Abstract

Abstract: Aims: Data on how differences in risk factors, treatments, and outcomes differ between sexes in European countries are scarce. We aimed to study sex-related differences regarding baseline characteristics, in-hospital managements, and mortality of ST-elevation myocardial infarction (STEMI) patients in different European countries. Methods and results: Patients over the age of 18 with STEMI who were treated in hospitals in 2014–17 and registered in one of the national myocardial infarction registers in Estonia ( n = 5817), Hungary ( n = 30 787), Norway ( n = 33 054), and Sweden ( n = 49 533) were included. Cardiovascular risk factors, hospital treatment, and recommendation of discharge medications were obtained from the infarction registries. The primary outcome was mortality, in-hospital, after 30 days and after 1 year. Logistic and cox regression models were used to study the associations of sex and outcomes in the respective countries. Women were older than men (70–78 and 62–68 years, respectively) and received coronary angiography, percutaneous coronary intervention, left ventricular ejection fraction assessment, and evidence-based drugs to a lesser extent than men, in all countries. The crude mortality in-hospital rates (10.9–15.9 and 6.5–8.9%, respectively) at 30 days (13.0–19.9 and 8.2–10.9%, respectively) and at 1 year (20.3–28.1 and 12.4–17.2%, respectively) after hospitalization were higher in women than in men. In all countries, the sex-specific differences in mortality were attenuated in the adjusted analysis for 1-year mortality. Conclusion: Despite improved awareness of the sex-specific inequalities on managing patients with acute myocardial infarction in Europe, country-level data from this study show that women still receive less guideline-recommended management.
