Abstract Background: Acute myocardial infarction (AMI) is defined as the death of cardiomyocytes due to prolonged ischemia, caused by thrombosis and / or vasospasm on an atherosclerotic plaque. Objective: To determine the incidence of patients with myocardial infarction undergoing primary angioplasty; characterize the anthropometric variables and identify the risk factors in this population. Methods: This was a cross-sectional, observational, retrospective study in which we collected secondary data from medical records of a hospital in a city in the state of […]

Abstract Background: To reduce mortality of acute myocardial infarction, medical care must be provided within the first hours of the event. Methods: The study was a retrospective analysis of the medical records of 112 consecutive patients diagnosed with acute myocardial infarction by coronary angiography. We identified the place of the first medical contact and calculated the time between admission to this place and admission to the referral hospital, as well as the time until coronary angiography, with or without percutaneous […]

Abstract Background: Primary percutaneous coronary intervention is the preferred treatment in ST-elevation myocardial infarction. At night period, the delay until performing primary percutaneous coronary intervention may be determinant to prognosis worsening. Objective: To analyze the results of primary percutaneous coronary intervention performed at day and night periods. Methods: Cohort study that included patients admitted with ST-elevation myocardial infarction who underwent primary percutaneous coronary intervention from December 2013 until December 2016 in a ST-elevation myocardial infarction reference hospital of a metropolitan […]

Abstract Background: The Brazilian Unified Health System (SUS) was created to ensure universal, integral and equitable access to quality healthcare to Brazilians. However, studies scrutinizing the quality of the healthcare provided by the SUS are scarce. This is especially critical for patients with ST-elevation myocardial infarction (STEMI), who depend on healthcare system responsiveness and timely reperfusion to achieve better outcomes. Objective: To describe the methodology of the VICTIM Registry aimed at characterizing and comparing the access to effective therapies and […]

Abstract Background: Cardiovascular diseases are the leading cause of death in Brazil. Biochemical markers have diagnostic and prognostic importance in acute coronary syndromes (ACSs), with troponin as the preferred biomarker. Studies have already demonstrated a positive relationship between increased levels of high-sensitivity troponin (hsTn) and prognosis. However, few studies have correlated hsTn levels with the complexity of coronary lesions. Objectives: To compare hsTn levels with the complexity of coronary lesions according to the SYNTAX score, and to correlate the levels […]

Abstract Background: Approximately 20 to 40% of patients with heart failure do not respond to cardiac resynchronization therapy (CRT). To improve patient selection, phase analysis by myocardial perfusion scintigraphy (GSPECT) was developed. Objectives: To evaluate the clinical and scintigraphic response of patients with heart failure (HF) submitted to CRT using GSPECT. Method: This was an interventional study that included consecutive patients assessed by GSPECT four weeks prior to CRT implantation and six months after it for comparison. These patients also […]

Abstract Background: Acute myocardial infarction is one of the main causes of morbidity and mortality in the world, and one of the factors with the greatest prognostic impact is early specialist care, but there are still many factors that delay patient’s arrival at the hospital. Objective: To correlate social, educational, cognitive and clinical factors with time to hospital arrival after the onset of acute myocardial infarction’s first symptoms. Methods: Time interval to search for medical care was measured by patient’s […]

Abstract Background: Physical activity reduces the risk of coronary heart disease, one of the leading causes of death in the world. Objectives: This study intends to correlate physical activity and clinical variables of the patients hospitalized in public hospitals of Santa Catarina after the first acute myocardial infarction. Methods: The selected patients answered a questionnaire on different clinical variables. Physical activity was measured using the Baecke’s questionnaire. Data were tabulated and analyzed using the SPSS 13.0 for Windows software. Normality […]

Abstract Background: Different scores based on anatomical and/or clinical features have been developed for risk stratification of patients undergoing percutaneous coronary intervention (PCI). Studies comparing the ability of these different models in predicting major adverse cardiac and cerebrovascular events (MACCE) in patients submitted to primary PCI are limited. Objectives: The aim of this study was to compare the ability of the scores SYNTAX (SS), Clinical SYNTAX (CSS), ACEF, and modified ACEF (ACEFMod) to predict MACCE in patients with ST-elevation myocardial […]

Introduction Cardiac events are rarely associated with ophidian accidents, especially those involving snakes of the Elapidae family. We report on a snake bite victim who, within a few hours after the accident, developed myocardial infarction in the inferior wall with good clinical evolution. […]
