The use of drug‐eluting stents (DES) vs bare‐metal stents (BMS) in saphenous vein graft (SVG) lesions remains controversial. We conducted a meta‐analysis of all randomized clinical trials comparing the outcomes of DES with BMS in SVG percutaneous coronary interventions. A search of PubMed, Embase, the Cochrane Register of Controlled Trials, and Clinicaltrials.gov was performed for all randomized clinical trials. We evaluated the short‐ and long‐term clinical outcomes of the following: all‐cause mortality, major adverse cardiovascular events (MACE), definite/probable stent thrombosis, target lesion revascularization (TLR), and target‐vessel revascularization (TVR). From a total of 1582 patients in 6 randomized clinical trials, 797 had DES and 785 had BMS. Patients with DES had lower short‐term MACE, TLR, and TVR in comparison with BMS (odds ratio [OR]: 0.56, 95% confidence interval [CI]: 0.35–0.91, P = 0.02; OR: 0.43, 95% CI: 0.19–0.99, P = 0.05; and OR: 0.45, 95% CI: 0.22–0.95, P = 0.04, respectively). However, there were no different outcomes for all‐cause mortality (P = 0.63) or stent thrombosis (P = 0.21). With long‐term follow‐up, there were no significant reductions of MACE (P = 0.20), TLR (P = 0.57), TVR (P = 0.07), all‐cause mortality (P = 0.29), and stent thrombosis (P = 0.76). The use of DES in SVG lesions was associated with lower short‐term MACE, TLR, and TVR in comparison with BMS. However, there were no significant differences with long‐term follow‐up. 相似文献

Objectives : We sought to determine if differences existed in in‐hospital outcomes, long‐term rates of target vessel revascularization (TVR), and/or long‐term mortality trends between patients with diabetes mellitus undergoing percutaneous coronary intervention (PCI) with either a drug‐eluting stent(s) (DES) or a bare metal stent(s) (BMS). Background : Short‐ and long‐term clinical outcomes of patients with diabetes mellitus undergoing PCI with DES versus BMS remain inconsistent between randomized‐controlled trials (RCTs) and observational studies. Methods : Data were collected prospectively on diabetics undergoing PCI with either DES or BMS from January 2000 to June 2008. Demographic information, medical histories, in‐hospital outcomes, and long‐term TVR and mortality trends were obtained for all patients. Results : A total of 1,319 patients were included in the study. Diabetics receiving DES had a significant reduction in index admission MACE compared to diabetics receiving BMS. Using multivariable adjustment, after a mean follow‐up of 2.5 years (maximum 5 years), diabetics who received DES had a 38% decreased risk of TVR compared to diabetics with BMS [HR 0.62 (95% CI: 0.43–0.90)]; diabetics with DES had an insignificant adjusted improvement in long‐term survival compared to diabetics with BMS [HR 0.72 (95% CI: 0.52–1.00)]. These long‐term survival and TVR rates were confirmed using propensity scoring. Conclusions : The use of DES when compared with BMS among diabetics undergoing PCI is associated with significant improvement in long‐term TVR, with an insignificant similar trend in all‐cause mortality. The long‐term results of this observational study are consistent with prior RCTs after adjusting for confounding variables. © 2010 Wiley‐Liss, Inc. 相似文献

Background: Saphenous vein graft (SVG) lesions remain amongst the most challenging lesions for percutaneous coronary intervention (PCI). It is unknown whether drug eluting stents (DES) are superior to bare metal stents (BMS) for such lesions. Our objective is to determine the safety and efficacy of DES compared with BMS for SVG lesions by performing a meta‐analysis of clinical trials and observational studies. Data Sources: PubMed, Cochrane Register of Controlled Trials, conference proceedings, and internet‐based resources of clinical trials. Study Selection: Studies comparing DES vs. BMS for SVG lesions with at least > 30 patients in each study reporting the outcomes of interest [death, myocardial infarction (MI), target vessel revascularization (TVR), stent thrombosis (ST), and the composite of death, TVR and MI (major adverse cardiac events; MACE)] with at least 6 months clinical follow‐up. The primary outcome of interest was death. Results: Two randomized trials, one subgroup analysis of a randomized trial and 26 observational studies comprising a total of 7,994 patients (4,187 patients in DES and 3,807 patients in BMS group) were included in the analysis .Mean follow‐up duration was 21 ± 11 months (6–48 months). In the overall population, MACE events were 19% in DES and 28% in BMS with a risk ratio (RR) of 0.7 (0.6, 0.8) P < 0.00001. This effect of MACE was sustained in studies with >2 years follow‐up with RR of 0.77 (0.65, 0.91) P = 0.003. Death rate was 7.8% in DES and 9% in BMS with a RR of 0.82 (0.7, 0.97) P = 0.02. MI rate was 5.7% in DES and 7.6% in BMS with RR of 0.72 (0.57, 0.91) P = 0.007. TVR was 12% in DES and 17% in BMS with RR of 0.71 (0.59, 0.85) P = 0.0002. ST was 1% in DES and 1.7 % in BMS RR of 0.61 (0.35, 1.06) P = 0.08. Specifically in randomized controlled trials, DES were associated with no significant differences in overall mortality [RR = 1.97; 95% confidence interval (CI), 0.17–23; P = 0.58] or MI (RR = 1.24; 95% CI, 0.3–5.5; P = 0.78) compared with BMS. Conclusions: Based on the results of this meta‐analysis, DES may be considered as a safe and efficacious option for the percutaneous intervention of SVG lesions. © 2010 Wiley‐Liss, Inc. 相似文献

