Denial of depression as an independent correlate of coronary artery disease.

A number of psychosocial measures were tested as correlates of coronary artery disease (CAD) in 122 males with positive coronary angiograms and 56 males with no manifest history of atherosclerotic disease who were selected to approximate the patients' age and socio economic status. Only denial of depression as indexed by spouse/friend-minus-self scores on the Ketterer Stress Symptom Frequency Checklist and number of unprovoked nocturnal awakenings were independently and positively related to CAD severity in multivariate regression analyses which controlled for jointly associated cardiac risk factors and commonly used cardiovascular medications. Denial of depression and unprovoked nocturnal awakening appear to be independent correlates of coronary artery disease.
