Hypertrophic Cardiomyopathy

Also known as HCM, HOCM, hypertrophic obstructive cardiomyopathy, MYBPC3/MYH7

Hypertrophic Cardiomyopathy is the most common inherited heart muscle disease, characterised by unexplained left ventricular hypertrophy, myocardial fibre disarray, and increased risk of sudden cardiac death, particularly in young athletes.

About Hypertrophic Cardiomyopathy

Hypertrophic Cardiomyopathy is the most common inherited heart muscle disease, characterised by unexplained left ventricular hypertrophy, myocardial fibre disarray, and increased risk of sudden cardiac death, particularly in young athletes. Mutations in genes encoding sarcomeric proteins, most frequently MYBPC3 and MYH7, are identified in approximately 60% of familial cases. Clinical presentation is highly variable, ranging from lifelong asymptomatic hypertrophy to severe heart failure and ventricular arrhythmia, with the outflow tract obstruction variant (HOCM) being amenable to cardiac myosin inhibitor therapy.

Common clinical features

Exertional dyspnoea and reduced exercise toleranceChest pain (angina) on exertionPalpitations and awareness of irregular heartbeatPre-syncope or syncope, particularly with exertionLeft ventricular wall thickness greater than 15mm on echocardiographyDynamic left ventricular outflow tract obstructionMitral regurgitation due to systolic anterior motionIncreased risk of sudden cardiac death in high-risk individuals

Before you apply

Things trial teams commonly ask about for Hypertrophic Cardiomyopathy. Not eligibility rules; those are set by each study.

  • Genotype status (sarcomere-positive vs. genotype-negative HCM) affects eligibility for some precision trials; ensure comprehensive sarcomere gene panel testing has been performed.
  • Resting and provoked left ventricular outflow tract gradient measurements are central eligibility criteria for cardiac myosin inhibitor trials; bring current echocardiography reports.
  • History of septal reduction procedures (surgical myectomy or alcohol septal ablation) may exclude participation in some trials; disclose all prior interventions.
