Brain activity may predict cardiovascular risk
By conducting mental stress tests and monitoring blood pressure and heart rate during an MRI procedure, researchers may have found an activity pattern in the brain that predicts an increased risk for cardiovascular disease, according to proof-of-concept research published August 23 in the Journal of the American Heart Association.
