Hypertrophic Cardiomyopathy (HCM) is a genetic heart disease where the heart muscle, typically the left ventricle, thickens abnormally, hindering effective blood pumping. It's caused by mutations in sarcomere protein genes and is an autosomal dominant condition.

Symptoms vary widely; many individuals are asymptomatic, while others experience shortness of breath, chest pain, or palpitations, especially with exertion. Syncope (fainting), particularly during exercise, is a significant warning sign, and sudden cardiac death can be the first tragic indication in younger individuals. A detailed family history, including sudden deaths, is crucial for diagnosis.

In emergencies, an echocardiogram is the most valuable diagnostic tool to visualize the thickened muscle and blood flow obstruction. An ECG often shows left ventricular hypertrophy, and a physical exam might reveal a systolic murmur.

HCM is a leading cause of sudden cardiac death, primarily due to life-threatening arrhythmias like ventricular tachycardia or fibrillation, caused by the disorganized heart muscle. Risk stratification involves prior syncope, family history of sudden cardiac death, extreme wall thickness, and abnormal blood pressure response to exercise. High-risk patients may receive an implantable cardioverter-defibrillator (ICD).

Management is individualized, with beta-blockers or calcium channel blockers for symptomatic relief. For severe obstruction, septal myectomy or alcohol septal ablation may be considered. Heart transplant is a rare, end-stage option. Lifestyle modifications, such as avoiding strenuous competitive sports, are vital for all HCM patients.
