Cyclic Mechanical Loading of Cardiomyocytes via Pressure‐Driven Non‐Planar Membrane Deformation in a Bioreactor System

Advanced Science, EarlyView.
In this research article, Mansoor and coworkers present a novel device that applies controlled mechanical stimuli to cardiomyocytes using pressure‐driven membrane deformation. By exposing cells to physiologically and pathologically relevant loading conditions, the platform reproduces distinct structural, functional and molecular responses associated ...

Role of cardiac MRI in nonischemic cardiomyopathies

Indian Heart Journal, 2016
Cardiac magnetic resonance (CMR) with its higher spatial resolution is considered the gold standard for evaluating ventricular mass, volumes, and ejection fraction. CMR can be used for accurate diagnosis of several conditions, especially cardiomyopathies.

Incidence of long-term cardiotoxicity and evolution of the systolic function in patients with breast cancer treated with anthracyclines

Cardiology Journal, 2022
BACKGROUND: Anthracycline cardiotoxicity (AC) may manifest years after treatment (long-term cardiotoxicity). There is little data on the incidence and natural history of AC in the current context, with protocols including lower anthracycline doses.

Leonurine Ameliorates Doxorubicin‐Induced Cardiotoxicity via STING/NF‐κB/NLRP3 Inflammasome Signaling Pathway

Advanced Science, EarlyView.
ABSTRACT Doxorubicin‐induced cardiomyopathy (DIC) remains a dose‐limiting clinical challenge. This study reveals that cardiac vascular endothelial cells (CVECs) act as initial sensors of doxorubicin cardiotoxicity: circulating doxorubicin activates the cGAS‑STING pathway in CVECs, triggering NLRP3 inflammasome‑mediated pyroptosis and release of ...

Non-familial cardiomyopathies in Lebanon: exome sequencing results for five idiopathic cases

BMC Medical Genomics, 2019
Background Cardiomyopathies affect more than 0.5% of the general population. They are associated with high risk of sudden cardiac death, which can result from either heart failure or electrical abnormalities.

The E3 Ligase RNF115 Aggravates Pathological Cardiac Hypertrophy via Ubiquitin‐Mediated Degradation of SPTBN1

Advanced Science, EarlyView.
In response to hypertrophic stimuli, increased c‑JUN phosphorylation upregulates RNF115, leading to SPTBN1 ubiquitination and degradation. which promotes F‑actin depolymerization and YAP activation, driving cardiac hypertrophy. The RNF115 inhibitor DTD effectively suppresses SPTBN1 ubiquitination and cardiac hypertrophy.

Atrial remodelling and dysfunction in hypertrophic cardiomyopathy: prognostic role and therapeutic target

Frontiers in Cardiovascular Medicine
IntroductionHypertrophic cardiomyopathy (HCM) is a common genetic cardiac disease marked by abnormal ventricular hypertrophy. Recent studies have highlighted that left atrial (LA) remodelling—including dilation, fibrosis, and functional impairment—plays ...

An Integrative Strategy Delineates Modular Metabolic Remodeling and Potential Therapeutic Targets Across Metabolic Diseases

Advanced Science, EarlyView.
An integrative single‐cell atlas across multiple metabolic diseases reveals coordinated metabolic modules and disease‐shared versus disease‐specific pathway activities. By systematically comparing scoring strategies, a robust RankAve framework is established. Coupled with network analysis and drug‐target prediction, this resource uncovers cross‐disease

ZER1 Restrains Pressure Overload‐Induced Cardiac Remodeling by Targeting DVL2 for Gly/N‐Degron‐Dependent Degradation

Advanced Science, EarlyView.
Pressure overload suppresses cardiomyocyte ZER1, weakening CRL2Zer1‐mediated DVL2 degradation and allowing DVL2 accumulation. Elevated DVL2 activates CaMKII‐HDAC4‐MEF2C signaling, drives fetal gene reactivation, and promotes pathological remodeling.

Reversible Cardiomyopathies

Clinical Medicine Insights: Cardiology, 2015
Cardiomyopathies (CMs) have many etiological factors that can result in severe structural and functional dysregulation. Fortunately, there are several potentially reversible CMs that are known to improve when the root etiological factor is addressed.
