药物洗脱支架
  • 文章类型: Journal Article
    在接受经皮冠状动脉介入治疗(PCI)的患者中,药物洗脱支架(DES)是目前的护理标准。支架设计和合金成分,药物洗脱聚合物涂层的生物相容性,抗增殖剂的性质和释放是影响DES性能的三个主要特征。Cre8(Alvimedica,伊斯坦布尔,Turkey)是一种无聚合物的双亲洗脱支架(PF-AES)。在这项研究中,我们旨在研究Cre8DES在日常心脏病学实践中的临床疗效和安全性.
    出现慢性冠脉综合征(CCS)或急性冠脉综合征(ACS)包括不稳定型心绞痛(USAP)的患者,本研究回顾性分析2015年12月至2016年期间有或无ST段抬高的心肌梗死,并采用Cre8DES进行PCI治疗.
    在2015年12月至2016年之间,在单个中心接受Cre8DES治疗的664例患者的808个病变被纳入该回顾性分析。研究组的平均年龄为60岁(33至93岁),主要由男性患者组成(79.4%)。中位随访时间为487天(min:30days,max:919天),所有患者中有三分之二患有ACS。在大多数患者中,罪魁祸首是左前降支(LAD)(40.5%)和右冠状动脉(RCA)(25.9%)。手术成功率为97.3%。根据美国心脏病学会/美国心脏协会(ACC/AHA)冠状动脉病变分类,大多数病变为B1型(40.6%)。装置定位的主要终点定义为靶病变失效(TLF)发生在808处病变中的52处(6.4%)。主要安全终点为20例患者的心源性死亡(3.0%)和2例患者的靶血管心肌梗死(0.3%)。作为主要安全终点,29例患者(4.4%)发生靶血管血运重建(TVR)。多变量逻辑回归分析显示,糖尿病和射血分数是死亡率和设备导向的主要终点的预测因子。
    该试验揭示了Cre8支架在现实世界实践中的临床疗效和安全性。面向装置的主要终点与之前随机研究相似,在性质上开放标签,并显示了Cre8支架对最新一代DES的有效性和安全性。
    UNASSIGNED: In patients undergoing percutaneous coronary intervention (PCI), drug eluting stents (DES) are currently the standard of care. Stent design and alloy composition, biocompatibility of the drug-eluting polymer coating, the antiproliferative agent properties and release are the three main characteristics that affects DES performance. Cre8 (Alvimedica, Istanbul, Turkey) is a polymer-free amphilimus-eluting stents (PF-AES). In this study, we aimed to investigate the clinical efficacy and safety of Cre8 DES in daily cardiology practice.
    UNASSIGNED: Patients presenting with chronic coronary syndrome (CCS) or acute coronary syndrome (ACS) including unstable angina pectoris (USAP), myocardial infarction with and without ST-segment elevation and treated with PCI using Cre8 DES between December 2015 and 2016 were retrospectively analyzed in this study.
    UNASSIGNED: Between December 2015 and 2016, 808 lesions of 664 patients treated with Cre8 DES in a single center were included in this retrospective analysis. The mean age of study group was 60 years (between 33 and 93 years) and were predominantly consisting of male patients (79.4%). The median follow-up duration was 487 days (min: 30 days, max: 919 days) and two-thirds of all patients presented with ACS. The culprit lesion was on left anterior descending artery (LAD) (40.5%) and right coronary artery (RCA) (25.9%) in most of the patients. The procedural success rate was 97.3%. Most of the lesions were type B1 (40.6%) according to American College of Cardiology/American Heart Association (ACC/AHA) coronary lesion classification. The device oriented primary end-point defined as target lesion failure (TLF) occurred in 52 (6.4%) of 808 lesions. The primary safety end-point was cardiac death in 20 patients (3.0%) and target vessel myocardial infarction in 2 patients (0.3%). Target vessel revascularization (TVR) occurred in 29 patients (4.4%) as primary safety endpoint. Multivariable logistic regression analysis revealed diabetes mellitus and ejection fraction as the predictors of mortality and device oriented primary end-point.
