3. Left ventricular ejection fraction (LVEF) ≥20 % and \<50% on echocardiogram (ie, HFrEF participants) within 90 days prior to randomization (only for HFrEF participants in Group A and Group B).
4. Participants who, in the opinion of the investigator, require a right heart catheterization (not applicable for HFrEF patients not taking sacubitril/valsartan \[Group A\]).
5. Left ventricular ejection fraction (LVEF) ≥50% on echocardiogram (ie, HFpEF participants) within 90 days prior to randomization (only for HFpEF participants in Group C)

7. Pulmonary capillary wedge pressure (PCWP) ≥15 mmHg and right artrial pressure (RAP) \>5 mmHg on right heart catheterization (RHC) the morning of anticipated study drug dose administration (not applicable for HFrEF participants not taking sacubitril/valsartan \[Group A\] as described in the protocol).
8. Systolic blood pressure (SBP) ≥110 mmHg at the screening visit and on day -1
9. Hematocrit \>30% at the screening visit and day -1
Key Exclusion Criteria:
1. Currently taking IV vasodilators and/or inotropes
2. Taking sacubitril/valsartan (only for HFrEF and HFpEF participants not taking sacubitril/valsartan \[Group A and Group C, respectively\])
3. Taking a phosphodiesterase (PDE) inhibitor (eg, sildenafil), or a soluble guanylate cyclase stimulator (SGCS; ie, vericiguat) within 2 weeks of the screening visit or planning on taking valsartan/sacubitril, a PDE inhibitor, or a SGCS at any point during the study
4. More than moderate valvular regurgitation/stenosis (ie, moderate-to-severe or severe) on echocardiogram within 90 days prior to randomization
5. Known infiltrative or hypertrophic cardiomyopathy
6. Acute coronary syndrome within prior 6 months of randomization
7. History of cardiac arrest
8. Cardiac surgery within 3 months of randomization
9. Pacemaker or defibrillator placement within prior 30 days of randomization

11. Pulmonary arterial hypertension (World Health Organization \[WHO\] Group 1) and any medical history at any time of more than moderate pulmonary hypertension (ie, moderate-to-severe, or severe pulmonary hypertension, as described in the protocol
12. Congenital heart disease (repaired or unrepaired)
13. Inability to lie flat for cardiac catheterization
