Abstract Background: Heart failure (HF) contributes to a high burden of hospitalization, and its form of presentation is associated with disease prognosis. Objectives: To describe the association of hemodynamic profile of acute HF patients at hospital admission, based on congestion (wet/dry) and perfusion (cold/warm), with mortality, hospital length of stay and risk of readmission. Methods: Cohort study, with patients participating in the “Best Practice in Cardiology” program, admitted for acute HF in Brazilian public hospitals between March 2016 and December […]

Abstract Background Residual venous congestion is a major contributor to readmission of patients with heart failure, and the venous excess ultrasound (VExUS) score is a potentially useful tool to evaluate systemic congestion. Objectives To investigate the association between VExUS score before hospital discharge among patients with heart failure and the risk of readmission due to acute decompensated heart failure (ADHF) within 90 days after discharge. Methods This prospective cohort study enrolled adults with signs and symptoms of ADHF, left ventricular […]

Abstract Background: Currently, excess ventilation has been grounded under the relationship between minute-ventilation/carbon dioxide output (). Alternatively, a new approach for ventilatory efficiency () has been published. Objective: Our main hypothesis is that comparatively low levels of between chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD) are attainable for a similar level of maximum and submaximal aerobic performance, conversely to long-established methods ( slope and intercept). Methods: Both groups performed lung function tests, echocardiography, and cardiopulmonary exercise testing. […]

ABOUT THESE STATISTICS The publication Cardiovascular Statistics – Brazil aims to provide an annual compilation of data and research on the epidemiology of CVDs in Brazil. The report integrates official statistics from the Brazilian Ministry of Health and other governmental entities alongside data from the GBD project, coordinated by the IHME at the University of Washington. Additionally, it incorporates data derived from various sources and scientific studies, including cohorts and registries, that relate to CVDs and their associated risk factors. […]

Abstract The objective of this case report was to present the progression of chemotherapy-induced cardiotoxicity in a patient with lymphoma, highlighting the importance of myocardial fluor-18-fluorodeoxyglucose (18F-FDG) uptake by positron emission tomography coupled with computed tomography (PET/CT). 43-year-old female patient with uterine lymphoma, who underwent hysterectomy followed by three chemotherapy regimens and radiotherapy. The patient had episodes of acute heart failure two years after chemotherapy. Echocardiogram revealed a reduction in left ventricular ejection fraction (LVEF). A retrospective analysis of 18F-FDG […]

Abstract Background Atrial fibrillation (AF) and heart failure (HF) frequently coexist, resulting in adverse outcomes. However, controversies remain regarding the efficacy of catheter ablation (CA) in AF patients with severe left ventricular dysfunction. Objectives The purpose of this study was to perform a meta-analysis of prospective randomized controlled trials to evaluate the efficacy of CA versus medical therapy (MT) in AF patients with left ventricular ejection fraction (LVEF) ≤45%. Methods We searched the literature for studies that compared CA to […]

Abstract Background While many risk models have been developed to predict prognosis in heart failure (HF), these models are rarely useful for the clinical practitioner as they include multiple variables that might be time-consuming to obtain, they are usually difficult to calculate, and they may suffer from statistical overfitting. Objectives To investigate whether a simpler model, namely the ACEF-MDRD score, could be used for predicting one-year mortality in HF patients. Methods 748 cases within the SELFIE-HF registry had complete data […]

Abstract Background The accuracy of the New York Heart Association (NYHA) classification to assess prognosis may be limited compared with objective cardiopulmonary exercise test (CPET) parameters in heart failure (HF). Objective To investigate the prognostic value of the NYHA classification in addition to Weber class. Methods Adult outpatients with HF undergoing CPET in a Brazilian tertiary care center were included. The physician-assigned NYHA class and the CPET-derived Weber class were stratified into “favorable” (NYHA I or II; Weber A or […]

Abstract Innovations in devices during the last decade contributed to enhanced diagnosis and treatment of patients with cardiac insufficiency. These tools progressively adapted to minimally invasive strategies with rapid, widespread use. The present article focuses on actual and future directions of device-related diagnosis and treatment of chronic heart failure.
