Risk factors and angiographic profile of coronary artery disease in young.

ABSTRACT

A total of 124 patients of ischaemic heart disease under 40 years of age (96 with myocardial infarction and 28 with angina) were studied for risk factors of coronary artery disease. Electrocardiogram, treadmill test, lipid profile and coronary arteriography were done in all cases. Smoking (56.4%) and hyperlipidaemia (30.6%) emerged as the major risk factors. Further stratification of lipid profile revealed that predictive value of hypercholesterolaemia could be enhanced by considering the different ratios of lipoproteins and indices of atherogenicity. Coronary arteriography revealed a preponderance of single vessel disease (48.4%)-left anterior descending being most commonly involved (71.8%). Increase in low density lipoprotein fraction was related to multivessel involvement.
