What are the effects of mood disturbance and anxiety on CABG outcomes?
Depression is an important risk factor for the development and progression of CAD, and it is a more important predictor of the success of cardiac rehabilitation than many other functional cardiac variables. Preoperative anxiety is associated with significantly increased risk of death, while preoperative depression is not. Severe depression before and 6 months after CABG is associated with increased risk of death, as is mild or moderate depression that persists at 6 months. Finally, depression after CABG is an important predictor of the recurrence of angina during the first 5 postoperative years.
