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) |
(Class III, Level of Evidence C) |
❑ ICD is not beneficial in patients with NYHA class 4 despite optimal medical therapy who are not candidates for cardiac transplantation or LVAD |
