BACKGROUND: Recently, several randomized and controlled trials have demonstrated great advantages of a drug-eluting stent (DES) with respect to significant reduction in restenosis and recurrence of symptoms, and improvement in clinical outcomes after percutaneous coronary intervention (PCI). Little is known about the comparative effects of the 1-DES plus the kissing balloon technique with the 2-DES for bifurcation angioplasty in a Chinese population. METHODS: From April 2004 to June 2006, 566 consecutive Chinese patients underwent DES implantation for true bifurcation lesions, including 346 1-DES with the kissing balloon technique (300 male, 57.7 +/- 11.5 y old) and 220 2-DES (183 male, 58.1 +/- 10.7 y old) were analyzed. Clinical and angiographic follow-up was performed after 7 mo. RESULTS: The major adverse cardiac event (MACE) rates were higher in the 2-DES group than in the 1-DES group (5.5% versus 2.0%; p = 0.032), which was mainly contributed to by acute myocardial infarction (AMI) (4.5% versus 1.4%; p = 0.032), rather than death and target lesion revascularization (TLR) (0% versus 0.5%; p = 0.389, 1.4% versus 2.7%; p = 0.352). Stent thrombosis rates were higher in the 2-DES group than in the 1-DES group (0.6% versus 2.7%; p = 0.042), except for 1 late-stent thrombosis in the 2-DES group, and all of them were subacute stent thrombosis (2 in the 1-DES group and 5 in the 2-DES group). The 7 mo angiographic follow-up rate was 36.4%. In the main branch there was no difference in restenosis rate in the 1-DES group compared with the 2-DES group (9.8% versus 11.9%; p = 0.652), but in the side branch the restenosis rate was higher in the 1-DES group (33.6% versus 15.5%; p = 0.004). However, there was no difference in in-segment late loss between the 2 groups, either in the main or side branch. CONCLUSION: Compared with the 2-DES strategy, if a final kissing balloon could be achieved, the 1-DES strategy may be more efficient and safe.
