Background New-generation drug-eluting stents (DES) was more effective in the treatment of in-stent restenosis (ISR) compared with the first-generation DES. drug-eluting balloons (DEB) and new-generation DES had been available strategies in treatment of bare-metal stents/DES ISR (BMS/DES-ISR). Six new randomized trials have recently examined the angiographic outcomes and one-year clinical outcomes of DEB and new generation DES in BMS/DES-ISR. However, the optimal management for BMS/DES-ISR lesions remains controversial. Methods We searched the randomized clinical trials evaluating the angiographic outcomes and one-year clinical outcomes of DEB and new-generation DES in patients with BMS/DES-ISR. The primary endpoints were the angiographic outcomes, including the minimal luminal diameter (MLD), diameter stenosis %(DS%), late lumen loss (LLL), and binary restenosis (BR). Results A total of six randomized clinical trials with 1177 BMS/DES-ISR patients were included in our meta-analysis. For angiographic outcomes, there were significantly less MLD and more DS% with DEB compared to new-generation DES (MLD: MD =?0.18, 95% CI:?0.31– ?0.04, P < 0.001;DS%: MD = 5.68, 95% CI: 1.00–10.37, P < 0.001). Moreover, for one-year clinical outcomes, DEB was associated with a significant increase risk in target lesion revascularization (TLR)(RR = 2.93, 95% CI: 1.50–5.72, P = 0.002). However, DEB was associated with higher risks of major adverse cardiac event, target vessel revascularization, TLR, BR, and more DS% only in DES-ISR group. Conclusions DEB and new-generation DES have the similar clinical efficacy for the treatment of BMS-ISR. However, DES showed more MLD, less DS%, and a decreased risk of TLR for the treatment of DES-ISR.

Background There are limited data comparing long-term clinical outcomes between first-generation (1G) and second-generation (2G) drug-eluting stents (DESs) in patients who underwent successful percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO) lesion. Methods A total of 840 consecutive patients who underwent PCI with DESs for CTO lesion from January 2004 to November 2015 were enrolled. Finally, a total of 324 eligible CTO patients received 1G-DES (Paclitaxel-eluting stent or Sirolimus-eluting stent, n = 157) or 2G-DES (Zotarolimus-eluting stent or Everolimus-eluting stent, n = 167) were enrolled. The clinical endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), total repeat revascularization [target lesion revascularization (TLR), target vessel revascularization (TVR), and non-TVR]. We investigated the 5-year major clinical outcomes between 1G-DES and 2G-DES in patient who underwent successful CTO PCI. Results After propensity score matched (PSM) analysis, two well-balanced groups (111 pairs, n = 222, C-statistic = 0.718) were generated. Up to the 5-year follow-up period, the cumulative incidence of all-cause death, re-MI, TLR, TVR and non-TVR were not significantly different between the two groups. Finally, MACE was also similar between the two groups (HR = 1.557, 95% CI: 0.820–2.959, P = 0.176) after PSM. Conclusions In this study, 2G-DES was not associated with reduced long-term MACE compared with 1G-DES following successful CTO revascularization up to five years.

Efficacy of Short-term Dual Antiplatelet Therapy after Implantation of Second-generation drug-eluting Stents:A Meta-analysis and Systematic Review

引用

Chinese Medical Sciences Journal 2017年第1期32卷 1-12页

作者： Peisen Huang Yuan Yu Xikun Han Yuejin Yang State Key Laboratory of Cardiovascular Disease Fuwai HospitalNational Center for Cardiovascular Diseases Chinese Academy of Medical Sciences & Peking Union Medical College Beijing 100037 China National Clinical Research Center of Cardiovascular Diseases Fuwai HospitalNational Center for Cardiovascular Diseases Chinese Academy of Medical Sciences & Peking Union Medical College Beijing 100037 China

Objective The benefit of short-term dual antiplatelet therapy(DAPT) following second-generation drug-eluting stents implantation has not been systematically evaluated. To bridge the knowledge gap,we did a meta-analysis to assess the efficacy of ≤6 months versus ≥12 months DAPT among patients with second-generation drug-eluting stents. Methods We searched online databases and identified randomized controlled trials that assess the clinical impact of short-term DAPT(≤6 months) published before March 3,2016. The efficacy endpoints included the incidence of all-cause death,myocardial infarction,cerebrovascular accidents,and definite or probable stent thrombosis. Safety endpoint defined as major bleeding was also evaluated and discussed. Results We included 5 trials that randomized 9473 participants(49.8%,short-term DAPT duration vs. 50.2%,standard duration). A total of 9445(99.7%) patients reported the efficacy endpoints,and the safety endpoint was available from 4 studies(n=8457). There was no significant difference in efficacy endpoints between short-term and standard DAPT duration(≥12 months) [risk ratio(RR) 0.96; 95% confidence intervals(CI),0.80-1.15]. Short-term DAPT duration did not significantly increase the individual risk of all-cause death,myocardial infarction,cerebrovascular accidents,or definite or probable stent thrombosis. Although short-term DAPT obviously reduced risk of major bleeding compared with standard DAPT(RR 0.53; 95% CI,0.29-0.96),significant publication bias was found when accessing the safety endpoint of the 4 studies(Egger's test,P=0.009). Conclusions The efficacy of short-term DAPT was comparable with that of standard duration *** less than 6 months may be appropriate for patients receiving second-generation drug-eluting stents implantation.

