Because men with erectile dysfunction (ED) share the same modifiable risk factors as those with coronary artery disease (CAD), it has been suggested that lifestyle interventions to reduce cardiovascular (CV) risk factors in patients with ED may improve their symptoms and contribute to the maintenance of sexual function, according to a U.S. meta-analysis of studies published online September 12 in Arch Intern Med. A U.S. meta-analysis study published online Sept. 12 in Arch Intern Med provides further evidence for this idea. Researchers searched multiple electronic databases to include randomized, controlled studies on the reduction of CV risk factors through lifestyle interventions or medications with at least 6 weeks of follow-up. Ultimately, 740 patients from 4 countries and 6 studies were identified for enrollment. The results showed that reducing CV risk factors through lifestyle changes and medication was significantly associated with improved sexual function in patients. If studies involving statin interventions (143 cases) were excluded, the remaining 4 studies on lifestyle modification interventions (597 cases) also demonstrated that this intervention method was significantly associated with improved sexual function.
