Racial and Ethnic Differences in Biomarkers, Health Status, and Cardiac Remodeling in Patients With Heart Failure With Reduced Ejection Fraction Treated With Sacubitril/Valsartan

Abstract

Background: Among patients with heart failure and reduced ejection fraction (left ventricular (LV) ejection fraction ≤40%), sacubitril/valsartan (S/V) treatment is associated with improved health status and reverse cardiac remodeling. Data regarding racial and ethnic differences in response to S/V are lacking.

Methods: This was an analysis from the PROVE-HF study (Prospective Study of Biomarkers, Symptom Improvement and Ventricular Remodeling During Entresto Therapy for Heart Failure). Longitudinal changes in NT-proBNP (N-terminal pro-B-type natriuretic peptide), cardiac reverse remodeling, and health status scores were compared between groups using multivariate latent growth curve modeling.

Results: Among the 782 patients included in this study, 22.7% were non-Hispanic Black (from here referred to as Black), 14.9% were Hispanic, and 62.4% were non-Hispanic White (from here referred to as White). At baseline, compared with White patients, Black and Hispanic patients had lower NT-proBNP (g=0.34) and differences between groups in baseline values for LV end-diastolic volume index and LV end-systolic volume index were negligible (g<0.10). Following S/V initiation, NT-proBNP decreased in all 3 groups (P<0.0001) associated with improvements in LV ejection fraction, LV end-diastolic volume index, and LV end-systolic volume index. Although total improvement in LV measures was similar between groups, Black patients averaged larger gains in the first half of the trial while White patients averaged larger gains in the second half. Improvements in Kansas City Cardiomyopathy Questionnaire-23 Total Symptom scores were seen in all 3 groups. Treatment with S/V was well-tolerated.

Conclusions: Among Black, Hispanic, and White patients with heart failure and reduced ejection fraction, treatment with S/V was associated with similar reduction in NT-proBNP, improvement in health status, and reverse remodeling. More data regarding racial and ethnic responses to heart failure and reduced ejection fraction treatment are needed.
