Abstract:
The risk factors of coronary artery disease, angiographic and procedural features are the main risk factors of restenosis after coronary artery stent implantation. In different combinations, these risk factors have different effects on coronary restenosis. The risk factors that the results of trials were more consistent include coronary lesion length, lesion vessel diameter <3 mm, ostial disease, total stent length, and number of stent. The same results of trials as stated above indicated that drug-eluting stent (sirolimus-eluting stent and paclitaxel-eluting stent), compared with bare-metal stent, significantly decreased the risk of restenosis. Compared these two drug-eluting stent, sirolimus-eluting stent was superior to paclitaxel-eluting stent on lowering the risk of restenosis. About other risk factors, e.g. age, sex, smoking, hypertension, the results of trials had inconsistent.
