Abstract: Objective To evaluate the effectiveness of immediate quantitative coronary angiography (QCA) analysis in percutaneous coronary intervention (PCI). Methods The parameters of QCA and conventional methods before and after PCI were compared and statistics was performed by using t test or ANOVA methods. Results One hundred and two patients were enrolled in our study. Significant differences between QCA and conventional methods were found in evaluation of lesion length [ ( 22.9 ± 8.9 ) mm vs (24. 8 ± 10. 6) mm,t = 9. 63, P < 0. 05 ], stenosis diameter [ (3.0 ± 0.4 ) mm vs (2. 9 ± 0. 7) mm, t = 6. 31, P < 0. 05 ] and stenosis area [ ( 87. 8 ± 10. 7 ) mm2 vs ( 85.0 ± 12.9 ) mm2, t = 2. 54, P < 0.05 ], and also in different vessels. Stenosis diameter and stenosis area after stenting in target lesion were lower than the international standards. Conclusion Immediate QCA analysis can be effective in directing stent implantation.
