Background: Various studies have shown that people of Indian origin have an increased risk of ischemic heart disease (IHD) compared with most other ethnic groups. This increased risk has been attributed to multiple risk factors related to lifestyle. Patients and Methods: A total of 100 cases and 100 age and sex-matched controls were taken into this prospective case-control study from Intensive Coronary Care Unit. Prevalence of the following risk factors for myocardial infarction: Age, sex, diet, smoking, alcohol consumption, history of hypertension, history of diabetes mellitus, and lipid profile were studied. Patient data were extracted from the medical records department and by interview. Results: The most important predictor of acute myocardial infarction (AMI) was high low-density lipoprotein (adjusted odds ratio [OR]: 4.124, confidence interval [CI]: 1.44-11.73, P = 0.008) history of hypertension and of overt diabetes mellitus were also independent risk factors (OR: 2, CI: 1.4-3 and OR: 2.29, CI: 1.5-3.5), respectively. Low high-density lipoprotein was found to have no significant association with AMI. Heavy drinkers were found to have a high-risk (OR: 68), while moderate drinkers were found to have protection (OR: 1). Conclusion: Smoking and heavy drinking cessation, treatment of hypertension and reduction in blood glucose, correction of abnormal lipid profile either through use of statins or by dietary modification may be important in preventing IHD in Asian Indians.
