Presystolic Wave is Associated with Subclinical Left Ventricular Dysfunction Assessed by Myocardial Performance Index in Type 2 Diabetes Mellitus

Arq. bras. cardiol; 113 (2), 2019
Abstract Background: Myocardial performance index (MPI), demonstrates both systolic and diastolic functions of the left ventricle. Presystolic wave (PSW) is frequently detected on Doppler examination of the left ventricular outflow tract and possible mechanism of PSW is impaired LV compliance and left v...

Cardiac function and intracellular Ca2+ handling proteins are not impaired by high-saturated-fat diet-induced obesity

Braz. j. med. biol. res; 52 (6), 2019
Obesity is often associated with changes in cardiac function; however, the mechanisms responsible for functional abnormalities have not yet been fully clarified. Considering the lack of information regarding high-saturated-fat diet-induced obesity, heart function, and the proteins involved in myocardial ...

Dysfunctional breathing: what do we know?

J. bras. pneumol; 45 (1), 2019
ABSTRACT Dysfunctional breathing (DB) is a respiratory condition characterized by irregular breathing patterns that occur either in the absence of concurrent diseases or secondary to cardiopulmonary diseases. Although the primary symptom is often dyspnea or "air hunger", DB is also associated with nonres...

Interacciones cardiopulmonares: de la fisiología a la clínica

Rev. chil. pediatr; 89 (5), 2018
Resumen: Las Interacciones Cardiopulmonares (ICP) corresponden al conjunto de interrelaciones entre el sis tema respiratorio y el cardiovascular, durante el ciclo respiratorio y cardíaco. Estas interacciones varían dependiendo de si el paciente se encuentra en ventilación espontánea o mecánica, afec...

Is There any Relationship Between Myocardial Repolarization Parameters and the Frequency of Ventricular Premature Contractions?

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: Ventricular premature contractions (VPCs) may trigger lethal ventricular arrhythmias in patients with structural heart disease. However, this role of VPCs in healthy people remains controversial once that not enough clinical trials are available. Recently, some myocardial repolariza...

Subclinical Anthracycline-Induced Cardiotoxicity in the Long - Term Follow-Up of Lymphoma Survivors: A Multi-Layer Speckle Tracking Analysis

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Anthracycline generates progressive left ventricular dysfunction associated with a poor prognosis. Objectives: The purpose of this study was to evaluate whether layer-specific strain analysis could assess the subclinical left ventricular dysfunction after exposure to anthracyclin...

Cardiac dysfunction and ferritin as early markers of severity in pediatric sepsis

J. pediatr. (Rio J.); 93 (3), 2017
Abstract Objective: The aim of this study was to verify the association of echocardiogram, ferritin, C-reactive protein, and leukocyte count with unfavorable outcomes in pediatric sepsis. Methods: A prospective cohort study was carried out from March to December 2014, with pediatric critical care patie...

Left Atrial Deformation Analysis in Patients with Corrected Tetralogy of Fallot by 3D Speckle-Tracking Echocardiography (from the MAGYAR-Path Study)

Arq. bras. cardiol; 108 (2), 2017
Abstract Background: Three-dimensional (3D) echocardiography coupled with speckle-tracking echocardiographic (STE) capability is a novel methodology which has been demontrated to be useful for the assessment of left atrial (LA) volumes and functional properties. There is increased scientific interest on...

Estado atual do tratamento dos defeitos do septo atrial

A comunicação interatrial tipo ostium secundum (CIA OS) é uma cardiopatia congênita relativamente frequente, que causa repercussão hemodinâmica para o ventrículo direito, com sobrecarga volumétrica e dilatação da câmara. A maioria dos pacientes é assintomática, porém sintomas podem aparecer...
