Sildenafil and cardioprotection
Abstract
The phosphodiesterese-5 (PDE5) inhibitors, including sildenafil (Viagra™), vardenafil (Levitra™), tadalafil (Cialis™) and avanafil (Stendra™) have been developed for the treatment of erectile dysfunction. Moreover, sildenafil and tadalafil have been approved for the management of pulmonary arterial hypertension. A number of preclinical studies have shown that PDE5 inhibitors have powerful protective effect against several clinical scenarios including myocardial ischemia/reperfusion injury, doxorubicin and post-MI, heart failure, cardiac hypertrophy, heart transplantation, Duchenne muscular dystrophy and preconditioning of stem cells. Based on these studies, it appears that sildenafil and other PDE5 inhibitors hold promise for further development as novel drug therapies in cardioprotection.
How strong is the evidence?
Evidence Hub reads this as a review, done in animal, not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
