Israeli researchers have found that fear and heart disease are linked. Their study, which involved 1153 healthy men and women, compared fear of terror attacks with levels of C-reactive protein. The protein is a strong predictor of atherosclerosis and other cardiovascular diseases. The results showed that fear of terror almost doubled the risk of high C-reactive protein among the women.

Lead researcher Samuel Melamed, PhD, concluded, "This study demonstrates for the first time, in a sample of apparently healthy workers, that the psychological reaction of chronic fear of terror has a negative impact on health in women." (The findings were reported in Psychosomatic Medicine, July/August 2004.)
