Cardiac Implantable Electronic Devices in Ischemic Cardiomyopathy

This review discusses the range of device therapy for ischemic cardiomyopathy (ICM). This article will review the primary data supporting guideline indications for cardiac implantable electronic devices in patients with ICM, with a focus on primary/secondary prevention transvenous implantable cardioverter defibrillators (ICDs), cardiac resynchronization therapy, and subcutaneous/extravascular ICDs. In addition, this review discusses emerging device therapy for ICM including left bundle area pacing/defibrillation, cardiac contractility modulation and baroflex activation therapy. Device therapy for ICM continues to evolve to incorporate diverse modalities across the spectrum from prevention of sudden cardiac death to modifying cardiac remodeling and recovery.
