Eligibility Criteria

• Age: 18 Years - 85 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Participants with New York Heart Association (NYHA) Class II-III.
• Cohort 1 - Left Ventricular Ejection Fraction (LVEF) ≤ 40%.
• Cohort 2 - Left Ventricular Ejection Fraction (LVEF) \>40% and ≤ 65%, elevated N-terminal pro B-type natriuretic peptide (NT-proBNP) ≥ 600pg/mL and atrial fibrillation/flutter.
• Stable heart failure and on optimal medical therapy.
• Screening hemoglobin ≥ 9.0 g/dL.

You may not qualify if:

• Uncontrolled hypertension.
• Sustained systolic Blood Pressure (BP) \< 90 mmHg and/or diastolic BP \< 50 mmHg on 2 consecutive (duplicate seated) readings at screening.
• Heart failure due to hypertrophic cardiomyopathy, restrictive and/or infiltrative cardiomyopathy, arrhythmogenic right ventricular dysplasia, Fabry disease, or Noonan syndrome with LV hypertrophy or a positive serum immunofixation result.
• Diagnosis of stress-induced (Takotsubo) cardiomyopathy, myocarditis, or peripartum cardiomyopathy.
• Diagnosis of chemotherapy- or radiation-induced cardiomyopathy.
• Diagnosed with stroke or Transient Ischemic Attack (TIA) within 12 weeks of screening.
• History of syncope within the last 12 weeks prior to screening or sustained ventricular tachycardia without an implantable cardioverter-defibrillator.
• Moderate or severe aortic and/or mitral valve stenosis.
• Medically documented unstable angina, acute coronary syndrome (e.g., myocardial infarction, troponin-positive with symptoms of angina or unstable angina) within the last 8 weeks prior to start of screening.
• Medically documented ST-elevation myocardial infarction within 12 weeks of screening.
• Any tachycardia (inclusive of Atrial Fibrillation (AF) or atrial flutter) with a resting ventricular rate \> 110 beats per minute at screening.
• For participants with a history of AF or atrial flutter, not on adequate anticoagulant therapy via non-vitamin K oral anticoagulants or warfarin if the CHA2DS2-VASc score is ≥ 2 in men or ≥ 3 in women or per local guidelines. Percutaneous occlusion of the left atrial appendage alone is not adequate.
• AF ablation within the last 12 weeks prior to screening or planned during the study duration.
• Symptomatic bradycardia or second (Mobitz Type II)- or third-degree heart block without a pacemaker.
• Cardiac surgery, coronary artery revascularization or indication for coronary artery revascularization, percutaneous coronary intervention, valve repair/replacement or valvuloplasty within 12 weeks prior to screening.
