Hypertrophic Cardiomyopathy
Prognosis for Hypertrophic Cardiomyopathy
Overall, annual mortality is about 1% for adults but is higher for children. Death is usually sudden, and sudden death is the most common sequela; chronic heart failure occurs less often. A higher risk of sudden cardiac death is predicted by the presence of the following risk factors: Family history of sudden cardiac death due to hypertrophic cardiomyopathy, cardiac arrest, or sustained ventricular arrhythmias Personal history of unexplained syncope, cardiac arrest, or sustained ventricular arrhythmias Multiple repetitive non-sustained ventricular tachycardia (on ambulatory ECG) Massive left-ventricular hypertrophy (thickness ≥ 30 mm), LV dysfunction (EF < 50%) , LV apical aneurysm Extensive and diffuse late gadolinium enhancement on MRI
