Abstract:
Objective To compare intravascular ultrasound (IVUS) and coronary angiography in measuring the lumen diameter and coronary arteries stenosis rate, to investigate the impact of IVUS in the choice of surgical indications, surgical procedure guidance and effects of operation.Methods The patients who underwent percutaneous coronary intervention(PCI) therapy from may 2013 to may 2014 were divided into IVUS-guided intervention therapy group (n=89) and coronary angiographyguided group (n=90).Their baseline parameters, lesion features, MACE and restenosis during follow-up were analyzed.Results Baseline clinical and angiographic characterisitcs were well matched and show no significant differences between the two groups.Compared to angiography-guided group, the minimum lumen diameter (MLD) of IVUS-guided group were higher, diameter stenosis (DS) and lesion length (LL) were lower in IVUS-guided intervention therapy group.The detection rate of calcified and eccentric lesion were significantly higher in IVUS-guided group.There were 204 (93.6 ％) and 195 (87.8％) high-pressure balloons used in post-inflation in two groups, respectively.The MLD and plaque burden of IVUS-guided group were obviously improved after stent implantation.Conclusions IVUS-guided intervention therapy in PCI is safe and effective, may be helpful for the judgment of lesion, evaluating stent implantation and guiding high-pressure balloon post-inflation.IVUS-guided intervention could get the bigger immediate lumen diameter and lower plaque burden than coronary angiography without serious short-term or long-term complications.
