On-Pump Versus Off-Pump Coronary Artery Bypass Surgery in Patients With Preoperative Anemia

Anemic off-pump CABG (n=361) versus on-pump CABG (n=578) patients were compared.  In anemic patients, off-pump CABG was associated with lower early morbitidy and mortality. 1 to 6 month follow-up mortality, however, was higher in the off-pump CABG cohort.
