Sudden cardiac death (SCD) risk assessment among patients with nonischemic cardiomyopathy (NICM) has been has been less straightforward than for patients with ischemic cardiomyopathy. Goldberger JJ(1), Subačius H(2), Patel T(2), Cunnane R(3), Kadish AH(4). Cardiomyopathy is a group of diseases that affect the heart muscle. Purpose of review: Non-ischaemic dilated cardiomyopathy (DCM) occurs in 1 in 2500 individuals in the general population and is associated with considerable morbidity and mortality. 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). Restrictive Cardiomyopathy : this type of cardiomyopathy is less common and occurs due to the development of abnormal rigidity of the heart muscle. 2020 Jun;6(6):591-608. doi: 10.1016/j.jacep.2020.03.010.

Figure 4 Several changes occur in patients with dilated cardiomyopathy that increase the risk of sudden cardiac death. Current guidelines recommend the use of implantable cardioverter-defibrillators (ICDs) for primary prevention of sudden cardiac death (SCD) in patients with nonischemic dilated cardiomyopathy (NIDCM), symptomatic heart failure, and left ventricular ejection fraction (LVEF) ≤ 35%. Techniques incorporating functional parameters, depolarization abnormalities, repolarization abnormalities, and arrhythmic markers provide only modest risk stratification for sudden cardiac death in patients with nonischemic dilated cardiomyopathy. Conversely, community-based studies have demonstrated that many at-risk individuals who may benefit from ICD therapy remain unprotected. 2017 Jun;35(3). Sudden cardiac death (SCD) is an important cause of mortality worldwide. An irregular heart beat and fainting may occur. Although SCD is most often associated with coronary heart disease, the risk of SCD in patients without ischemic heart disease is well-established.
