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...

Utilidad de la ecocardiografía transtorácica focalizada en emergencias hemodinámicas intraoperatorias

Rev. chil. anest; 49 (4), 2020
INTRODUCTION: Echocardiography represents one of the most important advances in the monitoring of critical patients. Initially available only in cardiovascular surgery, currently, there is transesophageal echocardiography (TEE) and transthoracic echocardiography (ETT) in non-cardiac surgery, for anesthes...

Risk of Obstructive Sleep Apnea and Echocardiographic Parameters

Arq. bras. cardiol; 113 (6), 2019
Abstract Background: Obstructive sleep apnea (OSA) is a chronic progressive disorder with high mortality and morbidity rate, associated with cardiovascular diseases (CVD), especially heart failure (HF). The pathophysiological changes related to OSA can directly affect the diastolic function of the left ...

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...

Left ventricular assessment in patients with mucopolysaccharidosis using conventional echocardiography and myocardial deformation by two-dimensional speckle-tracking method

J. pediatr. (Rio J.); 95 (4), 2019
Abstract Objective: Mucopolysaccharidosis is a rare genetic disease characterized by the intralysosomal deposition of glycosaminoglycans. Cardiovascular impairment is a common feature. Cardiac signs and symptoms are underestimated due to the disease involvement in other organs. Enzyme replacement therap...

Early Detection and Monitoring of Cancer Chemotherapy-Related Left Ventricular Dysfunction by Imaging Methods

Arq. bras. cardiol; 112 (3), 2019

Disease activity is associated with LV dysfunction in rheumatoid arthritis patients without clinical cardiovascular disease

Adv Rheumatol; 59 (), 2019
Abstract Objectives: The cross-sectional study aimed to assess left ventricular systolic function using global longitudinal strain (GLS) by speckle-tracking echocardiography (STE) and arterial stiffness using cardio-ankle vascular index (CAVI) in Thai adults with rheumatoid arthritis (RA) and no clinica...

Echocardiographic Study of the Coronary Sinus in the Indeterminate Form of Chagas Disease

Abstract INTRODUCTION: We investigated the occurrence of coronary sinus abnormalities in the indeterminate form of Chagas disease (CD). METHODS: Differences between the maximum and minimum diameters of the coronary sinus (∆%) on echocardiography were evaluated in individuals with the indetermin...
