Most sudden deaths are cardiac, and most sudden cardiac deaths are related to arrhythmias secondary to structural heart disease or primary electrical abnormalities of the heart. Thanks to the growing awareness in the medical community as well as advances in diagnostic techniques HCM can be diagnosed at earlier stages than ever before. Severe heart failure is the stem for sudden death in patients with ischemic or nonischemic cardiomyopathy. The most common structural disease leading to sudden death is ischemic heart disease. Patients without structural disease have a primary electrical abnormality, such as long-QT syndrome or Brugada syndrome. Nonischemic cardiomyopathy and other structural abnormalities such as arrhythmogenic ventricular dysplasia and hypertrophic cardiomyopathy may also be causative. In other conditions, other markers for structural heart disease and electrical abnormalities need to be considered. The implantable cardioverter defibrillator is the most effective treatment strategy in some patients.
