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 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

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

Background: Multiple randomized trials and observational studies have shown drug‐eluting stents (DES) to be safe and effective at 3‐year follow‐up in stent thrombosis (ST)‐segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). However, outcomes data beyond 3–4 years after DES implantation are sparse. Methods: We studied 554 STEMI patients who underwent successful PCI with either DES or bare metal stent (BMS). Primary study end‐points were time to occurrence of ST and the composite of death or myocardial infarction (MI). Secondary end‐points were time to occurrence of major adverse cardiac events (MACEs) and discrete events that comprise MACE (death, MI, and target vessel revascularization [TVR]). Outcomes of the DES and BMS groups were assessed by survival analysis and multivariable Cox regression. Results: There were 205 (37%) patients who received DES and 349 (63%) patients who received BMS. At a median follow‐up of 41.4 months after PCI, there were no differences in the unadjusted incidence of ST (ST, 3.4 vs. 4.3%, log‐rank P = 0.61) and MI (6.8% vs. 8%, P = 0.61) between DES versus BMS groups, respectively. However, DES implantation was associated with lower unadjusted incidence of death or MI (11% vs. 23.5%, P = 0.0002), MACE (16% vs. 34%, P < 0.0001), death (6.3% vs. 17%, P = 0.0004), and TVR (9.8% vs. 18%, P = 0.008) than BMS implantation. In multivariable analyses, DES implantation was associated with significantly lower incidence of MACE (adjusted HR = 0.47 [95% CI: 0.31–0.76], P = 0.0007) than BMS implantation. Conclusion: In our study of STEMI patients, DES implantation was safer than BMS implantation and was associated with lower MACE at long‐term follow‐up. (J Interven Cardiol 2012;25:118–125) 相似文献

Background: Small randomized trials have shown short‐term improved outcome with drug‐eluting stents (DES) over bare metal stent (BMS) in saphenous vein graft (SVG) interventions by reducing in‐stent restenosis and target vessel revascularization (TVR). It is not clear, however, if these benefits are maintained long term. The aim of this study is to compare the outcome in a larger cohort of patients undergoing SVG stent implantation with DES or BMS, at 2 years. Methods: From among 250 patients who underwent SVG stenting, 225 patients with available follow‐up were selected from data bases at the three participating institutions. One‐hundred‐six patients had DES (sirolimus, paclitaxel or tacrolimus eluting stent) and 119 patients had any available BMS from April 2002 to December 2006. The primary endpoint was MACE rate, a combination of cardiac death, S‐T elevation myocardial infarction (STEMI) and target lesion revascularization. Secondary end points were the individual components of the primary endpoint. Follow‐up was obtained by mailed interviews or telephone calls and review of the hospital chart. Results: The DES and BMS groups had similar age (71 ± 8 years vs. 70 ± 7 years, P = 1.0), diabetes (45% vs. 36%, P = 0.3), history of MI (58% vs. 51%, P = 0.6), EF (44% vs. 47%, P = 0.2) and previous PCI (40% vs. 35%, P = 0.4). Reference vessel diameter (3.15 ± 0.5 mm vs. 3.5 ± 0.5 mm. P = 0.001) and stent size (3.3 ± 0.4 mm vs. 3.9 ± 0.5 mm, P = 0.001) were smaller in the DES group; however, the BMS were longer (24 ± 10 mm vs. 21 ± 6 mm, P = 0.05). At one year there was a trend (P = 0.1) for lower MACE rate in the DES group, but at two years there was no difference in MACE free survival between the DES and BMS groups (81 % vs. 82%, P = 0.9). The death rate was similar (6% each) with three patients having STEMI (two in the DES and one in the BMS). TVR was also similar (14% in each group). Conclusion: In patients undergoing treatment of SVG disease with a stent, the marginal benefit of DES seen at 1 year was lost at 2‐year follow‐up. © 2008 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

