Abstract/OtherAbstract:
BACKGROUND: Women with acute myocardial infarction have a higher hospital mortality rate than men. This difference has been ascribed to their older age, more frequent comorbidities, and less frequent use of revascularization. The aim of this study is to assess these factors in relation to excess mortality in women. METHODS AND RESULTS: All hospital admissions in France with a discharge diagnosis of acute myocardial infarction were extracted from the national payment database. Logistic regression on mortality was performed for age, comorbidities, and coronary interventions. Nonparametric microsimulation models estimated the percutaneous coronary intervention and mortality rates that women would experience if they were "treated like men." Data were analyzed from 74,389 patients hospitalized with acute myocardial infarction, 30.0% of whom were women. Women were older (75 versus 63 years of age; P<0.001) and had a higher rate of hospital mortality (14.8% versus 6.1%; P<0.0001) than men. Percutaneous coronary interventions were more frequent in men (7.4% versus 4.8%; 24.4% versus 14.2% with stent; P<0.001). Mortality adjusted for age and comorbidities was higher in women (P<0.001), with an excess adjusted absolute mortality of 1.95%. Simulation models related 0.46% of this excess to reduced use of procedures. Survival benefit related to percutaneous coronary intervention was lower among women. CONCLUSIONS: The difference in mortality rate between men and women with acute myocardial infarction is due largely to the different age structure of these populations. However, age-adjusted hospital mortality was higher for women and was associated with a lower rate of percutaneous coronary intervention. Simulations suggest that women would derive benefit from more frequent use of percutaneous coronary intervention, although these procedures appear less protective in women than in men.
