Hostility and anger-expression style are personality traits often associated with elevated cardiovascular reactivity and potential heightened risk for cardiovascular disease. In the present study a sample of 50 young, healthy men were divided into groups low or high on the Cook-Medley Hostility scale and on anger-out from Spielberger's Anger Expression scale. Subjects worked on mental arithmetic and public speaking tasks in counterbalanced order. Heart rate, systolic and diastolic blood pressure and hemodynamic indices were measured at baseline and during the tasks. Hostility and anger-out interacted in their effects on cardiovascular responses. The High Anger-Out/Low-Hostile group displayed the greatest increases in heart rate and blood pressures, while the High Anger-Out/High-Hostile group was least reactive. Furthermore, the High Anger-Out/Low-Hostile group showed a distinct fight/flight decrease in systemic vascular resistance. These results suggest that a mismatch between hostile cognitions and habitual anger expression leads to greater cardiovascular reactivity to challenging tasks, potentially enhancing risk for development of cardiovascular diseases.
