Your query inspired me to use a similar query to OpenEvidence, which is primarily medically oriented. I use sildenafil because I am a fan of it. It was the one used in studies and has a shorter half-life, so dosing is less problematic. The bold highlight is mine.
Does daily sildenafil consumption reduce all-cause mortality in males?
"Expanded question: Does daily sildenafil consumption reduce all-cause mortality in males, specifically in those with conditions like pulmonary arterial hypertension or chronic heart failure?
Yes, daily sildenafil consumption can reduce all-cause mortality in males with conditions like pulmonary arterial hypertension (PAH) or chronic heart failure (CHF).
For patients with PAH, several studies have demonstrated that sildenafil therapy is associated with improved survival rates. For instance, a study by Zeng et al. found that the 1-, 2-, and 3-year survival rates in the sildenafil group were significantly higher compared to the conventional treatment group (88%, 72%, and 68% vs. 61%, 36%, and 27%, respectively).[1] Additionally, a randomized, multicenter study published in Circulation showed that higher doses of sildenafil (80 mg TID) were noninferior to lower doses (5 mg TID) in terms of all-cause mortality, with a hazard ratio of 0.51, indicating a potential survival benefit.[2]
In the context of chronic heart failure, the evidence is more mixed. While sildenafil has been shown to improve exercise capacity and hemodynamic parameters in patients with heart failure and secondary pulmonary hypertension, its impact on mortality is less clear. A meta-analysis by Zhuang et al. indicated that sildenafil improved hemodynamic parameters and exercise capacity in heart failure patients, particularly those with reduced ejection fraction, but did not show a significant impact on all-cause mortality.[3]
In summary, sildenafil can reduce all-cause mortality in males with PAH, but its effect on mortality in chronic heart failure patients is less definitive and requires further investigation. Always consult with a healthcare provider for personalized medical advice.
