Video Summary

This module reviewed cardiomyopathies: ischemic, dilated, hypertrophic, and restrictive. Cardiomyopathy is heart muscle disease causing impaired function. Dilated cardiomyopathy features an enlarged, weakened left ventricle, often from viral, alcohol, or tachycardia causes, with heart failure symptoms and mitral regurgitation. Hypertrophic cardiomyopathy is usually autosomal dominant, with septal hypertrophy, impaired filling, exertional symptoms, and a systolic murmur that worsens with Valsalva. Restrictive cardiomyopathy causes stiff, non-dilated ventricles with atrial enlargement and diastolic dysfunction, often from infiltrative or storage diseases. Diagnosis uses labs, ECG, echo, MRI, and management targets reversible causes and heart failure therapy.
