BackgroundPercutaneous coronary intervention (PCI) in patients with diabetes mellitus (DM) remains associated with inferior clinical outcomes and an increased risk of restenosis compared with non-diabetics even in the era of drug-eluting stents (DES). The outcomes with drug-coated balloons (DCBs) in diabetic patients have received limited study.MethodsWe performed a meta-analysis of all studies published between January 2000 and January 2019 reporting the outcomes with DCB vs. DES after PCI of de-novo coronary lesions in diabetic patients. Outcomes included major adverse cardiovascular events (MACE), target lesion revascularization (TLR), binary restenosis by quantitative coronary angiography (QCA), and late lumen loss (LLL).ResultsThree studies with 378 patients (440 lesions) were included in the meta-analysis. During 17.3 ± 11.3 months follow-up, DCB were associated with a similar risk of MACE (OR: 0.63, 95% CI [0.36, 1.12], p = 0.11), TLR (OR: 0.51, 95% CI [0.25, 1.06] p = 0.07), binary restenosis (OR: 0.42, 95% CI [0.09, 1.92], p = 0.26), and LLL (mean difference: −0.13 mm, 95% CI [−0.41, 0.14], p = 0.34) compared with DES.ConclusionIn diabetic patients with de-novo coronary lesions undergoing PCI, DCBs are associated with similar outcomes compared with first-generation DES, with a signal toward potential benefit in lowering target lesion revascularization. Further randomized studies are needed to compare the newer-generation DCBs and DES in this setting. 相似文献

ObjectivesThe study sought to evaluate the impact of diabetes mellitus on 3-year clinical outcome in patients undergoing drug-coated balloon (DCB) or drug-eluting stent (DES) treatment for de novo lesions.BackgroundFor treatment of de novo coronary small vessel disease, DCBs are noninferior to DES.MethodsIn this prespecified analysis of a multicenter, randomized, noninferiority trial, including 758 patients with de novo lesions in coronary vessels <3 mm who were randomized 1:1 to DCB or DES and followed over 3 years for major adverse cardiac events (MACE) (cardiac death, nonfatal myocardial infarction [MI], and target vessel revascularization [TVR]), outcome was analyzed regarding the presence or absence of diabetes mellitus.ResultsIn nondiabetic patients (n = 506), rates of MACE (DCB 13.0% vs DES 11.5%; hazard ratio [HR]: 1.24; 95% confidence interval [CI]: 0.73-2.09; P = 0.43), cardiac death (2.8% vs 2.9%; HR: 0.97; 95% CI: 0.32-2.92; P = 0.96), nonfatal MI (5.1% vs 4.8%; HR: 1.00; 95% CI: 0.44-2.28; P = 0.99), and TVR (8.8% vs 6.1%; HR: 1.64; 95% CI: 0.83-3.25; P = 0.16) were similar. In diabetic patients (n = 252), rates of MACE (19.3% vs 22.2%; HR: 0.82; 95% CI: 0.45-1.48; P = 0.51), cardiac death (8.8% vs 5.9%; HR: 2.01; 95% CI: 0.76-5.31; P = 0.16), and nonfatal MI (7.1% vs 9.8%; HR: 0.55; 95% CI: 0.21-1.49; P = 0.24) were similar in DCB and DES. TVR was significantly lower with DCBs vs DES (9.1% vs 15.0%; HR: 0.40; 95% CI: 0.17-0.94; P = 0.036; P = 0.011 for interaction).ConclusionsThe rates of MACE are similar in DCBs and DES in de novo coronary lesions of diabetic and nondiabetic patients. In diabetic patients, need for TVR was significantly lower with DCB versus DES.

