RESUMO
OBJECTIVE: Percutaneous coronary intervention (PCI) has been widely used to treat obstructive coronary artery disease. With the advent of drug-eluting stent (DES) in real world registry was proved as promising therapy. The limitation of the use of DES is the limited health care expenditure. We propose the use of Chinese made DES among Thai patients and that this will solve the cost issue. The clinical result of this DES has not been well known. METHODS: Prospective study from November 2005 to March 2007 using the structured registry form to evaluate the safety and efficacy of new Chinese made Firebird sirolimus eluting stent (Firebird SES) on clinical parameters from in-hospital, 30 days and 12 months or longer term follow-up. End point is major adverse cardiac event (MACE) including death, MI, TLR and CABG at 30 day and cumulative MACE at 12 month follow-up. RESULTS: Ninety consecutive patients who were treated with Firebird stent implantation (107 target lesions) were analyzed. Angiographic success (defined as < 30% diameter stenosis) was 85%. Procedure success was 77.8%. MACE at 30 day was 16.6%, cumulative MACE at 12 months was 18.8%. There were total 9 deaths during the study period, two deaths occurred at before 30 days, 3 deaths occurred before 12 months and other 4 deaths occurred after 12 months to 1305 days. Eighty patients (88.9%) had either office visit or telephone call follow-up after 12 months, 38 patients (42.2%) underwent clinical driven coronary arteriography, binary restenosis was 26.3%. Shock and smoking history was the analyzed predictor of MACE at follow-up. CONCLUSION: The implantation of Firebird DES in unselected patients (all comers) is safe, effective and could be an alternative choice of stent for Thai patients.