Background : There are limited data on the long‐term safety and efficacy profile of coronary stent implantation in patients with stable coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). Objective : We aimed to assess the 4‐year clinical outcome in patients who received a bare‐metal stent (BMS), sirolimus‐eluting stent (SES), or a paclitaxel‐eluting stent (PES) for the percutaneous treatment of stable angina in our center during 2000–2005. Methods : In the study period, a total of 2,449 consecutive patients (BMS = 1,005; SES = 373; and PES = 1071) underwent a PCI as part of three historical PCI‐cohorts for stable angina and were routinely followed for the occurrence of major adverse cardiac events (MACE). Results : At 4 years follow‐up, 264 BMS patients (26.8%) had a MACE, compared to 75 SES patients (20.9%) and 199 PES patients (23.9%). Multivariate analysis showed that SES and PES were superior to BMS with respect to MACE [hazard ratio (HR) = 0.62, 95% confidence interval (CI): 0.47–0.81; HR = 0.67, 95% CI: 0.55–0.82, respectively]. The occurrence of MACE was significantly lower in the SES and PES population, primarily due to less target‐vessel revascularization (TVR) procedures (HR = 0.53, 95% CI: 0.37–0.75; HR = 0.71, 95% CI: 0.62–0.81, respectively). The occurrence of early, late, and very late stent thrombosis was equally rare with each stent type. There were no significant differences between SES and PES on death, myocardial infarction, TVR, and MACE. Conclusion : These findings suggest that SES and PES result in decreased TVR procedures and MACE compared to BMS at 4 years follow‐up. SES or PES implantation should be the preferred choice over BMS for patients with stable CAD undergoing PCI. © 2010 Wiley‐Liss, Inc. 相似文献

Backgrounds : Relative efficacy and safety of sirolimus‐eluting stents (SES) compared with paclitaxel‐eluting stents (PES) remains controversial. It is unknown whether there are different effect and safety in coronary bifurcation treatment between SES and PES. Objectives : The meta‐analysis was performed to compare the clinical outcomes of SES and PES in coronary bifurcation intervention. Methods : Five head‐to‐head clinical trials of SES versus PES in coronary bifurcation intervention were included. A total of 2,567 patients were involved in the meta‐analysis. Mean follow‐up period ranged from 6 to 35 months. The primary end points were the need for target lesion revascularization (TLR) and main‐branch restenosis. Secondary end points were target vessel revascularization (TVR), cardiac death, major adverse cardiac events (MACE), and stent thrombosis. Results : Compared with PES, SES significantly reduced the risk of TLR (5.3% vs. 10.6%, odds ratio (OR) 0.52; 95% confidence interval (CI) = 0.38–0.70, P < 0.001), main‐branch restenosis (4.59% vs. 12.59%, OR 0.31; 95% CI = 0.18–0.55, P < 0.001) and TVR (7.05% vs. 12.57%, OR 0.58; 95% CI = 0.42–0.81, P = 0.001) in coronary bifurcation intervention. In addition, SES group also had a significantly lower incidence of MACE (8.20% vs. 14.13%, OR 0.58; 95% CI = 0.40–0.84, P = 0.004) than PES group. However, there were no statistical difference with respect to the incidence of cardiac death (1.64% vs. 1.09%, P = 0.19) and stent thrombosis (0.84% vs. 1.08%, P = 0.64) between SES and PES groups. Conclusions : Compared with PES, SES reduced the incidence of TLR, main‐branch restenosis and MACE in coronary bifurcation intervention, while the risk of stent thrombosis was similar between SES and PES groups. © 2011 Wiley Periodicals, Inc. 相似文献

