- NYHA II-III
- Stable medications (for greater than 48hrs)
- Systolic BP greater than 90
Exclusion Criteria
- Exclusion Criteria - Part A Healthy Volunteers
Participants will not be enrolled if they meet any of the following criteria:
- If female, pregnant or lactating
- Receipt of any investigational agent or drug within 30 days or 5 half-lives (whichever is longer) prior to the first dose of Investigational product
- Use of prescription drugs within 4 weeks prior to first dosing. Subjects who have used over the counter medication excluding paracetamol, topical over the counter medications and routine vitamins but including megadose (intake of 20 to 600 times the recommended daily dose) vitamin therapy within 7 days of first dosing, unless agreed as non-clinically relevant by the Principal Investigator
- No clinically relevant findings in the medical history, laboratory examination and physical examination, especially with regards to cardiovascular system and renal function
- A positive urine test for drugs of abuse or alcohol at Screening or on the day of admittance to the Study Unit
- Normal dietary habits
- Any major surgical procedure within one month of entry into the study
- Have difficulties communicating reliably with the Investigator or unlikely to co-operate with the requirements of the study.
- Any other condition which in the view of the Investigator is likely to interfere with study or put the subject at risk.
Exclusion Criteria - Part B Heart Failure Patients
- Unstable heart failure including NYHA IV symptoms
- Treatment with intravenous inotropes or mechanical circulatory support.
- Unstable rhythm including frequent non-sustained ventricular tachycardia or poorly controlled atrial fibrillation (ventricular rate >100).
- Severe renal impairment Cr>200umol/L or dialysis.
- Life-threatening haematological, hepatic or pulmonary disease.
