Overview
Secondary prevention
Abbreviations:
MI: Myocardial infarction;
VT: Ventricular tachycardia;
VF: Ventricular fibrillation;
LVEF: Left ventricular ejection fraction;
ICD: Intracardiac defibrillation;
NYHA: New York Heart Association functional classification;
LVAD: Left ventricular assist device;
EPS: Electrophysiology study
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 high risk of death due to ventricular arrhythmia and low 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 |
