Prior chronic treatment, or prescription, with a loop diuretic (for example, furosemide, torsemide, bumetanide) for ≥30 days prior to the index event. Medical records, discharge notes and physician referral letters may serve as documentation for prior chronic treatment with a loop diuretic |

|
|
|
|
Had evidence of clinical HF syndrome consisting of |
|
|
|
|
Documented LVEF of ≥50% within 12 months prior to screening; as measured by |
|
|
|
|
echocardiography, radionuclide ventriculography, invasive angiography |
|
|
|
|
dyspnea |
|
|
|
|
magnetic resonance imaging (MRI), or computerized tomograph (CT) |
|
|
|
|
jugular venous distention |
|
|
|
|
Evidence of documentation of LVEF of ≥50% may also include participant medical records, discharge notes or a referral letter from the participant's physician or referring physician that details the participant's medical history |
|
|
|
|
pitting edema in lower extremities (>1+) |
|
|
|
|
Hospitalization for worsening heart failure (WHF) with intravascular volume overload (the index event), as determined by the investigator, based on appropriate supportive documentation at randomization, and defined by ≥2 of the |
|

|
|
ascites |
|
|
|
|
pulmonary congestion on chest X-ray |
|
|
|
|
following |
|
|
|
|
pulmonary rales AND participant received treatment with IV diuretics |
|
|
|
|
OR |
|
|
|
|
Treatment for an urgent visit outside of of being hospitalized with WHF and intravascular volume overload (the index visit) requiring treatment with IV diuretics (defined as ≥2 IV doses) such as in the outpatient setting/emergency room/observation unit/infusion clinic with a clinical response within the past 2 weeks prior to randomization. Urgent visit is defined as an unplanned visit for HF defined by ≥2 of the following |
|
|
|
|
dyspnea |
|

|
|
|
|
NT-proBNP (>300 [sinus rhythm] or 900 picograms/milliliter (pg/mL) [atrial |
|
|
|
|
fibrillation or atrial flutter] OR brain natriuretic (BNP) (>100 [sinus |
|
|
|
|
rhythm] or 300 pg/mL [atrial fibrillation or atrial flutter]) at screening |
|
|
|
|
Note: The presence or absence of atrial fibrillation or atrial flutter to determine the |
|
|
|
|
appropriate cut-off for a given BNP or NT-proBNP sample should be evaluated using |
|
|
|
|
electrocardiogram (ECG) performed at screening prior to the collection of the BNP or |
|
|
|
|
NT-proBNP sample |
|
|
