The study highlights a high prevalence of ischemic heart disease (11.6%) and hypertension (47.2%) among the urban population aged >=40 in Siliguri, strongly associated with smoking and hypertension.
Supports hypothesis generation on IHD risk factors; should not yet change clinical practice.
OBJECTIVES: To determine the prevalence of ischemic heart disease and the associated risk factors among the urban population of Siliguri. MATERIALS AND METHODS: A cross-sectional survey of a random sample of the population aged >/=40 years old in the Municipal Corporation area of Siliguri. Study variables were age, sex, occupation, addiction, food habit, physical activity, body mass index, blood pressure, and electrocardiogram change. RESULTS: Out of 250 individuals who took part in this study, 29 (11.6%) had ischemic heart disease (IHD) and 118 (47.2%) had hypertension. Males had a higher (13.5%) prevalence of IHD than females (9.4%). About 5% of the patients had asymptomatic IHD. IHD among the study population is significantly associated with hypertension and smoking.