Aims
To compare clinical outcome in Chronic kidney disease (CKD) patients receiving coronary stents according to stent type BMS versus DES and 1st generation versus 2nd generation DES.Methods and Results
PubMed, Cinhal, Cochrane, Embase, and Web of Science were searched for studies including CKD patients. CKD was defined as eGFR < 60 mL/min. We selected n = 35 articles leading to 376 169 patients, of which 76 557 CKD patients receiving BMS n = 35,807, 1st generation DES n = 37,650, or 2nd generation DES n = 3100. Patient receiving DES, compared to BMS, had a 18% lower all‐cause mortality (RR 0.82, 95%CI 0.71‐0.94). The composite of death or myocardial infarction (MI) was lower in DES patients (RR 0.78, 95%CI 0.67‐0.91), as was stent thrombosis (ST) (RR 0.57, 95%CI 0.34‐0.95), target vessel/lesion revascularization (TVR/TLR) (RR 0.69, 95%CI 0.57‐0.84) and death for cardiovascular cause (RR 0.43, 95%CI 0.25‐0.74). We also found a gradient between 1st and 2nd generation DES, through BMS. Second, compared to 1st generation DES, were associated with further relative risk (RR) reduction of ?18% in of all‐cause death, and lower incidence of stent‐related clinical events: ?39% RR of ST risk; ?27 RR of TVR/TLR risk.Conclusions
DES in CKD patients undergoing PCI were superior to BMS in reducing major adverse clinical events. This was possibly explained, by a lower risk of stent‐related events as ST and TVR or TLR. Second, compared to 1st generation DES may furtherly reduce clinical events.7.

Background: Cardiac allograft vasculopathy (CAV) is the leading cause of death after the first year following heart transplantation. We compared restenosis rates, mortality, and other major adverse cardiac events (MACE) between transplant recipients treated with DES and BMS for CAV. Methods: All patients from our heart transplant registry undergoing PCI with stenting for CAV were identified. Procedural data, baseline clinical characteristics, yearly coronary angiography, cardiac events and death were prospectively collected. Primary outcome was in‐stent restenosis (ISR). Secondary outcomes were in‐segment restenosis, target vessel revascularization (TVR), all‐cause mortality and combined MACE. Results: 36 lesions in 25 patients treated with DES were compared with 31 BMS‐treated lesions in 19 patients. There were no significant differences in baseline characteristics. 12‐month incidence of ISR was 0% with DES vs. 12.9% with BMS, P = 0.03. Over mean (±standard error) follow‐up of 51.1 ± 7.5 months this difference was significant for vessels ≤3 mm in diameter, hazard ratio (HR) DES vs. BMS 0.37 (95% CI 0.11 to 0.95) P = 0.037; but not for vessels >3 mm P = 0.45. However, there was no difference in overall longterm patency because of similar rates of in‐segment restenosis between DES and BMS, HR 1.13 (95% CI 0.43 to 2.97) P = 0.81. Also, the rates of TVR, death from any cause and combined MACE were similar; log rank P 0.88, 0.67, and 0.85, respectively. Conclusion: This study suggests that after PCI for cardiac allograft vasculopathy, despite a lower in‐stent restenosis rate in DES compared with BMS, in‐segment restenosis and clinical cardiac endpoints are similar. © 2009 Wiley‐Liss, Inc. 相似文献

Aim: To perform a systematic review and meta‐analysis of studies reporting outcomes after drug‐eluting stent (DES) implantation in chronic total occlusions (CTOs). Methods: A review of publications and online databases in January 2010 retrieved 17 published studies that reported outcomes after DES implantation in CTOs: eight uncontrolled studies, seven nonrandomized comparative studies with bare‐metal stents (BMS), one post‐hoc analysis of a randomized trial, and one randomized trial. Data were pooled using random‐effects meta‐analysis models. Results: All published studies evaluated sirolimus‐ or paclitaxel‐eluting stents. All studies reporting comparative angiographic outcomes revealed less binary angiographic restenosis with DES implantation compared to BMS (odds ratio: 0.15, 95% CI: 0.08, 0.26). Over a mean follow‐up period of 18.9 ± 16.5 months, the cumulative incidence of death, myocardial infarction, or stent thrombosis was similar between DES and BMS in all studies. Target lesion revascularization (odds ratio: 0.13, 95% CI: 0.06, 0.26) and target vessel revascularization (odds ratio 0.18, 95% CI: 0.11, 0.31) at 6–12 months were consistently lower among DES‐treated patients. Similar patterns of safety and efficacy event rates were also observed in studies reporting >12 month outcomes. Conclusions: Compared with BMS, treatment of chronic total coronary occlusions with DES is associated with significant reductions in angiographic and clinical restenosis with similar safety. The consistency and magnitude of treatment effect across both individual trials and the pooled analysis establish DES as the preferred therapy for percutaneous revascularization of CTOs. © 2010 Wiley‐Liss, Inc. 相似文献

