title: An epidemiological study of coronary heart disease in different ethnic groups in Delhi urban population.
abstract: A community based epidemiologival survey of coronary heart disease (CHD) was carried out on a random urban sample of 13,560 adults of different ethnic groups in Delhi. CHD was diagnosed either on the basis of clinical history, supported by documentary evidence of treatment in hospital/home or on the ECG evidence in accordance with Minnesota Code. The prevalence rate of CHD on clinical basis per 1000 adults was the highest in Sikhs (47.3), lowest in Muslims (22.8) and identical in Hindus (31.8) and Christians (31.2). The prevalence rate/1000 of silent CHD on the basis of ECG was high in Muslims (89.5) and Sikhs (87.3), low in Christians (25.0) and intermediate in Hindus (60.0). The Sikhs showed the highest prevalence rate of myocardial infarct (MI) (15.5) and angina (AP) (31.8) compared to other communities. The prevalence rate of CHD on clinical basis was higher in males than females in all communities. The prevalence of silent CHD was higher in females in Hindus and Sikhs but in Muslims it was higher in men (94.8) than in women (85.2). The wide variations in prevalence rates of CHD in different ethnic groups cannot be explained satisfactorily on the basis of conventional risk factors and support the multifactorial etiological character of CHD.