    UNASSIGNED: This trial revealed clinical efficacy and safety of Cre8 stents in real world practice. Device oriented primary end points were similar with previous studies which are randomized, open label in nature and showed the efficacy and safety of Cre8 stent towards latest generation DES.

    背景:在无保护的左主远端分叉病变(ULMD)的老年人中,经皮冠状动脉介入治疗(PCI)通常被选择为首选治疗策略,因为冠状动脉旁路移植术的围手术期风险较高,因为它们有大量的合并症.此外,最近的一些论文报道,老年营养风险指数(GNRI)也与老年患者介入治疗后的临床结局密切相关.
    目的:我们评估老年患者ULMDPCI后的临床结局和GNRI的影响。
    方法:我们从MITO注册中确定了669例非透析患者接受了ULMD的当前一代药物洗脱支架治疗。我们将患者分为以下2组:老年组(n=240,年龄≥75)和青年组(n=429,年龄<75)。此外,我们可以计算GNRI,并根据GNRI的中位数将老年组分为2组。主要终点是全因死亡率。
    结果:老年组的全因死亡率明显高于[调整后的风险比(HR)2.37;95%置信区间(CI),1.40-4.02;p=0.001]。与其他两组相比,低GNRI老年人组的全因死亡率显着升高(低GNRI老年人的调整后HR:3.56,95CI(1.77-7.14),p<0.001)。两组的心血管死亡率相当。老年组TLR率显着降低(校正HR0.57;95%CI,0.34-0.97;p=0.035)。
    结论:与年轻人相比,老年人因ULMDPCI术后全因死亡率较高。尤其是,GNRI较低的老年人与较差的结局极为相关.
    BACKGROUND: In the elderly people with unprotected left main distal bifurcation lesions (ULMD), percutaneous coronary intervention (PCI) is often selected as first choice treatment strategy because of perioperative high risk of coronary artery bypass graft surgery due to their large number of comorbidities. Also, some recent papers reported that geriatric nutritional risk index (GNRI) is also strongly associated with clinical outcomes after interventional procedures in elderly patients.
    OBJECTIVE: We assessed clinical outcomes after PCI for ULMD and the impact of GNRI in elderly patients.
    METHODS: We identified 669 non dialysis patients treated with current generation drug-eluting stent for ULMD from MITO registry. We divided the patients to the following 2 groups; elderly group (n = 240, age ≥75) and young group (n = 429, age <75). Additionally, we could calculate GNRI and divided elderly group into 2 group based on the median value of the GNRI. The primary endpoint was all-cause mortality.
    RESULTS: All-cause mortality was significantly higher in elderly group [adjusted hazard ratio (HR) 2.37; 95% confidence interval (CI), 1.40-4.02; p = 0.001]. All-cause mortality was significantly higher in low GNRI elderly group compared to other 2 groups (Adjusted HR of elderly with low GNRI: 3.56, 95%CI (1.77-7.14), p < 0.001). Cardiovascular mortality was comparable between two groups. TLR rate was significantly lower in elderly group (adjusted HR 0.57; 95% CI, 0.34-0.97; p = 0.035).
    CONCLUSIONS: The elderly had higher all-cause mortality after PCI for ULMD compared to young people. Especially, the elderly with low GNRI were extremely associated with poorer outcomes.

    背景:药物洗脱支架(DES)用于治疗下肢动脉疾病。在DES治疗期间,偶尔会发生动脉瘤变性,特别是含氟聚合物基DES。然而,在下肢区域很少报道DES放置后假性动脉瘤的发生率,尽管有一些关于冠状动脉区域DESpla水泥后假性动脉瘤形成的报道。
    方法:我们报告一例64岁男性透析后出现发热和左手疼痛的病例。血培养诊断菌血症,入院后,他的右大腿内侧出现疼痛。在先前放置的DES的近端右股浅动脉(SFA)中观察到假性动脉瘤。菌血症被认为是由左肱浅动脉假性动脉瘤引起的,抗生素治疗后切除左肱浅动脉假性动脉瘤。右侧SFA假性动脉瘤入院后迅速扩张,但感染控制后扩张率降低。第一次入院七个月后,使用利福平浸泡的Dacron移植物,对左侧SFA的假性动脉瘤进行了再移动,并进行了原位血运重建.
