Ki vehet részt

• Adult patients who meet all the following criteria at screening may be included in the study:
• Are between ≥ 18 years and ≤ 85 years at the signing of informed consent
• Have a history of chronic HFrEF, defined as requiring treatment for HF for a minimum of 3 months prior to screening
• Are receiving oral loop diuretics on a regular schedule
• Patients without AFF on screening ECG:; LVEF < 30% within 6 months of screening; Elevated N-terminal prohormone of B-type natriuretic peptide (NT-proBNP) ≥ 1000 pg/mL (BNP ≥ 300 pg/mL)
• Patients with AFF on screening ECG:; LVEF < 25% within 6 months of screening; Elevated N-terminal prohormone of B-type natriuretic peptide (NT-proBNP) ≥ 3000 pg/mL (BNP ≥ 900 pg/mL); Not currently taking digoxin
• Meet one of the following criteria for a recent HF event:; Are currently hospitalized with the primary reason of HF; Had an HF event (as defined in the primary endpoint) within 12 months prior to screening. For the purposes of a qualifying HF event, subcutaneous furosemide will be treated as equivalent to intravenous furosemide Or; Had outpatient escalation of oral diuretics due to worsening signs and symptoms of heart failure plus one of two additional criteria sustained for at least 1 week: (1) at least 50% or 1.5-fold increase in daily loop-diuretic-equivalent dose; (2) the addition of a new diuretic class to a loop diuretic
• Are established on regional standard-of-care HF therapies for at least 30 days prior to screening
• Systolic blood pressure ≤ 140 mmHg

• Have an estimated glomerular filtration rate (eGFR) < 20 mL/min/1.73m2 or receiving dialysis at screening
• Any of the following criteria will exclude potential patients from the study:
• Are admitted to a long-term care facility or hospice
• Have a projected survival of < 12 months due to non-cardiovascular causes based on clinical judgment