Objectives : We compared the long‐term outcomes of drug‐eluting stents (DES) versus bare‐metal stents (BMS) for treatment of bare‐metal in‐stent restenosis (ISR). Background : There are no randomized trials or observational studies directly comparing the safety and efficacy of DES versus BMS for treatment of bare‐metal ISR. Methods : We examined data on all patients who underwent percutaneous coronary intervention (PCI) for ISR at Cleveland Clinic between 05/1999 and 06/2007. We compared the efficacy and safety of DES to BMS for treating bare‐metal ISR. The primary end point was a composite of death, myocardial infarction (MI), or target lesion revascularization (TLR). The secondary endpoints were individual components of the primary endpoint. Results : Of the 931 patients identified over 8 years, 706 had bare‐metal ISR and met our study criteria. Of the 706 patients with bare‐metal ISR, 362 were treated with DES and 344 with BMS. There were 230 cumulative events for a median follow‐up of 3.2 years. After adjusting for 27 variables, DES were associated with lower primary endpoint compared to BMS for treatment of bare‐metal ISR (21% vs. 45%, adjusted hazard ratio [HR] 0.63; 95% confidence interval [CI], 0.42–0.95; P = 0.03). The individual secondary endpoint of death (8% vs. 24%, P = 0.005) favored DES, but MI (3% vs. 8%, P = 0.31), and TLR (13% vs. 20%, P = 0.23) failed to reach statistical significance. Conclusions : In our multivariate analysis of patients with bare‐metal ISR, DES use was associated with significantly lower death, MI, or TLR when compared to BMS. © 2010 Wiley‐Liss, Inc. 相似文献

The efficacy of second‐generation drug‐eluting stents (DES; eg, everolimus and zotarolimus) compared with bare‐metal stents (BMS) in patients undergoing percutaneous coronary intervention was challenged recently by new evidence from large clinical trials. Thus, we aimed to conduct an updated systematic review and meta‐analysis of randomized clinical trials (RCTs) evaluating the efficacy and safety of second‐generation DES compared with BMS . Electronic databases were systematically searched for all RCTs comparing second‐generation DES with BMS and reporting clinical outcomes. The primary efficacy outcome was major adverse cardiac events (MACE); the primary safety outcome was definite stent thrombosis. The DerSimonian and Laird method was used for estimation of summary risk ratios (RR). A total of 9 trials involving 17 682 patients were included in the final analysis. Compared with BMS, second‐generation DES were associated with decreased incidence of MACE (RR: 0.78, 95% confidence interval [CI]: 0.69‐0.88), driven by the decreased incidence of myocardial infarction (MI) (RR: 0.67, 95% CI: 0.48‐0.95), target‐lesion revascularization (RR: 0.47, 95% CI: 0.42‐0.53), definite stent thrombosis (RR: 0.57, 95% CI: 0.41‐0.78), and definite/probable stent thrombosis (RR: 0.54, 95% CI: 0.38‐0.80). The incidence of all‐cause mortality was similar between groups (RR: 0.94, 95% CI: 0.79‐1.10). Meta‐regression showed lower incidences of MI with DES implantation in elderly and diabetic patients (P = 0.026 and P < 0.0001, respectively). Compared with BMS, second‐generation DES appear to be associated with a lower incidence of MACE, mainly driven by lower rates of target‐lesion revascularization, MI, and stent thrombosis. However, all‐cause mortality appears similar between groups. 相似文献

