Clinical and economic impact of diabetes mellitus on percutaneous and surgical treatment of multivessel coronary disease

ABSTRACT

Our aims were to compare coronary artery bypass grafting (CABG) and stenting for the treatment of diabetic patients with multivessel coronary disease enrolled in the Arterial Revascularization Therapy Study (ARTS) trial and to determine the costs of these 2 treatment strategies.Patients (N= 1205) were randomly assigned to stent implantation (n= 600; diabetic, 112) or CABG (n=605; diabetic, 96). Costs per patient were calculated as the product of each patient's useof resources and the corresponding unit costs.Baseline charcteristics were similar between the groups. At 1 year , diabetic patient treated with stenting had the lowest event-free survival rate (63,4%) because of a higher incidence of repeat revascularization compared with both diabetics patients...
