OBJECTIVE: To determine the feasibility of a cardiac prehabilitation (Prehab)
program for patients waiting for elective coronary artery bypass graft (CABG).
DESIGN: A two-group parallel randomized controlled trial. SETTING: Medical
fitness facility. SUBJECTS: Seventeen preoperative elective CABG surgery patients
were randomized to standard care (n = 9) or Prehab (n = 8). INTERVENTION:
Standard care: three-hour preassessment appointment. Prehab: exercise and
education classes for 60 minutes/day, twice weekly for at least four weeks. MAIN
MEASURES: Data were collected at baseline, one week preoperatively, and three
months postoperatively. The primary outcome measure was walking distance using a
6-minute walk test. Secondary outcome variables included 5-meter gait speed, and
cardiac rehabilitation attendance three months postoperatively. RESULTS: Fifteen
patients (standard care, n = 7; Prehab, n = 8) completed the study. No Prehab
patients developed cardiac symptoms during study participation. Walking distance
remained unchanged in the standard care group; whereas, the Prehab group
increased their walking distance to mean +/- SD 474 +/-101 and 487 +/-106 m at
the preoperative and three month postoperative assessments (p < 0.05). Gait speed
was unchanged in the standard care group, but improved in the Prehab group by 27%
and 33% preoperatively and three months postoperatively, respectively (p < 0.05).
Enrollment in cardiac rehabilitation three months postoperatively was higher for
Prehab participants (100%) than standard care participants (43%; p < 0.05).
CONCLUSION: These data provide evidence for the feasibility of a Prehab
intervention to improve the health status of patients waiting for elective CABG
surgery. A larger trial of 92 patients will be utilized to demonstrate the safety
and efficacy of Prehab.
