Clinical Effects of an Impaired sGC-cGMP Pathway
Oxidative stress and the resulting deficiency in NO can lead to insufficient stimulation of the sGC, decreased production of cGMP , and subsequent cardiovascular dysfunction and HF1,3

The impact of nitrates and PDE5 inhibitors is limited, and they do not directly stimulate sGC

First HF HospitalizationCVD
•Symptomatic hypotension + syncope more common w/ vericiguat•More anemia developed with vericiguat (7.6%) than placebo (5.7%)•SAE were similar: vericiguat (32.8%), placebo (34.8%)•No effects of vericiguaton either electrolytes or renal function•At 12 months, 10 mg target dose achieved: vericiguat (89.2%), placebo (91.4%)
Safety & Tolerability
•Vericiguatwas significantly more effective than placebo in reducing:–The composite endpoint of CV death or HF hospitalization (primary endpoint)–HF hospitalization (first and recurrent)•There was directionally aligned reduction in CV death•No significant change in all-cause mortality•Vericiguatgenerally safe and well tolerated•There was excellent guideline-based HF therapy and patient follow-up