    结论:尽管在下肢区域放置DES后假性动脉瘤很少见,菌血症患者必须考虑。
    BACKGROUND: Drug-eluting stents (DES) are used to treat lower extremity arterial disease. During DES treatment, aneurysmal degeneration occasionally occurs, especially with fluoropolymer-based DES. However, the incidence of pseudoaneurysms after DES placement is rarely reported in the lower extremity region, although there have been several reports on pseudoaneurysm formation after DES pla-cement in the coronary artery region.
    METHODS: We report the case of a 64-year-old man who presented with fever and pain in his left hand after dialysis. Bacteremia was diagnosed by blood culture, and after admission, he developed pain on the medial side of the right thigh. A pseudoaneurysm was observed in the right superficial femoral artery (SFA) at the proximal end of a previously placed DES. The bacteremia was thought to have been caused by a pseudoaneurysm of the left superficial brachial artery, and the pseudoaneurysm of the left superficial brachial artery was removed after antibiotic treatment. The pseudoaneurysm of the right SFA rapidly expanded after admission, but the expansion rate was reduced after infection control. Seven months after the first admission, the pseudoaneurysm of the left SFA was re-moved and in situ revascularization performed using a rifampicin-soaked Dacron graft.
    CONCLUSIONS: Although pseudoaneurysm after DES placement in the lower extremity region is rare, it must be considered in patients with bacteremia.

    尽管已知血浆致动脉粥样硬化指数(AIP)与冠状动脉疾病(CAD)和动脉粥样硬化的关系,AIP与支架内再狭窄(ISR)之间的关系尚不清楚.我们旨在研究使用药物洗脱支架(DES)治疗的稳定型心绞痛(SAP)患者的AIP与ISR之间的关系。
    在这项观察性和回顾性研究中,在2015年1月至2019年11月期间评估了稳定型心绞痛后有DES植入史的患者。608名符合条件的患者被分为ISR+(n=241)和ISR-(n=367)。ISR定义为存在50%或更大的狭窄。AIP定义为log[TG/HDL-C]。
    发生ISR的患者的AIP水平明显高于未发生ISR的患者(分别为0.33[0.15-0.52]和0.06[-0.08-0.21],p<0.001)。预测ISR的AIP水平的AUC值为0.746(p<0.001)。多因素Logistic回归分析显示,AIP,糖尿病,较高的LDL-C水平和较低的LVEF值与ISR独立相关.
    多变量分析显示,AIP与ISR具有很强的独立相关性。使用这种新颖的廉价且易于计算的指数可以在接受DES治疗的SAP患者中提供ISR的早期识别。
    UNASSIGNED: Although the association of Atherogenic index of plasma (AIP) with coronary artery disease (CAD) and atherosclerosis is known, the relationship between AIP and in-stent restenosis (ISR) remains unclear. We aimed to investigate the relationship between AIP and ISR in patients with stable angina pectoris (SAP) treated with drug-eluting stent (DES).
    UNASSIGNED: Patients with a history of DES implantation following stable angina were evaluated between January 2015 and November 2019 in this observational and retrospective study. 608 eligible patients were dichotomized into ISR+ (n=241) and ISR- (n=367). ISR was defined as the presence of 50% or greater stenosis. AIP was defined as log [TG/HDL-C].
    UNASSIGNED: AIP levels were significantly higher in patients who developed ISR compared with those who did not (0.33 [0.15-0.52] vs 0.06 [-0.08-0.21] respectively, p<0.001). The AUC value of AIP levels for predicting ISR was 0.746 (p<0.001). Multivariate logistic regression analysis revealed that AIP, diabetes mellitus, higher LDL-C levels and lower LVEF values were independently associated with ISR.
    UNASSIGNED: Multivariate analysis revealed that AIP was strongly independently associated with ISR. Using this novel inexpensive and easily calculable index may provide early recognition of ISR in patients with SAP who were treated with DES.

