Eligibility criteria:

        Inclusion Criteria

          1. Patient is male, or female of non-childbearing potential (two years post-menopausal or
             surgically sterilized)

          2. Female patients must have a negative urine pregnancy test prior to entry into the
             study

          3. Patient is 18 years old or greater

          4. Patient has given signed informed consent

          5. Patient is considered to be in suitable health in the opinion of the investigator, as
             determined by:

               -  A pre-study physical examination with no clinical abnormalities which in the
                  opinion of the investigator would preclude participation in the study other than
                  physical symptoms or signs consistent with stable heart failure

               -  An electrocardiogram (ECG) with no abnormalities in the opinion of the
                  investigator that would impair assessment of stopping criteria

          6. Patient has pre-study clinical laboratory findings that are within normal range, or if
             outside of the normal range, should not preclude participation in the study in the
             opinion of the investigator (see Exclusion Criteria, below, for exceptions)

          7. Patient has a documented diagnosis of heart failure with an ejection fraction of less
             than 40%

          8. Patient has been on a stable dose of a beta blocker and an ACE (angiotensin-converting
             enzyme) inhibitor or an ARB (angiotensin II receptor blocker) for at least 4 weeks. If
             prescribed, diuretics must have been administered according to a consistent regimen
             for at least 4 weeks

          9. Patient is currently in sinus rhythm

         10. Patient has interpretable echocardiographic images on a screening echocardiogram

        Exclusion Criteria

          1. Patient has been hospitalized for heart failure, myocardial infarction, coronary
             revascularization, or another cardiac indication within the last 6 weeks

          2. Patient has a current history of alcohol use which in the opinion of the investigator
             would preclude participation in the study

          3. Patient has a current history of drug abuse

          4. Patient has donated blood or blood products within 30 days prior to screening

          5. Patient has Canadian Cardiovascular Society (CCS) Class III or IV angina

             disease

          7. Patient has had a valve replacement

          8. Patient is pacemaker dependent

          9. Patient is on chronic anti-arrhythmic therapy, with the exception of amiodarone

         10. Patient is currently taking, or has taken in the last 7 days, a CYP3A4 inhibitor or
             inducer medication

         11. Patient has a history of hypertrophic obstructive cardiomyopathy

             Filtration Rate (GFR) ≤ 35 ml/min/1.73 m2

         16. Patient has a potassium < 3.5 mEq/L or > 5.5 mEq/L

         17. Patient has a sodium ≤ 133 mEq/L

         18. Patient has a urea > 15 mmole/L

         19. Patient has a troponin I or T at screening that is detectable at the investigative
             site's clinical laboratory

         20. Patient has a hemoglobin < 11 gm/dL in males or < 10 gm/dL in females

         21. Patient has an alanine transaminase (ALT), aspartate transaminase (AST), alkaline
             phosphatase (ALKP) or total bilirubin (TBILI) > 3 times the upper limit of normal