Background/purposeBiodegradable-polymer (BP) and polymer-free (PF) drug eluting stents (DES) were developed to reduce the risk of delayed arterial healing observed with durable-polymer (DP) platforms. Although trials demonstrate BP-DES and PF-DES are non-inferior to DP-DES, there is limited data directly comparing these technologies. We performed a meta-analysis to assess the efficacy and safety of BP-DES versus PF-DES for the treatment of coronary artery disease.Methods/materialsElectronic searches were performed identifying randomized trials comparing BP-DES with PF-DES. Co-primary efficacy endpoints were target vessel revascularization (TVR), target lesion revascularization (TLR) and angiographic in-stent late lumen loss (LLL). Co-secondary safety endpoints were all-cause death, myocardial infarction (MI) and stent thrombosis (ST).ResultsOf 208 studies, 5 met inclusion criteria including 1975 patients. At mean follow-up (14 ± 5 months), BP-DES were associated with significantly reduced rates of TVR (OR 0.58, 95%CI 0.37–0.92, p = 0.02), TLR (4.7% vs 9.5%) (OR 0.48, 95%CI 0.31–0.75, p = 0.001) and in-stent LLL (pooled mean difference ?0.20 mm, 95%CI ?0.24 to ?0.16, p < 0.001). There was no difference in safety, including all-cause death (OR 1.24, 95%CI 0.68–2.28, p = 0.48), MI (OR 0.92, 95%CI 0.54–1.56, p = 0.75) or ST (OR 1.58, 95%CI 0.67–3.73, p = 0.30).ConclusionsThese data suggests that BP-DES are more efficacious when compared with PF-DES for the treatment of CAD. 相似文献

Background and aimClinical trials have reported lower mortality and repeated revascularization rate in diabetic patients treated with coronary artery bypass grafting (CABG) as compared to percutaneous revascularization. However, these studies were conducted in the era of bare-metal stents. Therefore, we performed a meta-analysis to compare CABG to PCI with drug-eluting stents (DES) in diabetic patients with multivessel and/or left main disease.Methods and resultsThe literature was scanned by formal search of electronic databases (Medline, EMBASE, and Cochrane databases), and major international scientific session abstracts from 2000 to 2013. Primary endpoint was mortality. A total of 14 (4 randomized and 10 non-randomized) trials were finally included, with a total of 7072 patients. Up to 5 years follow-up, CABG was associated with a reduction in mortality (7.3% vs 10.4%, OR[95%CI] = 0.65[0.55–0.77], p < 0.0001; phet = 0.00001), with similar results in both RCTs (OR[95%CI] = 0.64[0.50–0.82], p = 0.0005) and NRCTs (OR[95%CI] = 0.75[0.6–0.94)], p = 0.01) (p int = 0.93). A significant relationship was observed between risk profile and benefits in mortality with CABG (p < 0.001). CABG reduced target vessel revascularization (TVR; 5.2% vs 15.7%, OR[95%CI] = 0.30[0.25–0.36], p < 0.00001, p het = 0.02), with a relationship between risk profile and the benefits from CABG as compared to DES (p < 0.0001). CABG was associated with a lower rate of MACCE (14.9% vs 22.9%, OR[95%CI] = 0.59[0.51–0.67], p < 0.00001, p het<0.00001) but higher risk of CVA (3.6% vs 1.4%, OR[95%CI] = 2.34[1.63–3.35], p < 0.00001, p het = 0.71).ConclusionsThe present meta-analysis demonstrates that among diabetic patients with multivessel disease and/or left main disease, CABG provides benefits in mortality and TVR, especially in high-risk patients but it is counterbalanced by a higher risk of stroke. Future trials are certainly needed in the era of new DES and improved antiplatelet therapies. 相似文献

