(A) At the cellular level, the action potential is altered due to changes in ionic currents. As with coronary artery disease, large-scale clinical trials evaluating implantable cardioverter defibrillator (ICD) therapy based on noninvasive risk markers have focused largely on left ventricular ejection fraction (LVEF). Cardiomyopathy can lead to heart failure.The main types of cardiomyopathy include dilated, hypertrophic and restrictive cardiomyopathy. Implantable cardioverter defibrillators for primary prevention in patients with nonischemic cardiomyopathy: A systematic review and meta-analysis. Cardiovasc Ther. Ventricular tachyarrhythmia accounts for the majority of SCDs and can be caused by various underlying heart diseases, the most frequent being ischaemic cardiomyopathy. JAMA. Epub 2017 Mar 23.

Identifying patients who are at highest risk for SCD is an ongoing challenge. This is in contrast to other studies, which revealed a strong association between nsVTs and the risk of sudden death. Previous data have shown that various nonischemic cardiac diseases account for about 20% of sudden cardiac deaths (SCDs) and that dilated and hypertrophic cardiomyopathy (CM) are major causes of nonischemic SCD. Various promising techniques for further risk stratification are under evaluation, including cardiac magnetic resonance imaging, electrocardiographic assessment of electrical instability, and genetic testing. link. 2017 Nov;28(11):1361-1366. doi: 10.1111/jce.13284.
