Coronary Heart Disease among the Patients of Age between 25-39 and 40-70 Years Attending Cardiology Outdoor of BSMMU, Dhaka, Bangladesh

Background: Ischemic heart disease (IHD), also known as Coronary Heart Disease (CHD) is a generic designation for a group of related syndromes resulting from myocardial ischemia. It comprises of stable angina, unstable angina, acute myocardial infarction and sudden death. Since the most common cause of IHD is coronary artery abnormality it is also termed as “Coronary artery disease”. Method: This cross sectional observational study was carried out in the department of Cardiology, UCC, BSMMU, Dhaka, during the period of September 2013 to December 2013. A total of 200 patients with primary diagnosis of CHD who were admitted for coronary angiogram were included in this study considering the inclusion and exclusion criteria. Results: Patients aged 25 to 40 years were grouped as group A and a 40 to 70 years were grouped as group B. Baseline clinical history, physical examination and investigations including reports of coronary angiogram were recorded accordingly. There were significant differences between two groups in respect to risk factors and angiographic findings. The prevalence of hypertension and diabetes were found to be more among group B CHD patients compare to group A patient (p<0.001) while, smoking and positive family history of IHD were more prevalent in younger age group (p<0.05). Normal or non-significant CAG findings were more common among group A compared to group B (p<0.05). Multiple vessel disease was observed to be more common amongst group B CHD patients (p<0.01). LAD and RCA involvement was more frequent in group B compared to group A patient (p<0.01). This indicated that risk factors and disease severity was different between two groups. In both the groups male predominance was observed but it was not different between two groups. Other risk factors like obesity and dyslipidemia were not found to be different. Conclusion: Even with best possible effort some limitations have been encountered in this study. Emerging risk factors we discussed .......
