Changes in health-related quality of life in off-pump versus on-pump cardiac surgery: Veterans Affairs Randomized On/Off Bypass trial.

Journal Article (Journal Article)


The relative benefits of performing coronary artery bypass graft surgery off-pump versus on-pump continue to be debated. A critical, patient-centered outcome is health-related quality of life; yet there has been limited evaluation in large-scale, multicenter trials of the off-pump versus on-pump impact upon quality of life.


The Veterans Affairs Randomized On/Off Bypass trial randomized 2,203 nonemergent patients to off-pump or on-pump from February 2002 to May 2007. Patients completed a general quality of life survey (VR-36) and a disease-specific quality of life survey, the Seattle Angina Questionnaire (SAQ), prior to surgery, then again at 3 and 12 months post-bypass.


Of the 2,130 1-year survivors, 1,805 patients (85%) completed 1-year surveys. Randomization resulted in comparable baseline patient characteristics, including VR-36 and SAQ scores. At 3 months and 1-year post-procedure, there were no clinically relevant differences between off-pump and on-pump patients in any of the quality of life measures. Both groups had statistically significant, comparable improvements in the physical component scale of the VR-36, and in the SAQ scales.


For this trial's male, low-to-moderate risk, veteran population, there were no significant differences between off-pump and on-pump with regard to 1-year general and disease-specific quality of life outcomes. Both treatment arms experienced some improvements by 3 months, with continued improvements through 1-year post-bypass.
