Background: Coronary heart disease (CHD) is a major health problem which imposes a significant burden on health caresystems because of high morbidity and mortality. Objectives: To compare the risk factors profile for coronary heartdisease in young and old subjects. Methods: Total 100 patients (50 subjects less than 40 years of age and 50 subjectsmore than 40 years of age) with acute coronary syndrome or stable angina who were undergoing coronary angiogram inthe Department of Cardiology, University Cardiac Center, Bangabandhu Sheikh Mujib Medical University Dhaka, fromJuly 2006 to June 2008 were evaluated for the presence coronary artery disease risk factors e.g. hypertension, dyslipidemiaand smoking. Results: The mean age of the study population in younger group was (33.0 ± 6.4) years and in older group(52.0±8.6). The male to female ratio in both groups was 4:1. Smokers were more in younger group (70.0% vs. 46.0%) (p =0.032). Hypertension was less in the younger group (38.0% vs. 58.0%) (p = 0.045). Presence of diabetes was higher in theolder age group (34.0% vs. 4.0%) (p = 0.001). Higher incidence of family history of coronary heart disease was in theyounger age group. The total cholesterol was higher in older group (182.9 ± 33.1) vs. (171.1 ± 24.8 mg/dl) (p = 0.047). 68%of patients of older group and 38% of younger group had stenosis in left anterior descending artery (p = 0.003). Theinvolvement of left circumflex and right coronary artery in older age group were higher (56% and 66% respectively) thanthose in younger group (36% and 40% respectively) (p = 0.045 and p = 0.009). Conclusion: Ischemic heart disease inyounger adults < 40 years had different risk profile characteristics than older patients.Key words: Coronary heart disease; acute coronary syndrome; stable angina; risk factors.DOI: 10.3329/bsmmuj.v3i1.5508BSMMU J 2010; 3(1): 13-17
