Objective: This study was performed to define the risk factors of young patients (£45 years old) who presented to our department with an acute myocardial infarction (MI).
Methods: This case-control study was conducted over a 3-year period from March 2002 to April 2005 in a hospital admitting unselected patients with non-fatal acute myocardial infarction. Risk factor assessment was done in 72 subjects aged ≤45 years with a first acute myocardial infarct and in 143 age and sex-matched population-based controls.
Results: The mean (SD) age of the subjects was 40.11 (5.43) years, and 68 (84.5%) were male. In all, 70 subjects (32.55%) were current smokers: 43 (59.72%) in the case group and 27 (19.00%) in the control group (OR: 6.37, CI: 3.24-12.6, P=0.0001). Regular exercise had an independently protective effect on acute myocardial infarction in our young patients (OR: 0.24, 95% Cl: 0.08 to 0.70). Diabetes (OR: 7.66, CI: 2.2-29.15, p=0.0001) was associated with a higher risk of acute myocardial infarction in young adults, but the differences between hypertension (p=0.197), familial history of premature coronary artery disease (CAD) (p=0.25) and body mass index (BMI) (p=0.11) were not significant.
Conclusion: According to the results of this study, smoking is a leading risk factor for early acute myocardial infarction in our young patients in the Kurdistan province, which was modulated with primary prevention.