Objectives : The Oral Rapamycin in ARgentina (ORAR) III trial is a randomized study comparing a strategy of oral rapamycin (OR) plus bare‐metal stent (BMS) versus a strategy of drug‐eluting stents (DES) in patients with de novo coronary lesions. The purpose of this study was to assess the 3 years cost‐effectiveness outcome of each strategy. Background : OR after BMS has been associated with reduction of target vessel revascularization (TVR) although its value in long‐term efficacy in comparison with DES is unknown. Methods : In three hospitals in Buenos Aires, Argentina, 200 patients were randomized to OR plus BMS (n = 100) or DES (n = 100). Primary objectives were costs and effectiveness. Cost analysis included in‐hospital and follow‐up costs. Safety was defined as the composite of death, myocardial infarction (MI), and stroke. Efficacy was defined as TVR. Results : Baseline characteristics between groups were similar. The 3‐year follow‐up rate was 99%. Cardiac mortality was 2% and 5% in OR group and DES group, respectively (P = 0.44). The composite of death, MI and stroke rate was 11% in OR group and 20% in DES group (P = 0.078). TVR rate was 14.5% in OR group and 17.6% in DES group (P = 0.50), respectively. Three year cumulative costs were significantly lower in the OR arm as compared to the DES arm (P = 0.0001) and DES strategy did not result cost‐effective according to the non‐inferiority test. Conclusions : At 3 years follow‐up, there were no differences in effectiveness between the two strategies, and DES strategy was not more cost‐effective as compared to OR plus BMS. © 2011 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

Objectives : The aim was to investigate the 7‐year clinical outcomes of patients treated with either drug‐eluting stents (DES) or bare‐metal stents (BMS) for saphenous vein graft disease (SVG). Background : Atherosclerotic disease in SVG has several peculiarities which make it difficult to extrapolate outcomes of the use of DES as compared to BMS, from outcomes observed in native coronary arteries. To date no long‐term safety and efficacy results for DES in SVG have been published. Methods : Between January, 2000 and December, 2005 a total of 250 consecutive patients with saphenous vein graft disease were sequentially treated with DES (either sirolimus‐ or paclitaxel‐eluting stents) or with BMS. Yearly follow‐up was performed. Results : At 87 months (7.25 years), a total of 101 patients died (58 [46%] in the BMS group and 43 [42%] in the DES group, P‐value= 0.4). There was no significant difference in the combined endpoint mortality or myocardial infarction. Cumulative target vessel revascularisation (TVR) was higher in the BMS group compared to the DES group (41% vs. 29%, respectively; adjusted hazard ratio [HR] 0.63, 95% confidence interval [CI]: 0.39–1.0). The cumulative incidence of major adverse cardiac events was 73% vs. 68% in the BMS and DES groups, respectively (adjusted HR 0.93, 95% CI: 0.67–1.3). Conclusions : In the present study, the unrestricted use of DES for SVG lesions appeared safe and effective up to 7.25 years‐ and the use of DES resulted in a clinically relevant lower rate of TVR. © 2011 Wiley Periodicals, Inc. 相似文献

Background : Drug eluting stents (DES) have recently been proven to further reduce restenosis and revascularization rate in comparison to bare metal stents in elective procedures. Most early DES trials did not include patients undergoing primary percutaneous coronary intervention (PCI) for ST‐segment elevation MI, because these patients tend to have lower restenosis rates than other patient groups and delayed endothelization of these stents raises concern about a possible increase of thrombotic complications in the setting of STEMI. Aim : To confirm the safety and effectiveness of DES in patients with STEMI in a real‐world scenario. Methods : From January 2004 to December 2006, clinical and angiographic data of 370 patients with STEMI treated with primary PCI have been analyzed. Patients were retrospectively followed for the occurrence of major adverse cardiac events (MACE): death, reinfarction and target vessel revascularization (TVR). Results : Overall, 120 patients received DES (32%, DES group) and 250 received bare metal stents (68%, BMS group) in the infarct related artery. Compared with the BMS group, DES patients were younger, (mean age 56 ± 12 vs. 65 ± 10; P < 0.001) had more often diabetes mellitus (47% vs. 14% P < 0.001), anterior localization (65% vs. 45%; P < 0.0011) and less cardiogenic shock at admission (4% vs. 7%; P < 0.001). The angiographic characteristics in the DES group showed longer lesions (23 mm vs. 19 mm) and smaller diameter of vessels (2.5 mm vs. 3.0 mm). After a median follow‐up of 24 ± 9 months, there was no significant difference in the rate of stent thrombosis (1.6% in the DES group vs. 1.2% in the BMS group, P = ns). The incidence of MACE was significantly lower in the DES group compared with the BMS group (HR 0.56 [95% CI: 0.3–0.8]; P = 0.01), principally due to the lower rate of TVR (HR 0.41 [95% CI: 0.2–0.85]; P = 0.01). Conclusions : Utilization of DES in the setting of primary PCI for STEMI, in our “real world,” was safe and improved the 3‐year clinical outcome compared with BMS reducing the need of TVR. © 2008 Wiley‐Liss, Inc. 相似文献

