A community based survey of coronary heart disease (CHD) was carried out on a random urban sample of 13,723 adults in the age group 25-64 yr in Delhi, India. CHD was diagnosed either on the basis of clinical history supported by documentary evidence of treatment in a hospital or at home; or on ECG evidence in accordance with the Minnesota Code. The overall prevalence of CHD based on clinical history, was 31.9 (39.5 in males and 25.3 in females) per 1000 adults in this age group. The number of patients with CHD increased with advancing age in both sexes. The total prevalence rate based on both clinical history and ECG criteria (asymptomatic patients with ECG changes of definite myocardial infarction and ST-T changes suggestive of CHD) was estimated as 96.7/1000 adults in this age group. Analysis of information on socio-economic status, family history of CHD, obesity, hypertension and smoking obtained from this sample of 13,723 adults suggested that hypertension had the strongest association with CHD. Obesity, diabetes and family history were also found to be associated with CHD. It should, however, be noted that risk factor assessments in CHD can be done satisfactorily only through incidence studies.
在印度德里，对年龄在25 - 64岁的13723名城市成年人随机抽样，开展了一项基于社区的冠心病（CHD）调查。冠心病的诊断依据如下：一是基于在医院或家中有治疗文件证据支持的临床病史；二是依据明尼苏达编码的心电图证据。基于临床病史，该年龄组每1000名成年人中冠心病的总体患病率为31.9（男性为39.5，女性为25.3）。冠心病患者数量在两性中均随年龄增长而增加。基于临床病史和心电图标准（有明确心肌梗死心电图改变及提示冠心病的ST - T改变的无症状患者）的总患病率估计为该年龄组每1000名成年人中有96.7例。对从这13723名成年人样本中获取的社会经济状况、冠心病家族史、肥胖、高血压和吸烟信息进行分析表明，高血压与冠心病的关联最为密切。还发现肥胖、糖尿病和家族史也与冠心病有关。然而，应当指出的是，冠心病的危险因素评估只有通过发病率研究才能令人满意地完成。
