Multicenter Randomized Controlled Trial of Cardiac Contractility Modulation in Patients With Advanced Heart Failure - FIX-HF-5 — Presented at ACC.09/i2


The goal of the trial was to evaluate cardiac contractility modulation plus optimal medical therapy compared with optimal medical therapy alone in patients with advanced heart failure. Cardiac contractility modulation is nonexcitatory electrical signals delivered during the refractory period with the aim to improve contractility.
