What this trial studies

This study aims to assess the effects of Cardiac Contractility Modulation (CCM) therapy on the initiation and adjustment of Guideline-Directed Medical Therapy (GDMT) in patients suffering from heart failure. It involves a prospective, non-randomized analysis of medication use and dosing before and after the CCM therapy. A total of 100 subjects will be enrolled, and their Quad Medication Score (QMS) will be evaluated at baseline and again at 6 and 12 months following the CCM device implant to determine the therapy's impact on medication optimization.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with symptomatic heart failure and reduced ejection fraction (LVEF ≤40%).

Not a fit: Patients with a Quad Medication Score greater than 5 or significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance medication management for heart failure patients, potentially improving their overall health outcomes.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in optimizing heart failure treatment through device-assisted therapies.
