Personality Type and Heart Disease Risk: Two Have Greater Risk
Researchers have often linked heart disease risk to one of two personality types – Type A or Type B. But there are also two lesser known types, C and D, the latter of which is emerging as a greater risk factor for heart-related problems than Type A’s.
Type A and Type D Personalities At Greater Risk for Heart Disease
The Type A and Type B personality theory was introduced by cardiologists Meyer Friedman and RH Rosenman in the 1950’s to describe a pattern of behaviors thought to be risk factors for coronary heart disease. Type A individuals are impatient (sometimes hostile), highly competitive, controlling, aggressive and have difficulty relaxing. Type B personalities, in contrast, are patient, relaxed and easy going.
Drs. Friedman and Rosenman found, after a nine-year study of healthy men aged 35-59, that Type A personalities have double the risk of coronary heart disease.
