Psychological and Behavioral Responses After Coronary Artery Bypass Surgery

One hundred consecutive patients who underwent coronary artery bypass surgery at the Columbia-Presbyterian Medical Center from December 1972 through February 1975 were evaluated at surgery and then followed for as long as 4½ years to study their postoperative psychosocial and behavioral course. One patient died during the first 30 days. At 4½ years, 23 patients were reported as deceased, 15 from cardiac causes. The majority of the long-term survivors had substantially less angina and greater exercise capacity; surgery did not increase the number of patients who were employed, but led to substantial improvements in the quality of life, including general pleasure, reduction of anxiety and depression and subjective improvement in job and family roles. Sexual adjustment improved the least; the frequency of sexual relations tended to decrease. Compliance with the medical regimen was relatively good for smoking and exercise, but not for diet or type A behavior, suggesting a need for psychological intervention.
