Plasma renin activity as a marker for predicting the antihypertensive effect of switching to sacubitril/valsartan in treated hypertensive patients: Usefulness in daily clinical practice

Abstract

Abstract The authors investigated the antihypertensive effect of sacubitril/valsartan (Sac/Val) when switching from other drugs and assessed whether brain natriuretic peptide (BNP) or plasma renin activity (PRA) before drug switching was a predictor of blood pressure lowering after switching to Sac/Val. In 92 patients with treated hypertension, clinic blood pressure, plasma BNP, and PRA were examined before and after switching to Sac/Val. Clinic systolic and diastolic blood pressures significantly decreased after drug switching to Sac/Val (p < .0001, respectively). The level before drug switching of BNP had no correlation with the change in systolic blood pressure (Δ‐SBP) before and after switching to Sac/Val, but that of PRA was significantly correlated with Δ‐SBP (r = .3807, p = .0002). A multiple regression analysis revealed that PRA before drug switching was an independent determinant of Δ‐SBP. Our findings suggest that low PRA may become a useful marker to predict the antihypertensive effect of switching to Sac/Val in treated hypertensive patients.
