BACKGROUND
The Firebird 2(TM) sirolimus-eluting stent (Firebird 2 stent) is a second-generation sirolimus-eluting stent which has a cobalt-chromium alloy stent platform, a brand new bracket structure, and two layers of styrene-butylenes-styrene polymer coatings with better biocompatibility. The Firebird 2(TM) cObalt-Chromium alloy sirolimus-elUting Stent registry (FOCUS registry) aimed to evaluate the safety and efficacy of the Firebird 2 stent in patients with coronary artery disease in daily practice.
METHODS
The FOCUS registry is a prospective, non-randomized, international multi-center, single-arm clinical registry. Between March 2009 and February 2010, 5084 patients receiving at least 1 Firebird 2 stent during daily clinical practice at 83 medical centers were enrolled.
RESULTS
Of the 5084 patients enrolled in the registry, 5077 and 5058 were respectively available for 30 days and 6 months follow-up. The 30-day rate of major adverse cardiac events (MACE) was 1.20%, including 13 cardiac deaths, 46 non-fatal myocardial infarction (MI), and 6 target vessel revascularization (TVR). At 6 months follow-up, the rate of MACE was 1.80%. There were 32 cardiac deaths, 48 non-fatal MI, and 15 TVR. According to the Academic Research Consortium definition, definite/probable stent thrombosis (ST) occurred in 0.43% (22/5058) of patients, including 8 cases of acute ST, 11 subacute ST, and 3 late ST.
CONCLUSIONS
The Firebird 2 stent showed the promising efficacy and safety at 30 days and 6 months in a real-world population of patients with coronary artery diseases.
