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/Objective : In this era of drug eluting stents (DES), the long‐term outcome of percutaneous intervention (PCI) on saphenous venous grafts (SVG) is unknown. The objective of the study was to compare the long‐term outcomes of DES versus bare metal stent (BMS) in this population and to determine the predictors of outcomes. Methods : We reviewed the medical records of all patients who had PCI performed during January 2003 to February 2005 to obtain data cardiac risk factors, medications at discharge, angiographic details and outcomes. Results : One hundred and nine patient had PCI to SVG; of these, 37 patients received DES and the remaining had BMS. Over a mean follow‐up of 33 months, the PCI using DES was associated with 30% restenosis, 35% target vessel revascularization (TVR) and major adverse cardiac event (MACE) rate of 46% versus 35% restenosis, 38% TVR and 50% MACE rate with BMS. There was no significant difference in long‐term outcome with DES as compared to BMS. Conclusion : There was no difference in the long‐term outcomes of PCI on SVG irrespective of the type of stent used. © 2008 Wiley‐Liss, Inc. 相似文献

Background: Few data are available on diabetic patients undergoing percutaneous coronary intervention (PCI) in the context of unprotected left main coronary artery (ULMCA) disease. The main goal of this study was to present the long‐term relative benefits of using drug‐eluting stent (DES) instead of bare‐metal stent (BMS) for diabetic patients submitted to percutaneous ULMCA treatment in a large real world multicenter registry. Methods: The GISE‐SICI registry is a retrospective, observational multicenter registry promoted by the Italian Society of Invasive Cardiology in which 19 high‐volume participating centers enrolled 1,453 consecutive patients who underwent PCI on ULMCA between January 2002 and December 2006. From the registry, a total of 398 consecutive patients with diabetes mellitus who underwent DES (n = 321) or BMS (n = 77) implantation were analyzed, with extensive multivariable adjustments. Results: At 3‐years, use of DES in diabetic patients resulted in no significant differences with respect to death (HR 0.56, 95% CIs 0.24–1.28), myocardial infarction (HR 0.82, 95% CIs 0.21–3.26), and the composite end‐point of death or myocardial infarction (HR 0.56, 95% CIs 0.27–1.20). Conversely, DES were associated with significant reduction of target lesion revascularization (TLR, HR 0.33; 95% CIs 0.14–0.80, P = 0.001) rates. Conclusions: Patients presenting with ULMCA disease in the context of diabetes mellitus who are treated with stent‐supported PCI have a significant reduction in the rate of TLR with no increased risk of death or myocardial infarction. © 2009 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

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

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

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 : 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

OBJECTIVES: The aim of this study was to compare the procedural characteristics and outcomes of patients with acute myocardial infarction treated with drug-eluting stents (DES) vs. bare metal stents (BMS). BACKGROUND: DES have been shown to reduce the incidence of restenosis and target vessel revascularization (TVR) in clinical randomized studies when compared with BMS in patients undergoing elective percutaneous intervention. Limited data are available with the use of DES in patients with acute ST-segment elevation myocardial infarction. METHODS: Two hundred and sixty-one consecutive patients who presented with myocardial infarction between 7/2001 and 8/2005 were studied. The procedural characteristics, 30-day and 12-month outcomes of 131 patients treated with DES were compared with 130 patients treated with BMS. RESULTS: At 12-months follow-up DES therapy was associated with a substantial decrease in major adverse cardiovascular events (MACE) (HR 0.33; P =0.002), TVR (HR 0.19; P =0.002), and recurrent myocardial infarction (HR 0.23; P =0.051) vs. BMS therapy. Coronary interventions utilizing DES were characterized by a marked increase in the number of stent per target vessel (DES: 1.9 +/- 0.9 vs. BMS: 1.38 +/- 0.6, P < 0.0001), treatment of bifurcation (DES: 21% vs. BMS: 5%, P =0.0004), and multivessel intervention (DES: 22% vs. BMS: 8%, P =0.003). CONCLUSION: The routine use of DES in acute myocardial infarction is associated with reduced rates of MACE at 12 months vs BMS, despite a higher rate of complex procedures in the DES treated patients. In addition to its anti-restenosis effect, the improved outcome of patients treated with DES may be linked to a more complete revascularization in association with prolonged clopidogrel therapy. 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

Objective : To compare late outcomes with the routine use of drug‐eluting stents (DES) compared with bare‐metal stents (BMS) during percutaneous intervention (PCI) of saphenous vein grafts (SVGs). Background : Safety concerns >1 year from stent implantation have been raised about DES used for PCI of SVGs in a small randomized clinical trial. However, there are few studies comparing late outcomes of DES and BMS in routine clinical practice. Methods : Clinical outcomes (nonfatal MI, cardiac mortality) were assessed in 74 consecutive patients who received BMS and 74 consecutive propensity score matched patients that received DES for PCI of SVGs. Clinical follow‐up was censored at 2 years ± 30 days for both stent groups. Results : At 2 years, the hazard ratio for DES compared with BMS for PCI of SVGs for target vessel revascularization was 0.54 (0.21–1.36), nonfatal MI or cardiac death was 0.68 (0.27–1.68), cardiac mortality 1.19 (0.32–4.45), and stent thrombosis 0.49 (0.09–2.66). Similar outcomes were observed stratified by propensity score quintile. Conclusions : The routine clinical use of DES for PCI of SVGs was associated with a safety profile that was similar to that of bare metal stents with a clear trend toward a less frequent need for reinterventions. © 2008 Wiley‐Liss, Inc. 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

