Cost-Effectiveness of Coronary Stenting and Abciximab for Patients With Acute Myocardial Infarction

2003 
Background— Both stenting and the glycoprotein IIb/IIIa inhibitor abciximab improve outcomes for patients undergoing primary angioplasty for acute myocardial infarction (AMI). However, the cost-effectiveness of these strategies is unknown. Methods and Results— We performed a prospective cost-utility analysis among US participants in the CADILLAC trial. Patients with AMI (n=1703) were randomized to stenting versus balloon angioplasty (PTCA) and abciximab versus no abciximab according to a 2-by-2 factorial design. Total 1-year costs and lifetime incremental cost-effectiveness ratios, measured as cost per quality-adjusted year of life (QALY) gained, were calculated. Compared with PTCA, stenting increased procedural costs by $1148 and initial hospital costs by $1384 (both P<0.001). By 1-year, stenting led to fewer repeat revascularization procedures and reduced follow-up medical care costs by $1215, such that aggregate costs were similar for the PTCA and stent groups ($18 690 versus $18 859, P=0.75). The cost...
