Cardiac Prehabilitation.

The care of patients undergoing cardiac surgery is becoming more complex, in part owing to the increasing burden of comorbid disease, frailty, and psychosocial issues. Many risk factors for postoperative morbidity and mortality are potentially modifiable if identified and treated in a timely fashion before surgery. Cardiac prehabilitation, draws from strategies currently undertaken in cardiac rehabilitation but implements them proactively rather than reactively. There is substantial evidence that in multiple domains, including aerobic conditioning, respiratory muscle training, lifestyle modification, diabetic control, sleep, and psychoeducation, selected interventions before cardiac surgery may improve outcomes. However, the optimal preoperative program remains unclear and there is an unmet need for a comprehensive evaluation of the range of interventions specifically targeted at modifiable perioperative risk factors that may reduce adverse outcomes after cardiac surgery.
