Is Worrying Bad for Your Heart?

Abstract
Background Worry is an important component of anxiety, which recent work suggests is related to increased incidence of coronary heart disease (CHD). Chronic worry has also been associated with decreased heart rate variability. We hypothesized that high levels of worry may increase CHD risk. Method and Results We examined prospectively the relationship of worry with CHD incidence in the Normative Aging Study, an ongoing cohort of older men. In 1975, 1759 men free of diagnosed CHD completed a Worries Scale, indicating the extent to which they worried about each of five worry domains: social conditions, health, financial, self-definition, and aging. During 20 years of follow-up, 323 cases of incident CHD occurred: 113 cases of nonfatal myocardial infarction (MI); 86 cases of fatal CHD; and 124 cases of angina pectoris. Worry about social conditions was the domain most strongly associated with incident CHD. Compared with men reporting the lowest levels of social conditions worry, men reporting the highest lev...