Objective Uncertainty exists regarding the relative performance of drug-eluting stents (DES) versus bare-metal stents (BMS) in octogenarians undergoing percutaneous coronary intervention (PCI). We undertook a meta-analysis to assess outcomes for DES and BMS in octogenarians undergoing PCI. Methods Electronic data bases of PubMed, Cochrane, and EMBASE were searched. We included randomized, controlled clinical trials (RCT) and observational studies comparing DES and BMS in octogenarians receiving PCI. The methodological qualities of eligible trials were assessed using a “risk of bias” tool. The endpoints included all-cause death, major adverse cardiac events (MACE), myocardial infarction (MI), target vessel revascularization (TVR), major bleeding, and stent thrombosis (ST). Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated for each endpoint. Results A total of one RCT and six observational studies were included and analyzed in this meta-analysis. All trials were of acceptable quality. At 30 days, compared with DES-treated patients, BMS-treated patients had a higher incidence of mortality (OR: 3.91, 95% CI: 1.10–13.91; P = 0.03). The OR for MACE (1.52, 95% CI: 0.56–4.17; P = 0.13), MI (0.81, 95% CI: 0.37–2.17; P = 0.23), TVR (0.75, 95% CI: 0.17–3.41; P = 0.41), major bleeding (0.77, 95% CI: 0.35–1.68; P = 0.43), and ST (1.44, 95% CI: 0.32–6.45; P = 0.33) did not reach statistical significance. At one year follow-up, the OR did not favor BMS over MACE (MACE, defined as the composite of death, myocardial infarction, and TVR) (1.87; 95% CI: 1.22–2.87; P < 0.01), MI (1.91, 95% CI: 1.22–2.99; P < 0.01), TVR (3.08, 95% CI: 1.80–5.26; P < 0.01) and ST (3.37, 95% CI: 1.12–10.13; P < 0.01). The OR for mortality (1.51; 95% CI: 0.92–2.47; P = 0.10) and major bleeding (0.85, 95% CI: 0.47–1.55; P = 0.60) did not reach statistical significance. At > 1 year follow-up, the OR for all endpoints, including mortality, MACE, MI, TVR, major bleeding, and ST, did not reach statistical significance. Conclusions Our meta-analysis suggests that DES is associated with favorable outcomes as compared with BMS in octogenarians receiving PCI. 相似文献

Aims: Studies demonstrate that percutaneous coronary intervention (PCI) with drug‐eluting stents (DES) is associated with reduced revascularization and major adverse cardiac events (MACE) rates compared to bare metal stents (BMS) in native coronary vessels. Optimal PCI treatment of saphenous vein graft (SVG) lesions remains unclear despite SVG procedures representing up to 10% of PCI cases. We therefore performed a meta‐analysis to compare outcomes between BMS and DES in SVG PCI. Methods and Results: A search (2004–2009) of MEDLINE and conference proceedings for all relevant studies comparing mortality and MACE outcomes in DES versus BMS in SVG PCI and meta‐analysis of the data was performed. Twenty studies were identified from 2005 to 2009 enrolling a total of 5,296 patients. Meta‐analysis revealed a decrease in mortality associated with DES use, odds ratio (OR) 0.68; 95% confidence interval (CI) 0.53–0.88; P = 0.004. Similarly, MACE (OR 0.64; 95% CI 0.51–0.82; P < 0.001), total lesion revascularization (OR 0.60; 95% CI 0.43–0.83; P = 0.002), and total vessel revascularization (OR 0.57; 95% CI 0.41–0.80; P = 0.001) were significantly decreased in the patients in which DES were used compared to BMS. This reduction in mortality and MACE events associated with DES use appears to be limited to registry studies and not randomized controlled studies. Conclusions: Our meta‐analysis suggests DES use to be safe in SVG PCI and associated with reduced mortality and MACE rates with reductions in revascularization also observed.

Objectives: We aim to explore the clinical outcome of drug‐eluting stents (DES) versus bare‐metal stents (BMS) implantation in diabetics versus nondiabetic patients. Background: Diabetic patients sustain worse long‐term clinical outcomes after percutaneous coronary interventions (PCI) when compared with nondiabetics. The use of DES decreases the rate of repeat revascularization in this population but data concerning long‐term clinical benefits, such as myocardial infarction (MI) or mortality is scant. Methods: We analyzed data from a comprehensive registry of 6,583 consecutive patients undergoing PCI at our center. A propensity score was used for analysis of outcomes and for matching (DES vs. BMS). Outcome parameters were total mortality, MI, repeat target vessel revascularization (TVR) rates, and risk‐adjusted event‐free survival. Within this cohort, we identified 2,571 nondiabetic patients and these were compared with 1,826 diabetic coronary patients. Results: Mean and median follow up time was 3 and 3.25 years, respectively. Overall, diabetics had higher rates of major‐adverse cardiovascular events (MACE) at 4 years compared with nondiabetics (23.03 vs. 31.96 P > 0.001). DES use was associated with lower rates of TVR in both groups [diabetics hazard ratio (HR) = 0.56, 95% confidence interval (CI): 0.42–0.76, P < 0.001, nondiabetics HR = 0.73, 95% CI: 0.55–0.97, P = 0.03] while sustained decreased rates of both mortality and MI were evident solely among diabetics (HR = 0.71, 95% CI: 0.56–0.89, P = 0.004 in diabetic vs. HR = 0.88, 95% CI: 0.69–1.13, P = 0.3). Conclusions: In a “real‐world,” unselected population and extended clinical use, DES in diabetics was associated with sustained decreased rates of MI, death, TVR, and MACE while this benefit was attenuated in the nondiabetic population. © 2011 Wiley‐Liss, Inc. 相似文献

