and to determine the predictors of MACEs after either sirolimus-eluting stent (SES) or paclitaxel-eluting stent (PES) implantation in diabetic patients during 3-year follow-up. Methods: Diabetic patients with de novo coronary lesions (169 patients with 190 lesions) were randomly assigned prospectively to either SES or PES in 6 different cardiovascular centers. Results: Baseline clinical and angiographic characteristics were similar EHWZHHQWKHJURXSV7KHUDWHVRI0$&(V >Q @LQWKH6(6YV >Q @LQWKH3(6*URXSS  DQGGH¿QLWHVWHQWWKURPERVLV >Q @LQ WKH6(6YV>Q @LQWKH3(6*URXSS  ZHUHVLPLODUEHWZHHQWKH 2 groups during the 3-year follow-up.

Conclusion: The use of either SESs or PESs was effective in reducing MACEs (death, nonfatal MI, TLR), TVR, and stent thrombosis during the 3-year follow-up. Moreover, insulin treatment was a main predictor of TLR, TVR, and MACEs during the 3-year follow-up after either SES or PES implantation.

Comparison of Zotarolimus-Eluting Stents versus Sirolimus- and Paclitaxel-Eluting Stents for the Treatment of Multivessel Coronary Artery disease Hyung Oh Choi, Duk-Woo Park, Won-Jang Kim, Seung-Whan Lee, Young-Hak Kim, Cheol Whan Lee, Jae-Joong Kim, Seong-Wook Park, Seung-Jung Park Asan Medical Center, Seoul, Republic of Korea Objectives: Data comparing second-generation zotarolimus-eluting stents =(6  ZLWK ¿UVWJHQHUDWLRQ VLUROLPXV 6(6  DQG SDFOLWD[HOHOXWLQJ VWHQWV (PES) for treatment of multivessel coronary disease (MVD) have been limited. Methods: We performed the subgroup analysis of patients with MVD from the ZEST trial comparing ZES with SES and PES in daily clinical practice. A total of 1254 patients with MVD were treated with ZES (414 patients), SES (430 patients), and PES (410 patients). The primary end point was the composite clinical outcomes of death, myocardial infarction, and ischemia driven target vessel revascularization (TVR) at 12month after index procedure. Results: Most of baseline demographics and angiographic characteristics were similar among the 3 groups. At 12 months, the rate of primary end point in the ZES group (12.2) was similar to the SES group (10.2), but superior to the PES group (17.6) (Figure 1).

TCT-433 Ostial Stenting for the Isolated Ostial Lesion of Left Anterior Descending Artery: Effectiveness of Sirolimus-eluting Stent Yasushi Fuku, Kazushige Kadota, Suguru Otsuru, Masao Imai, Daiji Hasegawa, Seiji Habara, Hiroyuki Tanaka, Shingo Hosogi, Tsuyoshi Goto, Kazuaki Mitsudo Kurashiki Central Hospital, Kurashiki City, Japan Background: For the treatment of the isolated ostial lesion of left anterior descending artery (LAD), ostial stenting using bare metal stent (BMS) has been reported to be not effective. However, there is a possibility that ostial stenting using drug-eluting stent (DES) can be another strategy in the DES era. Therefore, we compared the midterm clinical and angiographic results between sirolimus-eluting stent (SES) and BMS. Methods: In this retrospective study, 90 consecutive patients with the isolated ostial lesion of LAD underwent SES (n=45) or BMS (n=45) implantation EHWZHHQ -DQXDU\  DQG -XO\  ,VRODWHG RVWLDO OHVLRQ RI /$' ZDV GH¿QHGDV•VWHQRVLVZLWKLQPPRIRVWLXPRI/$'ZLWKRXWWKHGLVWDO OHVLRQRI/07RUWKHRVWLDOOHVLRQRIOHIWFLUFXPÀH[DUWHU\ /&;  Results: The patient and procedural characteristics at baseline were similar except the higher prevalance of patients with acute coronary syndrome in the BMS group.

Conclusions: For patients with multivessel coronary disease, the use of ZES resulted in similar major adverse cardiac events to SES, but in fewer events than PES.

Conclusion: Although the rate of TVR in patients who received SES is independent of BMI, underweight patients were more associated with adverse clinical events than normal, overweight and obese patients. TCT-435

Conclusions: The angiographic outcome of ostial stenting with SES as opposed to BMS was excellent for the isolated ostial lesion of LAD. Ostial stenting using SES could be another effective strategy for the treatment of the isolated ostial lesion of LAD.
