Association of Heart Failure Aggravation and Device-based Sensor Parameters

This is a prospective, multicenter, observational patient registry designed to evaluate the association between changes in device-based sensor parameters and heart failure (HF) aggravation in patients implanted with Boston Scientific implantable cardioverter-defibrillators (ICDs) or cardiac resynchronization therapy defibrillators (CRT-Ds) equipped with HeartLogic™, Sleep Incline, and Apnea Scan functions. The study will prospectively collect remote monitoring and clinical follow-up data to determine whether changes in individual or combined device-based sensor parameters are associated with worsening HF events and to evaluate the clinical utility of remote monitoring for HF management.