Objective: To investigate long‐term outcomes of unprotected left main coronary artery (ULMCA) disease treatment using drug‐eluting stents (DES). Background: In several studies, DES implantation in ULMCA appeared safe and effective at mid‐term; however, to date, there is limited long‐term data. Methods : All consecutive patients undergoing sirolimus‐ or paclitaxel‐eluting stent implantation in ULMCA disease at a single institution were evaluated. The primary endpoint was long‐term major adverse cardiac events (MACE) defined as cardiac death, nonfatal myocardial infarction, or target lesion revascularization (TLR). Stent thrombosis (ST), according to Academic Research Consortium definitions, was also evaluated. Results: A total of 210 patients were assessed. In‐hospital MACE rate was 1%. During a mean follow‐up of 28.0 ± 14.5 months, MACE occurred in 26 patients (12.5%): cardiac death in nine patients (4.3%) and TLR in 17 patients (8.2%). The cumulative MACE‐free survival rate was 89.0, 87.4, and 85.4% at 1, 2, and 3 years, respectively. ST occurred in three patients (1.4%): one case was definite and the other two were probable/possible ST; there were no cases of very late ST. Binary restenosis occurred in 8.3%. The EuroScore >6 was the only independent predictor of MACE [hazard ratio (HR) 2.24, 95% confidence interval (CI) 1.05–4.77, P = 0.04]. There was a trend toward an increased risk of MACE associated with distal ULMCA location (HR 2.14, 95% CI 0.87–5.29, P = 0.10). Conclusions: Our study showed DES implantation in ULMCA to be feasible, safe, and effective at long term. Randomized trials comparing percutaneous versus surgical revascularization are warranted to define the treatment of choice for ULMCA disease. © 2009 Wiley‐Liss, Inc. 相似文献

Objectives : To ascertain the long‐term safety, efficacy, and pattern of use of drug‐eluting stents (DES) in routine clinical practice. Methods : We analyzed a registry of 6,583 consecutive patients undergoing percutaneous coronary intervention (PCI), of whom 2,633 were treated using DES (DES group) and 3,950 were treated using bare‐metal stents (BMS group). Propensity score was used for stratified analysis of outcomes and for matching. Outcomes were total mortality, myocardial infarction (MI), repeat target vessel revascularization (TVR) rates, and risk‐adjusted event‐free survival. Results : Follow‐up time was 6 months to 5.18 years (mean: 3 years). Patients in the DES group were more likely to be diabetic and had use of longer or more stents, treatment of more lesions and of more proximal main vessels. After propensity score matching, the cumulative mortality was 12.85% in the DES group versus 14.14% in the BMS group (P = 0.001). Use of DES reduced the occurrence of MI (5.17% vs.5.83%, P = 0.046), of clinically driven TVR (9.76% vs. 12.28%, P < 0.001) and of the composite endpoint of death/MI/TVR (23.38% vs. 26.07%; P < 0.001). Conclusions : Our risk‐adjusted event‐free survival analysis indicates a prognostic benefit for DES utilization that sustains up to 5 years following PCI. © 2010 Wiley‐Liss, Inc. 相似文献

