Questions remain
Asked to comment on the study, John Larry, MD, medical director of cardiology and cardiac rehabilitation at the Ohio State University Wexner Medical Center East Hospital, Columbus, said: “For those under time pressure to return to work, [early CR] could be an advantage to allow more rehab time and improved stamina prior to their return-to-work date.”
That said, he noted, “we typically delay any significant upper-body training activities for 8-10 weeks to avoid impact on healing of the sternum. Thus ... starting sooner would limit the amount of time a patient would have to engage in any upper-body resistance training. Many lose upper body strength after surgery, so this is an important part of the recovery/rehab process.”
Matthew Tomey, MD, director of the cardiac intensive care unit, Mount Sinai Morningside, New York, advised “caution” when interpreting the findings, stating that “there was no evident difference in the primary outcome measure of functional capacity by 14 weeks, and the trial was not designed to directly assess impact on either social functioning or economic productivity.”
“I would be interested to [see] more comprehensive data on safety in a larger, more diverse sample of postoperative patients,” he said, “as well as evidence to indicate clear advantage of an earlier start for patient-centered outcomes specifically after cardiac surgery.
“Perhaps the greatest challenges to full realization of the benefits of CR in practice have been gaps in referral and gaps in enrollment,” he added. “It is incumbent upon us as clinicians to counsel our patients and to provide appropriate referrals.”
The study was supported by the Medical and Life Sciences Research Fund and the Jeremy Pilcher Memorial Fund. No conflicts of interest were reported.
