ABSTRACT

Objective: Due to devastating consequences of coronary artery disease (CAD) in young population, this study was designed to evaluate the prevalence of preventable risk factors and severity of atherosclerosis for Iranian young adults (≤45 years) diagnosed with premature CAD. Method: A cross sectional, descriptive study comprised 1093 consecutive patients (≤45 years), with a diagnosis of CAD, who underwent percutaneous intervention (PCI) or coronary bypass graft (CABG) from 2010 to 2012. Data on demographic features, cardiovascular risk factors, and angiographic findings were studied. Result: There were 1093 young patients (234 females, 859 males) with proven CAD; the mean age of 39 ± 3 years and the mean BMI were 28 ± 4.7 kg/m2. According to the treatment plan, patients were classified into two groups: PCI and CABG groups (n = 898,195 respectively). Obesity was the most prevalent risk factor (73.6%). In the risk factor assessment, it was noticed: 27% with diabetes mellitus, 37% with hypertension, 38% with family history, 39% with hyperlipidimia, and 54% smokers. Angiographic study revealed that 10 (1%) had left main coronary disease, 747 (68%) patients had single vessel disease, 181 (17%) had two-vessel disease and that 155 (14%) had three-vessel disease. The most common anatomical involvement was the anterior wall territory. Conclusion: Young CAD patients from Iran have different risk profile. Although atherosclerosis of the coronary arteries is less prominent in young patients, more often it is accompanied by decreased left ventricular function. There is a need for prevention plan to control obesity by targeting young adults in the population.
