Abstract 4722: Five-Year Durability of Sirolimus-Eluting Stent in Patients With Unprotected Left Main Coronary Arteries Compared With Bare Metal Stents: Multicenter Registry in Asia
Aim: The aim of this study is to compare the safety and efficacy of Sirolimus-eluting stent (SES) and bare metal stent (BMS) on the outcome of patients with unprotected left main coronary arteries (LMT).
Methods: Complete clinical follow-up to 5 years is being analyzed for 241 patients who received 120 SES and 121 BMS in patients with LMT (male 71.7%, mean age 70.5 yrs) in six high volume Asian centers. Lesion location of LMT was ostial 24 cases (10.0%), mid shaft 38 cases (15.8%) and distal 179 cases (74.3%).
Results: The baseline clinical characteristics between 2 groups were similar. Angiographic and clinical success were achieved in all patients. At 5 years overall cardiac events occurred in 12.5% of SES patients and 38.0% of BMS patients (p<0.001). See figure⇓.
Conclusion: The use of Sirolimus-eluting stent is effective in preventing cardiac events compared with bare metal stent associated with low acute complication and these benefits is durable at least 5 years.
