Background: In the evolution of myocardial infarction the gender could be a prognostic factor. Women may have bigger mortality and complication rates.
Aim: To study if there are differences in the evolution of myocardial infarction between men and women.
Methods: We have a databases and information of risk factors, clinical evolution, treatment and complications of 3500 patients with myocardial infarction in 45 Chilean hospitals. These databases are part of the GEMI (Infarction Multicenter Studies Group).
Results: A 26 % of analyzed patients were female. Mortality rates between males and females were 11.8 and 20.2% respectively. Women present more risk factors like smoking, diabetes, obesity and hypertension. Women were subjected to less invasive procedures than men.
Discussion: Female sex is an independent risk factor for acute myocardial infarction mortality. Diabetes is more frequently in women and the older age of female patients might be one of the causes associated with a more negative prognostic.
Conclusions: Future studies should clarify which risk factors in female patients are more important like smoking, dyslipidemia or hypertension.