AIM To assess the usefulness of intra-arterial contrastenhanced ultrasonography(IAUS) during transarterial chemoembolization(TACE) with drug-eluting beads(DEB) for hepatocellular carcinoma(HCC).METHODS Thirty two patients with 39 HCC underwent DEB-TACE guided with IAUS, and examined by contrast-enhanced ultrasonography(CEUS) or dynamic CT after DEB-TACE were enrolled in this study. CEUS findings before DEBTACE and IAUS findings were compared. Treatments judged to be complete and incomplete for lesions were appropriate and insufficient, respectively. Findings on CEUS and/or dynamic CT performed 1, 3 and 6 mo after DEB-TACE were evaluated using m RECIST(CR/PR/SD/PD).RESULTS The treatments were complete and incomplete in 26 and 13 lesions, respectively. On imaging evaluation using CEUS and/or dynamic CT one month after treatment, 25 and 1 lesions were judged to be CR and PR, respectively, and at 6 mo after treatment, the results were CR, PR, SD and PD for 24, 1, 0 and 1 of these lesions, respectively, in the 26 completely treated lesions. Of the 13 lesions in which treatment was incomplete, the results on imaging at one month after treatment were CR, PR, SD and PD for 0, 6, 4 and 3 lesions, respectively. The overall CR rate at 6 mo after treatment was 61.5%(24/39).CONCLUSION A combination of DEB-TACE with IAUS can improve the therapeutic effects in patients with HCC.

treatment of left main coronary artery （LMCA） disease in select patients. However, it is unclear whether drug-eluting stents （DESs） have better outcomes in patients with LMCA disease compared with bare-metal stent （BMS） during long-term follow-up in Chinese populations. Methods： From a perspective multicenter registry, 1136 consecutive patients, who underwent BMS or DES implantation for unprotected LMCA stenosis, were divided into two groups： 1007 underwent DES implantation, and 129 underwent BMS implantation. The primary outcome was the rate of major adverse cardiac events （MACEs）, including cardiovascular （CV） death, myocardial infarction （MI）, and target lesion revascularization （TLR） at 5 years postimplantation. Results： Patients in the DES group were older and more likely to have hyperlipidemia and bifurcation lesions. They had smaller vessels and longer lesions than patients in the BMS group. In the adjusted cohort of patients, the DES group had significantly lower 5 years rates of MACE （19.4% vs. 31.8%, P = 0.022）, CV death （7.0% vs. 14.7%, P = 0.045）, and MI （5.4% vs. 12.4%, P = 0.049） than the BMS group. There were no significant differences in the rate of TLR （10.9% vs. 17.8%, P = 0.110） and stent thrombosis （4.7% vs. 3.9%, P = 0.758）. The rates of MACE （80.6% vs. 68.2%, P = 0.023）, CV death （93.0% vs. 85.3%, P - 0.045）, TLR （84.5% vs. 72.1%, P = 0.014）, and MI （89.9% vs. 80.6%, P = 0.029） free survival were significantly higher in the DES group than in the BMS group. When the propensity score was included as a covariate in the Cox model, the adjusted hazard ratios for the risk of CV death and M1 were 0.41 （95% confidence interval [C/l： 0.21-0.63, P = 0.029） and 0.29 （95% CI： 0.08-0.92, P = 0.037）, respectively. Conelusions： DES implantation was associated with more favorable clinical outcomes than BMS implantation for the treatment of LMCA disease even though there was no significant difference in the rate of TLR between the two groups.

drug-eluting Stent for the Treatment of Early Fistula Failure

引用

International Journal of Clinical Medicine 2011年第3期2卷 196-200页

作者： Luigi Di Serafino Laura Scudiero Mario De Laurentis Federica Ilardi Fabio Magliulo Giuseppe Carotenuto Cinzia Perrino Giovanni Esposito 不详

Introduction: Morbidity and mortality in chronic haemodialysis patients is related to dialysis efficiency. Several complications may occur with vascular access, usually associated with a stenosis. This is known to occur frequently in the venous outflow. Stenosis of the arterial side is not as frequently discussed, but it is also likely to compromise fistula function. Traditionally, surgical and percutaneous interventions have been used to treat failing fistulas, but the employment of drug-eluting stents for the treatment of failing fistulas due to the arterial stenosis has been described rarely. Methods: A 65-year-old male patient referred to our ambulatory because of hand ischemia during haemodialysis treatments only few days after radial-cephalic fistula creation. After physical and echo-color-doppler examination, angiography was performed and percutaneous intervention was proposed. After the positioning of a guiding catheter, the lesion was crossed with a 0.014” guide wire followed by direct drug-eluting stent implantation. Results: Final angiogram showed a good result and a preserved flow through the fistula. Six months later the patient was asymptomatic and the fistula was still working. Conclusion: Although further prospective studies are necessary, percutaneous transluminal angioplasty (PTA) with drug-eluting stents implantation could be considered a safe and effective technique for the treatment of arteriovenous fistulas stenosis.

Optimizing the Duration of Dual Antiplatelet Therapy After Implantation of drug-eluting Coronary Stents

引用

Chinese Medical Journal 2015年第6期128卷 711-713页

作者： Ying Shen Wei-Feng Shen Department of Cardiology Ruijin Hospital Shanghai Jiaotong University School of Medicine Shanghai 200025 China

Percutaneous coronary intervention （PCI） with implantation of drug-eluting stents （DESs） has become the standard of care for coronary artery disease and gives a great impetus to device industry. In 2013, approximately half million patients with coronary artery disease underwent PCI in China with a penetration rate of DES reaching beyond 95%.131 The use of DES including domestic ones is highly effective in preventing coronary restenosis, but there is a collateral cost to be borne in terms of delayed healing or re-endothelialization of the stented arterial segment and risk of stent thrombosisJ41 Therefore.
