INTRODUCTION: Brain natriuretic peptide (BNP) is a highly sensitive and specific biomarker for the extent of myocardial infarction that is strongly related to short- and long-term prognosis in patients with acute coronary syndromes. OBJECTIVE: To assess the prognostic value of BNP levels in a Portuguese cohort of ST-elevation myocardial infarction (STEMI) patients. METHODS: We performed a retrospective analysis of patients admitted with STEMI included in the Portuguese Registry of Acute Coronary Syndromes (ProACS) between 2010 and 2019...

Acute severe mitral regurgitation (MR) because of secondary left ventricular impaired regional contractility can present with severe acute heart failure, associated with a high risk for rapid decompensation, pulmonary edema and cardiogenic shock. Frequently, in these highly unstable patients, surgical risk can be prohibitive. Evidence for percutaneous repair of acute MR is scarce, but a few case series show that this approach could be safe and effective for bailing out hemodynamically unstable patients. We report a case of an 84-year-old man with acute ischemic severe MR post-acute myocardial infarction (MI), who remained hemodynamically unstable despite coronary revascularization, positive pressure non-invasive ventilation, vasodilator therapy and intra-aortic balloon pump (IABP) support...

INTRODUCTION AND OBJECTIVES: The electrocardiogram continues to be essential in the diagnosis of acute myocardial infarction, and a useful tool in arrhythmic risk stratification. We aimed to determine which electrocardiographic variables can successfully predict the occurrence of ventricular arrhythmias (VA) in patients following ST-segment elevation myocardial infarction (STEMI). METHODS: We performed an observational study including 667 patients with STEMI admitted to the University Hospital in Sancti Spíritus, Cuba...

INTRODUCTION AND OBJECTIVES: Thrombosis is involved in the onset and progression of ST-segment elevation myocardial infarction (STEMI). The aim of this study was to explore the expression level of serum- and glucocorticoid-inducible kinase 1 (SGK1) in intracoronary thrombus and the relationship between them. METHODS: We identified 30 patients who received treatment in the Affiliated Hospital of Hangzhou Normal University between May 2018 to May 2020 and who underwent thrombus aspiration and percutaneous coronary intervention for ST-segment-elevation myocardial infarction...

INTRODUCTION: The triglyceride-glucose (TyG) index is considered a new marker of insulin resistance, and is associated with the development of cardiovascular diseases. OBJECTIVE: To evaluate the capability of TyG index to predict in-hospital -mortality in patients with acute ST-elevation myocardial infarction. METHODS: Multicenter cohort study that enrolled 1123 patients included in the Cuban Registry of Acute Myocardial Infarction between January 2018 and June 2021...

INTRODUCTION AND OBJECTIVES: Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction (AMI). We sought to compare the results on in-hospital mortality and 30-day readmission rates among patients with AMI-SCAD vs AMI due to other causes (AMI-non-SCAD). METHODS: Risk-standardized in-hospital mortality (rIMR) and risk-standardized 30-day readmission ratios (rRAR) were calculated using the minimum dataset of the Spanish National Health System (2016-2019)...

OBJECTIVE: The purpose was to compare the outcomes of patients with ST-elevation myocardial infarction and multivessel coronary artery disease undergoing one-time multivessel revascularization (OTMVR) versus in-hospital staged complete revascularization with percutaneous coronary intervention. METHODS: This was a single-center, retrospective, observational, and cohort study, including data from January 2013 to April 2019. A total of 634 patients were included in the study...

BACKGROUND: Reduction of LDL-cholesterol (LDL-c) levels is the cornerstone in risk reduction, but many high-risk patients are not achieving the recommended lipid goals, even in high-income countries. OBJECTIVE: To evaluate whether patients seen in the city of Curitiba public health system are reaching LDL-c goals after an acute myocardial infarction (AMI). METHODS: This retrospective cohort explored the data of patients admitted with AMI between 2008 and 2015 in public hospitals from the city of Curitiba...

