Abstract 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 […]

Abstract Background: For patients with ST-segment elevation myocardial infarction (STEMI) that are suffering from subsequent coronary microvascular functional and structural obstruction (CMVO), no specific and definitive therapeutic approaches of attenuation have been proven valid in up-to-date large-scale tests, which highlights the urge to address its early recognition. Objectives: This study aimed to compare the performance of two clinical risk scores with an objective measurement of CMVO during percutaneous coronary intervention (PCI) with STEMI. Methods: The Index of Microcirculatory Resistance (IMR) […]

Abstract Background: Myocardial reperfusion is a fundamental part of the treatment for ST elevation myocardial infarction (STEMI) and is responsible for reducing morbidity and mortality in affected patients. However, reperfusion rates are usually lower and mortality rates higher in women compared to men. Objectives: To evaluate the prevalence of the use of reperfusion therapies among women and men with STEMI in hospitals where percutaneous coronary intervention (PCI) is available in the state of Sergipe. Methods: This is a cross-sectional study […]

Abstract Background Data on the management and prognosis of patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease are limited in Brazil, showing that the available revascularization strategies should be investigated Objective To assess the outcomes of complete revascularization versus treatment of the culprit artery only in patients with STEMI and multivessel disease. Methods A prospective cohort study was conducted at two medical centers in southern Brazil with a 1-year follow-up after the index procedure. The primary outcome was […]
