ROCHESTER, Minn. — A Mayo Clinic-led study involving 488 cardiac patients whose cases were followed for up to 12 years finds that microvascular endothelial dysfunction, a common early sign of cardiovascular disease, is associated with a greater than twofold risk of cancer.
The study, published in the European Journal of Preventive Cardiology, finds that microvascular endothelial dysfunction may be a useful marker for predicting risk of solid-tumor cancer, in addition to its known ability to predict more advanced cardiovascular disease, says Amir Lerman, M.D., a Mayo Clinic cardiologist and the study’s senior author.
“The study demonstrated that noninvasive vascular function assessment may predict the future development of cancer,” says Lerman, who is director of cardiovascular research at Mayo Clinic. “More studies are needed, but assessment of vascular function potentially may predict individuals at risk.”
Microvascular endothelial dysfunction involves damage to the walls of small arteries in the heart, which affects their ability to expand and limits the flow of oxygen-rich blood. Hypertension, high cholesterol, obesity and diabetes are among the causes, and symptoms of dysfunction include chest pain. The condition is treatable but difficult to detect.
