; In the formula, is the blood pressure increase amplitude of the monitored object at the jth moment on the i-th day during the blood pressure monitoring period, is the systolic blood pressure amplitude at the jth moment on the i-th day during the blood pressure monitoring cycle of the monitored object, represents the hypertension threshold of systolic blood pressure, norm[] is the normalization function, and e is a natural constant.

[0047] It should be understood that the hypertension threshold can be obtained from common knowledge. ; It is the difference between the preset hypertension threshold and the systolic blood pressure amplitude at the jth moment on the i-th day. The difference represents the degree of difference between the two variables. It can be calculated by difference, absolute value of difference, square of difference, ratio, etc. This embodiment does not limit this.

[0048] Secondly, if the monitored subject's heart rate is more active, it means that the increase in blood pressure is more likely to come from normal physiological activities rather than pathological causes, so we continue to analyze the degree of behavioral activity reflected by the monitored subject's heart rate. Calculate the degree of heart rate activity reflection of the monitored subject at each time of the day. The specific calculation method is:

[0049] ; In the formula, is the heart rate activity reflection degree of the monitored object at the jth moment on the i-th day during the blood pressure monitoring cycle, is the heart rate of the monitored object at the jth moment on the i-th day during the blood pressure monitoring cycle, is the mean heart rate of the monitored subject at all times on the i-th day during the blood pressure monitoring period.

[0050] It should be understood that if the heart rate amplitude of the monitored object at the jth moment is higher than the average level, the monitored object at the jth moment is more likely to be in a state with a certain degree of activity, and the heart rate activity reflection degree at the jth moment is greater.

[0051] S3, analyzing the variation of the heart rate in the local time period at each time of the day, and combining the heart rate activity reflection degree to determine the behavioral activity at each time of the day; combining the blood pressure increase amplitude with the behavioral activity degree to obtain the degree of blood pressure increase at each time of the day.

[0052] In this embodiment, all moments within 1 minute before each moment are taken as adjacent moments of each moment and recorded as the local time period of each moment. The implementer can set the adjacent moments of each moment according to the actual situation, and this embodiment does not limit this.

[0053] The least squares method is used to obtain the fitting curve of the heart rate of the monitored object at all times of the day during the blood pressure monitoring period, and the slope of the heart rate at each time of the day corresponding to the fitting curve, that is, the rate of change, is calculated to calculate the behavioral activity of the monitored object at each time of the day. The specific calculation method is:

[0054] ; In the formula, is the behavioral activity of the monitored subject at the jth moment on the i-th day during the blood pressure monitoring period, is the mean value of the slope at the jth moment and its adjacent moments on the i-th day in the blood pressure monitoring cycle of the monitored subject, is the minimum value of the slope at all times of the i-th day in the blood pressure monitoring cycle of the monitored subject, is the maximum value of the slope at all times of the i-th day in the blood pressure monitoring cycle of the monitored subject, is the heart rate activity reflection degree at the jth moment on the i-th day in the blood pressure monitoring cycle of the monitored object. Among them, the least square method is a well-known technology, and the implementer can choose other feasible curve fitting algorithms according to the actual situation, and this embodiment is not limited here. Recorded as the first difference, Recorded as the second difference, Recorded as heart rate change ratio.

[0055] It should be noted that, when the average slope level of the monitored object's heart rate at each moment and its adjacent moments is greater, it means that the monitored object's heart rate rises faster and the monitored object's heart rate activity reflection is higher, indicating that the monitored object is more likely to have more intense behavioral activities at this time and the greater the behavioral activity.

[0056] Furthermore, the higher the behavioral activity of the monitored subject at a certain moment, the more the increase in blood pressure at that moment is affected by normal physiological activities, and the higher the blood pressure at that moment is. The confidence level reflecting the characteristics of hypertension is reduced. Therefore, the degree of high blood pressure trend of the monitored object at each time of the day is calculated. The specific calculation method is:

[0057] ; In the formula, is the degree of high blood pressure at the jth moment on the i-th day during the blood pressure monitoring period of the monitored object, is the behavioral activity of the monitored subject at the jth moment on the i-th day during the blood pressure monitoring period, is the blood pressure increase amplitude of the monitored object at the jth moment on the ith day during the blood pressure monitoring period, and norm() is the normalization function.

[0058] It should be understood that the greater the degree of high blood pressure, the more obvious the hypertension characteristics of the monitored subject are, and the greater the need for hypertension monitoring.

[0059] S4, analyzing the periodic changes in the degree of the high blood pressure trend at the same time of each day compared with other days, and determining the periodic significance at each time of each day; analyzing the systolic blood pressure at each time of each day and the distribution of its related systolic blood pressure, and determining the excellence of the systolic blood pressure at each time of each day in combination with the periodic significance and the degree of the high blood pressure trend.

