• Moderate or greater interstitial lung disease (ILD) or ILD requiring chronic supplemental O2 therapy
• Severe or greater chronic obstructive pulmonary disease (COPD) or COPD requiring chronic supplementary O2 therapy
• History or evidence of any other clinically significant disorder, malignancy, active infection, other condition, or disease that, in the opinion of the Investigator or the Medical Monitor, would be an alternative explanation for heart failure symptoms (e.g., significant lung disease, anemia) and/or would pose a risk to patient safety or interfere with the study evaluation, procedures, or completion