Objective : We aimed to compare the long‐term clinical outcomes of first‐vessel percutaneous coronary intervention (PCI) with drug‐eluting stents (DES) and bare metal stents (BMS) for the treatment of transplant coronary artery disease (TCAD). Background : TCAD is the leading cause of late death in orthotopic heart transplantation (OHT) recipients. PCI is associated with worse clinical outcomes compared with non‐OHT patients. Our institution previously reported superior angiographic outcomes with DES compared with BMS in OHT patients. However, long‐term clinical outcomes comparing PCI with DES versus BMS are lacking. Methods : The data on 105 OHT recipients who underwent first‐vessel PCI with DES (n = 58) or BMS (n = 47) at UCLA Medical Center between 1995 and 2009 were retrospectively analyzed. Results : Five‐year clinical outcomes were not significantly different with DES and BMS in terms of the composite of death, myocardial infarction (MI), or target vessel revascularization (TVR) [(40.8 ± 7.2)% vs. (59.6 ± 7.2)%, log‐rank P = 0.33], death [(31.8 ± 7.8)% vs. (40.4 ± 7.2)%, log‐rank P = 0.46], MI [(12.2 ± 6.2)% vs. (11.3 ± 5.4)%, log rank P = 0.98], TVR [(25.5 ± 6.9)% vs. (26.5 ± 7.3)%, log rank P = 0.76], and time to repeat OHT [(2.27 ± 1.79) vs. (3.22 ± 3.34), P = 0.98]. Conclusions : At long‐term follow‐up, PCI with DES and BMS provided similar clinical outcomes in OHT. Long‐term mortality remains high in OHT recipients after PCI with either DES or BMS. Randomized clinical trials are required to determine the optimal treatment strategy for OHT recipients with TCAD. © 2012 Wiley Periodicals, Inc. 相似文献

OBJECTIVES: The purpose of the present report was to evaluate clinical and angiographic outcomes of drug-eluting stent (DES) implantation in saphenous vein graft (SVG) lesions. BACKGROUND: The safety and efficacy of DES implantation for the treatment SVG lesions remains uncertain. METHODS: We evaluated in-hospital and six-month outcomes in 61 consecutive patients treated with DES in SVG lesions from March 2002 to March 2004 (DES group), as compared to 89 consecutive patients treated with bare-metal stents (BMS) in the 24 months immediately before the introduction of DES (BMS group). Major adverse cardiac events (MACE) including death, myocardial infarction, target lesion revascularization (TLR), and target vessel revascularization (TVR) were recorded in-hospital and at six-month follow-up. RESULTS: The rate of in-hospital MACE was similar between the two groups (6.6% vs. 5.6%, p = 1.0). Cumulative MACE at six months was 11.5% in the DES group and 28.1% in the BMS group (p = 0.02). The DES group had a significantly lower incidence of in-segment restenosis (10.0% vs. 26.7%, p = 0.03), TLR (3.3% vs. 19.8%, p = 0.003), and TVR (4.9% vs. 23.1%, p = 0.003). By Cox regression analysis, diabetes (hazard ratio [HR]: 3.03; 95% confidence interval [CI]: 1.33 to 6.90; p = 0.008), usage of BMS (HR: 2.53; 95% CI: 1.07 to 5.97; p = 0.03), and age of SVG (HR: 1.10; 95% CI: 1.02 to 1.19; p = 0.02) were identified as predictors of MACE at six-month follow-up. CONCLUSIONS: Compared to BMS implantation, DES implantation in SVG lesions appears safe with favorable and improved mid-term outcomes. 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.

