People who have had a coronary artery bypass often develop depression; something which can have a negative impact on their health. Researchers at the University of Pittsburgh School of Medicine studied 302 people who had had a coronary-artery bypass. 150 of the participants received eight months of collaborative care by telephone while the rest made up a control group. The people who received the telephone counselling had improvements in their mental health, physical functioning, moods and levels of depression compared to the other group, with depressed men benefiting more than depressed women; however, a significant minority of patients did not benefit from the intervention.
