Abstract:
Objective To compare the safety and efficacy of sirolimus-eluting stents (SES) and Pixel stents (PS) for treatment of coronary small vessel disease. Methods From March 2003 to January 2005, 67 patients with coronary small vessel disease were randomly divided into two groups: group A (n=34) and group B (n=33). Group A was treated with SES and group B with PS. The procedural success rate, major adverse cardiac events, restenosis rate and late lumen loss were compared between two groups. Results Procedural success rate in both groups was 100% without remained stenosis and cardiac complications. There were 30 patients in group A and 29 in group B whose quantitative coronary angiography was obtained 9 months after the procedure. Two patients in group A had recurrent angina because of in-stent restenosis, and 6 out of 7 patients with the angina in group B had angiographic evidence of in-stent restenosis. No death occurred in both groups during clinical follow-up. Angiographic restenosis rate was 6.7% in group A and 20.7% in group B (P
