Afterload increase challenge unmasks systolic abnormalities in heart failure with preserved ejection fraction

Int. j. cardiol; 380 (), 2023
BACKGROUND: Provocative maneuvers have the potential to overcome the low sensitivity of resting echocardiography and biomarkers in the detection of heart failure with preserved ejection fraction (HFpEF). We investigate the mechanical response of the left ventricle to an afterload challenge in patients wi...

Panorama do estado nutricional de pacientes adultos e idosos portadores de cardiopatia congênita: estudo congen
Overview of the nutritional status of adult and elderly patients with congenital heart disease: congen study

As cardiopatias congênitas (CC) são malformações no coração que levam a alterações estruturais ou circulatórias, comprometendo seu funcionamento. São responsáveis por 0.8–1.2% de todos os defeitos congênitos e têm uma prevalência de cerca de 5,8 por 1.000 pessoas. Um bom panorama nutricio...

Amiloidose Cardíaca: o que há de novo
Cardiac Amyloidosis: what’s new

Amiloidose se refere a um conjunto de doenças causadas pelo depósito de fragmentos anômalos de diferentes proteínas. O coração é um dos principais órgãos afetados, nas formas mais comuns de amiloidose, com os pacientes apresentando mau prognóstico e sobrevida curta, conforme o grau de acometime...

Machine learning-driven serum metabolomics: insights into the transition to early-stage heart failure with preserved ejection fraction

Circulation; 146 (Suppl 1), 2022
Introduction: Metabolomics has emerged as a powerful tool in providing readouts of early disease states before clinical manifestation. Here we used the predictive power of Unsupervised Hierarchical Clustering Analysis (UHCA) and Automated Machine Learning (AutoML) algorithms to identify serum metabolic p...

Anomalous pacemaker lead placement – a report of extrinsic compression of the left pulmonary artery

Arq. bras. cardiol; 119 (4 supl.1), 2022
INTRODUCTION: The Atrioventricular Septal Defect (AVSD) corresponds to 3% of congenital heart diseases, being associated with genetic syndromes and other congenital malformations. One of the anatomical alterations present in AVSD is the posterior displacement of the atrioventricular node, located between...

Viability assessment as a strategy to reduce long term events in left anterior descendent artery with chronic total occlusion

Arq. bras. cardiol; 119 (4 supl.1), 2022
INTRODUCTION: Late intervention of a chronic total occlusion (CTO) in stable patients is not routinely recommended by randomized trials. Previous studies have confirmed the negative effect of CTOs on prognosis. Purpose: To evaluate if a strategy of viability assessment (VA) to guide revascularization in ...

Epidemiological profile of patients with heart diseases with indications for palliative care

Arq. bras. cardiol; 119 (4 supl.1), 2022
INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of death in Western countries, with heart failure being the final pathway of heart disease. Despite this, few patients are referred for Palliative Approach (PA). There is no consensus about the indication or the right time to refer patients ...

2016 Left ventricular diastolic function guideline have better prognostic value than 2009 guideline in patients with acute coronary syndrome

Arq. bras. cardiol; 119 (4 supl.1), 2022
BACKGROUND: Cardiovascular disease is the leading cause of death in Brazil and worldwide. In the context of diastolic dysfunction, echocardiography is the best non-invasive diagnostic method. However, the comparison of the two main guidelines for evaluate left ventricular diastolic function in acute coro...

Independent assessment of the atrial fibrillation - hypertrophic cardiomyopathy score in a brazilian cohort

Arq. bras. cardiol; 119 (4 supl.1), 2022
BACKGROUND: Atrial fibrillation (AF) is a common arrhythmia in hypertrophic cardiomyopathy (HCM), frequently related to adverse outcomes. The AF-HCM point-score is a recently validated predictive model for the assessment of AF risk. OBJECTIVES: We sought to independently evaluate the novel AF-HCM score i...

Long covid as a new etiology for heart transplantation: a case series

Arq. bras. cardiol; 119 (4 supl.1), 2022
BACKGROUND: Long COVID is a condition characterized by long-term consequences persisting or appearing after the typical convalescence period of COVID-19. It may last several months but the duration is still matter of observation. The symptoms and the clinical manifestations are clinically heterogeneous i...
