• Presence of severe, clinical right heart failure.
• Symptoms of unstable angina, a myocardial infarction, cardiac surgery, or percutaneous coronary intervention within 1 month prior to Screening
• Have coronary artery disease likely to require coronary artery bypass grafting or percutaneous coronary intervention during the ensuing 3 months.
• Had cardiac arrest or a sustained ventricular tachycardia considered life threatening and requiring intervention within 3 months, unless treated with implantable cardioverter-defibrillator.
