This is a 5-year follow-up study of coronary artery by-pass graft (CABG) patients. Our aim was: To study the development of previously rated psycho-medical aspects, with special reference to depression among the CABG patients. The patients were sent two questionnaires, one of which focused on psycho-medical factors and the other on depression. The average rate of participation was 80%. The most important results were that previously high levels of depression were no longer to be found and that post-operative depression among the CABG patients clearly disappears over time.
