A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Self- and Goal-Directed Valsalva Maneuver vs Exercise in Eliciting Left Ventricular Outflow Tract Obstruction

JACC: Advances
Background: In symptomatic patients with hypertrophic cardiomyopathy (HCM), eliciting left ventricular outflow tract obstruction (LVOTO) is critical. A self-directed Valsalva (SDV) and exercise (EX) are frequent tools used to unmask obstruction in HCM ...

Syndrome of Reversible Cardiogenic Shock and Left Ventricular Ballooning in Obstructive Hypertrophic Cardiomyopathy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Cardiogenic shock from most causes has unfavorable prognosis. Hypertrophic cardiomyopathy (HCM) can uncommonly present with apical ballooning and shock in association with sudden development of severe and unrelenting left ventricular (LV ...

Metabolic Memory in Cardiovascular Disease: Encoding, Propagation, and Therapeutic Targeting

Advanced Science, EarlyView.
Cardiovascular risk often persists after metabolic abnormalities are corrected. This conceptual Review frames such persistence as metabolic memory, encoded through a narrowing therapeutic window from reversible marks to irreversible damage, with continuous input from peripheral organs.

Real‐World Observations in Patients With Obstructive Hypertrophic Cardiomyopathy Treated With Mavacamten: Evidence of Favorable Disease Modification

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Mavacamten is commercially approved for use in symptomatic patients with obstructive hypertrophic cardiomyopathy. This study evaluated its real‐world impact on symptoms, echocardiographic changes, and the need for septal reduction therapy in ...

Hypertrophic cardiomyopathy in athletes [PDF]

European Cardiology Review, 2017
The diagnosis of hypertrophic cardiomyopathy can be challenging in the athlete. A morphologically mild phenotype of the condition may mimic physiological left ventricular hypertrophy and requires careful evaluation of the athlete with an array of clinical tools.

Role of modifying genes on the severity of rare mutation of MYH7 gene in hypertrophic obstructive cardiomyopathy [PDF]

, 2012
Hypertrophic Cardiomyopathy (HCM) is an autosomal dominant disorder due to mutations in sacromeric genes with variable penetrance. Hypertrophic Obstructive Cardiomyopathy (HOCM) is a major complication of Hypertrophic Cardiomyopathy.

KLF5 Downregulation Links Impaired BNIP3‐Mediated Mitophagy to Inflammatory Valve Remodeling in Calcific Aortic Valve Disease

Advanced Science, EarlyView.
In human CAVD, KLF5 is reduced in VIC‐rich regions and remodeling/stress‐associated VIC states. In VICs, KLF5 sustains BNIP3 promoter activity and BNIP3‐mediated mitophagy, thereby limiting cytosolic mtDNA accumulation. KLF5 loss weakens mitochondrial quality control and enhances mtDNA‐sensitive STING/NF‐κB/NLRP3 inflammatory signaling under osteogenic

Mid-Ventricular Hypertrophic Obstructive Cardiomyopathy [PDF]

, 2014
Mid-ventricular hypertrophic obstructive cardiomyopathy is a rare variant form (1%) of hypertrophic obstructive cardiomyopathy. In this case, we report a patient referred for elective cardiac catheterization due to angina and dyspnea on moderate exertion,

SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

Advanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced
