Abstract：Objective To research the changes of blood vessels of coronary artery disease stent,and further discuss the influences of stenting vascular remodeling.Methods Twenty eight stents Percutaneous coronary inter vention(PCI) was implanted because of all sorts of acute coronary events.Using intravascular ultrasound method,measure the stent placement stents proximal ( 1 cm) vascular volume.One year later,recheck with coronary angiography and repetitive measure the blood vessels volume,SPSS software analysis package was used to do X? inspection statistical comparison.Results 28 patients ( positive remodeling 23 cases,zero remodeling 1 case,and negative remodeling 4 cases).The largest remodeling can reach to 89％ an average of (23.0 ±5.7) ％.Negative remodeling average is ( 12.0 ± 1.1 ) ％ ; There are 3 ischemic events of heart,13 cases stent narrow in positive remodeling,The most bassoon and cavity area narrow gets to 70％ ; And in 1 case of zero remodeling and 4 cases of negative remodeling there is no ischemia incident subgroup.Results Show different risk factors of differeut types of remodeling,and the comparison analysis has a statistical significance.Conclusion It might have relevances between stents proximal blood vessels and positive to remodel restenosis stents and remind us to make a choice discreetly of the necessary of stents.