Background : There is few information on the long‐term efficacy and safety of sirolimus‐eluting stents (SES) and paclitaxel‐eluting stents (PES) compared to bare metal stents (BMS) in all‐comer percutaneous coronary intervention (PCI)—patients complicated by renal insufficiency (RI). Objective : Our aim was to assess the 6‐year clinical outcome of PCI‐patients with RI treated exclusively with BMS, SES, or PES in our academic hospital. Methods: A total of 1382 patients, included in three cohorts of consecutive PCI‐patients (BMS = 392; SES = 498; PES = 492), were categorized by creatinine clearance calculated by the Cockroft–Gault formula (normal kidney function ≥ 90; mild RI = 60–89; moderate RI < 60) and systematically followed for the occurrence of major adverse cardiac events (MACE). Results : Mortality rates were significantly higher for patients with moderate RI compared to mild RI and normal kidney function at 6 years (Kaplan–Meier estimate: moderate RI (34%) vs. mild RI (12%), P < 0.001; moderate RI (34%) vs. normal kidney function (8%), P < 0.001). After multivariate Cox‐regression analysis, SES and PES decreased the occurrence of target‐vessel revascularization (TVR) and MACE at 6 years in patients with a normal creatinine clearance compared to BMS [adjusted hazard ratio (aHR) = 0.48, 95% CI: 0.28–0.84; aHR = 0.75, 95% CI: 0.57–0.97, respectively] with no significant effect on mortality. Safety‐ and efficacy end points were comparable for the three stent types in patients with mild‐ and moderate renal function. Conclusion : Patients with a normal creatinine clearance had significant improvement in TVR and MACE rates after SES‐ or PES implantation compared to BMS at 6 years. However, there was no superiority of both drug‐eluting stents over BMS in safety and efficacy end points for patients with impaired renal function. © 2012 Wiley Periodicals, Inc. 相似文献

Background: The long‐term safety and effectiveness of drug‐eluting stents (DES) versus bare metal stents (BMS) in non‐ST‐segment elevation myocardial infarction (NSTEMI) beyond 2 years after percutaneous coronary intervention (PCI) is unknown. Methods: We studied 674 NSTEMI patients who underwent successful PCI with DES (n = 323) or BMS (n = 351). The primary study end‐points were time to occurrence of death or nonfatal recurrent myocardial infarction (MI), and stent thrombosis (ST). Secondary end‐points included time to occurrence of target vessel revascularization (TVR) and any major adverse cardiovascular event (MACE, defined as the composite of death, MI, ST, TVR). Results: The DES and BMS groups were well matched except that DES patients received dual antiplatelet therapy for a longer duration and had smaller final vessel diameter. In survival analysis, at a mean follow‐up of 1333 ± 659 days after PCI, the DES group had similar incidence of death/myocardial infarction (24% vs. 27%, log rank p = 0.23) and ST (4.0% vs. 2.6%, p = 0.18) as the BMS group. The DES patients had lower incidence of TVR (8.1% vs. 17%, p = 0.0018) but similar MACE (26% vs. 37%, p = 0.31). In multivariable analysis, DES vs. BMS implantation showed no significant impact on death/myocardial infarction [adjusted hazards ratio (HR) 1.0, 95% confidence intervals (CI) 0.7–1.4], ST (HR 1.7; CI 0.7 – 4.0), or MACE (HR 0.8; CI 0.6 – 1.1). However, TVR was lower in the DES group (HR 0.4; CI 0.3 – 0.7). Conclusion: In patients presenting with NSTEMI, DES implantation appears to be as safe as BMS implantation at long‐term follow‐up. In addition, DES are effective in reducing TVR compared to BMS. (J Interven Cardiol 2012;25:28–36) 相似文献

Background
Polymer‐free drug eluting stents (PF‐DES) were developed, in part, to overcome risk of late ischemic events observed with permanent polymer‐coated DES (PP‐DES). However, trial results are inconsistent with longer‐term safety and efficacy of PF‐DES remaining unknown. We performed a meta‐analysis of randomized trials assessing outcomes of patients receiving PF‐DES versus PP‐DES for treatment of coronary artery disease (CAD).Methods
Electronic searches were performed for randomized trials comparing outcomes between PF‐DES and PP‐DES. Trials reporting major adverse cardiovascular events (MACE), myocardial infarction (MI), stent thrombosis (ST), all‐cause death, target lesion/vessel revascularization (TLR/TVR), and late lumen loss (LLL) were included. Analyses were performed at longest follow‐up and landmarked beyond 1‐year.Results
Twelve trials (6,943 patients) were included. There was no significant difference in MACE between PF‐DES and PP‐DES at longest follow‐up (Odds Ratio [OR] 0.96, 95%CI 0.85‐1.10, P = 0.59) or landmark analysis beyond 1‐year (OR 0.96, 95%CI 0.76‐1.20, P = 0.70). Although PF‐DES were associated with a significant reduction in all‐cause death (OR 0.85, 95%CI 0.72‐1.00, P < 0.05), this effect was not present on landmark analysis beyond 1‐year (OR 0.89, 95%CI 0.73‐1.10, P = 0.30). There were no differences observed for MI (OR 1.00, 95%CI 0.77‐1.28, P = 0.99) or ST (OR 0.95, 95%CI 0.54‐1.68, P = 0.86), with similar efficacy outcomes including TVR (OR 1.07, 95%CI 0.91‐1.26, P = 0.42), TLR (OR 1.03, 95%CI 0.88‐1.21, P = 0.68) and angiographic LLL (pooled mean difference 0.01 mm, 95%CI ?0.08 to 0.11, P = 0.76).Conclusions
PF‐DES are as safe and efficacious as PP‐DES for the treatment of patients with CAD, but do not significantly reduce late ischemic complications.19.

