ROOBY Trial Follow-up Extension

The Department of Veterans Affairs "Randomized On/Off Bypass" (ROOBY) Trial (CSP #517) was funded in 2001. ROOBY was designed to compare the short-term (30-day) and intermediate-term (1-year) outcomes for patients undergoing off-pump versus on-pump coronary artery bypass graft (CABG) procedures. The ROOBY trial reported a significantly higher 1-year adverse composite outcome rate (i.e., all-cause death, non-fatal myocardial infarction (MI) and/or repeat revascularization) for off-pump versus on-pump patients. ROOBY documented that a higher percentage of off-pump patients received fewer grafts than originally planned (i.e., off-pump patients were less completely revascularized) as compared to on-pump patients. Across all anatomic regions of the heart, the 1-year graft patency rates were significantly lower for off-pump CABG patients. Based on these ROOBY trial initial findings, critically important clinical questions related to the long-term efficacy, stability and durability of the off-pump versus on-pump techniques have been raised. Extending the original ROOBY trial, this CSP #517 follow-up study (CSP 517-FS) will evaluate the longer-term impact of off-pump versus on-pump surgical approaches upon the future occurrence of major adverse cardiovascular events (MACE).
