Abstract

BACKGROUND: Previously we reported the inhibition of coronary restenosis with Abciximab (ReoPro(R))-coated stent in a porcine model. ReoPro(R) inhibits platelet aggregation, the proliferation of vascular smooth muscle cells and inflammatory reaction.
METHODS
We performed a prospective randomized trial to compare two types of stents for the revascularization in native coronary artery. The primary effective end points were major adverse coronary events (MACE): cardiac death, acute myocardial infarction, target vessel revascularization (TVR), restenosis at 6-month clinical and angiographic follow-up.
RESULTS
One hundred fifty-five patients were enrolled between Aug, 2001 and Jun, 2003. Mean ages (56.0 +/- 10.0 vs. 56.9 +/- 10.8 years), baseline diameter stenosis and minimal luminal diameter were not different between the two groups. There was one myocardial infarction and revascularization during hospital stay in control stent group. During clinical follow-up, there were two myocardial infarctions in control group. Follow-up coronary angiogram was done 62.3% (48/77) in coated and 65.4% (51/78) in control groups. Diameter stenosis and late loss were significantly less in the ReoPro(R)-coated stent group compared with controls (16.4 +/- 5.8% vs. 34.3 +/- 6.1%, p=0.009; and 0.33 +/- 0.28 mm vs. 0.88 +/- 0.41 mm; p=0.002). The restenosis and TVR rates of ReoPro-coated stent were relatively lower compared with control stent [14.6% (7/48) vs. 29.4% (15/51), p=0.062; and 9.2% (7/76) vs. 14.7% (11/75); p=0.327].
CONCLUSION
A ReoPro(R)-coated stent is safe and may be effective in the prevention of coronary restenosis.
