COR LOE Recommendations I A In patients with LVEF of 35% or less that is due to ischemic heart disease who are at least 40 days post-MI and at least 90 days postrevascularization, and with NYHA class II or III HF despite GDMT, an ICD is recommended if meaningful survival of greater than 1 year is expected.S7.1.2-1,S7.1.2-2 I A In patients with LVEF of 30% or less that is due to ischemic heart disease who are at least 40 days post-MI and at least 90 days postrevascularization, and with NYHA class I HF despite GDMT, an ICD is recommended if meaningful survival of greater than 1 year is Value Statement: High Value (LOE: B-R) A transvenous ICD provides high value in the primary prevention of SCD particularly when the patient s risk of death due to a VA is deemed high and the risk of nonarrhythmic death (either cardiac or noncardiac) is deemed low based on the patient s burden of comorbidities and I B-R In patients with NSVT due to prior MI, LVEF of 40% or less and inducible sustained VT or VF at electrophysiological study, an ICD is recommended if meaningful survival of greater than 1 year is expected.S7.1.2-5 CLINICAL STATEMENTS AND GUIDELINES IIa B-NR In nonhospitalized patients with NYHA class IV symptoms who are candidates for cardiac transplantation or an LVAD, an ICD is reasonable if meaningful survival of greater than 1 year is expected.S7.1.2-6 S7.1.2-9 III: No Benefit C-EO An ICD is not indicated for NYHA class IV patients with medication-refractory HF who are not also candidates for cardiac transplantation, an LVAD, or a CRT defibrillator that incorporates both pacing and defibrillation capabilities.
