Brief Summary
The study is designed to substantiate the efficacy of Cardiac Contractility Modulation (CCM) in the heart failure population with ejection fraction ranging between 25 and 45%. The study is designed in an adaptive manner to ensure proper statistical significance and power of the primary efficacy evaluation.

Study Arms (2)
Device implant
OTHERPatients randomized to the treatment group will receive optimal medical therapy for heart failure. and implantation of the OPTIMIZER System.
Optimal medical therapy
ACTIVE COMPARATORPatients randomized to the control group will receive optimal medical therapy for heart failure.
Interventions
The OPTIMIZER System delivers non-excitatory cardiac contractility modulation (CCM) signals to the heart that are intended to influence myocardial properties in patients with chronic heart failure. The system has no pacemaker or implantable cardioverter-defibrillator (ICD) functions.
OMT using standard heart failure (HF) drugs
Eligibility Criteria
You may qualify if:
- Baseline ejection fraction ≥ 25% and ≤45% (as assessed by the site)
- NYHA class II or III (chronic, not transient, heart failure) despite receiving optimal medical therapy for heart failure
- Stable medication for heart failure for at least 30 days based on patient's medical records
- Baseline Peak VO2 ≥ 10 and ≤ 18.5 ml O2/Kg/min (as assessed by the site)
You may not qualify if:
- Potentially correctible cause of HF (valvular, congenital, or untreated ischemic heart disease)
- Clinically significant angina pectoris
- Hospitalization for HF requiring the use of inotropic support or IV diuretics within 30 days of enrollment
- PR interval greater than 375 ms
- Permanent or persistent atrial fibrillation/flutter or cardioversion within 30 days of enrollment.
- Exercise tolerance limited by condition other than heart failure (e.g., angina, chronic obstructive pulmonary disease (COPD), peripheral vascular disease, orthopedic or rheumatologic conditions) or unable to perform baseline stress testing
- Scheduled for a coronary artery bypass graft (CABG) or a percutaneous transluminal coronary angioplasty (PTCA) procedure, or CABG procedure within 90 days or a PTCA procedure within 30 days of enrollment.
- Biventricular pacing system, or indication for Biventricular pacing system
- Myocardial infarction within 90 days of enrollment.
- Mechanical tricuspid or aortic valves.
- Ventricular assist device
- Prior heart transplant
- Pregnant or planning to become pregnant during the study
- Age below 18
- Subject participating in another study, unrelated to CCM, at the same time (or within 30 days prior to enrollment to this study)
- +1 more criteria
