ROCHESTER, Minn.--(BUSINESS WIRE)--A team of Mayo Clinic researchers has found that patients with broken heart syndrome, also known as apical ballooning syndrome (ABS), have blood vessels that don’t react normally to stress. These results offer clues to the cause of this rare syndrome and may help with efforts to identify patients who are more vulnerable to mental stress so that appropriate therapies can be developed. The study is published online in the Journal of the American College of Cardiology.
