Promoting Autophagy Mitigates Stress‐Induced Remodeling in Patient iPSC‐CMs with the Phospholamban R9C Mutation

Advanced Science, EarlyView.
The Phospholamban (PLN) R9C mutation reduces SERCA2a binding, increasing calcium recycling and baseline contractility. However, the excess of free PLN promotes pentamer formation, limiting phosphorylation and blunting β‐adrenergic signaling. Under cardiac stress, enhanced functional demands overwhelm proteostasis in PLN R9C cells, leading to misfolded ...

Reprogramming the Myocardial Infarction Conductive Microenvironment with Superconductive Ionic Patch for Cardiac Function Repair

Advanced Science, EarlyView.
A super‐conductive ionic patch reprograms the post‐infarction microenvironment by enabling stable ionic migration and electrical signal transmission within damaged myocardium. The patch rapidly adheres to cardiac tissue, enhances conduction velocity, suppresses excitation‐contraction decoupling, and promotes structural and functional cardiac repair in ...

Novel pathways of heart failure with preserved ejection fraction [PDF]

, 2016
INTRODUCTION: Diastolic heart failure (HF) i.e., HF with preserved ejection fraction (HFpEF) accounts for ~50% of all clinical HF presentations; but unlike systolic HF i.e., HF with reduced ejection fraction (HFrEF), there are no evidenced based ...

Arterial stiffening is a crucial factor for left ventricular diastolic dysfunction in a community-based normotensive population

International Journal of Cardiology. Hypertension, 2020
Background: Left ventricular (LV) diastolic dysfunction is an important underlying hemodynamic mechanism for heart failure. Hypertension reportedly increases aortic stiffness with histological changes in the aorta assessed using aortic pulse wave ...

Diastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex [PDF]

, 2006
Background: Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic ...

The multi-modality cardiac imaging approach to the Athlete's heart: an expert consensus of the European Association of Cardiovascular Imaging [PDF]

, 2015
The term 'athlete's heart' refers to a clinical picture characterized by a slow heart rate and enlargement of the heart. A multi-modality imaging approach to the athlete's heart aims to differentiate physiological changes due to intensive training in the

Defining Diastolic Dysfunction [PDF]

Circulation, 2000
The human intellect has an almost irresistible urge to categorize and simplify. Thus, over the years, heart failure has been classified as forward or backward, right or left, compensated or decompensated. These distinctions, which were made primarily on the basis of data obtained from the history and physical examination, provided a conceptual ...

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism

Advanced Science, EarlyView.
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.

Left ventricular diastolic function and cardiotoxic chemotherapy

The Egyptian Heart Journal
Background Left ventricular ejection fraction falls when the myocardium has already lost a significant portion of its functional capacity. There are conflicting data on whether diastolic dysfunction precedes systolic dysfunction after cardiotoxic ...
