What is the risk of morbidity and mortality for elderly patients undergoing CABG compared to younger subjects?
Elderly patients (defined as 80 years or older) undergoing CABG are more likely to have severe (left main or multi-vessel) CAD, LV systolic dysfunction, concomitant valvular disease, and previous sternotomy. In addition, they often have comorbid conditions, such as diabetes mellitus, hypertension, chronic obstructive pulmonary disease, PAD, and azotemia. As a result, the elderly have a higher perioperative risk of morbidity and mortality than do younger patients receiving CABG.
