Analysis of risk factors and the prognostic risk factors in aged patients with coronary heart disease / 心血管康复医学杂志

ABSTRACT

Objective:To analyze risk factors and prognostic risk factors in aged patients with coronary heart disease (CHD).Methods:Clinical data of 412 aged patients,who were suspected of CHD in our hospital,were retrospec-tively analyzed.According to results of coronary angiography,they were divided into CHD group (n=283 )and non-CHD group (n=129);risk factors and prognostic risk factors for aged CHD patients were analyzed.Results:Compared with non-CHD group,there were significant rise in percentages of >80 years (13.95% vs.28.98%),di-abetes mellitus (DM,37.98% vs.66.78%)and smoking history (32.56% vs.59.72%)in CHD group,levels of to-tal cholesterol [TC,(5.06±1.53)mmol/L vs.(5.41±1.36)mmol/L],triglyceride [TG,(1.53±0.82)mmol/L vs.(2.02±0.95)mmol/L]and low density lipoprotein cholesterol [LDL-C,(2.05±0.86)mmol/L vs.(2.57 ±1.15)mmol/L],and significant reduction in high density lipoprotein cholesterol level [HDL-C, (1.65 ±0.52) mmol/L vs.(0.86±0.38)mmol/L]in CHD group,P <0.05 or <0.01. Multi-factor Logistic regression analysis indicated that age,DM,hypertension history,smoking,high total cholesterol (TC)and hypertriglyceridemia were independent risk factors for CHD (OR= 1.38 ~8.65,P <0.05 or <0.01 );while serum total bilirubin and high density lipoprotein cholesterol were independent protective factors for CHD (OR=0.224,P =0.002);multi-factor Cox model analysis indicated that smoking history,high TC and hypertension were risk factors affecting prognosis of CHD patients (RR= 1.563 ~ 2.315,P < 0.05 all).Conclusion:In clinic,attention should be paid to reduce or eliminaterelated risk factors of aged CHD patients to improve prognosis.
