Newswise — Long Beach, Calif. (April 5, 2024)—Microvascular function is lower in Black men following a recent diagnosis of prostate cancer, compared to white men, according to researchers at the Medical College of Georgia. Researchers will present their work this week at the American Physiology Summit, the flagship annual meeting of the American Physiological Society (APS), in Long Beach, California.  

It is widely documented that racial disparities exist in prostate cancer outcomes. The purpose of this study was to comprehensively assess vascular health in Black and white men who were within three months of prostate cancer diagnosis. In this case, researchers examined 28 men who were newly diagnosed with prostate cancer (10 white and 18 Black). They evaluated vascular health by measuring large blood vessel function (brachial artery dilation), small blood vessel function (microvascular blood flow) and arterial stiffness. The researchers determined Black men had significantly lower microvascular function compared with their white counterparts. Impaired microvascular function …
