Contemporary Use of Implantable Cardioverter-Defibrillators in the Era of 4-Pillar Heart Failure Therapy---an International Survey.

ABSTRACT:

Background

Optimized 4-pillar guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) has significantly altered clinical practice, with a coinciding decrease in sudden cardiac death. The continued role for implantable cardioverter-defibrillators (ICDs) in primary prevention of sudden death has recently been debated in the context of residual arrhythmic risk. This survey explored contemporary attitudes toward primary prevention ICD use in ischemic and nonischemic cardiomyopathy.

Methods

An international, REDCap-based survey targeting clinicians involved in HFrEF management assessed the impact of GDMT on ICD decision-making, clinical thresholds used for implantation, and willingness to participate in randomized controlled trials.