BACKGROUND: Contemporary diagnosis of ACS and risk stratification are essential for appropriate management and reduction of mortality and recurrent ischemic events, in the acute phase of disease and after hospitalization. The Universal Definition of Myocardial Infarction recommends the detection of troponin levels above the 99th percentile. OBJECTIVES: To evaluate the occurrence of early death and acute myocardial infarction (AMI) in patients without elevation of troponin (<0...

BACKGROUND: It has recently been demonstrated that the application of high-energy ultrasound and microbubbles, in a technique known as sonothrombolysis, dissolves intravascular thrombi and increases the angiographic recanalization rate in patients with ST-segment-elevation myocardial infarction (STEMI). OBJECTIVE: To evaluate the effects of sonothrombolysis on left ventricular wall motion and myocardial perfusion in patients with STEMI, using real-time myocardial perfusion echocardiography (RTMPE)...

BACKGROUND: Acute myocarditis frequently mimics an acute myocardial infarction, and its diagnosis is a clinical challenge. AIM: To describe the characteristics of cardiac magnetic resonance imaging in patients with acute myocarditis hospitalized with a diagnosis of ST-segment elevation myocardial infarction. PATIENTS AND METHODS: Twenty-four patients aged 33 ± 11 years (21 men) with a definitive diagnosis of acute myocarditis hospitalized with a presumptive diagnosis of ST-segment elevation myocardial infarction, in whom a coronary angiogram excluded significant atherosclerotic coronary lesions, were included...

BACKGROUND: About 40% of patients with ST-segment elevation myocardial infarction (STEMI) in Brazil do not receive reperfusion therapy. OBJECTIVE: The use of a telemedicine network based on WhatsApp® could increase the percentage of patients receiving reperfusion therapy. METHODS: A cross-sectional study analyzed outcomes before and after the organization of a telemedicine network to send the electrocardiogram via WhatsApp® of patients suspected of STEMI from 25 municipalities that are members of the Regional Health Department of Ribeirão Preto (DRS-XIII) to a tertiary hospital, which could authorize immediate patient transfer using the same system...

INTRODUCTION AND OBJECTIVES: To analyze whether admission on weekends or public holidays (WHA) influences the management (performance of angioplasty, percutaneous coronary intervention [PCI]) and outcomes (in-hospital mortality) of patients hospitalized for acute coronary syndrome in the Spanish National Health System compared with admission on weekdays. METHODS: Retrospective observational study of patients admitted for ST-segment elevation myocardial infarction (STEMI) or for non-ST-segment elevation acute coronary syndrome (NSTEACS) in hospitals of the Spanish National Health system from 2003 to 2018...

INTRODUCTION AND OBJECTIVES: To study the impact of injecting intracoronary eptifibatide plus vasodilators via thrombus aspiration catheter vs thrombus aspiration alone in reducing the risk of no-reflow in acute ST-elevation myocardial infarction (STEMI) with diabetes and high thrombus burden. METHODS: The study involved 413 diabetic STEMI patients with high thrombus burden, randomized to intracoronary injection (distal to the occlusion) of eptifibatide, nitroglycerin and verapamil after thrombus aspiration and prior to balloon inflation (n=206) vs thrombus aspiration alone (n=207)...

INTRODUCTION AND OBJECTIVES: As short-term mortality continues to decrease after myocardial infarction (MI), secondary prevention strategies attain increasing relevance. This study aimed at assessing the control of cardiovascular (CV) risk factors, including dyslipidemia, hypertension and diabetes, in a contemporary cohort of MI survivors who completed an exercise-based cardiac rehabilitation (EBCR) program. METHODS: Observational, retrospective cohort study including patients admitted to a tertiary center with acute MI between November 2012 and April 2017, who completed a phase II EBCR program after discharge...

Although ST-segment elevation myocardial infarction (STEMI) mortality decreased with the progress of reperfusion, the incidence of hospital complications has not changed. We aimed to describe the incidence of STEMI complications in the coronary unit, the timing of their occurrence and to identify their predisposing and protective factors. This is a prospective analysis of all consecutive patients with STEMI admitted to a coronary care unit of a third level reference hospital from September 2017 to March 2020...
