November 26, 2014 — Men who have asymptomatic subclinical vascular disease are more likely to develop erectile dysfunction than men who don’t have early stage vascular disease, according to research presented at the American Heart Association’s Scientific Sessions 2014. Data suggests use of a coronary computed tomography (CT) calcium exam may reveal the patient’s risk of developing erectile dysfunction.
“Erectile function can be a window into men’s cardiovascular and overall health,” said David I. Feldman, B.S., lead author and research assistant at the Ciccarone Center for the Prevention of Heart Disease at Johns Hopkins in Baltimore, Maryland. “Erectile dysfunction and cardiovascular disease commonly coexist.”
Researchers studied 1,862 men without existing heart disease and assessed the relationship between early atherosclerotic plaque development and arterial stiffness and dysfunction with their subsequent self-reporting of erectile dysfunction.
Researchers found:
- Men with coronary artery calcium scores greater than 100 Agatston units were 43 percent more likely to later self-report erectile dysfunction compared to otherwise identical men with normal calcium scores. (The Agatston Score is a measure of the amount of calcified plaque in the coronary arteries.)
- Men who subsequently had erectile dysfunction were at least two times more likely to have coronary artery calcium scores greater than 100 Agatston units at the start of the more than nine-year study.
- While coronary artery calcium had the strongest association to erectile dysfunction, other measures of early vascular disease, including carotid intima-media thickness (cIMT), were notably worse among men with erectile dysfunction compared to those without. cIMT measures plaque build-up in your carotid arteries that supply blood to the head, neck, and brain.
- After considering age, race, sex and traditional risk factors — such as diabetes, smoking, high cholesterol and obesity — men with abnormalities of both atherosclerosis as well arterial stiffness and dysfunction were 53 percent more likely to later self-report erectile dysfunction.
More research is needed before physicians routinely use coronary artery calcium tests over other noninvasive methods to assess men’s sexual health, Feldman said. And more work needs to be done on how best to prevent erectile dysfunction in those men with confirmed asymptomatic vascular disease.
Researchers excluded men on impotence drugs and couldn’t ensure that all men
