Use of soluble guanylyl cyclase stimulators in heart failure therapy—a mode of action perspective

Year: 2026

Type: article

Abstract: Despite recent advances in pharmacological treatment, chronic heart failure (HF) is associated with significant morbidity and mortality, and further treatment options are needed. Intact nitric oxide (NO)-soluble guanylyl cyclase (sGC)-cyclic guanosine monophosphate (cGMP) signalling is a prerequisite of cardiovascular health. cGMP produced by NO/NO-sGC acts as a second messenger molecule via various downstream targets, which influence a broad spectrum of critical physiological parameters. Impairment of this cascade in the cardiovascular system is considered an important pathomechanism in HF. This review examines pharmacological therapies that act through the NO-sGC-cGMP signalling pathway. We will focus on the molecular mode(s) of action of NO-independent but haem-dependent sGC stimulators, and will examine evidence from preclinical studies demonstrating cardiovascular benefits of these therapies and their increasing number of effects on other susceptible tissues and organs, which together could contribute to clinical outcomes in HF. The sGC stimulator vericiguat may be considered, in addition to standard therapy, for adults with symptomatic HF with reduced ejection fraction following a worsening event. The findings from pivotal clinical trials that led to these recommendations will be outlined and classified in terms of their significance for different subpopulations. These include the Phase 3 VICTORIA and VICTOR trials. Finally, further research areas and ongoing studies designed to address existing gaps in our knowledge regarding vericiguat and related drugs will be highlighted.
