The coexistence of GLA (Pro259Ser, c.775C>T) and MYBPC3 (c.1351+2T>C) mutations was found in a female patient with hypertrophic cardiomyopathy. Histology documented abundant vacuolisation with osmiophilic lamellar bodies and positive Gb3 immunohistochemistry. In the presence of a hypertrophic cardiomyopathy phenotype, the systematic search for unusual findings is mandatory to rule out a phenocopy.

Hypertrophic cardiomyopathy (HCM) is a major contributor to cardiovascular diseases (CVD), the leading cause of death globally. HCM can precipitate heart failure (HF) by causing the cardiac tissue to weaken and stretch, thereby impairing its pumping efficiency. Moreover, HCM increases the risk of atrial fibrillation, which in turn elevates the likelihood of thrombus formation and stroke.

Chronic stress-induced cardiac hypertrophy remains a critical precursor to heart failure, with current therapies limited by incomplete mechanistic targeting. Cyclin-dependent kinases (CDKs), pivotal regulators of cell cycle and stress signaling, are emerging therapeutic targets in cardiovascular pathologies. Using bioinformatics analysis of human hypertrophic cardiomyopathy datasets (GSE5500, GSE136308) and a murine transverse aortic constriction (TAC) model, we investigated the therapeutic effects of the CDK inhibitor R547 (10 mg/kg, intraperitoneal every 3 days) on pressure overload-induced cardiac remodeling.

Background: Proper risk stratification tools for patients with obstructive hypertrophic cardiomyopathy (oHCM) undergoing septal myectomy are lacking. Our objective was to assess the predictive value of preoperative N-terminal pro-brain natriuretic peptide (NT-proBNP) on perioperative outcomes and late survival in patients with oHCM undergoing transaortic septal myectomy.
Methods: Between 2008 and 2021, 834 patients with preoperative NT-proBNP measurements underwent septal myectomy.

Background: Alcohol septal ablation (ASA) is an established therapy for symptomatic hypertrophic obstructive cardiomyopathy (HOCM) in patients unresponsive to medical treatment. However, comprehensive assessment of ASA outcomes remains challenging. This study aimed to evaluate the impact of institutional experience and patient characteristics on achieving complete clinical and haemodynamic response (CCHR), a novel composite outcome integrating long-term symptomatic, haemodynamic, safety, and major clinical endpoints, including survival and resuscitation.
