Association Between Angiotensin Receptor-Neprilysin Inhibition, Cardiovascular Biomarkers, and Cardiac Remodeling in Heart Failure With Reduced Ejection Fraction.

Journal Article (Journal Article)

BACKGROUND: Sacubitril/valsartan (S/V) treatment is associated with reverse cardiac remodeling and reductions in biomarkers reflecting ventricular wall stress and myocardial injury, such as NT-proBNP (N-terminal pro-B-type natriuretic peptide), hs-cTnT (high-sensitivity cardiac troponin T), and soluble suppressor of tumorigenicity 2 (sST2). How longitudinal changes in these biomarkers analyzed collectively are associated with cardiac remodeling in patients with heart failure with reduced ejection fraction treated with S/V is uncertain. METHODS: In a prospective study of S/V in patients with heart failure with reduced ejection fraction, this prespecified exploratory analysis included patients with serially collected biomarkers and echocardiographic measures of cardiac remodeling through 12 months of treatment. A multivariate latent growth curve model assessed associations between simultaneous changes in biomarkers and left ventricular ejection fraction and left atrial volume index. RESULTS: Seven hundred fifteen out of 794 total study participants were included (mean age 65 years, 73% male). Mean baseline left ventricular ejection fraction and left atrial volume index were 29% and 40 mL/m2, respectively. Adjusted geometric mean baseline concentrations for biomarkers included NT-proBNP of 649 pg/mL, hs-cTnT of 15.9 ng/L, and sST2 of 24.7 ng/mL. Following initiation of S/V, circulating concentrations of NT-proBNP, hs-cTnT, and sST2 significantly decreased within 30 days and remained significantly different than baseline at all subsequent timepoints. From baseline to month 12, decreases in adjusted biomarker concentrations averaged -27.9% (95% CI, -35.1% to -20.7%; P<0.001) for NT-proBNP; -6.7% (95% CI, -8.8% to -4.7%; P<0.001) for hs-cTnT; and -1.6% (95% CI, -2.9% to -0.4%; P<0.001) for sST2. NT-proBNP concentrations were predictive of later changes in hs-cTnT. The magnitude of reductions in NT-proBNP and hs-cTnT concentrations associated with improvements in left ventricular ejection fraction and left atrial volume index. There was no association between changes in sST2 and changes in other measures. CONCLUSIONS: Following initiation of S/V, NT-proBNP, hs-cTnT, and sST2 concentrations decreased significantly. Longitudinal changes in NT-proBNP and hs-cTnT together associated with left atrial and left ventricular reverse remodeling.
