| 摘 要： | 目的 探讨实时冠状动脉定量分析(QCA)在经皮冠状动脉介入治疗(PCI)中的有效性和可靠件.方法 在PCI治疗中,应用目测法与QCA进行术中分析,采用t检验和方差分析,对两种方法的各项参数进行对比.结果 研究共入选102例患者,应用QCA法与目测法对比,判断病变长度分别为(22.9±8.9)、(24.8±10.6)mm,t=9.63]、狭窄汽径分别为(3.0±0.4)、(2.9±0.7)mm,t=6.31]、狭窄面积分别为(87.8±10.7)、(85.0±12.9)mm2,t=2.54)差异均有统计学意义(P值均<0.05);不同病变之间应用QCA法与目测法对比,判断病变也不同.应用QCA指导支架置入后靶病变直径狭窄率、面积狭窄率均<20%的国际标准.结论 QCA能够有效、可靠地指导支架置入. |

| 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. |