    接受经皮冠状动脉介入治疗(PCI)的患者中有很大一部分没有标准的可改变的心血管危险因素(SMuRF):高血压,糖尿病,高胆固醇血症和吸烟。该分析的目的是根据SMuRFs的数量比较PCI后的临床结果。
    根据SMuRF的数量:0、1、2或3-4对具有PCI适应症的患者进行分层。主要结果是靶病变失败(TLF),心脏死亡的复合物,靶血管相关心肌梗死或临床驱动的靶病变1年血运重建。进行反向加权倾向评分(IWPS)调整以调整基线特征的差异。
    SMuRF的患病率为:0SMuRF16.4%;1SMuRF27.8%;2SMuRF34.7%和3-4SMuRF21.1%。没有SMuRF的患者更年轻,更有可能是男性,患有不太复杂的冠状动脉疾病。TLF的发生率随SMuRFs数量的增加而增加:2.65%,2.75%,3.23%,和4.24%,Ptrend<0.001。与没有SMuRF的患者相比,具有3-4个SMuRF的患者的TLF的相对风险(RR)高60%(95%置信区间1.32-1.93,p<0.01)。IWPS后趋势仍然存在(P趋势<0.01),TLF率为2.88%,2.64%,2.88%和3.65%。TLF的RR高出27%(95%CI1.05-1.53,p<0.01)。
    1年临床事件的发生率随着SMuRF数量的增加而增加。虽然没有SMuRF的患者具有相对有利的风险特征,需要更多的研究来优化大多数患者的治疗管理.
    UNASSIGNED: A substantial proportion of the patients undergoing percutaneous coronary intervention (PCI) have none of the of standard modifiable cardiovascular risk factors (SMuRFs): hypertension, diabetes, hypercholesterolaemia and smoking. The aim of this analysis was to compare clinical outcomes after PCI according to the number of SMuRFs.
    UNASSIGNED: Patients with an indication for a PCI were stratified based upon the number of SMuRFs: 0, 1, 2 or 3-4. The primary outcome was target lesion failure (TLF), a composite of cardiac death, target vessel-related myocardial infarction or clinically driven target lesion revascularization at 1-year. Inverse weighted propensity score (IWPS) adjustment was performed to adjust for differences in baseline characteristics.
    UNASSIGNED: The prevalence of SMuRFs was: 0 SMuRF 16.4 %; 1 SMuRF 27.8 %; 2 SMuRFs 34.7 % and 3-4 SMuRFs 21.1 %. Patients without SMuRFs were younger, more likely to be male and had less complex coronary artery disease. The incidence of TLF increased with the number of SMuRFs: 2.65 %, 2.75 %, 3.23 %, and 4.24 %, Ptrend < 0.001. The relative risk (RR) for a TLF was 60 % higher (95 % confidence interval 1.32-1.93, p < 0.01) for patients with 3-4 SMuRFs compared to patients without SMuRFs. The trend remained (Ptrend < 0.01) after IWPS with TLF rates of 2.88 %, 2.64 %, 2.88 % and 3.65 %. The RR for a TLF was 27 % higher (95 % CI 1.05-1.53, p < 0.01).
    UNASSIGNED: The incidence of clinical events at 1-year increased with the number of SMuRFs. While patients without SMuRFs have a relatively favourable risk profile, more research is needed to optimize therapeutic management in the majority of patients.

