Abstract:

BACKGROUND: Rapamycin eluting stent and its derivative-the everolimus eluting stent can improve the general inflammatory reaction after stent implantation in patients with acute coronary syndrome, and reduce the incidence of restenosis. Firebird stent as a domestic rapamycin eluting stent is currently the most widely used in China, while XIENCE.V stent as an everolimus eluting stent is the most widely used

OBJECTIVE: To compare the effects of domestic Firebird stent and imported XIENCE.V stent on serum high-sensitivity C-reactive protein and interleukin-6 levels after stent implantation in elderly patients with non-ST segment elevation acute coronary syndrome.
METHODS: Totally 112 elderly patients with non-st segment elevation acute coronary syndrome, including 65 cases of acute non-ST segment elevation myocardial infarction and 47 cases of unstable angina pectoris, were enrolled from September 2012 to July 2014. After 72 hours medical treatment, the patients were subject to percutaneous coronary intervention and divided into two groups: Firebird stent group and XIENCE.V stent group. RESULTS AND CONCLUSION: There was no difference in the levels of serum high-sensitivity C-reactive protein and interleukin-6 between the two groups after stent implantation. The serum high-sensitivity C-reactive protein and interleukin-6 levels at 24 hours after stenting were significantly increased in each group compared with the baseline (P < 0.01), while the levels of high-sensitivity C-reactive protein and interleukin-6 were declined significantly after
1 month of stent implantation (P < 0.05). However, there was no difference in the levels of serum high-sensitivity C-reactive protein and interleukin-6 between the two groups at 24 hours, 1 week, and 1 month after stent implantation. No cardiac accidents occurred in the two groups during and 1 month after percutaneous coronary intervention and stent implantation. Two groups had similar security and histocompatibility. The results confirm that both of Firebird stent and XIENCE.V stent can inhibit inflammatory responses and have similar clinical efficacy in elderly patients with non-ST segment elevation acute coronary syndrome.
