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...

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 ...

Functional magnetic resonance imaging in the evaluation of the elastic properties of ascending aortic aneurysm

Abstract Objective: To evaluate the aortic wall elasticity using the maximal rate of systolic distension (MRSD) and maximal rate of diastolic recoil (MRDR) and their correlation with the aortic size index (ASI). Methods: Forty-eight patients with thoracic aortic aneurysm were enrolled in this study. A ...

The effect of levothyroxine treatment on left ventricular function in subclinical hypothyroidism

ABSTRACT Objective: Treatment of subclinical hypothyroidism (ScH), especially the mild form of ScH, is controversial because thyroid hormones influence cardiac function. We investigate left ventricular systolic and diastolic function in ScH and evaluate the effect of 5-month levothyroxine treatment. Su...

Impact of a High-Intensity Training on Ventricular Function in Rats After Acute Myocardial Infarction

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Physical exercise should be part of the treatment of post-acute myocardial infarction (AMI) patients. Objective: To evaluate the effects of two training prescription models (continuous x interval) and its impact on ventricular function in rats after AMI with normal ventricular func...

Echocardiographic Assessment of Ventricular Function in Young Patients with Asthma

Arq. bras. cardiol; 110 (3), 2018
Abstract Background: Despite significant advances in understanding the pathophysiology and management of asthma, some of systemic effects of asthma are still not well defined. Objectives: To compare heart function, baseline physical activity level, and functional exercise capacity in young patients w...

Three-Dimensional Volumetric Assessment of Diastolic Function by Cardiac Magnetic Resonance Imaging: The Multi-Ethnic Study of Atherosclerosis (MESA)

Arq. bras. cardiol; 108 (6), 2017
Abstract Background: Cardiac Magnetic Resonance is in need of a simple and robust method for diastolic function assessment that can be done with routine protocol sequences. Objective: To develop and validate a three-dimensional (3D) model-based volumetric assessment of diastolic function using cardiac ...

Kinetics of Hypotension during 50 Sessions of Resistance and Aerobic Training in Hypertensive Patients: a Randomized Clinical Trial

Arq. bras. cardiol; 108 (4), 2017
Abstract Background: Resistance and aerobic training are recommended as an adjunctive treatment for hypertension. However, the number of sessions required until the hypotensive effect of the exercise has stabilized has not been clearly established. Objective: To establish the adaptive kinetics of the b...
