What risks are associated with coronary artery bypass grafting in dialysis patients?
A 2000 study by Liu et al. found that dialysis patients undergoing coronary artery bypass grafting have an increased risk of morbidity and mortality compared to those without dialysis. The study, which was part of the Northern New England Cardiovascular Disease Study Group, also found that the risk of death was higher among those who had larger grafts in the coronary artery bypass grafting procedure. Furthermore, the United States Renal Data System's 2009 Annual Data Report found that dialysis patients who undergo coronary artery bypass grafting are also at risk of developing cardiac complications, such as atrial fibrillation, congestive heart failure, and stroke.
