Abstract:
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.
