ABSTRACT
BACKGROUND:
The effect of vericiguat on sequential N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and influence of this relationship on clinical outcomes is unknown.OBJECTIVES:
This study assessed the relationship between changes in NT-proBNP and the primary outcome (cardiovascular death or heart failure hospitalization); evaluated the effect of vericiguat on changes in NT-proBNP; and explored the association between the efficacy of vericiguat and changes in NT-proBNP.METHODS:
NT-proBNP was measured at randomization and at 16, 32, 48, and 96 weeks in 4,805 of 5,050 patients. The association between NT-proBNP change at week 16 and the primary outcome was assessed. The relationship between changes in NT-proBNP and the primary outcome according to treatment group was assessed by using joint modeling and mediation analysis.RESULTS:
A significant and sustained decline in NT-proBNP levels was seen in both treatment groups. After week 16, NT-proBNP levels decreased more with vericiguat vs placebo (any reduction odds ratio [OR] 1.45 [95% CI 1.28-1.65]; P < 0.001; ≥50% reduction OR 1.27 [95% CI 1.10-1.47]; P = 0.001) and were less likely to increase (≥20% increase OR 0.68 [95% CI 0.59-0.78]; P < 0.001; ≥50% increase OR 0.70 [95% CI 0.59-0.82]; P < 0.001). The treatment effect related to serial NT-proBNP on the primary composite outcome was HR 0.96 (95% CI 0.95-0.99) at week 16, which increased to HR 0.90 (95% CI 0.85-0.96) at week 48; the average extent of mediation of the composite outcome related to NT-proBNP was 45%.CONCLUSIONS:
In patients with worsening HFrEF, vericiguat significantly decreased NT-proBNP levels compared with placebo. This change appeared associated with a modest relative improvement in the primary outcome of cardiovascular death or heart failure hospitalization.