BackgroundPatients with diabetes mellitus (DM) have a high prevalence of coronary chronic total occlusions (CTOs). We conducted a systematic review and meta-analysis to characterize outcomes after CTO percutaneous coronary intervention (PCI) in patients without or with DM.MethodsPubMed, EMBASE, Cochrane, and Google Scholar were queried for studies comparing non-DM vs. DM patients undergoing attempted CTO PCI. The primary outcome was all-cause mortality at longest follow-up (at least 6 months). Secondary outcomes were major adverse cardiovascular events (MACE) which is a composite endpoint including myocardial infarction, cardiac or all-cause mortality and any revascularization in patients after CTO PCI, target vessel revascularization (TVR), myocardial infarction (MI), Japanese chronic total occlusion (J-CTO) score and prevalence of multivessel (MV) CTO disease. We used a random effects model to calculate odds ratios (ORs) and 95% confidence intervals (CIs).ResultsSixteen studies, including 2 randomized control trials and 14 observational studies, met inclusion criteria. At longest follow-up, all-cause mortality (OR 0.54 [95% CI 0.37–0.80], p < 0.0001) and MACE (OR 0.82 [95% CI 0.72–0.93], p < 0.00001) were significantly lower in non-DM CTO patients. MV CTO disease was less prevalent in patients without DM (OR 0.80 [95% CI 0.69–0.93], p = 0.004). However, there were no differences in MI, TVR and J-CTO score.ConclusionsNon-diabetics undergoing CTO PCI have lower all-cause mortality and MACE than diabetics. Future research may determine if DM control improves diabetics' CTO PCI outcomes. 相似文献

ObjectivesThis study aimed to investigate the clinical outcomes of patients presenting with recurrent drug-eluting stent (DES) in-stent restenosis (ISR) treated with a second-generation DES or with a drug-coated balloon (DCB).BackgroundTo date, there are no reports of DCB treatment and limited data with regard to the efficacy of further DES implantation for recurrent ISR.MethodsBetween January 2008 and December 2013, 171 lesions were assessed for eligibility (82 lesions in the second-generation DES group and 89 lesions in the DCB group).ResultsAcute gain was greater in the second-generation DES group (second-generation DES, 2.09 ± 0.53 mm vs. DCBs, 1.60 ± 0.62 mm, p < 0.001). The rates of major adverse cardiac events were comparable (at 1 year, DES 14.0% vs. DCBs 12.3%; at 2 years, DES 28.8% vs. DCBs 43.5%, p = 0.21). Major adverse cardiac event rates were mainly driven by target lesion revascularization (at 1 year, DES 12.5% vs. DCBs 10.9%; at 2 years, DES 27.7% vs. DCBs 38.3%; p = 0.40). Definite scaffold thrombosis occurred in 2 patients (1 patient in each group). Multivariable analysis revealed ISR recurrence within 1 year (hazard ratio: 2.43, 95% confidence interval: 1.14 to 5.18, p = 0.02) and lesion length (per 10-mm increase) (hazard ratio: 1.15, 95% confidence interval: 1.00 to 1.32, p = 0.049) to be independent predictors of TLR.ConclusionsThe results after both treatments were equivalent. ISR recurrence within 1 year of the first reintervention and lesion length were independent predictors of future target lesion revascularization. Larger studies are required to confirm the late (>1 year) differences with regard to clinical outcomes. 相似文献

