Abstract 15345: Cost-Effectiveness Comparative Study for Clinical, Surgical or Percutaneous Treatment in Patients With Stable Multivessel Coronary Artery Disease: 10 Year Follow-Up

Introduction: The MASS II Study (The Second Medicine, Angioplasty or Surgery Study) included 611 patients with Multivessel Coronary Artery Disease (CAD) and preserved systolic function; these patients underwent coronary artery bypass graft surgery (CABG, n=203), percutaneous coronary intervention (PCI, n=205), and exclusive medical treatment (MT, n=203). This work performed the comparative cost-effectiveness analysis among three groups over the 10 years’ follow-up. Objectives and Methods: Analyze, in a prospective way, the comparative cost of the three therapeutic forms during 10 years of follow-up. To calculate the cost-effectiveness of the final cumulative cost, it was performed adjustment for the mean time free of events and for the proportion of patients free of angina at the end of the period. Results: At the end of ten years, the MT group presented a cumulative cost of US$ 6,183; the PCI group, of US$ 14,292; and the CABG group, a cost of US$ 12,316 (p<0.0001). Costs corrected for event-free surviva...
