          Abstract

          Sixty patients less than 35 years with a first Q wave acute myocardial infarction were prospectively studied to evaluate their features, risk factors and evidence of any viral infection. Typical chest pain was present in 98.3% with Q waves and ST segment elevation in all. None had hypotension or cardiogenic shock. Smoking was the most common risk factor (81.7%). Mean total cholesterol was 5.74 (+/-1.42) mmol/l. History of a viral illness was present in 28.3%, severe emotional stress in 21.7% and exhausting physical activity in 18.3%. Mean left ventricular diastolic and end systolic volumes were increased (90.11+/-22.5 ml/m2) and (46.62+/-20.46 ml/m2), respectively. The ejection fraction was depressed (49.71+/-1.6%). Triple vessel disease was seen only in 6.8 and 26.7% had insignificant or no coronary artery disease. Left anterior descending artery was most frequently involved (66%). None had left main involvement. Coronary ectasia was present in 11.7%, intracoronary thrombus in 28.3% and 40% had collaterals. Patients with no significant disease had no diabetes, a smaller number had a raised total cholesterol or smoked and had a lower ejection fraction. Patients from the Indian subcontinent who had fewer conventional risk factors, had more severe disease than those from the Arab world suggesting that other etiological factors need investigation.