BackgroundAtherosclerotic disease of the common femoral artery (CFA), commonly associated with multilevel disease affecting the femoropopliteal segment, can cause claudication or contribute to critical limb ischemia. Although endovascular therapy for the management of peripheral arterial disease (PAD) has been increasingly utilized, its role in CFA lesions remains controversial. The aim of this study was to investigate the safety and efficacy of drug (DCB) vs non drug coated balloon angioplasty (BA) at the CFA segment.MethodsIn this two-center study, we identified 154 patients treated either with DCB (n = 47) or BA (n = 107) for CFA lesions. Hazard ratios (HR) and the respective 95% confidence interval (CI) were synthesized to examine the association between the two groups in terms of target lesion revascularization (TLR), limb loss, and major adverse limb event (MALE) at 12 and 24 months of follow up.ResultsThis real-world population included a high percentage of patients with critical limb ischemia (43%) and moderate to severe lesion calcification (75%). Adjunctive atherectomy was performed in 97.9% of DCB cases (N = 46/47) and 44.7% of BA cases (N = 51/114). The overall procedural success rate was 95% without any differences between the two groups. Post-angioplasty dissections were observed in 15 cases [DCB: 8.5% (N = 4/47) vs BA: 9.7% (N = 11/113); p = .81], while distal embolization occurred in one patient in the DCB group and one in the BA group (p = .52). Provisional stenting was more commonly necessary in BA vs. DCB cases (12.3% vs 2.13%, p = .044). Physiologic assessment during follow up demonstrated a better mean 2-year ABI for the DCB group (mean: 0.9; SD: 0.2) vs BA group (mean: 0.6; SD: 0.4), although statistical significance was not reached (p = .06). No difference between the two groups was detected in terms of freedom from TLR (DCB: 75.5% vs BA: 86.8%; HR: 1.31; 95% CI: 0.46–3.67; p = .61), freedom from limb loss (DCB: 83.8% vs BA: 83.6%; HR: 1.04; 95% CI: 0.36–2.99; p = .94) or freedom from MALE (DCB: 83.5% vs BA: 78%; HR: 0.73; 95% CI: 0.26–1.99; p = .53) at 24 m of follow up. However, at the end of follow up more deaths were observed in patients treated with BA than DCB (DCB: 14.9% vs BA: 31.7%; p = .03). Patients who required provisional stenting were at higher risk for limb loss 2 years after the initial procedure (multivariate: HR: 4.54; 95% CI: 1.09–18.85; p = .04).ConclusionsBoth DCB and non-DCB strategies are effective modalities for revascularization of patients with CFA lesions. Larger prospective studies are necessary to determine the relative benefit, if any, of drug-eluting technologies for the treatment of common femoral artery disease. 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

Background
The efficacy and safety of polymer-free drug-eluting stents (DESs) in clinical practice is currently subject of debate; randomized trials (RCTs) conducted so far provided conflicting results or were underpowered to definitively address this question; we aimed to investigate the efficacy and safety profile of polymer-free vs. durable polymer DES by a comprehensive meta-analysis of RCTs.Methods
MEDLINE, Google Scholar, EMBASE and Cochrane databases were searched for RCTs comparing polymer-free to durable polymer DES. Safety endpoints at short-term (≤1 year) and long-term follow-up (>1-year) were: death, myocardial infarction (MI) and stent thrombosis (ST); main efficacy endpoints were: target lesion revascularization (TLR) and target vessel revascularization (TVR).Results
Eight RCTs including 6178 patients were included. No significant differences in mortality were observed between polymer-free and durable polymer DESs at both short- and long-follow up (OR [95% CI] = 0.79 [0.58–1.08], p = 0.14; and 0.80 [0.58–1.10], p = 0.17 respectively); polymer free and durable polymer DESs provided comparable short and long-term MI rates; at short-term: OR [95% CI] = 1.13 [0.83–1.54], p = 0.44 and at long-term: OR [95% CI] = 1.27 [0.87–1.85], p = 0.22. Similarly, these two different devices proved equally effective in regards to ST, TLR and TVR over the short and long follow-up period.Conclusions
Polymer-free DESs are as safe and effective as durable polymer DES; however, there is no evidence of any additional benefits provided by this new technology. 相似文献10.

