This study examined risk factors for acute coronary syndrome in 200 patients in Bangladesh compared to 200 controls. Several significant risk factors were identified for the patients compared to controls. These included lower income, more sedentary work, higher rates of smoking tobacco and consuming non-smoke tobacco, lower fruit consumption, higher rates of diabetes, known dyslipidemia, higher waist-hip ratio, and history of heart attack. Multivariate analysis identified the most significant independent risk factors as previous smoking, high waist-hip ratio, history of hypertension, and lower income.
