Resection of the atrial appendages and its impact in the natriuretic homeostasis: development and validation of an animal model in an academic medical center

Rev. invest. clín; 72 (2), 2020
ABSTRACT Background: The left atrial appendage (LAAp) resection is an effective treatment approach to reduce the risk of thromboembolism in patients with atrial fibrillation. Objective: To study was to study the impact of removing atrial appendages in the production of natriuretic peptides (NPs) in con...

Beta-Blocker Type Effect on Substrate Oxidation during HIIE in Heart Failure Patients: Pilot Data

Arq. bras. cardiol; 112 (3), 2019
Abstract The effect of third and second-generation type of beta-blocker on substrate oxidation especially during high-intensity exercises are scarce. The objective of the study is to explore differences of beta-blocker regimens (vasodilating vs. non-vasodilating beta-blockers) for substrate oxidation dur...

A practical approach to assess leg muscle oxygenation during ramp-incremental cycle ergometry in heart failure

Braz. j. med. biol. res; 50 (12), 2017
Heart failure is characterized by the inability of the cardiovascular system to maintain oxygen (O2) delivery (i.e., muscle blood flow in non-hypoxemic patients) to meet O2 demands. The resulting increase in fractional O2 extraction can be non-invasively tracked by deoxygenated hemoglobin concentration (...

Valoración de la composición corporal y su influencia pronóstica en insuficiencia cardiaca crónica. Más allá de la «paradoja de la obesidad»

Arch. cardiol. Méx; 86 (4), 2016
Resumen Objetivo Se desconoce la influencia pronóstica que la composición corporal guarda en la relación inversa de la mortalidad con el sobrepeso y la obesidad en pacientes con insuficiencia cardiaca. Método Se evaluó a 234 pacientes ambulatorios con insuficiencia cardiaca. Se determinaron el ín...