BackgroundTAVR is an established treatment option in high and intermediate-risk patients with severe AS. There is less data regarding the efficacy of TAVR in low-risk patients. This meta-analysis evaluated efficacy and safety outcomes of transcatheter aortic valve replacement (TAVR) in comparison to surgical aortic valve replacement (SAVR) in low-risk patients with severe aortic stenosis (AS).MethodsDatabases were searched for randomized controlled trials (RCTs) that compared TAVR with SAVR for the treatment of low-risk patients with severe AS. We calculated pooled odds ratios (ORs) and 95% confidence intervals (CIs) using the random-effects model.ResultsThe final analysis included 2953 patients from 5 studies. Compared to SAVR, TAVR was associated with similar mid-term mortality [OR 0.67; 95% CI 0.37–1.21; p = 0.18], as well as similar short-term mortality [OR 0.51; 95% CI 0.24–1.11; p = 0.09]. Randomization to TAVR was associated with a reduced risk of developing acute kidney injury [OR 0.26; 95% CI 0.13–0.52; p < 0.001], short-term major bleeding [OR 0.27; 95% CI 0.12–0.60; p < 0.001] and new-onset atrial fibrillation [OR 0.17; 95% CI 0.14–0.21; p < 0.001]. However, TAVR was associated with a higher risk of requiring permanent pacemaker implantation [OR 4.25; 95% CI 1.86–9.73; p < 0.001]. There was no significant difference in the risk of myocardial infarction, stroke, endocarditis or aortic valve re-intervention between the two groups.ConclusionsOur meta-analysis showed that TAVR has similar clinical efficacy to SAVR, with a more favorable safety profile, in patients with severe AS who are at low-surgical risk. 相似文献

BackgroundCoronary stent neoatherosclerosis, thrombosis, and restenosis remain significant concerns with new-generation drug-eluting stents (DES). The Dual-Therapy CD34 antibody-covered sirolimus-eluting stent [dual therapy stent (DTS)] is a sirolimus-eluting stent with CD34 antibodies immobilized on its luminal surface to capture circulating endothelial progenitor cells and promote early endothelialization. We conducted a meta-analysis to determine whether the DTS was superior to standard DES.MethodsWe conducted a comprehensive search for controlled randomized and non-randomized studies. We presented data using risk ratios (95% confidence intervals) and measured heterogeneity using Higgins' I2.ResultsFive studies with a low risk of bias met the inclusion criteria, with a total of 1884 patients in the DTS and 1819 in standard DES arms. There was no difference between the 2 arms in the following 1-year outcomes: cardiac death [1% vs 0.9% RR 1.13 (95% CI 0.49–2.62) I2 = 0%], target lesion failure [6.2% vs 5.3% RR 1.12 (0.80–1.58) I2 = 0%], target lesion revascularization (TLR) [4.9% vs 3.4% RR 1.40 (0.93–2.10) I2 = 15%], target vessel failure [8.2% vs 6.1% RR 1.24 (0.75–2.04) I2 = 0%], target vessel myocardial infarction [1.1% vs 1.8% RR 0.73 (0.19–2.90) I2 = 62%] and stent thrombosis [0.4% vs 0.6% HR 0.85 (0.27–2.62) I2 = 0%]. However, compared with second-generation DES (EES and ZES), the DTS had significantly higher one-year TLR [5% vs. 3.1% RR 1.58 (1.02–2.46) P = 0.04 I2 = 0%].ConclusionOne-year TLR was significantly higher in the DTS arm compared with second-generation DES. There was no difference in the other 1-year clinical outcomes compared with standard DES. 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