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.15.

Objectives: We assessed outcomes of patients undergoing drug-eluting stent (DES) vs. bare metal stent (BMS) implantation for complex lesions excluded from pivotal clinical trials of DES.
Background: Although DES improve target vessel revascularization (TVR) and major adverse cardiovascular events (MACE) compared to BMS in randomized trials, data on safety and efficacy of DES in complex lesions are insufficient.
Methods: In a single-center registry of 1,354 patients who underwent stent implantation for complex lesions between July 2001 and December 2005, we compared the incidence of death, death or myocardial infarction (MI), stent thrombosis [definite or probable by the Academic Research Consortium (ARC) criteria], TVR, and MACE between patients who received DES (n = 483) versus those who received BMS (n = 871). Mean duration of follow-up was 494 versus 838 days in DES and BMS groups, respectively.
Results: Clinical outcomes in DES versus BMS groups were as follows: death 5.2% versus 11.5% (log-rank P = 0.042); death/MI 11.2% versus 16.7% (P = 0.47), stent thrombosis 2.9% versus 2.6% (P = 0.61), TVR 6.6 versus 18.5% (P < 0.0001), MACE 14.9% versus 29.7% (P = 0.0002), respectively. After adjustment for baseline differences, DES implantation was associated with lower TVR (adjusted hazards ratio HR = 0.38, 95% CI 0.26–0.56, P < 0.0001) and MACE (HR = 0.56, CI 0.42–0.74, P < 0.0001) without significant impact on other outcomes. In 933 patients who underwent DES (n = 483) or BMS (n = 450) implantation in the year 2003 or later, DES implantation similarly lowered TVR and MACE without affecting other outcomes.
Conclusions: Our findings support the safety and efficacy of DES in patient subsets excluded from pivotal randomized clinical trials of DES. 相似文献

BackgroundDrug eluting stents (DES) are preferred over bare metal stents (BMS) for native coronary artery revascularization unless contraindicated. However, the preferred stent choice for saphenous venous graft (SVG) percutaneous coronary interventions (PCI) is unclear due to conflicting results.MethodsPubMed, Clinical trials registry and the Cochrane Center Register of Controlled Trials were searched through June 2018. Seven studies (n = 1639) comparing DES versus BMS in SVG-PCI were included. Endpoints were major adverse cardiac events (MACE), cardiovascular mortality, all-cause mortality, myocardial infarction (MI), target vessel revascularization (TVR), target lesion revascularization (TLR), in-stent thrombosis, binary in-stent restenosis, and late lumen loss (LLL).ResultsOverall, during a mean follow up of 32.1 months, there was no significant difference in the risk of MACE, cardiovascular mortality, all-cause mortality, MI, stent thrombosis, TVR and TLR between DES and BMS. However, short-term follow up (mean 11 months) showed lower rate of MACE (OR 0.66 [0.51, 0.85]; p = 0.002), TVR (OR 0.47 [0.23, 0.97]; p = 0.04) and binary in-stent restenosis (OR 0.14 [0.06, 0.37]; p < 0.0001) in DES as compared with BMS. This benefit was lost on long-term follow up with a mean follow up 35.5 months.ConclusionIn this meta-analysis of SVG-PCI, DES use was associated with similar MACE, cardiovascular mortality, all-cause mortality, MI, in-stent thrombosis, TVR and TLR compared with BMS during long-term follow up. There was high incidence of MACE noted in both DES and BMS suggesting a need for exploring novel strategies to treat SVG disease to improve clinical outcomes. 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

