Cine angiographic findings in young Iraqi men with first acute myocardial infarction.

Among 100 consecutive Iraqi men aged 40 years or less with first acute myocardial infarction, coronary angiography performed 8-12 weeks later showed single-vessel coronary artery disease in 64, multivessel disease in 26, and normal coronary arteries in ten patients. Most patients (90%) had one or more coronary risk factors. The left anterior descending artery was involved in 66 patients, the right coronary artery in 38, and the circumflex artery in 29. Total occlusion was seen in 37 patients and severe (greater than or equal to 90%) stenosis in 14 patients. Severe wall motion abnormality (aneurysm formation) on left ventriculography was found in 33 patients. Thus, in developing countries as elsewhere, one-vessel coronary artery disease remains the most common angiographic finding in young men with first acute myocardial infarction.
