Examination of the Suitability of Vericiguat in Non-Heart Failure with Preserved Ejection Fraction Patients with Improved Ejection Fraction

Abstract

Background/Objectives: Vericiguat has been shown to reduce cardiovascular mortality and hospitalisation for heart failure in patients with reduced ejection fraction. While Vericiguat is considered one of the standard treatments for heart failure, it is unclear under which conditions Vericiguat would be most effective. With a focus on the prognosis and improved EF of heart failure, we aimed to investigate in which cases Vericiguat is suitable for use in addition to standard cardioprotective drugs. Methods: We prospectively compared echocardiograms taken before and after the administration of Vericiguat in 46 patients with non-dialysis and without heart failure with preserved ejection fraction (non-HFpEF) (left ventricle ejection fraction [LVEF] < 50%) who were able to continue Vericiguat in addition to other standard heart failure drugs (the “Fantastic Four”) for more than 6 months at our hospital. Patients who showed an improvement of 10 points or more in LVEF were defined as improved EF+. Results: LVEF improved significantly from 38 [33–45]% at the time of administration to 46 [35–54.5]% at 6 months (p < 0.001). When comparing patients with and without improved EF, a significant difference was observed in the Hb (OR = 1.66, 95%CI = 1.12–2.83, p = 0.028), early introduction (OR = 12.5, 95%CI = 1.58–149, p = 0.025), and initiation of Vericiguat after the administration of the Fantastic Four (OR = 9.79, 95%CI = 1.71–100.2, p = 0.022). Conclusions: In this study, the early administration of Vericiguat, haemoglobin value, and initiation of Vericiguat after the introduction of the Fantastic Four were identified as independent factors for eligibility in non-dialysis, non-HFpEF patients who were able to continue GDMT treatment for more than 6 months after adding Vericiguat.
