Connerney, I. Relation between depression after coronary artery bypass surgery and 12-month outcome: a prospective study. The Lancet , 358, 1766-1771.

Many studies exist which have found an association between depression and cardiac events and mortality related to them. But, it is also important to find out if presence of depression has a negative impact on the outcome of patients undergoing coronary artery bypass surgery.

This study is a prospective study which was conducted on 309 patients who underwent CABG and were followed for a period of one year. It was found that 20% of the patients had depression at the time of discharge from the hospital and at follow up after one year, cardiac events were noted in a significantly higher proportion of depressed individuals as compared to individuals who were not depressed. Thus, this study clearly establishes the fact that depression is an independent outcome predictor after bypass surgery and affects the course of these patients drastically. Therefore, it is important to screen patients for depression after CABG and treat them adequately to improve outcomes after surgery.
