    Abstract:
    The number of women who become ill and die from acute myocardial infarction (AMI) increases steadily with age. It is not yet clearly defined whether and why women suffer from a higher in-hospital mortality rate after AMI. In this study we evaluated the importance of the female sex as a risk factor for in-hospital mortality in elderly patients suffering from AMI. A retrospective study was performed in 724 patients (429 males, 295 females) aged > or = 65 years (mean age 74.9 +/- 6.3 years) consecutively admitted to San Giovanni Battista Hospital in Turin during the period 1988-1991 with validated primary discharge diagnosis of AMI. In-hospital mortality was significantly higher in females (34.6%) compared to males (25.6%, p > 0.01). After multivariate analysis female sex was not independent predictive for in-hospital death. Multivariate analysis was therefore repeated in the various sections of the history of AMI (anamnestic variables, including age and sex: physical signs on admission, ECG findings, laboratory tests, clinical progress, including complications and treatment) in order to identify the factors responsible for the higher mortality rate in women. These were found to be low hemoglobin values (< 12 g/dl) on admission, development of cardiac failure disorders and rhythm disturbances during hospitalization, and differences in therapeutic procedures. In spite of the absence of an independent unfavourable effect of female sex, elderly women with AMI have a higher in-hospital mortality rate. A more precarious state of health on admission, a peculiar susceptibility to severe complications during hospital-stay and differences in therapeutic procedures appear to be the factors responsible for this increased mortality rate in women.
