老年冠心病患者的特点和危险因素临床研究

目的：探讨老年冠心病患者的心血管病变特点及相关危险因素。方法：2012年1月～2013年1月我院冠脉造影确诊的130例冠心病患者，被分为老年组（68例，≥60岁）和中年组（62例，＜60岁）。探讨老年冠心病的特点，同时采用 Logistic 回归分析对冠心病的危险因素进行筛选。结果：老年组的冠脉病变≥2支病变者占85.3％，显著高于中年组的48.4％（P＜0.01）。通过 Logistic回归分析得出：年龄、性别、高血压、糖尿病、血脂异常升高为老年冠心病的独立危险因素（OR＝1.268～2.956，P 均＜0.01）。其中性别为最明显独立相关因素（OR＝2.935，P＜0.001）。结论：老年冠心病患者以冠状动脉多支病变为主，年龄、性别、高血压、糖尿病、血脂异常升高为老年冠心病的独立危险因素。

Clinical study for characteristics and risk factors of aged patients with coronary heart disease

Objective：To explore the characteristics and risk factors of aged patients with coronary heart disease （CHD）.Methods：A total of 130 CHD patients,who were diagnosed by coronary angiography in our hospital from Jan 2012 to Jan 2013,were divided into aged group （n=68,≥60 years）and middle-aged group （n=62,〈60 years）.Characteristics of CHD in aged patients were analyzed,while Logistic regression analysis was used to screen risk factors of CHD.Results：The patients with ≥double-vessel coronary disease occupied 85.3% in aged group, which was significant more than 48.4% of middle-aged group （P〈0.01）.Logistic regression analysis indicated that age,gender,hypertension,diabetes mellitus and abnormally elevated blood lipid level were independent risk factors for CHD in aged patients （OR=1.268~2.956,P〈0.01 all）,and gender was the most significant independent risk factor （OR=2.935,P〈0.001）among them.Conclusion：Coronary artery disease is mainly presented as multi-vessel coronary disease in aged patients with coronary heart disease.Age,gender,hypertension,diabetes mellitus and abnormally elevated blood lipid level are independent risk factors for coronary heart disease in aged patients.
