Cardiologists at the University of Arizona Sarver Heart Center are recruiting patients with heart failure for a clinical research study that is evaluating a cardiac contractility modulation (CCM) investigational device.

The study, “Evaluate Safety and Efficacy of the OPTIMIZER® System in Subjects With Moderate-to-Severe Heart Failure: FIX-HF-5C,” is looking for patients who are 18 years and older and have been told they have heart failure with symptoms that are limiting their daily living activities.

The CCM investigational device delivers special electrical signals to the heart. Unlike a pacemaker, the CCM signals do not initiate a new heartbeat or change the rate at which the heart beats. Rather, these signals are intended to enhance the strength (contractility) of the heartbeat.

Peter Ott, MD, an associate professor of clinical medicine at the UA Sarver Heart Center and a cardiologist who specializes in treating heart rhythm disorders, is the UA’s principal investigator for this study, sponsored by Impulse Dynamics.
