[Clinical profile, coronary angiography findings and early outcome in young patients with acute myocardial infarction in the thrombolytic era].
OBJECTIVE
To assess the clinical, angiographic and early follow-up findings of young patients suffering an acute myocardial infarction, in comparison with older patients with infarction, in the thrombolytic era.


METHODS
A retrospective analysis of the medical records of 46 patients < 40 years-old (group I) at the time of an acute myocardial infarction was compared with that of 46 older patients, randomly selected, presenting with this syndrome between february, 1991 and february, 1996 (group II). In both groups a comparison was conducted regarding the proportions of gender, risk factors, type of infarction (Q vs non-Q), left ventricular function, coronary anatomy and early mortality (1 month). The medical treatment was comparable for both groups, including the utilization of thrombolytics.


RESULTS
The groups were discriminated only by: higher prevalence of smoking, of angiographically normal coronary arteries, and of non-critical (< 75% reduction of luminal diameter) coronary stenosis in group I; in the older group a higher proportion of patients had multivessel disease. Although not reaching statistical significance, a trend was observed to a more benign early course of the infarction in the patients less than < 40 years-old.


CONCLUSIONS
The present findings are similar to those described in the pre-thrombolytic era, for young patients suffering an acute myocardial infarction.
