Função ventricular esquerda e análise da deformação longitudinal miocárdica em pacientes com Doença de Chagas: série de casos e revisão sistemática da literatura

ABC., imagem cardiovasc; 37 (3), 2024
Introdução: Disfunção ventricular esquerda como preditor independente de mortalidade na doença de Chagas. A deformação longitudinal global (DLG) é uma modalidade ecocardiográfica emergente com possível valor incremental na detecção precoce de envolvimento cardíaco. Objetivo: Comparar a fun�...

The Role of the Immune System on the Cardiac Complications Observed in SARS-CoV-2

Abstract An acute respiratory syndrome caused by SARS-CoV2 was declared a pandemic by the World Health Organization. Current data in the world and in Brazil show that approximately 40% of patients who died have some type of cardiac comorbidity. There are also robust reports showing an increase in IL-6 / ...

Efectos clínicos de la corrección del valor de la fracción de expulsión del ventrículo izquierdo en pacientes con insuficiencia valvular mitral

Arch. cardiol. Méx; 90 (4), 2020
Resumen Introducción y objetivos: La insuficiencia valvular mitral provoca el vaciado simultáneo hacia la aorta y la aurícula izquierda durante la sístole ventricular, lo que produce una disminución del volumen hacia la circulación sistémica. En este estudio se busca obtener un dato preciso del p...

Prevalencia de disfunción diastólica de acuerdo con las guías diagnósticas de 2009 y 2016. Relación con la valoración hemodinámica no invasiva

Arch. cardiol. Méx; 90 (4), 2020
Resumen Objetivos: Evaluar la prevalencia de DD de acuerdo con los criterios de las guías del 2009 y 2016, y su relación con la distensibilidad arterial sistémica (DAS) y la resistencia vascular periférica (RVP). Material y métodos: Se analizó a 306 pacientes ≥ 40 años de edad, con fracci�...

Longitudinal Shortening of the Left Ventricle by Cine-CMR for Assessment of Diastolic Function in Patients with Aortic Valve Disease

Arq. bras. cardiol; 114 (2), 2020
Abstract Background: Diastolic dysfunction, commonly evaluated by echocardiography, is an important early finding in many cardiomyopathies. Cardiac magnetic resonance (CMR) often requires specialized sequences that extends the test time. Recently, feature-tracking imaging has been made available, but st...

Use of tissue doppler imaging for the early detection of myocardial dysfunction in patients with the indeterminate form of Chagas disease

Abstract INTRODUCTION: Chagas disease is one of the most common diseases in Latin America and heart involvement is the main cause of death. This study aimed to determine differences in tissue Doppler imaging (TDI) parameters in the assessment left and right ventricular function in patients with the ind...

The Use of Two-Dimensional Strain Measured by Speckle Tracking in the Identification of Incipient Ventricular Dysfunction in HIV-Infected Patients on Antiretroviral Therapy, Untreated HIV Patients and Healthy Controls

Arq. bras. cardiol; 113 (4), 2019
Abstract Background: Most cardiovascular abnormalities in patients infected with the human immunodeficiency virus (HIV) have been associated with myocardial damage directly caused by the virus. Some cases, however, may be associated with adverse effects from antiretroviral therapy (ART). New ventricular...

Strain Analysis of Left Ventricular Function in the Association of Hypertrophic Cardiomyopathy and Systemic Arterial Hypertension

Arq. bras. cardiol; 113 (4), 2019
Abstract Background: Hypertrophic cardiomyopathy (HCM) is the most common heart disease of genetic origin in the world population, with a prevalence of at least 1/500. The association with systemic arterial hypertension (SAH) is not uncommon, as it affects approximately 25% of the world population. Most...

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...