[0060] Considering that human life activities have periodic regularity in similar time periods every day, blood pressure data will show similar patterns in similar time periods every day. At the same time, hypertension will make blood pressure changes sensitive, that is, the local fluctuation characteristics of blood pressure are more significant every day. Therefore, the collected systolic blood pressure data are analyzed according to the stable fluctuations of blood pressure within each day and the periodic characteristics of blood pressure over multiple days. Furthermore, hypertension will weaken the correlation between systolic and diastolic blood pressure, so the analysis is combined with the correlation characteristics of systolic and diastolic blood pressure.

[0061] First, for the degree of blood pressure increase at each moment of the monitored object every day, the degree of blood pressure increase at the same moment of all days in the blood pressure monitoring period is extracted. If the degree of blood pressure increase at a certain moment is more similar to that at the same moment of other days, it means that the blood pressure periodicity at that moment is good. Therefore, the period significance of the monitored object at each moment of every day is calculated. The specific calculation method is:

[0062] ; In the formula, is the cycle significance at the jth moment on the i-th day during the blood pressure monitoring cycle of the monitored object, is the degree of high blood pressure at the jth moment on the i-th day during the blood pressure monitoring period of the monitored object, is the degree of high blood pressure at the jth moment on the rth day excluding the i-th day during the blood pressure monitoring period of the monitored object, M is the number of days in the blood pressure monitoring period, and norm() is the normalization function.

[0063] The better the periodicity of the blood pressure of the monitored object at each moment and the greater the significance of the period, the greater the possibility that the blood pressure of the monitored object is normal and the more accurate the monitoring of hypertension is.

[0064] At the same time, sensitivity to changes in blood pressure is also a significant manifestation of hypertension, so the degree of change in the systolic blood pressure of the monitored object can be analyzed in combination with the stable characteristics of blood pressure fluctuations throughout the day. Specifically: the systolic blood pressure data of the monitored object at all times of the day are clustered using the K-means clustering algorithm, wherein the number of clusters K is determined by the elbow method, and the systolic blood pressure data of the monitored object at all times of the day are divided into clusters. The K-means clustering algorithm and the elbow method are both existing public technologies, and the specific process will not be repeated here. The implementer can choose other existing feasible clustering algorithms according to actual conditions, and this embodiment is not limited here. Calculate the blood pressure stability of the monitored object at each time of the day, and the specific calculation method is:

[0065] ; In the formula, is the blood pressure stability of the monitored object at the jth moment on the i-th day during the blood pressure monitoring cycle, is the degree of dispersion of all systolic blood pressure data in the cluster where the systolic blood pressure at the jth moment on the i-th day during the blood pressure monitoring period of the monitored object is located, and norm() is the normalization function.

[0066] It should be noted that the degree of dispersion can be specifically calculated by using variance, standard deviation, coefficient of variation, etc., and this embodiment uses standard deviation as the calculation method for the degree of dispersion. The smaller the degree of dispersion, the more concentrated and stable the systolic blood pressure distribution of the monitored object at the jth moment is, the smaller the fluctuation is, and the greater the blood pressure stability is.

[0067] Furthermore, if the blood pressure stability at a certain moment is greater, the blood pressure cycle significance is higher, and the blood pressure trend is lower, it means that the blood pressure performance at that moment is better and the blood pressure of the monitored object is more normal. Therefore, the systolic blood pressure performance excellence of the monitored object at each moment of the day is calculated. The specific calculation method is:

[0068] ; In the formula, is the systolic blood pressure performance excellence of the monitored object at the jth moment on the i-th day during the blood pressure monitoring period, is the blood pressure stability of the monitored object at the jth moment on the i-th day during the blood pressure monitoring cycle, is the cycle significance at the jth moment on the i-th day during the blood pressure monitoring cycle of the monitored object, It is the degree of high blood pressure trend at the jth moment on the i-th day during the blood pressure monitoring period of the monitored object.

[0069] S5, based on the diastolic pressure, determine the diastolic pressure performance excellence at each time of the day, and combine the systolic pressure performance excellence at all times of the day with the diastolic pressure performance excellence to obtain a comprehensive blood pressure excellence for each day.

[0070] The diastolic blood pressure of the monitored object at each time of the day is calculated using the same calculation method as the systolic blood pressure to obtain the diastolic blood pressure performance excellence of the monitored object at each time of the day during the blood pressure monitoring period.

