image: In a study publishing today in the Journal of the American College of Cardiology, researchers investigated long-term survival in patients with type 1 and type 2 diabetes following coronary artery bypass grafting. Patients with type 1 diabetes had more than double the long-term risk of death after the surgery compared with patients without diabetes. The long-term risk of death in patients with type 2 diabetes was only slightly higher than in patients with no diabetes. Patients with type 1 diabetes were more likely than patients with type 2 or without diabetes to have comorbidities such as chronic kidney disease, end-stage renal disease, peripheral vascular disease or heart failure, which are all associated with a worse prognosis in coronary bypass patients with diabetes.
This diagram shows outcomes in 39,235 patients who underwent primary isolated coronary artery bypass grafting in Sweden between 2003 and 2013, according to type of diabetes. Note: Hazard ratios for CV death, non-CV death, and repeat revascularization are subdistribution hazard ratios. Death+MACE is defined as a combined endpoint of death, or rehospitalization for heart attack, heart failure or stroke, or repeat revascularization. CI = confidence interval; CV = cardiovascular; MACE = major adverse cardiac event(s); Ref = reference category.
