A Multicenter, Randomized, Double-blind, Double Dummy, Parallel Group, Active-controlled 8-week Study to Evaluate the Effect of Sacubitril/Valsartan (LCZ696) Versus Enalapril on Changes in NT-proBNP and Safety and Tolerability of In-hospital Initiation of LCZ696 Compared to Enalapril in HFrEF Patients Who Have Been Stabilized Following Hospitalization for Acute Decompensated Heart Failure (ADHF).
A Multicenter, Randomized, Double-blind, Double Dummy, Parallel Group, Active-controlled 8-week Study to Evaluate the Effect of Sacubitril/Valsartan (LCZ696) Versus Enalapril on Changes in NT-proBNP and Safety and Tolerability of In-hospital Initiation of LCZ696 Compared to Enalapril in HFrEF Patients Who Have Been Stabilized Following Hospitalization for Acute Decompensated Heart Failure (ADHF).
The purpose of this study was to assess the effect of in-hospital initiation of sacubitril/valsartan (LCZ696) vs. enalapril on time averaged proportional change in NT-proBNP in patients who have been stabilized following hospitalization for acute decompensated heart failure (ADHF) and reduced ejection fraction (left ventricular ejection fraction (LVEF) ≤ 40%).
Key Inclusion Criteria:
Possess the capacity to provide written informed consent which must be obtained before any assessment is performed.
Currently hospitalized for ADHF. Patients with a diagnosis of acute heart failure had to have symptoms and signs of fluid overload (i.e. jugular venous distention, edema or rales on auscultation or pulmonary congestion on chest x-ray) at time of hospitalization.
Eligible patients will be randomized no earlier than 24 hours and up to ten days after presentation while still hospitalized as long as meet the following definition of stable status:
LVEF ≤40% within the past 6 months (including current hospitalization) using echocardiography, multi gated acquisition scan (MUGA), CT scanning, MRI or ventricular angiography, provided no subsequent study documented an EF of >40%.
Elevated NT-proBNP ≥ 1600pg/mL OR BNP ≥400 pg/mL during current hospitalization.
