吸烟是中年人冠心病的一个重要危险因素已被许多学者所承认,但老年人吸烟是否对冠心病具有独立的影响,目前尚有争议。鉴于此,作者进行了本次研究。研究对象为美国檀香山市心脏病研究计划中1394名65～74岁的男性(老年组),其中不吸烟者461人,停止吸烟平均14.9年的戒烟者527人,现吸烟者406人,研究对象中不包括已确诊的心血管疾病患者。连续随访12年,观察不同吸烟状况者致死的和非致死的冠心病平均年发病率,并用Cox模型计算出吸烟者患
Smoking is an important risk factor for coronary heart disease in middle-aged people. It has been recognized by many scholars. However, whether smoking in elderly people has an independent effect on coronary heart disease is still controversial. In view of this, the author conducted this study. The research subjects were 1394 65-74-year-old men (elderly group) in the heart study program in Honolulu, USA. Among them, 461 were non-smokers, 527 were smokers who stopped smoking, and 406 were current smokers. Does not include patients diagnosed with cardiovascular disease. Follow-up for 12 consecutive years, observed the average annual incidence of fatal and non-fatal coronary heart disease in different smoking conditions, and calculated the risk of smokers using the Cox model.