BackgroundThe optimal stent for use in saphenous vein graft (SVG) intervention is still debatable. Multiple randomized trials have compared drug-eluting stents (DES) to bare metal stents (BMS) in SVG interventions with conflicting results.MethodsAuthors searched the online databases for randomized controlled trials (RCTs) comparing DES to BMS in SVG percutaneous coronary interventions (PCI). We performed a meta-analysis using a random effects model to calculate the odds ratio for outcomes of interest.ResultsAuthors studied six RCTs that included 1592 patients undergoing PCI of SVG. The mean follow up was 42 months. Patients mean age was the same in both groups: 70.3 years in the DES group (approximately 93.3% male) and 70.3 years in the BMS group (approximately 93.8% male). Vein graft age was 13.4 years in the DES PCI arm vs. 13.4 years in the BMS PCI arm. Four of the six trials reported data on embolic protection device use: 67% (303/452) in the DES arm vs. 67.9% (309/455) in the BMS arm. The primary outcome of long-term all-cause mortality was not different between DES vs. BMS (15.2% vs. 14.1%, OR 1.12, 95% CI 0.67–1.88; P = 0.66). Secondary outcomes were also similar between DES and BMS: major adverse cardiovascular events (31.6% vs. 33.1%, OR 0.79, 95% CI 0.45–1.38; P = 0.41); cardiac death (9% vs. 8.6%, OR 1.12, 95% CI 0.55–2.30; P = 0.75); myocardial infarction (8% vs. 9.5%, OR 0.84, 95% CI 0.47–1.51; P = 0.57); target lesion revascularization (16.4% vs. 14.4%, OR 0.98, 95% CI 0.50–1.92; P = 0.95); and target vessel revascularization (19% vs. 19.4%, OR 0.75, 95% CI 0.41–1.34; P = 0.33).ConclusionAt a mean follow-up of 42 months, no difference was observed in clinical outcomes between DES and BMS in SVG interventions. 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

BackgroundDrug-coated balloon (DCB) angioplasty for side branches with main branch stenting is effective for bifurcation lesions and reduces late lumen loss (LLL) in side branches. However, the predictors and clinical implications of LLL after DCB angioplasty are largely unexplored.MethodsAmong 181 patients undergoing DCB angioplasty for side branches with drug-eluting stent implantation for main branches between 2016 and 2018, we enrolled 138 patients (138 lesions) undergoing follow-up coronary angiography within 1 year. The 1-year cumulative rates of target lesion revascularization (TLR) and major adverse cardiac events (MACE: defined as a composite of all-cause death, myocardial infarction, and TLR) were compared between patients with late lumen gain (LLG) (LLG group) and those with LLL (LLL group).ResultsThe binary restenosis rate of the side branch was 8.0% (11 lesions), mean LLL was −0.14 ± 0.43 mm, and LLG was observed in 99 lesions (71.7%). The DCB size/reference vessel diameter ratio showed mild discrimination (area under the curve, 0.60; 95% confidence interval, 1.2–65.0; p = 0.03) for predicting the side branch progression. The 1-year cumulative rates of MACE and TLR were not significantly different but numerically lower in the LLG group than in the LLL group (2.0% vs. 7.8%, p = 0.11 and 2.0% vs. 7.7%, p = 0.11, respectively). Lumen regression after DCB angioplasty for side branches are associated with improved clinical outcomes. Conclusions: The DCB size relative to the reference vessel diameter is a predictor of late lumen enlargement in side branches. 相似文献

Large interests have been focused on the role of drug-eluting stents in the setting of ST-segment elevation myocardial infarction (STEMI) and concerns have emerged regarding an higher risk of stent thrombosis. Aim of the current study was to perform a meta-analysis using individual patient data to evaluate the long-term safety and effectiveness of sirolimus-eluting stent (SES) as compared to paclitaxel-eluting stent (PES) in patients undergoing primary percutaneous coronary intervention (PCI) for STEMI. The literature was scanned by formal searches of electronic databases (MEDLINE and CENTRAL). We examined all completed randomized trials of SES versus PES for STEMI. No language restriction was applied. Primary study endpoint was the occurrence of major adverse cardiac events (MACE). Secondary endpoints were the occurrence of death, reinfarction, stent thrombosis, target-vessel revascularization (TVR). Individual patient data were obtained from 4 out of 5 trials identified, including a total of 1,000 patients, 504 (50.4 %) randomized to SES and 496 (49.6 %) randomized to PES. At long-term follow-up (1,021 [372–1,351] days), no difference was observed between SES and PES in terms of TVR (10 vs 11.6 %, HR [95 % CI 0.73 [0.45–1.16], p = 0.18, p het = 0.92]) (primary endpoint) or death (9.4 vs 10.4 %, HR [95 % CI 0.95 [0.58–1.54], p = 0.82, p het = 0.89]), reinfarction (8.2 vs 10.4 %, HR [95 % CI 0.91 [0.53–1.57], p = 0.73, p het = 0.83]), stent thrombosis (7.4 vs 4.6 %, HR [95 % CI 1.04 [0.55–2.05], p = 0.92, p het = 0.65]), and MACE (10 vs 13.6 %, HR [95 % CI 0.86 [0.63–1.18], p = 0.36, p het = 0.84]) (secondary endpoints). The present pooled patient-level meta-analysis demonstrates that, among STEMI patients undergoing primary PCI, SES and PES are associated with a similar outcome at long-term follow-up, in terms of death, reinfarction, stent thrombosis, TVR and MACE. 相似文献

