Study Overview
Brief Summary
The primary objective of this study is to evaluate the impact of Cardiac Contractility Modulation (CCM) therapy on the initiation and up-titration of Guideline-Directed Medical Therapy (GDMT) in patients with heart failure (HF). This will be assessed by the change in Quad Medication Score (QMS) from baseline (pre-CCM) to 6-month following post-CCM device implant.
Detailed Description
Design Prospective, non-randomized, comparison analysis of medication use and dosing at pre/post CCM therapy. The Fix-GDMT-HF study aims to enroll up to 200 subjects (100 in Investigational Arm and up to 100 in Registry Arm). Subjects identified not eligible to participate in the investigational arm can participate in the registry arm.
Method
- Subjects with QMS ≤ 5, eGFR ≥15, diagnosed symptomatic heart failure and LVEF ≤40% will be enrolled after review and approval by a member of the steering committee. Eligible subjects will receive CCM therapy and be enrolled in the investigational arm of the study. Medication optimization(Med op#2) will be assessed after implantation(approx. 3month post implant), followed by evaluation of QMS and other endpoints at 6 and 12 months. A target of 100 patients will be enrolled in the investigational arm.
- After medical optimization (Med op# 1), if the patient has QMS > 5 or identified during SC review as not eligible to participate in investigational arm can participate in the registry arm. They will continue treatment guided by local practice (including potential CCM implant) with QMS assessment (and other data collection as patients in investigational arm) at 6- and 12-month visit. The registry arm will be restricted to 100 patients.
