Sex Differences in Outcomes of ST Elevation Myocardial Infarction Patients Submitted to Primary Percutaneous Coronary Intervention.

Background: Several studies have shown that women are usually undertreated and have worse outcomes after ST-segment elevation myocardial infarction (STEMI), hence the need to investigate questions related to sex in Brazil to better deal with the problem.

Objective: To determine whether female sex is still associated with adverse events in a contemporary cohort of patients with STEMI undergoing primary percutaneous coronary intervention (pPCI).

Methods: This was a prospective cohort study of STEMI patients submitted to pPCI in a tertiary university hospital between March 2011 and December 2021.
