About

Low levels of physical fitness increase the risk of death in patients with cardiovascular disease. Although cardiac rehabilitation programs improve the health of patients after heart surgery, most patients are not referred until after surgery. Therefore, the purpose of this study was to determine if an exercise "pre-habilitation" (i.e., Prehab) program before heart surgery would improve the health of patients before surgery and whether these improvements would be maintained after surgery.

The investigators hypothesized that Prehab would promote the health of patients before heart surgery, and these improvements would be maintained three months post-operatively, as compared to patients who received standard care.

Full description

This was a single-centre, parallel randomized controlled trial conducted in Canada to determine the feasibility and efficacy of an exercise and education "pre-habilitation" (i.e., Prehab) program before elective coronary artery bypass graft surgery (CABG). We recruited 17 patients who were scheduled to undergo elective CABG surgery from February 2011-May 2012. Enrolled patients were assessed at baseline, one week pre-operatively, and three months post-operatively.

Enrollment: 17 patients

Sex: All

Ages: 18 to 99 years old

Volunteers: No Healthy Volunteers

• No history of myocardial infarction within the past 7 days
• Ejection fraction greater than 30%
• No history of dementia or psychiatric problems
• No self-reported dizziness or confusion

Exclusion criteria

• If patients cannot attend Prehab due to geographical limitations
