Hypertrophic cardiomyopathy

Hypertrophic cardiomyopathy is a condition in which a portion of the myocardium is hypertrophied without any obvious cause. It is a leading cause of disabling cardiac symptoms and sudden, unexpected cardiac death in any age group. It is believed to be due to a mutation in one of many genes. Depending on the degree of obstruction of the outflow of blood from the left ventricle of the heart, it can be classified as obstructive or non-obstructive. Diagnosis is mainly by Echocardiography.

Management consists of alleviating symptoms by decreasing the left ventricular outflow tract gradient and symptoms of dyspnoea, chest pain and syncope. The first treatment is a beta-blocker/ calcium channel blocker. Most patients can be managed medically without needing to resort to surgical intervention.