    有安装数据支持使用药物涂层球囊(DCB)不仅用于治疗支架内再狭窄(ISR),而且在天然冠状动脉疾病中也是如此。到目前为止,紫杉醇涂层的球囊代表了主要的DCB。SeQuent®晶体西罗莫司涂层球囊(SCB)(B.BraunMedicalInc,德国)代表了一种新颖的DCB,这允许莫司药物的持续释放。我们评估了它在所有参与者中的表现,包括复杂的冠状动脉病变。
    接受SeQuent®SCB治疗的连续患者从前瞻性SIROOP注册(NCT04988685)进行分析。我们评估了临床结果,包括主要不良心血管事件(MACE),靶病变血运重建(TLR),目标血管心肌梗死(TV-MI)和心血管死亡。独立判定血管造影图和结果。
    从2021年3月到2023年3月,我们招募了126名患者和病变,其中100人(79%)使用“仅DCB”策略治疗,26人(21%)使用混合方法(DES+DCB)治疗。平均年龄68±10岁,48例(38%)患者患有急性冠脉综合征。关于病变特征,ISR治疗27例(21%),11例(9%)行CTO-PCI,59例(47%)血管中度至重度钙化。手术成功率为100%。中位随访时间为12.7(IQR12;14.2)个月,5例患者发生MACE(4.3%)。未观察到急性血管闭合。
    我们的数据表明,在患有复杂冠状动脉病变的所有人群中,使用这种新型结晶SCB治疗后,有希望的结果。这些结果需要随机试验的进一步研究。
    UNASSIGNED: There is mounting data supporting the use of drug-coated balloons (DCB) not only for treatment of in-stent restenosis (ISR), but also in native coronary artery disease. So far, paclitaxel-coated balloons represented the mainstay DCBs. The SeQuent® crystalline sirolimus-coated balloon (SCB) (B.Braun Medical Inc, Germany) represents a novel DCB, which allows a sustained release of the limus-drug. We evaluated its performance in an all-comer cohort, including complex coronary lesions.
    UNASSIGNED: Consecutive patients treated with the SeQuent® SCB were analyzed from the prospective SIROOP registry (NCT04988685). We assessed clinical outcomes, including major adverse cardiovascular events (MACE), target lesion revascularization (TLR), target vessel myocardial infarction (TV-MI) and cardiovascular death. Angiograms and outcomes were independently adjudicated.
    UNASSIGNED: From March 2021 to March 2023, we enrolled 126 patients and lesions, of which 100 (79%) treated using a \"DCB-only\" strategy and 26 (21%) with a hybrid approach (DES + DCB). The mean age was 68 ± 10 years, 48 (38%) patients had an acute coronary syndrome. Regarding lesion characteristics, ISR was treated in 27 (21%), 11 (9%) underwent CTO-PCI and 59 (47%) of the vessels were moderate to severe calcified. Procedural success rate was 100%. At a median follow-up time of 12.7 (IQR 12; 14.2) months, MACE occurred in 5 patients (4.3%). No acute vessel closure was observed.
    UNASSIGNED: Our data indicates promising outcomes following treatment with this novel crystalline SCB in an all-comer cohort with complex coronary lesions. These results require further investigation with randomized trials.

  • 文章类型: Randomized Controlled Trial
    背景:患有2型糖尿病(T2D)的受试者支架内再狭窄和支架内血栓形成的风险更高。已提出胰高血糖素样肽-1受体(GLP-1R)的活化对脉管系统诱导若干作用,其可降低血管成形术后支架失效的风险。这项研究的目的是评估GLP-1R激动剂艾塞那肽对T2D患者现代药物洗脱支架(DES)内皮化的影响。
    方法:38名符合DES植入血运重建的T2D患者随机接受艾塞那肽(每周一次)加标准治疗,或单独的标准治疗。12周后,我们进行了新的冠状动脉造影,以通过光学相干断层扫描评估支柱覆盖百分比(主要终点)和新动脉粥样硬化的存在.这项研究得到了斯德哥尔摩伦理审查委员会的批准。
    结果:两组的基线临床特征平衡良好。艾塞那肽组的支柱覆盖率为95%(88.7-98.5%),对照组为91.4%(88.8-98.5%)(p=0.692)。两组新生内膜厚度均无显著差异(两组均为0.2mm,p=0.471),或新内膜的最大支架内阻塞(艾塞那肽组15.5%vs对照组14.7%,p=0.801)。两组间靶病变血运重建率无显著差异(p=0.224)。
    结论:艾塞那肽治疗12周并未显著改善T2D患者的支架覆盖率。两组之间新动脉粥样硬化的发生没有显着差异。
    背景:该研究在www注册。
    结果:gov(重建研究,NCT02621489)。
    Subjects with type 2 diabetes (T2D) have a higher risk of in-stent restenosis and stent thrombosis. The activation of the glucagon-like peptide-1 receptor (GLP-1R) has been suggested to induce several effects on the vasculature that may reduce the risk of stent failure following an angioplasty. The aim of this study is to evaluate the effect of the GLP-1R agonist exenatide on endothelialization of a modern drug-eluting stent (DES) in subjects with T2D.
