Return to work after coronary artery bypass operation

A societal cost-benefit argument has been made for the coronary artery bypass graft (CABG) operation. Most patients experience improvement in symptoms and many can return to a productive livelihood. To estimate the rate of return to work and identify the factors influencing that outcome, we analyzed the work status before and after operation in a follow-up of 105 patients undergoing CABG operations in a new teaching hospital. Overall, relief or improvement in angina was accomplished in 92% of patients, and there was a 10% net increase to th work force after operation. Of all variables studied, preoperative work status was found to be the most statistically significant predictor of the postoperative return to work; other factors associated with return to work included symptomatic relief or improvement, age, and educational level. Preoperative and postoperative means of support did not play a major role in determining work outcome.
