Comparison between young males and females with acute myocardial infarction.
OBJECTIVE
To assess the differences between young males and females after acute myocardial infarction.


METHODS
We retrospectively studied 236 patients (54 females and 182 males) after acute myocardial infarction and during hospital stay assessed the following parameters: risk factors; the treatment used; the pattern of coronary artery obstruction; left ventricular ejection fraction; complications; and, using a logistic regression model, the factors related to the occurrence of reinfarction and death.


RESULTS
No significant difference was observed between the sexes in risk factors, pattern of coronary artery obstruction, and left ventricular function. The time interval between symptom onset and treatment was longer in females (p=0.03), who underwent thrombolysis (p=0.01) and angioplasty (p=0.03) less frequently than males did, but not myocardial revascularization. Female sex (OR = 5.98) and diabetes (OR = 14.52) were independent factors related to the occurrence of reinfarction and death.


CONCLUSIONS
Young males and females after acute myocardial infarction did not differ in coronary risk factors, and clinical and hemodynamic characteristics. Females had their treatment started later, and they underwent chemical thrombolysis and angioplasty less frequently than males did. Female sex and diabetes were related to the occurrence of reinfarction and death.
