One hundred patients were enrolled at a large urban university hospital the day prior to their scheduled angiogram. This study was of the relationship between psychosocial factors and coronary artery disease (CAD). The sample consisted of 35 women and 65 men, with a mean age of 57. Subjects completed questionnaires measuring hostility (Cook-Medley Hostility Score), anger-in (Anger Expression (AX) Scale), social desirability (Marlowe-Crowne Social Desirability Scale), anxiety (State Anxiety Scale), and social support (Interpersonal Support Evaluation List). Vessel occlusion was rated using the NUMVES technique, which is a count of vessels occluded $\geq$75%.There were no significant differences between NUMVES groups on hostility or anger-in scores. Anger-in and hostility correlated significantly, but the combination of high hostility with low anger-in versus hostility and high anger-in failed to discriminate NUMVES groups. Social support was significantly, but negatively, related to disease in that high social support was associated with high CAD. With the nondiseased groups removed from the analysis, however, social support was no longer significant. There was significantly more CAD found in caucasians, in men, in patients aged 50-65, and in those with higher education. There were no significant changes in results when analyses were repeated for only the 70 caucasian subjects. While some results may be attributed to specific characteristics of the subjects under study, more investigation of these variables' relationship with CAD is indicated.
