Risk factors for sudden death in individuals with HCM include a young age at first diagnosis (age < 30 years), an episode of aborted sudden death, a family history of HCM with sudden death of relatives, specific mutations in the genes encoding for troponin T and myosin, sustained supraventricular or ventricular tachycardia, ventricular septal wall thickness over 3 cm, hypotensive response to exercise, recurrent syncope (especially in children), and bradyarrhythmias (slow rhythms of the heart).[1]