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 : 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 : To describe clinical outcome after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) due to graft failure. Background : Limited data are available on outcome after PCI for graft failure‐induced ACS in the drug‐eluting stent (DES) era. Methods : Patients were identified who underwent PCI either with DES or BMS for ACS due to graft failure between January 2003 and December 2008. Follow‐up was performed at 1 year and April 2011. The primary endpoint was the composite of death, myocardial infarction (MI), or target vessel revascularization (TVR). Kaplan–Meier estimates were calculated at 1 and 5‐year follow‐up. Predictors were identified by backward selection in Cox proportional hazards models. Results : A total of 92 patients underwent PCI, of which 77 were treated with bare metal stents (BMS) and 15 with DES. Patient and procedural characteristics were similar in both groups. Mean follow‐up was 3.2 years. Five‐year composite event rate was 65.9% after BMS vs. 43.4% after DES implantation (P = 0.17). Individual endpoints were comparable in both groups. Recurrence of angina, hospitalization, and repeat interventions were similar. After multivariable adjustment, the use of DES was not associated with a significant reduction in the primary endpoint (HR = 0.44, 0.18–1.04, p = 0.06). Conclusion : In patients presenting with ACS due to acute graft failure, long‐term outcomes remain poor. In a nonrandomized comparison with BMS, DES use was not associated with significant improved long‐term clinical outcomes. © 2012 Wiley Periodicals, 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

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.18.

BACKGROUND: Recent randomized trials have demonstrated conflicting results regarding the use of drug-eluting stents (DESs) as compared to bare metal stents (BMSs) in primary percutaneous coronary intervention (PCI). We compared outcomes among patients presenting with acute ST-elevation myocardial infarction (STEMI) who received DES with those who received BMS. METHODS: In-hospital, 30-day, 6-month, and 1-year outcomes of a cohort of 122 patients who underwent primary or facilitated PCI and received a BMS were compared to 122 propensity-matched patients who received a DES. Seventy-two patients received sirolimus-eluting stents, and 50 received paclitaxel-eluting stents. RESULTS: Baseline demographics were similar among groups. One-, 6-, and 12-month outcomes, including reinfarction, death, stent thrombosis, and target vessel revascularization (TVR), were similar among groups. At 1 year, all-cause mortality was 13.3% in the BMS group and 9.2% in the DES group [P=not significant (ns)], recurrent MI was 5.3% in the BMS group vs. 4.4% in the DES group (P=ns), and TVR was 7% in the BMS group vs. 8.7% in the DES group (P=ns). CONCLUSIONS: Our data do not support the general use of DES in the setting of STEMI given similar cardiovascular outcomes among patients receiving BMS or DES, the need for long-term dual antiplatelet therapy with DES, and the possible repercussions of very late stent thrombosis. 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

Objectives : To compare long‐term clinical outcomes between intravascular ultrasound (IVUS)‐guided and angiography‐guided percutaneous coronary intervention (PCI) in a large “real world” registry. Background : The impact of IVUS‐guided PCI on clinical outcomes remains unclear. Methods : Between January 1998 and February 2006, 8,371 patients who underwent IVUS‐ (n = 4,627) or angiography‐ (n = 3,744) guided PCI were consecutively enrolled. Three‐year clinical outcomes were compared after adjustment for inverse‐probability‐of‐treatment weighting (IPTW) in the overall population and in separate populations according to stent type. Results : A crude analysis of the overall population showed that the 3‐year mortality rate was significantly lower in the IVUS‐guided group than in the angiography‐guided group (96.4% ± 0.3% vs. 93.6% ± 0.4%, log‐rank P < 0.001). When adjusted by IPTW, patients undergoing IVUS‐guided PCI remained at lower risk of mortality (hazard ratio [HR] 0.627; 95% CI 0.50–0.79, P < 0.001). Similarly, in the drug‐eluting stent (DES) population, the 3‐year risk of mortality was significantly lower in patients undergoing IVUS‐guided PCI (HR 0.46; 95% CI 0.33–0.66, P < 0.001). In contrast, IVUS‐guided PCI did not reduce the risk of mortality in the bare metal stent population (HR 0.82; 95% CI 0.60–1.10, P = 0.185). However, the risks of myocardial infarction (HR 0.95; 95% CI 0.63–1.44, P = 0.810), target vessel revascularization (HR 1.00; 95% CI 0.86–1.15, P = 0.944), and stent thrombosis (HR 0.82; 95% CI 0.53–1.07, P = 0.109) were not associated with IVUS guidance. Conclusions : IVUS‐guided PCI may reduce long‐term mortality when compared with conventional angiography‐guided PCI. This may encourage the routine use of IVUS for PCI in patients undergoing DES implantation. © 2012 Wiley Periodicals, Inc. 相似文献
