Experimental: sacubitril/valsartan (LCZ696)
Initial dose for patients randomized to sacubitril/valsartan (LCZ696) was determined by the blood pressure at the time of randomization. Study treatment was titrated to the target dose of sacubitril/valsartan (LCZ696) 97/103 mg bid (Dose Level 3). Titration was based on blood pressure at the time of the visit. Dose adjustments were only allowed if indicated per protocol defined safety and tolerability criteria and investigator judgement. Patients were required to take a total of two tablets twice daily (one tablet of active sacubitril and valsartan and one tablet of enalapril matching placebo pack). |
Drug: sacubitril/valsartan (LCZ696)
sacubitril/valsartan (LCZ696) tablet with minimum dose 24/26 mg, maximum dose 97/103 mg twice daily administered orally.
Other Name: LCZ696 Drug: enalapril matching placebo enalapril matching placebo tablet with minimum dose 2.5 mg, maximum dose 10 mg twice daily administered orally. |
Active Comparator: Enalapril
Initial dose for patients randomized to enalapril were determined by the blood pressure at the time of randomization. Study treatment were titrated to the target dose of enalapril 10 mg bid. Titration were based on blood pressure at the time of the visit. Dose adjustments were only allowed if indicated per protocol defined safety and tolerability criteria and investigator judgement. Patients were required to take a total of two tablets twice daily (one tablet of active enalapril, second from sacubitril and valsartan matching placebo pack) |
Drug: Enalapril
Enalapril tablet with minimum dose 2.5 mg, maximum dose 10 mg twice daily administered orally. Drug: sacubitril/valsartan (LCZ696) matching placebo matching placebo of sacubitril/valsartan (LCZ696) tablet with minimum dose 24/26 mg, maximum dose 97/103 mg twice daily administered orally. |
- N-terminal Pro-brain Natriuretic Peptide (NT-proBNP) Values and Time-averaged Change From Baseline [ Time Frame: Baseline, Week 4 and Week 8 ]
To assess the effect of in-hospital initiation of sacubitril/valsartan vs. enalapril on the time-averaged percentage change of NT-proBNP from baseline in patients who have been stabilized following hospitalization for ADHF and reduced ejection fraction (left ventricular ejection fraction [LVEF] ≤ 40%) between week 4 and 8.
Number of patients with both a baseline value and a value at Week 4 or Week 8. Plasma NT-proBNP (pg/mL) values were averaged from Week 4 and Week 8 visits. N-terminal pro b-type natriuretic peptide (NTproBNP) are peptide (small proteins) that are either hormones or part of the peptide that contained the hormone at one time. They are continually produced in small quantities in the heart and released in larger quantities when the heart senses that it needs to work harder, as in heart failure.
- Number of Patients With Incidences of Symptomatic Hypotension [ Time Frame: 8 weeks of treatment ]Examine the effect of LCZ696 vs. enalapril on incidence of symptomatic hypotension during 8 weeks of treatment Hypotension is low blood pressure. Patients with hypotension may experience symptoms when their blood pressure drops, compared to the patient's normal values. Symptoms of hypotension can include dizziness, lightheadedness, blurred vision, weakness, fatigue, nausea, palpitations, and headache.
- Number of Patients With Incidences of Hyperkalemia [ Time Frame: 8 weeks of treatment ]Hyperkalemia is defined as Potassium level >5.5 mEq/L. Hyperkalemia is the medical term that describes a potassium level in your blood that's higher than normal. Potassium is a chemical that is critical to the function of nerve and muscle cells, including those in your heart.
- Number of Patients With Incidences of Angioedema [ Time Frame: 8 weeks of treatment ]Angioedema is a type of abrupt swelling that occurs under the skin and/or mucous membranes and is often localized to the head, neck, throat, and/or tongue, but may occur elsewhere, including the genitalia and intestines. Severe cases may be associated with difficulty in breathing.
- Change From Baseline in High Sensitivity Troponin (Hs-Troponin) [ Time Frame: Baseline, Week 4/Week 8 ]time-averaged (Weeks 4 and 8) change from baseline in hs-troponin T. hs-Troponin-T is a biomarker that is released from the heart under stress or injury conditions.
- Change From Baseline in Urinary cGMP [ Time Frame: Baseline, Week 4 and Week 8 ]Time-averaged (Weeks 4 and 8) change from baseline in urinary cGMP. Urinary Cyclic GMP (cGMP) is a biomarker measured in the urine that reflects the activity of biomarkers such as BNP (Brain Natriuretic Peptide)
- Change From Baseline in Urinary cGMP to Urinary Creatinine Ratio [ Time Frame: Baseline, Week 4 and Week 8 ]
Time-averaged (Weeks 4 and 8) change from baseline in urinary cGMP to urinary creatinine ratio.
Urinary cGMP to urinary creatinine ratio is how much urinary cGMP (which reflects natriuretic peptide activity) compared to a compound in the urine called creatinine (which helps your doctor evaluate how well your kidneys are functioning).
- Change From Baseline in BNP to NTproBNP Ratio [ Time Frame: baseline, Week 4 and Week 8 ]Time-averaged (Weeks 4 and 8) change from baseline in BNP to NT-proBNP ratio. BNP and NT-proBNP are small proteins produced in large amounts when the heart senses it needs to work harder, such as in heart failure. The test measuring BNP to NT-proBNP is measuring how much of each of these biomarkers are present in order to evaluate heart failure.
- N-terminal Pro-brain Natriuretic Peptide (NT-proBNP) Values and Change From Baseline at Week 8 [ Time Frame: Baseline, Week 8 ]
BNP and NT-proBNP are small proteins produced in large amounts when the heart senses it needs to work harder, such as in heart failure. The test measuring BNP to NT-proBNP is measuring how much of each of these biomarkers are present in order to evaluate heart failure.
Plasma NT-proBNP (pg/mL) values were Week 8 visit.
