| Unstable angina pectoris is a group of clinical syndromes between stable angina pectoris and acute myocardial infarction in acute coronary syndrome of coronary heart disease.With the continuous progress of China's economy,the incidence of coronary heart disease is increasing year by year,of which unstable angina pectoris occupies a large proportion in acute cardiovascular events,which has attracted extensive attention from the medical community and all sectors of society.In the study of unstable angina,traditional Chinese medicine has great advantages in the treatment of unstable angina.Integrated treatment of traditional Chinese and western medicine can significantly improve various symptoms,can improve the quality of life of patients,and traditional Chinese medicine dialectical nursing for improving the prognosis of patients also has a very obvious effect.Therefore,objectification and standardization of unstable angina pectoris are of great significance for clinical diagnosis and treatment.Cardiac impingement graph is a new detection instrument in the field of medical physics.Previous studies have confirmed the correlation between different syndromes of CHD heart failure and CHD angina.Based on this,I will try to study the differences between different syndromes of unstable angina pectoris from the waveform signals of cardiac impingement diagram on the basis of previous studies,so as to provide a basis for Chinese medicine to explore the obj ectification of different syndromes of coronary heart disease,and thereby improve the clinical efficacy.Objectives:1.To study the differences between the main indexes of male and female impact ballistocardiogram,explore and analyze the characteristic waveform indexes of male and female impact ballistocardiogram data,and lay a data foundation for the later research of the impact ballistocardiogram;2.Study the differences of the main indicators(H,I,J,K,tHI,tIJ,tJK,etc.)of different types of ballistocardiogram to verify the feasibility of the evaluation of unstable angina pectoris syndrome by ballistocardiogram;3.To study the differences between the waveform data of HIJKL and the TCM syndromes,so as to establish the correlation between the TCM syndromes and the indicators of the ballistocardiogram,and further promote the clinical research and application of the ballistocardiogram.Methods:From January 2018 to March 2019,101 patients diagnosed with unstable angina pectoris in the cardiovascular medicine ward of dongfang hospital of Beijing university of traditional Chinese medicine were selected as study subjects.The diagnostic criteria of western medicine refer to the guidelines for the diagnosis and treatment of unstable angina pectoris and non-st-segment elevation myocardial infarction published by the Chinese society of cardiology and the editorial board of Chinese journal of cardiovascular diseases in 2007.TCM syndrome differentiation refers to the guiding principles for clinical research of new TCM drugs issued by the state drug administration in 2002,and four common syndromes are selected,namely blood stasis,qi deficiency and blood stasis,qi stagnation and blood stasis,and phlegm obstruction of the heart and veins.Because gender is the key to affect data,this study is divided into two groups according to the research objects:male group and female group.According to the syndrome types,it can be divided into 8 subgroups:the male group of xinmaibi obstruction,the male group of qi-deficiency and blood stasis,the male group of qi-stagnation and blood stasis,the male group of phlegm obstruction and xinmai obstruction,the female group of xinmaibi obstruction,the female group of qi-deficiency and blood stasis,the female group of qi-stagnation and blood stasis,and the female group of phlegm obstruction and xinmai obstruction.By myself,the enrolled patients were collected for the cardiac impingement signal after admission.The waveform data analyzed by the department of engineering physics of tsinghua university will be recorded.SPSS20.0 was used for statistical processing of the data.The measurement data were expressed as(x s),Levene test was used to test the homogeneity of variance,and statistical t test was used to compare the differences of characteristic values between each group and subgroups.P<0.05 was considered statistically significant.F test or nonparametric test was used for multigroup mean comparison,and LSD test was used for further pairwise comparison.Frequency distribution and histogram were selected for data features.Results:1.Compared with the female group,p<0.05 was found in the data of H,J,K,tHI,tIJ and tJK,indicating a statistically significant difference.2.In the amplitude of J wave,the difference between the male group and the female group in qi deficiency and blood stasis was statistically significant(p<0.05)compared with that in the qi stagnation and blood stasis group,phlegm obstruction and heart pulse group and blood stasis group.3.The j-wave amplitude of qi deficiency and blood stasis syndrome in the male group and the female group was significantly smaller than that in the qi stagnation and blood stasis group,phlegm obstruction and heart pulse group,and blood stasis and blood stasis group.The tHI and tUK of qi deficiency and blood stasis were larger than those of other syndromes.4.In the comparison of HI stage,the difference between the male group and the female group in qi deficiency and blood stasis was statistically significant(p<0.05)compared with the group of qi stagnation and blood stasis,phlegm obstruction and heart vessels,and blood stasis of blood vessels.5.The HI interval of qi deficiency and blood stasis in the male group and the female group was greater than that in the qi stagnation and blood stasis group,phlegm obstruction and heart pulse group and blood stasis group.6.In the comparison of JK interval,the difference between the male group and the female group was statistically significant(p<0.05)compared with the groups of qi stagnation and blood stasis,phlegm obstruction and heart arteries,and blood stasis of blood vessels.7.The JK interval of qi deficiency and blood stasis in the male group and the female group was greater than that in the qi stagnation and blood stasis group,phlegm obstruction and heart vein group and blood stasis group.Conclusions:1.There are significant differences between male patients and female patients in H,J,K,tHI,tIJ and tUK.2.The syndrome types of qi deficiency and blood stasis of male patients and female patients are different from those of qi stagnation and blood stasis,phlegm obstruction of the heart and veins,and blood stasis of the blood in J,tHI and tUK;3.Different types of unstable angina have different waveforms of ballistocardiogram:the amplitude of j-wave of qi deficiency and blood stasis is smaller than that of qi stagnation and blood stasis,phlegm obstruction of the heart and blood stasis,while tHI and tJK of qi deficiency and blood stasis are larger than that of qi stagnation and blood stasis,phlegm obstruction of the heart and blood stasis.It is feasible to use shock ballistocardiogram as the syndrome of unstable angina pectoris. |
