The cGMP-dependent protein kinase 1 alpha (PKG1α) opposes pathological left ventricular (LV) hypertrophy and remodeling via roles in the cardiac myocyte (CM) and regulates blood pressure by promoting vascular smooth muscle cell (VSMC) relaxation and vasodilation. Drugs which activate PKG1, including nitrates, sacubitril/valsartan, vericiguat, and others have improved mortality in heart failure with reduced LV ejection fraction (HFrEF) and thus represent a central advance in HFrEF treatment. However, these therapies remain limited by incomplete efficacy in HFrEF. Furthermore, hypotension from PKG1-induced vasodilation has severely limited the practical use of these agents. The overarching…
