Improvement of Health Status Following Initiation of Sacubitril/Valsartan in Heart Failure and Reduced Ejection Fraction

Abstract

Background: Treatment of heart failure with reduced ejection fraction (EF) may improve patient-reported health outcomes.

Objectives: The purpose of this study was to determine timing and magnitude of change in Kansas City Cardiomyopathy Questionnaire (KCCQ)-23 scores following initiation of sacubitril/valsartan and interaction with change in amino-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations.

Methods: From a single-arm, open-label study of patients initiated on sacubitril/valsartan, KCCQ-23 scores and NT-proBNP were obtained at baseline and follow-up through 12 months. Cross-sectional and longitudinal analyses evaluated magnitude and rate of change in KCCQ-23 scores and associations with NT-proBNP. Patient-level data from the randomized EVALUATE-HF study were used as historic controls.

Results: The analysis cohort (n = 678, age 64.7 years, 71.5% men, EF 28.9%) had a baseline KCCQ-23 overall score (OS) of 65.6. Following sacubitril/valsartan initiation, the majority (n = 412; 60.8%) of participants experienced a rise in KCCQ-23 OS ≥10 points; 26.0% increased by ≥20 points. Comparable improvement in KCCQ-23 scores was seen in various subgroups. Change in KCCQ-23 OS was inversely associated with change in circulating NT-proBNP concentrations. Among a control group of patients in EVALUATE-HF, linear rate of change in KCCQ-12 OS/14-day interval in the enalapril arm was 0.37 points (p = 0.06), whereas in the sacubitril/valsartan arm, scores increased at a rate of 1.19 points (p < 0.001), nearly identical to this dataset (1.08 points; p < 0.001).

Conclusions: Treatment of heart failure with reduced EF with sacubitril/valsartan is associated with rapid and significant improvement in KCCQ-23 scores which was significantly related to change in NT-proBNP.
