OBJECTIVES: This prospective cohort study of patients with coronary artery disease (CAD) sought to determine the impact of social support, anger expression and cynical hostility on progression of coronary atherosclerosis as shown by angiography.
BACKGROUND: Low social support, high levels of expressed anger and cynical hostility are correlated to increased CAD morbidity and mortality. However, the impact of these factors, alone or together, on progression of human coronary atherosclerosis is unknown.
METHODS: Of 223 patients with CAD documented by standardized angiography at baseline, 162 had a second angiogram after two years. An expert panel who had no knowledge of the patients' characteristics evaluated the films pairwise to determine disease progression. At baseline, all patients were asked to answer three self-report questionnaires: questions concerning emotional social support, the State-Trait-Anger-Expression Inventory (STAXI) and the Cook-Medley cynical hostility scale. Each patient's clinical and laboratory status was followed.
RESULTS: Questionnaires and angiographic follow-up data were available for 150 patients. Bivariate analysis of the psychological variables showed a higher risk of progression only for patients who scored high on STAXI anger-out or low on social support. In the multivariate analysis, when adjusting for confounding variables and examining the interaction between psychological variables, only patients with both high anger-out and low social support were at highly increased risk for progression (odds ratio 30, confidence interval [CI] 5.5 to 165.1; RR 3.19).
CONCLUSIONS: Patients with CAD and low emotional social support who express anger outwardly are at a highly increased risk of disease progression, independent of medication or other risk factors.
