目的评价后扩张对冠心病弥漫性长病变患者冠状动脉支架术(PCI)后支架再狭窄的影响.方法将2008年1月至2014年1月住院治疗的92例冠心病弥漫性长病变患者随机分为后扩张组47例和对照组45例,后扩张组在常规冠状动脉支架术完成后给予支架内后扩张,对照组不采用后扩张.比较两组患者术后12个月支架再狭窄及主要不良心血管事件发生情况.结果 PCI术后12个月后扩张组支架内再狭窄的发生显著低于对照组(2.1％与17.7％),差异有统计学意义(P=0.03).后扩张组的主要不良心血管事件发生率较对照组降低(6.4％与24.4％),差异有统计学意义(P=0.03).结论后扩张可能降低冠心病弥漫性长病变患者支架术后支架再狭窄的发生及主要不良心血管事件发生.

Objective To evaluate the effect of post-dilatation on in-stent restenosis of long lesion coronary heart disease patients received percutaneous coronary artery interventional(PCI) therapy.Methods A total of 92 cases coronary heart disease patients in Gaoxin Hospital of Xi'an from January 2008 to January 2014 were randomly divided into the post-dilatation deployment group (n =47) and control group (n =45).The postdilatation deployment group were given stent after expansion after conventional coronary stenting, while the control didn't use after expansion.The clinical features and profile of drug-eluting stent(DES) implantation and stent restenosis(examined by 256-shce spiral computed tomography coronary angiography(MSCTCA) and major adverse cardiac events(MACE) within hospitalization and 12 months were observed.Results Stent restenosis occurred in 1 patient(2.1％) in the post-dilatatioh deployment group and 8 patients(17.7％) in the control group in 12 months examed by MSCTCA,the difference was significant(P=0.03).MACE occurred in 3 patients (6.4％) in the post-dilatation deployment group and 11 patients (24.4％) in the control group, the difference was significant (P =0.03).Conclusion Routine post-dilatation tactics is effective for long lesion coronary heart disease patients with PCI.It is associated with lower coronary restenosis and lower MACE.
