Abstract

Phosphodiesterase 5 (PDE5) selectively hydrolyzes cyclic guanosine monophosphate. Inhibitors of PDE5 were originally developed to treat angina pectoris, and currently have multiple therapeutic indications, including erectile dysfunction and pulmonary hypertension. several lines of research have provided evidence to support various potential PDE5-dependent cellular mechanisms in the myocardium that are involved in the pathophysiology of heart failure and cardiac dysfunction. In this Review we provide a mechanistic overview of the pharmacological inhibition of PDE5 in the context of heart failure, and evaluate the evidence supporting the use of novel PDE5 inhibitors in the treatment of this condition.
