To the Editor: Dr Van Dijk and colleagues1 found no difference in 12-month cognitive outcomes between patients who underwent either on-pump or off-pump coronary artery bypass grafting (CABG). Although the authors alluded to a possible role of microemboli, they did not provide an explanation for the disturbing frequency and permanency of memory loss and dementia following CABG.
