Exercise‐induced out‐of‐proportion increase in afterload and impaired right ventricular contractile reserve in HFpEF [PDF]

ESC Heart Failure
Aims The pathophysiology of heart failure with preserved ejection fraction (HFpEF) includes pulmonary vascular remodelling and right ventricular (RV) involvement. We sought to investigate the significance of non‐invasive cardiovascular magnetic resonance

First‐phase ejection fraction and ventricular‐arterial coupling across the lifespan: An in silico analysis [PDF]

Physiological Reports
First‐phase ejection fraction (EF1), the left ventricular ejection fraction (LVEF) up to maximal ventricular fiber shortening, has shown strong prognostic value in cardiovascular diseases, outperforming conventional LVEF, but remains uncharacterised in ...

Inhibition of TRIF-Dependent Inflammation Decelerates Afterload-Induced Myocardial Remodeling

Biomedicines, 2022
Pressure-overload-induced cardiac hypertrophy represents one cause of the development of heart failure. The aim of this study is to characterize the influence of the TIR-domain-containing adapter-inducing interferon-β (TRIF) during afterload-induced ...

Afterload reduction after non-invasive vagus nerve stimulation in acute heart failure

Frontiers in Human Neuroscience, 2023
IntroductionWhile central blood pressure (BP) has been recognized as a major indicator of left ventricular (LV) afterload, the reduction of central pressure decreases LV afterload and may prevent heart failure (HF) decompensation.

Right Ventricular Strain by Magnetic Resonance Feature Tracking Is Largely Afterload-Dependent and Does Not Reflect Contractility: Validation by Combined Volumetry and Invasive Pressure Tracings

Diagnostics, 2022
Cardiac magnetic resonance (CMR) is currently the gold standard for evaluating right ventricular (RV) function, which is critical in patients with pulmonary hypertension.

The acute influence of vasopressin on hemodynamic status and tissue oxygenation following the Norwood procedureCentral MessagePerspective

JTCVS Open, 2022
Objectives: Arginine vasopressin (AVP) is used to treat hypotension. Because AVP increases blood pressure by increasing systemic vascular resistance, it may have an adverse effect on tissue oxygenation following the Norwood procedure.

Myocardial Afterload Is a Key Biomechanical Regulator of Atrioventricular Myocyte Differentiation in Zebrafish

Journal of Cardiovascular Development and Disease, 2022
Heart valve development is governed by both genetic and biomechanical inputs. Prior work has demonstrated that oscillating shear stress associated with blood flow is required for normal atrioventricular (AV) valve development.

A Platform for Assessing Cellular Contractile Function Based on Magnetic Manipulation of Magnetoresponsive Hydrogel Films

Advanced Science, 2023
Despite significant advancements in in vitro cardiac modeling approaches, researchers still lack the capacity to obtain in vitro measurements of a key indicator of cardiac function: contractility, or stroke volume under specific loading conditions ...