AIMS: Controversy exists about the clinical significance of in-stent late loss (ISLL) after drug-eluting stent (DES) implantation. We sought to clarify whether ISLL after DES implantation is related to a potential clinical impact. METHODS AND RESULTS: We included in a meta-regression analysis 21 trials (8641 patients) that randomly compared DES with bare-metal stents (BMS). We evaluated the relationship between angiographic behaviour of DES and the clinical impact of using DES instead of BMS in each trial using meta-regression techniques, weighting by the number of patients included in each trial. Mean ISLL in patients allocated to DES and DeltaISLL (difference in ISLL in patients allocated to BMS and DES) were used as angiographic parameters of efficacy of DES. The number of patients needed to be treated (NNT) to prevent one target lesion revascularization (TLR) was used to quantify the clinical impact of using DES instead of BMS. There was a significant relationship between mean ISLL in patients allocated to DES and the clinical benefit of using DES instead of BMS, as measured with the NNT for TLR: NNT for TLR = 6.2 + 18.4 [ISLL-DES] (R = 0.62; P = 0.007). Therefore, a 0.1 mm increase in mean ISLL-DES was associated with a 1.8 increase in NNT for TLR. There was also a significant association between the degree of inhibition of neointimal hyperplasia of DES in comparison with BMS with the NNT for TLR: NNT for TLR = 17.1-11.8 [DeltaISLL] (R = 0.61; P = 0.008). Therefore, a 0.1 mm reduction in ISLL by using DES instead of BMS was associated with a 1.2 decrease in mean NNT for TLR. CONCLUSION: There is a strong and significant association between the degree of inhibition of neointimal formation with the use of DES and the clinical impact of using DES instead of BMS. 相似文献

OBJECTIVES: This study sought to determine the clinical and angiographic outcomes after drug-eluting stent (DES)-supported percutaneous coronary intervention (PCI) for chronic total coronary occlusion (CTO). BACKGROUND: There are few data about the efficacy of DES-supported PCI for CTO. METHODS: All consecutive patients who had a sirolimus-eluting stent or a paclitaxel-eluting stent implanted for CTO from December 2003 to December 2004 were analyzed. Clinical and angiographic outcomes of patients treated with DES were compared with a case-matched control group of patients treated with bare metal stents (BMS) in the 12 months before the routine use of DES. RESULTS: Successful DES-supported PCI was performed in 92 patients and 104 CTO. The case-matched control group consisted of 26 patients and 27 CTO successfully treated with BMS. There were no differences between groups in baseline clinical and angiographic characteristics. Stent length in the DES group was higher as compared with that of BMS group (51+/-28 mm vs. 40+/-19 mm, P=0.073). The 6-month major adverse cardiac event (MACE) rate was lower in the DES group as compared with that of BMS group (9.8% vs. 23%, P=0.072). The angiographic follow-rate was 80% in the DES group and 81% in the BMS group. The 6-month restenosis rate was 19% in the DES group and 45% in the BMS group (P<0.001). By multivariate analysis, it was found that in the DES group, the only predictors of restenosis were stented segment length (OR 1.031, 95% CI 1.01-1.06, P=0.009) and a target vessel reference diameter<2.5 mm (OR 6.48, 95% CI 1.51-27.83, P=0.012), while the only predictor of MACE was stent length (OR 1.04, 95% CI 1.01-1.08, P=0.006). CONCLUSIONS: DES implantation for CTO decreases the risk of mid-term restenosis and MACE. Small vessels and diffuse disease requiring the implantation of multiple stents and very long stents for full coverage of the target lesion are still associated with a relatively high risk of restenosis. 相似文献
