SAN FRANCISCO, March 16 (UPI) -- U.S. researchers say they may have discovered why women who go to emergency rooms with chest pain are often are told their arteries and hearts are fine.
Dr. C. Noel Bairey Merz, professor of medicine and medical director of the Barbra Streisand Women's Heart Center at the Cedars-Sinai Heart Institute and colleagues found emotional stressors -- such as those provoking anger -- might cause changes in the nervous system. These changes in what controls the heart rate also trigger a type of coronary artery dysfunction that occurs more frequently in women than men.
