Study On TCM Syndrome Types And Related Factors In Patients With Chronic Heart Failure With Different Left Ventricular Ejection Fractions In Changsha Area

Objective:The purpose of this study is to conduct a retrospective study of the distribution of TCM syndromes,characteristics of syndromes and a series of related factors in patients with chronic heart failure of the three types of HEpEF,HEmrEF and HErEF in Changsha,and strive to explore different left ventricular ejection fractions in chronic heart failure.The distribution law of TCM syndrome types,syndrome characteristics and clinical characteristics of decay,provide theory and diagnosis and treatment basis for efficient and reasonable use of TCM treatment and clinical disease prevention,and reduce the rehospitalization rate and mortality of patients with heart failure.Methods:The research members of this study conducted an investigation on the past medical records.193 patients who met the inclusion criteria of this topic were filled in the "Changsha Area Chronic Heart Failure Patient Data Registration Form" to obtain general information of all patients,TCM syndrome type,NYNH Cardiac function classification,NT-proBNP,left ventricular ejection fraction and other related data,make research and analysis database,and use statistical software to perform data statistics on the collected data,analyze the distribution of TCM syndrome types and syndromes of patients with HEpEF,HFmrEF,and HErEF Study on characteristics of weather and series of related factors.Results:1.There are more male patients in the HFrEF,HFmrEF and HFpEF groups than female patients,and the chronic heart failure type is not statistically significant compared with age(P>0.05).2.Patients in the HFrEF group and HFmrEF group are mostly in the age range of 70-79 years,while the patients in the HFpEF group are mostly in the age range of 80-90 years.The age of patients with chronic heart failure with different left ventricular ejection fraction is statistically significant(P<0.05).3.Patients in HFrEF,HFmrEF and HFpEF groups all had coronary heart disease as the primary disease.Chronic heart failure with dilated cardiomyopathy as the primary disease mostly belongs to the HFrEF group.Both HFmrEF and HFpEF have hypertension as the second primary disease.The distribution of primary disease in patients with chronic heart failure with different left ventricular ejection fractions is statistically significant.(P<0.01).4.The cardiac function classification of patients in the HFrEF group is mainly grade Ⅲ and Ⅳ,while the patients in the HFpEF group and HFmrEF group are mainly in the cardiac function grade Ⅲ.The lower the LVEF value,the higher the cardiac function classification,and the chronic ejection fraction is chronic.The classification of heart function in patients with heart failure was statistically significant(P<0.01).5.In the HFrEF group,the number of chronic heart failure patients with different TCM syndromes in descending order was 17 cases of deficiency of both qi and yin(8.8%).15 cases of syndrome of yang deficiency and water flooding(7.8%),and 8 cases of phlegm-drinking obstructive lung syndrome(4.1%),7 cases of qi deficiency and blood stasis syndrome(3.6%),6 cases of heart and lung qi deficiency(3.1%),6 cases of heart and kidney yang deficiency(3.1%);the number of TCM syndromes in the HFmrEF group is from high to low 14 cases(7.3%)of Qi and Yin deficiency syndrome,11 cases of Qi deficiency and blood stasis syndrome(5.7%),7 cases(3.6%)of Phlegm-drinking obstructing lung syndrome,5 cases(2.6%)of cardiopulmonary qi deficiency syndrome,heart and kidney yang deficiency There were 5 cases(2.6%)with syndrome of yang deficiency and water flooding(0.5%);the number of different TCM syndrome types in the HFpEF group was 35(18.1%)of Qi deficiency and blood stasis syndrome,and Qi and Yin deficiency(18.1%).14.0%),15 cases of cardiopulmonary qi deficiency(7.8%),6 cases(3.1%)of yang deficiency and water flooding,and 3 cases(1.6%)of phlegm obstructing the lung.6.The LVEF value of patients with chronic heart failure is negatively correlated with the NT-proBNP value,which is statistically significant(P<0.05).The lower the LVEF value,the higher the NT-proBNP value.7.The symptom score of patients with chronic heart failure with different left ventricular ejection fraction is statistically significant(P<0.01).The lower the left ventricular ejection fraction,the higher the symptom score and the more severe the clinical symptoms.Conclusion:Chronic heart failure patients with different left ventricular ejection fractions have different medical syndromes.With the decrease of LVEF value,the course of heart failure gradually progresses.The syndrome types gradually develop from cardiopulmonary qi deficiency,qi deficiency and blood stasis syndrome to yang deficiency and excessive water syndrome.
