Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Advanced Echocardiography Assessment in the Management of Alcapa Syndrome: Case Report

Journal of Cardiovascular Development and Disease
Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare and potentially life-threatening condition affecting infants that requires immediate corrective surgery to restore blood flow to the myocardium.

P.49 Aortic Root Longitudinal Strain by Speckle-Tracking Echocardiography: Comparison with Cardiac Magnetic Resonance and Predictive Value in Marfan Syndrome Patients

Artery Research, 2020
Background: Low longitudinal strain of the ascending aorta (AAo) by cardiac magnetic resonance (CMR) predicts dilation and aortic events in Marfan syndrome (MFS) [1], possibly reflecting aortic stiffness [2].

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

Experimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

Predictors of exercise-induced pulmonary hypertension in patients with asymptomatic degenerative mitral regurgitation: mechanistic insights from 2D speckle-tracking echocardiography [PDF]

, 2017
Presence of exercise-induced pulmonary hypertension (EIPH) in asymptomatic degenerative mitral regurgitation (DMR) determines prognosis. This study aimed to elucidate the mechanism and predictors of EIPH in asymptomatic DMR.

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

The Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical

Speckle Tracking and Transthyretin Amyloid Cardiomyopathy

Arquivos Brasileiros de Cardiologia
Background: Amyloidosis is a disease caused by deposits of insoluble fibrils in extracellular spaces. The most common type of familial amyloidosis is mediated by mutation of transthyretin, especially Val30Met.

Acute intermittent hypercapnic hypoxia augments left ventricular contractility

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...
