Abstract | BACKGROUND: AIM: To determine the efficacy and safety of sGC stimulators in HF patients. METHODS: Multiple databases were searched to identify relevant randomized controlled trials (RCTs). Data on the safety and efficacy of sGC stimulators were compared using relative risk ratio (RR) on a random effect model. RESULTS: Six RCTs, comprising 5604 patients (2801 in sGC stimulator group and 2803 placebo group) were included. The primary endpoint (a composite of cardiovascular mortality and first HF-related hospitalization) was significantly reduced in patients receiving sGC stimulators compared to placebo [RR 0.92, 95% confidence interval (CI): 0.85-0.99, P = 0.02]. The incidence of total HF-related hospitalizations were also lower in sGC group (RR 0.91, 95%CI: 0.86-0.96, P = 0.0009), however, sGC stimulators had no impact on all-cause mortality (RR 0.96, 95%CI: 0.86-1.07, P = 0.45) or cardiovascular mortality (RR 0.94, 95%CI: 0.83-1.06, P = 0.29). The overall safety endpoint (a composite of hypotension and syncope) was also similar between the two groups (RR 1.50, 95%CI: 0.93-2.42, P = 0.10). By contrast, a stratified subgroup analysis adjusted by type of sGC stimulator and HF ( vericiguat vs riociguat and HFrEF vs HFpEF) showed near identical rates for all safety and efficacy endpoints between the two groups at a mean follow-up of 19 wk. For the primary composite endpoint, the number needed to treat was 35, the number needed to harm was 44. CONCLUSION: The use of vericiguat and riociguat in conjunction with standard HF therapy, shows no benefit in terms of decreasing HF-related hospitalizations or mortality.
