A relative paucity of information concerns the natural history, clinical features and coronary anatomy in young patients with acute myocardial infarction. In particular, there is a dearth of data relating to sex differences in young patients. The objective was to evaluate whether or not there are correlations between the clinical characteristics and the extent and localization of coronary artery lesions in young men compared with young women. The study population consisted of 1646 young patients (87% men, 13% women; mean age 39±5 years) with a first acute myocardial infarction admitted to one of the 125 coronary care units of Italy in a period of 3 years. Clinical data were collected. All patients underwent coronary angiography during hospitalization. Smoking, hypercholesterolemia and obesity were significantly more prevalent in men than in women; physical inactivity was significantly more prevalent among women. Hemodynamically significant coronary stenosis occurred in 82% of patients and were more frequent in men than in women (P<0.05). Women more frequently had single-vessel disease and no coronary lesions at all (58 vs. 47% and 24 vs. 9% women vs. men respectively, both P<0.05). Men more frequently had multivessel disease (38 vs. 13%, P<0.05). Significant stenosis mainly affected the left anterior descending artery (52%) with no gender-related difference; men more likely had lesions of the left circumflex or right coronary artery (P<0.05). In conclusion, young patients with a first acute myocardial infarction risk factors profile and extent of coronary artery lesions were significantly different between sexes.
