Abstract

Two studies assess relationships of hostility to extent and severity of exercise-induced cardiac ischemia and daily life ischemia in patients with coronary artery disease (CAD). CAD patients (N = 80) who underwent exercise tomographic thallium testing to assess myocardial perfusion completed the Cook-Medley Hostility Inventory (Ho). A Composite Hostility (Chost) score obtained from the Ho scale was also used. Statistically controlling for the effects of gender in the full sample (N = 80), Chost was positively correlated with severity of perfusion defects (r = 0.22, p < 0.05). This relationship was nonsignificant in the 63 male patients, but was significant among women (N = 17, r = 0.42, p < 0.05) and among middle-aged men (less than 60 years, N = 17, r = 0.55, p < 0.05). In an overlapping sample of 42 CAD patients with ischemia (ST-segment depression ≥1 mm) during 24 to 48 hours of ambulatory electrocardiographic monitoring, after controlling for gender, both Ho and Chost were positively correlated with total minutes of ischemia (r = 0.28 and r = 0.29, respectively, p < 0.05). In addition, there was a significant gender x hostility interaction, with stronger relationships with hostility evident for women. Results from these two studies indicate that in patients with coronary artery disease, hostility traits are significantly correlated with extent of daily life ischemia and with severity of exercise- induced myocardial ischemia. These relationships appear to be significant among female and middle aged male patients, but may be less evident among older male patients.
