[Female gender and acute myocardial infarction: what role does it play in the early and late prognosis].

The primary purpose of this study is to examine the influence of the female gender on the early and 1-year post-discharge prognosis after acute myocardial infarction (AMI). Moreover, the therapeutic approaches are compared between the two sexes during the early phase of AMI. We performed a retrospective cohort study of 341 patients, 219 men and 122 women, consecutively admitted to the coronary care unit with AMI. Among the baseline characteristics, the age greater than 70 years, the systemic hypertension and the diabetes mellitus are more represented in women; on the contrary cigarette smoking is prevalent in the male gender. The analysis of laboratory and clinical parameters does not show any statistic differences between the two sexes, except the ejection fraction and the coronary reperfusion. The first turns out to be lower in the females and the second one is more often observed in the males. As for the intra-hospital complications, the cardiogenic shock is prevalent in the female gender, the early mortality gets to 26% in women and 11% in men (p < 0.01). The late mortality during the follow-up does not present any difference between the two sexes. From our data, we conclude that transmural AMI, cardiogenic shock, ventricular fibrillation and 2-3 degree atrio-ventricular blocks are significantly bound to a higher early mortality in women. In them the atrial fibrillation is the only predictor of 1-year mortality. Finally, thrombolysis, beta-blockers and significantly aspirin and heparin (p < 0.05), are less used in the female patients, while diuretics and digoxin are more employed.(ABSTRACT TRUNCATED AT 250 WORDS)
