Abstract
BACKGROUND: Stenting improves cardiac outcome in comparison with balloon angioplasty. Compared with conventional surgery, off-pump bypass surgery on the beating heart without cardiopulmonary bypass may reduce morbidity, hospital stay, and costs. The purpose, therefore, was to compare cardiac outcome, quality of life, and cost-effectiveness 1 year after stenting and after off-pump surgery.
METHODS AND RESULTS: Patients referred for angioplasty (n=280) were randomly assigned to stenting (n=138) or off-pump bypass surgery. At 1 year, survival free from stroke, myocardial infarction, and repeat revascularization was 85.5% after stenting and 91.5% after off-pump surgery (relative risk, 0.93; 95% CI, 0.86 to 1.02). Freedom from angina was 78.3% after stenting and 87.0% after off-pump surgery (P=0.06). Quality-adjusted lifetime was 0.82 year after stenting and 0.79 year after off-pump surgery (P=0.09). Hospital stay after the initial procedure was 1.43 and 5.77 days, respectively (P<0.01). Stenting reduced overall costs by 2933 dollars (26.2%) per patient (8276 dollars versus 11 209 dollars; P<0.01). Stenting was more cost-effective in 95% of the bootstrap estimates.
CONCLUSIONS: At 1 year, stenting was more cost-effective than off-pump surgery while maintaining comparable cardiac outcome and quality of life. Stenting rather than off-pump surgery, therefore, can be recommended as a first-choice revascularization strategy in selected patients.