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

OBJECTIVES: To address the safety and efficacy of drug-eluting stents (DES) in the treatment of intermediate lesions, we performed a pooled analysis of four randomized DES versus bare-metal stent (BMS) trials and assessed outcomes among patients with intermediate lesions. BACKGROUND: Before the introduction of DES, intermediate coronary lesions were commonly managed based on physiologic or anatomic assessment of lesion severity. The DES may challenge this paradigm. METHODS: The study population involved 167 of 2,478 randomized patients (6.7%) with intermediate lesions (diameter stenosis <50% [mean 44%] by quantitative coronary angiography) from the Sirolimus-coated Bx Velocity Balloon Expandable Stent in the Treatment of Patients with De Novo Coronary Artery Lesions (SIRIUS), TAXUS-IV, and the First and Second First Use to Underscore Restenosis Reduction with Everolimus (FUTURE-I and -II) trials. End points examined included early (in-hospital and 30-day) and late (1-year) major adverse cardiac events (MACE), including cardiac death, myocardial infarction (MI), target vessel revascularization (TVR), stent thrombosis, and follow-up angiographic restenosis. RESULTS: Patients with intermediate lesions randomized to DES versus BMS had low rates of 30-day MACE (1.1% vs. 4.0% respectively; p = 0.22). At one-year follow-up, patients treated with DES versus BMS had similar rates of cardiac death (0% vs. 2.7%, respectively; p = 0.11) and MI (3.4% vs. 5.4%; p = 0.49) but markedly lower rates of TVR (3.4% vs. 20.3%; p = 0.0004), MACE (5.6% vs. 25.4%; p = 0.0003), and binary angiographic restenosis (1.8% vs. 34.0%; p < 0.0001). No patient in either group developed stent thrombosis. CONCLUSIONS: Compared with BMS, treatment of intermediate lesions with DES appears safe and results in a marked reduction in clinical and angiographic restenosis. The efficacy of DES may require a reevaluation of current treatment paradigms for intermediate lesions. 相似文献

Objective : Our aim was to compare the long‐term outcomes between drug‐eluting stents and bare‐metal stents for saphenous vein graft stenosis. Background : The ideal type of stent to treat saphenous vein graft stenosis has not been clearly established. Short‐term randomized controlled trial results comparing drug‐eluting stents with bare‐metal stents for saphenous vein graft stenosis are conflicting, intermediate‐term retrospective studies and meta‐analyses at two years suggest no difference in outcomes, and there are no long term follow‐up studies. The need for long term follow‐up data has become emerged with concern over late stent thrombosis. Methods : 246 saphenous vein graft patients undergoing stenting from August 2002–December 2008 were studied. Overall survival and event‐free survival were compared by Kaplan‐Meier method. Hazard ratios (HR) were calculated by Cox‐proportional hazards models. Results : We treated 133 patients with DES (median follow‐up four years) and 113 patients with BMS (median follow‐up four years) for SVG stenosis. Overall survival (77.0% ± 3.9% vs. 70.6% ± 4.6%, log‐rank P = 0.60) and MACE‐free survival (57.5% ± 4.6% vs. 56.8% ± 4.9, log‐rank P = 0.70) were not significantly different between the DES and BMS groups. Although BMS was associated with increased risk of target lesion revascularization (TLR) (freedom from TLR 85.2% ± 3.5% vs. 90.0% ± 3.0%, HR 2.07, 95% CI 0.97–4.42, log‐rank P = 0.05), there was no significant difference in the freedom from myocardial infarction (86.7% ± 3.3% vs. 88.7% ± 3.2%, log‐rank P = 0.39) or target vessel revascularization (77.1% ± 4.2% vs. 76.1% ± 4.2%, log‐rank P = 0.33) between the two groups. Conclusions : Although mortality is not statistically different between DES and BMS for SVG stenosis, BMS is associated with increased risk of revascularization, thus suggesting the superiority of DES over BMS in the long term. © 2011 Wiley Periodicals, Inc. 相似文献
