The investigators aim to compare the risk of mortality of Non-implantable carioverter defibrillator (ICD) vs. ICD management in patients with heart failure with reduced ejection fraction (HFrEF).
The proposed CONTEMP-ICD trial is a prospective, multicenter, open-label, randomized controlled trial; enrolling 3290 participants with HFrEF, on stable and optimal guideline-directed medical therapy (GDMT), who are eligible for a primary prevention ICD, but have a low predicted arrhythmic risk. Enrolled participants will be randomized in a 1:1 ratio to non-ICD vs. ICD treatment arms. The investigators hypothesize that, in participants with HFrEF who have a low predicted arrhythmic risk, non-ICD vs. ICD is non-inferior with respect to the primary endpoint of all-cause mortality and superior su…