[0071] The average of the systolic blood pressure performance excellence at all times of the day and the diastolic blood pressure performance excellence at all times of the day during the blood pressure monitoring period of the monitored subject is taken as the comprehensive blood pressure excellence of the monitored subject every day during the blood pressure monitoring period.

[0072] The greater the comprehensive blood pressure excellence, the more normal the daily blood pressure of the monitored subject is, and the higher the accuracy of hypertension monitoring is.

[0073] S6, based on the difference between systolic and diastolic blood pressure at each time of the day, obtain the pulse pressure difference at each time of the day, analyze the difference between the pulse pressure difference at all times of the day and the average pulse pressure difference, determine the blood pressure correlation degree of each day, and combine the comprehensive blood pressure excellence to obtain the correlation excellence of each day.

[0074] Furthermore, the systolic and diastolic blood pressures of the monitored subjects at each time of the day during the blood pressure monitoring cycle are subtracted to obtain the pulse pressure difference at each time of the day. Since high blood pressure may cause the elasticity of the blood vessel wall to deteriorate, thereby weakening the correlation between the changes in systolic and diastolic blood pressures, the correlation between the systolic and diastolic blood pressures of the monitored subjects is analyzed, and the correlation degree of the monitored subjects' blood pressures is calculated. The specific calculation method is:

[0075] ; In the formula, is the blood pressure correlation degree of the monitored object on the i-th day during the blood pressure monitoring period, is the pulse pressure difference at the cth moment on the ith day during the blood pressure monitoring cycle of the monitored object, is the mean pulse pressure difference at all times during the i-th day of the blood pressure monitoring cycle of the monitored object, and N is the number of collection times during the i-th day of the blood pressure monitoring cycle of the monitored object.

[0076] It should be understood that if the pulse pressure difference data at each time of the day are more discrete compared to the mean level, it means that the pulse pressure difference fluctuation of the monitored object is more significant, which means that the correlation between the changes in systolic and diastolic blood pressure is worse, and the blood pressure correlation degree is lower.

[0077] Finally, if the correlation between systolic and diastolic blood pressure is higher, and the comprehensive blood pressure excellence is greater, it means that the correlation excellence of blood pressure obtained based on the blood pressure correlation relationship is better. Therefore, the correlation excellence of the monitored object is calculated every day. The specific calculation method is:

[0078] ; In the formula, is the correlation excellence of the i-th day in the blood pressure monitoring period of the monitored object, is the blood pressure correlation degree of the monitored object on the i-th day during the blood pressure monitoring period, It is the comprehensive blood pressure excellence of the monitored object on the i-th day during the blood pressure monitoring period.

[0079] If the correlation excellence of the monitored object is greater every day and the change is more stable, it means that the blood pressure of the monitored object is more normal.

[0080] S7, analyzing the changing trend of the correlation excellence of all days in the blood pressure monitoring period, obtaining the hypertension warning value of the monitored object, and performing hypertension monitoring on the monitored object.

[0081] The hypertension warning value of the monitored object is obtained based on the time domain change trend of the correlation excellence of the monitored object every day. If the correlation excellence of the monitored object shows a sharp decreasing trend in the time domain during the blood pressure monitoring period, it means that the hypertension monitoring warning level at this time is higher, and the hypertension warning value is set accordingly.

[0082] First, with the number of days as the horizontal axis and the daily correlation excellence of the monitored object as the vertical axis, the least squares method is used to perform straight-line fitting on the correlation excellence of all days in the blood pressure monitoring period of the monitored object to obtain the slope of the fitting line.

[0083] If the slope of the fitting straight line is smaller, it means that the downward trend of the correlation excellence is more obvious. At the same time, the smaller the mean value of the correlation excellence is, the higher the degree of hypertension monitoring warning is. Therefore, the hypertension warning value of the monitored object is calculated as follows:

[0084] ; In the formula, is the hypertension warning value of the monitored object, is the slope of the fitting line, is the correlation excellence of the i-th day in the blood pressure monitoring cycle of the monitored object, M is the number of days in the blood pressure monitoring cycle, and norm() is the normalization function. The flowchart for determining the hypertension warning value is as follows: Figure 2 shown.

[0085] Based on the hypertension warning value of the monitored object, a reference basis is provided for the joint monitoring of hypertension by Chinese and Western medicine, and the hypertension monitoring of the monitored object is completed.

[0086] Based on the same inventive concept as the above method, an embodiment of the present application provides a storage medium for monitoring hypertension with combined traditional Chinese and Western medicine, wherein the medium stores a computer program, and when the computer program is executed by a processor, the method for monitoring hypertension with combined traditional Chinese and Western medicine as described in any one of the above items is implemented.
