Simple Test Predicts Blood Vessel Disease Linked to Erectile Dysfunction

Peripheral arterial tonometry (PAT) is a simple and inexpensive test that measures the health of blood vessels. A sensor worn on the finger measures changes in finger volume that occur during each pulse wave (heartbeat). The test is a marker of the function of the endothelial cells lining the arteries. Poor endothelial function is linked to erectile dysfunction in men and poor sexual function in women. Jason Kovac from the Baylor College of Medicine and coworkers found that PAT is a useful, noninvasive technique for assessing erectile dysfunction due to poor blood vessel health. Erectile dysfunction and blood vessel function are important predictors of cardiovascular disease, heart attack and stroke. PAT is a simple test that could identify people at risk for serious cardiovascular events. (International Journal of Impotence Research, 26: 218-222, 2014)