Objectives: To evaluate outcome of patients undergoing sirolimus‐eluting stent (SES) as compared to bare‐metal stent (BMS) implantation during primary angioplasty for ST‐segment elevation myocardial infarction (STEMI). Background: The role of SES in primary percutaneous coronary intervention setting is still debated. Methods: We searched Medline, EMBASE, CENTRAL, scientific session abstracts, and relevant Websites for studies in any language, from the inception of each database until October 2008. Only randomized clinical trials with a mean follow‐up period >6 months and sample size >100 patients were included. Primary endpoint for efficacy was target‐vessel revascularization (TVR) and primary endpoint for safety was stent thrombosis. Secondary endpoints were cardiac death and recurrent myocardial infarction (MI). Results: Six trials were included in the meta‐analysis, including 2,381 patients (1,192 randomized to SES and 1,189 to BMS). Up to 12‐month follow‐up, TVR was significantly lower in patients treated with SES as compared to patients treated with BMS (4.53% vs. 12.53%, respectively; odds ratio [OR] 0.33; 95% confidence interval [CI] 0.24–0.46; P < 0.00001). There were no significant differences in the incidence of stent thrombosis (3.02% vs. 3.70%, OR = 0.81 [95% CI, 0.52–1.27], P = 0.81), cardiac death (2.77% vs. 3.28%, OR = 0.84 [95% CI, 0.52–1.35], P = 0.47), and recurrent MI (2.94% vs. 4.04%, OR = 0.71 [95% CI, 0.45–1.11], P = 0.13) between the two groups. Conclusion: SES significantly reduces TVR rates as compared to BMS in STEMI patients up to 1 year follow‐up. Further studies with larger population and longer follow‐up time are needed to confirm our findings. © 2009 Wiley‐Liss, Inc. 相似文献

ObjectivesThis study sought to compare the performance of a novel drug-coated balloon (DCB) (Elutax SV, Aachen Resonance, Germany), with an everolimus-eluting stent (EES) (Abbott Vascular, Santa Clara, California) in patients with de novo lesions.BackgroundSmall vessel coronary artery disease (SVD) represents one of the most attractive fields of application for DCB. To date, several devices have been compared with drug-eluting stents in this setting, with different outcomes.MethodsThe PICCOLETO II (Drug Eluting Balloon Efficacy for Small Coronary Vessel Disease Treatment) trial was an international, investigator-driven, multicenter, open-label, prospective randomized controlled trial where patients with de novo SVD lesions were randomized to DCB or EES. Primary study endpoint was in-lesion late lumen loss (LLL) at 6 months (independent core laboratory), with the noninferiority between the 2 arms hypothesized. Secondary endpoints were minimal lumen diameter, percent diameter stenosis at angiographic follow-up, and the occurrence of major adverse cardiac events at 12 months.ResultsBetween May 2015 and May 2018, a total of 232 patients were enrolled at 5 centers. After a median of 189 (interquartile range: 160 to 202) days, in-lesion LLL was significantly lower in the DCB group (0.04 vs. 0.17 mm; p = 0.001 for noninferiority; p = 0.03 for superiority). Percent diameter stenosis and minimal lumen diameter were not significantly different. At 12-month clinical follow-up, major adverse cardiac events occurred in 7.5% of the DES group and in 5.6% of the DCB group (p = 0.55). There was a numerically higher incidence of spontaneous myocardial infarction (4.7% vs. 1.9%; p = 0.23) and vessel thrombosis (1.8% vs. 0%; p = 0.15) in the DES arm.ConclusionsIn this multicenter randomized clinical trial in patients with de novo SVD lesions, a new-generation DCB was found superior to EES in terms of LLL as the angiographic pattern and comparable in terms of clinical outcome.

