RESUMO

Objective To investigate the relationship between serum cystatin C (Cys C) level and the occurrence of in-stent restenosis after coronary drug-eluting stent implantation.Methods A retrospective analysis of coronary drug-eluting stent implantation was curried out in 592 patients.All patients were from Shengjing Hospital of China Medical University by coronary angiography,and were divided into restenosis group (142 cases) and non restenosis group (450 cases).The Cys C levels before and after surgery and follow-up angiography were analyzed.The biochemical indicators,and transcatheter arterial restenosis were analyzed.Results Either before or after operation and follow-up angiography,serum cystatin C levels were higher in restenosis group patients than that in non restenosis group [before operation:(1.622 ± 1.063) mg/L vs (1.369 ± 0.860) mg/L;after the operation:(1.769 ± 1.062) mg/L vs (1.458 ± 0.883) mg/L;review:(1.924 ± 1.085) mg/L vs (1.440 ± 0.874) mg/L;P < 0.05].Multivariate COX regression analysis showed that serum cystatin C level was an independent risk factor of in-stent restenosis in drugeluting area (P < 0.05).Conclusions The serum cystatin C level is closely related to in-stent restenosis in drug-eluting stents area.High level of serum cystatin C is an independent risk factor of in-stent restenosis after drug-eluting stents implantation.

RESUMO

Objective: Our purpose was to evaluate a new kind of tomographic phase analysis in Wolff-Parkinson-White (WPW) syndrome . Methods:Planar and new tomographic gated blood pool scintigraphy were performed in 66 patients with WPW syndrome and 55 healthy subjects , in which 30 patients were examined again after radiofrequency ablation . The abnormal initial contractions in both planar and tomographic phase image were compared with the sites of accessory pathway (ACP) based on ECG and radiofrequency ablation .Results:The phase angle shift in WPW group was significantly different from that in healthy subjects .New tomographic phase analysis can detect the sites of ACP more precisely than planar phase analysis and ECG ( 93.9%, 80.3%, 79.0%, respectively ).The average phase angle shift in WPW group after operation was less than that before operation (P< 0.01 ) .Tomographic phase analysis discovered two mutiple ACPs and latent ACP that can not be found by ECG. Conclusion:The new tomographic phase analysis is a promising method to detect the sites of ACP and can be used to evaluate the efficacy of operation.
