Survival of Multiple Arterial Grafting in Diabetic Populations: A 20-Year National Experience

Survival of diabetics after single or multiple coronary artery bypass grafting was compared in a national database over twenty years with 69,224 patients. End points were long-term all-cause mortality and thirty-day clinical outcomes. 17,474 nondiabetic and 10,989 diabetic matched pairs were generated. At a median of 5.9 years after grafting, mortality was statistically significantly lower after multiple arterial grafting in both diabetic and nondiabetic cohorts. The incidence of myocardial infarction was significantly higher in single rather than multiple grafting for both cohorts. Multiple arterial grafting was associated with improved survival for both diabetic and nondiabetic patients.
