Overview

Secondary prevention strategies following SCA and unstable VT include ICD implantation, and medications. Based on meta-analysis of AVID trial implantation of ICD for secondary prevention of ventricular arrhythmia was superior to antiarrhythmic drugs in patients who survived of sudden cardiac arrest or unstable VT. Before ICD implantation, the reversible causes of ventricular arrhythmia including myocardial ischemia, electrolyte disturbance, proarrhythmic medication effect may be corrected. ICD implantation improved outcome in well-tolerated VT and structurally heart disease. Among patients with ischemia heart disease and syncope due to inducible sustained monomorphic VT, ICD is recommended even if there is not other criteria for primary prevention.

Secondary prevention

Secondary prevention strategies following SCA and unstable VT include ICD implantation, and medications.

Secondary prevention in patients with ischemic heart disease

Recommendations for secondary prevention of sudden cardiac death in ischemic heart disease
ICD implantation (Class I, Level of Evidence B):

❑ In patients with IHD and survivors of SCD due to VT, VF or hermodynamically unstable VT or incessant VT with irreversible cause, ICD should be implanted if survival is more than 1 year.

ICD implantation (Intermediate value statement, Level of Evidence B) :

❑ In patients with higher risk of death due to ventricular arrhythmia and lower risk of non cardiac death due to other comorbidities, ICD implantation has intermediate value.

ICD implantation : (Class I, Level of Evidence B)

❑ In patients with IHD and unexplained syncope with induction of sustained monomorphic VT in EPS, ICD implantation is recommended if life expectancy is more than 1 year

Secondary prevention in patients with coronary spasm


Recommendations for secondary prevention of sudden cardiac death in coronary spasm
ICD implantation (Class I, Level of Evidence B):

❑ In patients with ventricular arrhythmia due to coronary artery spasm, vasodilator such as calcium channel blocker with maximum tolerated doses smoking cessation and is recommended

ICD implantation (Class IIa, Level of Evidence B) :

❑ In survival of SCA due to coronary artery spasm with ineffective or not tolerated medications, ICD implantation is recommended if the survival is more than 1 year

ICD implantation : (Class IIb, Level of Evidence B)

❑ In survival of SCA due to coronary artery spasm, ICD implantation in addition to medical therapy is recommended if life expectancy is more than 1 year

Secondary prevention in non-ischemic cardiomyopathy

Recommendations for secondary prevention of sudden cardiac death in non-ischemic cardiomyopathy
ICD implantation (Class I, Level of Evidence B):

❑ ICD implantation is recommended in survivors of SCA or hemodynamically unstable VT or sustained VT not related to reversible causes, if life expectancy is more than 1 year

ICD implantation, EPS study (Class IIa, Level of Evidence B) :

❑ In the presence of syncope presumed due to ventricular arrhythmia, ICD or EPS study for risk stratification of SCD is recommended if survival is more than 1 year

Amiodarone : (Class IIb, Level of Evidence B)

❑ In survival of SCA, or sustained VT, or symptomatic ventricular arrhythmia who are ineligible for ICD implantation due to limited life expectancy or inaccessible venous sites, amiodarone is recommended
