The AMIS (Acute Myocardial Infarction in Switzerland) Plus prospective cohort study compared treatment and in-hospital outcomes between men and women with acute coronary syndrome (N = 26,452) admitted to Swiss hospitals between 1997 and 2007. The study reached several important conclusions: women had different baseline characteristics than men at admission, were treated with different drug regimens, and were significantly less likely to undergo percutaneous coronary intervention. After adjusting for these differences, researchers found no significant difference in the rates of in-hospital mortality between men and women, except for women aged 51 to 60 years, who were more likely to die in-hospital.
