冠状动脉造影后即刻PCI与择期PCI

目的:比较冠状动脉造影(coronary angiography,CAG)后即刻PCI(percutaneous coronary intervention,PCI)与择期PCI的成功率和并发症率,探讨即刻PCI的临床价值.方法:2005年1～12月在中南大学湘雅二医院行CAG后即刻PCI者入选即刻组(115例),择期PCI者入选择期组(172例).两组患者临床特征、病变血管特征及支架的长度和直径是相似的.病变血管根据1988年ACC/AHA标准分为A型、B型和C型.结果:A型和B型病变的成功率和并发症率两组间比较差异无统计学意义(P＞0.05);C型病变的成功率即刻组低于择期组(P＜0.01),并发症率高于择期组(P＜0.05),两组间比较差异有统计学意义.结论:A型和B型病变CAG后即刻PCI是可以接受的,C型病变不宜CAG后行即刻PCI.CAG后即刻PCI有一定的临床价值.

Immediate or elective PCI after coronary angiography

Objective To compare the success rate and the complication rate of immediate percutaneous coronary intervention (PCI) and elective PCI after coronary angiography(CAG), and to estimate the clinical value of immediate PCI. Methods One-hundred fifteen patients who underwent immediate PCI after CAG were enrolled into the immediate group, and 172 patients on whom PCI and CAG were performed on 2 days were enrolled into the elective group in Second Xiangya Hospital of Central South University during 2005.The clinical manifestations, lesion vessel characteristics, and length and diameter of stents in the 2 groups were similar. Lesion vessels were defined as Type A, B, and C according to the standard of ACC/AHA in 1988. Results The success rate and the complication rate of Type A and B lesion were not significantly different in the 2 groups (P>0.05). The success rate of Type C lesion in the immediate group was lower than that in the elective group (P<0.01). The complication rate of Type C lesion in the immediate group was higher than that in the elective group (P<0.05). Conclusion Type A and B lesions may undergo immediate PCI, while Type C lesion is not suitable to be performed immediately PCI after CAG. Immediate PCI after CAG has some clinical value.
