The cumulative MACE rate for 5 years were not different between twogroup ( 20.4% in BMS vs. 18% in DES, p¼0.592). The rate of MI (3.1% in BMS vs.2.4% in DES, p¼0.513), death (3.7% in BMS vs. 2.0% in DES, p¼0.361) and TVR(12% in BMS vs. 10.6% in DES, p¼0.694) were not different. There was no dif-ference in MACE-free survival rate between the DES group and the BMS group(93.1% in DES vs 90.7% in BMS, P¼0.472).Conclusions: Clinical outcomes between DES and BMS are similar in a large vesseldiameter and single coronary arterial lesion for 5 years.TCT-639Impact Of The Length Of Bare Metal Stent On Clinical Events AfterPercutaneous Coronary Intervention In Current Clinical PracticeIgnacio Sanchez-Perez
