Abstract
Psychological distress has been associated with the pathogenesis and progression of coronary heart disease (CHD) but little is known about the determinants of distress as a coronary risk factor. Although it has become unfashionable to focus on personality factors since research on Type A behaviour yielded inconsistent findings, personality may comprise a major explanatory factor of individual differences in stress-related CHD. This article focuses on Type D--the distressed--personality, which describes patients who experience increased negative emotions and tend to inhibit the expression of these emotions in social interactions. The article reviews research on Type D personality in the context of CHD. Accumulating evidence indicates that cardiac patients with the Type D personality are at increased risk for cardiovascular morbidity and mortality (odds ratios ranging from 4.1-8.9, P<0.0001) independent of standard cardiac risk factors. Type D patients are also at increased risk for psychological distress, clustering of psychosocial risk factors, impaired quality of life, and seem to benefit less from medical and invasive treatment. Preliminary evidence suggests that physiological hyper-reactivity and activation of pro-inflammatory cytokines may be responsible for the detrimental effect of Type D personality on cardiac prognosis. There is an urgent need to adopt a personality approach in the identification of patients at risk for stress-related cardiac events. Type D is a stable personality construct that may be of special interest not only in CHD, but in other chronic cardiac conditions as well.Keywords