    38 subjects with T2D who were eligible for revascularization with implantation of DES were randomized to treatment with exenatide (once weekly) plus standard treatment, or to standard treatment alone. After 12 weeks, a new coronary angiography was performed to evaluate the percentage of strut coverage (primary endpoint) and the presence of neo-atherosclerosis by optical coherence tomography. This study was approved by the Stockholm\'s Ethical Review Board.
    The two groups were well balanced regarding baseline clinical characteristics. Strut coverage was 95% (88.7-98.5%) in the exenatide group and 91.4% (88.8-98.5%) in the control group (p = 0.692). There were no significant differences between groups neither in the thickness of neo-intima (0.2 mm in both groups, p = 0.471), nor the maximal in-stent obstruction by neo-intima (15.5% in exenatide group vs 14.7% in control group, p = 0.801). No significant differences were detected in the rate of target lesion revascularization between groups (p = 0.224).
    Twelve weeks treatment with exenatide did not lead to a significantly better stent coverage in people with T2D. No significant differences in the occurrence of neo-atherosclerosis were detected between groups.
    The study was registered at www.

    目的:我们旨在对药物涂层球囊(DCB)-仅血管成形术与药物洗脱支架(DES)进行成本分析,用于所有血管大小和所有临床适应症的从头疾病。
    背景:DCB血管成形术是治疗冠状动脉疾病的新兴技术。与第二代DES相比,缺乏有关仅DCB血管成形术治疗从头冠状动脉疾病的成本效益的数据。
    方法:我们比较了首次出现ST段抬高型心肌梗死的DCB或DES患者的总费用,非ST段抬高型心肌梗死,或由于2018年1月1日至2019年11月15日之间的新发疾病引起的稳定型心绞痛。我们将总成本定义为(1)程序设备-成本的总和,(2)程序性人员成本,(3)经皮冠状动脉介入治疗后住院费用,(4)抗血小板方案成本。进行了成本最小化分析以比较DCB和DES的成本。
    结果:我们介绍了1952年的所有参与者,连续患者;902例(1064个病灶)接受DCB治疗,1050例(1236个病灶)接受DES治疗。在DCB组中,每位患者的费用估计为9.02英镑(3153.00英镑与3143.98英镑)。然而,经计算,DCB组的每个病灶治疗费用便宜15.51英镑(3007.56英镑与3023.07英镑)。无论长期抗血小板药物的持续时间如何,结果都是一致的。
    结论:我们比较了仅DCB血管成形术和DES血管成形术的成本-效果,结果显示每个患者和每个病变的结果没有差异,因此选择DCB或DES的决定不应涉及成本。
    We aimed to perform a cost analysis of drug coated balloon (DCB)-only angioplasty versus drug eluting stent (DES), for de novo disease of all vessel sizes and all clinical indications.
    DCB angioplasty is an emergent technology for the treatment of coronary artery disease. There is lack of data regarding the cost-effectiveness of DCB-only angioplasty for treatment of de novo coronary artery disease as compared with second generation DES.
    We compared total costs of patients treated with DCB or DES for first presentation of ST-elevation myocardial infarction, non-ST-elevation myocardial infarction, or stable angina due to de novo disease between January 1, 2018 and November 15, 2019. We defined total cost as the sum of (1) procedural devices-cost, (2) procedural staff-cost, (3) post-percutaneous coronary intervention hospital stay cost, and (4) antiplatelet regime cost. A cost minimization analysis was performed to compare the costs of DCB and DES.
    We present 1952 all-comer, consecutive patients; 902 (1064 lesions) treated with DCB and 1050 (1236 lesions) treated with DES for de novo coronary artery disease. The cost per patient was estimated to be £9.02 more expensive in the DCB group (£3153.00 vs. £3143.98). However, the cost per lesion treated was calculated to be £15.51 cheaper in the DCB group (£3007.56 vs. £3023.07). The results were consistent irrespective of duration of long-term antiplatelet medications.
    We have compared the cost-effectiveness of DCB-only angioplasty to DES-angioplasty and showed that the per patient and per lesion results were not different and hence cost should not be implicated in the decision to choose DCB or DES.
