A Cross-Sectional Study of Secondary Prevention Status and Influencing Factors of Stable Angina in 1061 Patients with Coronary Heart Disease
Objective To investigate the current status of secondary prevention of stable angina in patients with coronary heart disease in three regions of China,namely Henan Province,Xinjiang Uygur Autonomous Region,and Tianjin City,and analyze the the influencing factors.Methods A cross-sectional study was conducted to include patients with stable angina with coronary heart disease in Henan,Tianjin and Xinjiang from August 10,2020 to March 14,2021.General information,traditional Chinese medicine(TCM)syndrome elements,prescriptions and other data of patients were collected,and clinical characteristics,blood pressure,blood lipid and blood glucose of patients were analyzed;the patients were divided into groups according to whether their blood pressure,blood lipid and blood glucose were up to standard.With the most common syndrome element as the main variable,region,age and gender as covariables,Logistic regression equation was incorporated to analyze the influencing factors for the patients'blood pressure,blood lipid and blood glucose being up to standard.Results A total of 1061 coronary heart disease patients with stable angina were included,including 658 in Henan,210 in Xinjiang,and 193 in Tianjin.The clinical characteristics of patients in the three regions showed statistical different in age,sex,disease course,complication,blood pressure,blood lipid,blood glucose,smoking,drinking,living habits,and medica-tion treatment(P＜O.05 or P＜0.01).For the included patients,qi deficiency(79.55％,844/1061)and blood stasis(39.96％,424/1061)were the main syndrome elements.The overall compliance rate of blood pressure was 48.89％(506/1035),blood lipids 12.68％(133/1049)and blood glucose 48.18％(504/1046).Qi deficiency was the inde-pendent factor affecting the blood pressure of coronary heart disease patients with stable angina combined with hyper-tension(P=0.029,95％CI[1.048,2.369]),and the independent factors influencing the blood lipid standard of coronary heart disease patients with stable angina(P=0.011,95％CI[1.133,2.646]),but not the independent factors affecting blood glucose standard in coronary heart disease patients with diabetes(P＞0.05).Conclusion Coronary artery disease patients with stable angina have geographical variability in clinical characteristics and distribu-tion of TCM syndrome elements,and the overall control of blood pressure,blood lipids,and blood glucose is poor,and qi deficiency syndrome is an independent risk factor affecting the control of blood pressure and blood lipids.
