Abstract/OtherAbstract:
We compared the effectiveness of drug-eluting stents (DESs) to bare-metal stents (BMSs) in ostial lesions from an unrestricted patient cohort with 3-year follow-up. DESs have proved more effective at decreasing repeat revascularization rates compared to BMSs in patients with uncomplicated coronary artery disease. Whether DESs provide similar benefits in ostial lesions is not clearly defined. We analyzed data from 775 patients in the National, Heart, Lung, and Blood Institute Dynamic Registry undergoing stenting of ostial lesions with DESs or BMSs. Patients were followed for 3 years for the occurrence of myocardial infarction (MI), repeat revascularization (coronary bypass surgery/repeat percutaneous coronary intervention), and death. In total 439 patients had 464 ostial lesions treated with BMSs and 336 patients had 351 ostial lesions treated with DESs. Adjusted DES versus BMS 3-year hazard ratios were 1.03 (95% confidence interval 0.60 to 1.78, p = 0.90) for death, 1.40 (0.83 to 2.37, p = 0.21) for MI, and 0.81 (0.59 to 1.11, p = 0.19) for repeat revascularization. In patients undergoing percutaneous coronary intervention for aorto-ostial disease (n = 200), death and repeat revascularization did not differ between stent types, but DES-treated patients had more MI during follow-up. For coronary ostial disease (n = 574), 3-year observed rates of death or MI did not differ; however, repeat revascularization was more common in the BMS group. In conclusion, use of DESs for ostial lesions was associated with no difference in the hazard of death, MI, or overall rates of repeat revascularization compared to BMS use.
