Video Summary

The module reviews cardiomyopathies: ischemic, dilated, hypertrophic, and restrictive. Cardiomyopathy is heart muscle disease causing impaired structure or function. Dilated cardiomyopathy features an enlarged left ventricle with reduced ejection fraction, often causing heart failure symptoms and mitral regurgitation. Hypertrophic cardiomyopathy is usually autosomal dominant, with septal hypertrophy, outflow obstruction, exertional symptoms, syncope, and risk of sudden death. Restrictive cardiomyopathy causes impaired filling of non-dilated ventricles, often from infiltrative or storage diseases. Diagnosis uses labs, ECG, echocardiography, MRI, and monitoring. Treatment includes addressing causes, guideline-directed therapy, septal reduction, mavacamten, and specialist referral.