We compare real‐world, extended target vessel revascularization (TVR)‐free survival following percutaneous coronary intervention (PCI) for patients receiving either sirolimus‐eluting stents (SES) or paclitaxel‐eluting stents (PES) following an index drug‐eluting stent (DES) supported procedure. We analyzed 2,363 consecutive patients having first DES‐supported PCI at receiving PES (n = 1,012) or SES (n = 1,332) from April 2004 to July 2006. Baseline clinical and procedural characteristics and in‐hospital outcomes were recorded during the time of the index procedure and extended clinical outcomes data were obtained thereafter. TVR and all cause mortality were identified during the study period. Adjusted Kaplan‐Meier and Cox's proportional hazard survival methods were performed. TVR‐free survival at 2.3 years was 91.3% for SES compared with 88.9% for PES (P = 0.06). Kaplan‐Meier survival curves did not significantly differ (adjusted hazard ratio ?1.39 [95% CI 0.99–1.97]) between the SES and PES patient cohorts. TVR was similar between the stent platforms at one (96.6% for SES [95% CI 95.3–97.6] vs. 95.7% for PES [95% CI 94.1–96.9]) and two (95.0%[95% CI 93.0–96.4] for SES vs. 93.7% for PES [95% CI 91.6–95.3]) years. Overall survival at 2 years was 96.2% for SES (95% CI 94.7–97.3) and 95.3% for PES (95% CI 93.7–96.5). SES and PES drug‐eluting stent platforms have good and similar extended outcomes in this real world registry of unselected patients having PCI. (J Interven Cardiol 2010;23:167‐175) 相似文献

Background and aimsStudies have linked several metabolites to the risk of coronary heart disease (CHD) among Western populations, but prospective studies among Asian populations on the metabolite–CHD association remain limited.Methods and ResultsWe evaluated the association of urinary metabolites with CHD risk among Chinese adults in a nested case–control study of 275 incident cases and 275 matched controls (127 pairs of men and 148 pairs of women). Fifty metabolites were measured by a predefined metabolomics panel and adjusted using urinary creatinine. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs). After adjusting for traditional CHD risk factors, urinary tryptophan showed a positive association with incident CHD: OR (95% CI) for the highest vs. lowest quartiles was 2.02 (1.15–3.56) among all study participants (p-trend = 0.02). The tryptophan–CHD association was more evident among individuals with dyslipidemia than among those without the condition (OR [95% CI] for the highest vs. lowest quartiles = 3.90 [1.86–8.19] and 0.74 [0.26–2.06], respectively; p-interaction<0.01). Other metabolites did not show significant associations with CHD risk among all study participants. However, a positive association of methionine with CHD risk was observed only among women (OR [95% CI] for the highest vs. lowest quartiles = 2.77 [1.17–6.58]; p-interaction = 0.03), and an inverse association of inosine with CHD risk was observed only among men (OR [95% CI] for the highest vs. lowest quartiles = 0.29 [0.11–0.81]; p-interaction = 0.04).ConclusionElevated urinary tryptophan may be related to CHD risk among Chinese adults, especially for those with dyslipidemia. 相似文献
