Abstract:We performed this study in order to compare the immediate and mid-term outcomes of sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES) in lesions of the unprotected left main coronary artery (LMCA). We assessed 54 patients from 5 centers who had undergone unprotected LMCA stenting (35 SES and 19 PES). The procedural success rates were 100 and 95%, respectively, in the SES and PES patients (p = 0.19). At the 6-month clinical follow-up, the event-free probability was 100% in the SES group, and 88% in the PES group (p = 0.07). At the 6-month angiographic follow-up (n = 24), the SES group exhibited a slightly lower late loss than did the PES group (0.24 +/- 0.44 vs. 0.65 +/- 0.60 mm, p = 0.09), and the restenosis rates were 8 and 9% (p = 0.94) in the SES and PES patients, respectively. In conclusion, both groups exhibited excellent in-hospital and 6-month outcomes with no significant differences between them.
