For men, erectile dysfunction may be a predictor of heart disease.
For men, many of the common risk factors for heart disease — such as high blood pressure, obesity, metabolic syndrome, and smoking — are the same as the risk factors for erectile dysfunction, which is a condition that affects as many as 25 percent of all men under the age of 40.
Despite these commonalities, erectile dysfunction has never been studied as an independent risk factor for heart disease in men.
But now, researchers led by Dr. Michael Blaha — an associate professor of medicine at the Johns Hopkins School of Medicine in Baltimore, MD — set out to fill this gap in research by investigating the link between erectile dysfunction and heart health in more than 1,900 men over a period of 4 years.
Their findings were published in the journal Circulation.
Erectile dysfunction predicts heart disease
The researchers examined data extracted from the Multi-Ethnic Study of Atherosclerosis, which is "an ethnically diverse, community-based, multisite prospective cohort study" that encompassed 1,914 study participants aged 60–78.
Overall, the study found that erectile dysfunction puts men at double the risk of cardiovascular problems such as heart attack, cardiac arrest, sudden cardiac death, or stroke.
The scientists say that their study provides the most reliable evidence yet that erectile dysfunction is a stand-alone risk factor for heart disease.
Before other risk factors were considered, the analysis revealed that more than 6 percent of the men with erectile dysfunction experienced these heart problems, whereas these forms of heart disease affected only 2.6 percent of the men who did not have sexual dysfunctions.
After additional risk factors were taken into account, the risk remained almost twice as high for men with erectile dysfunction.
Dr. Blaha comments on the findings, saying, "Our results reveal that erectile dysfunction is, in and of itself, a potent predictor of cardiovascular risk."
"Our findings suggest that clinicians should perform further targeted screening in men with erectile dysfunction, regardless of other cardiac risk factors and should consider managing any other risk factors — such as high blood pressure or cholesterol — that much more aggressively."

He adds that most men try to avoid seeing their physician when they have early symptoms of heart disease, but they do seek help immediately when confronted with erectile dysfunction.
"This is a wonderful opportunity to identify otherwise undetected high-risk cases," says Dr. Blaha.
"The onset of [erectile dysfunction]," he adds, "should prompt men to seek comprehensive cardiovascular risk evaluation from a preventive cardiologist."
