Overview

Secondary prevention

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

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

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, smoking cessation and calcium channel blocker with maximum tolerated doses 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 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
