Does daily remote monitoring reduce mortality and heart failure hospitalization in patients with implantable cardioverter-defibrillators?
Daily remote monitoring of ICDs reduces all-cause mortality and heart failure hospitalizations, likely driven by the prevention of heart failure exacerbations.
In a pooled analysis of the three trials, HM reduced all-cause mortality and the composite endpoint of all-cause mortality or WHF hospitalization. The similar magnitudes of absolute risk reductions for WHF and CV endpoints suggest that the benefit of HM is driven by the prevention of heart failure exacerbation.
Hindricks et al. (2017) studied this question.
