Abstract

OBJECTIVES:This study sought to define contemporary rates of drug eluting stent (DES) usage in patients with chronic kidney disease (CKD).,BACKGROUND:Among patients with CKD undergoing percutaneous coronary interventions (PCIs), outcomes are superior for those who receive DES compared to those who receive bare metal stents (BMSs). However, perceived barriers may limit the use of DES in this population.,METHODS:All adult PCI cases from the NCDR CathPCI Registry involving coronary stent placement between July 1, 2009 and December 31, 2015 were analyzed. The rate of DES usage was then compared among four groups, stratified by CKD stage (I/II, III, IV, and V). Subgroup analysis was conducted based on PCI status and indication. Cases were linked to Medicare claims data to assess 1-year mortality.,RESULTS:A total of 3,650,333 PCI cases met criteria for analysis. DES usage significantly declined as renal function worsened (83.0%, 79.9%, 75.6%, and 75.6%, respectively, in the four CKD stages; p < .001). DES usage was universally lower across the four groups in the setting of ST-Elevation Myocardial Infarction (STEMI) (70.6%, 66.5%, 58.7%, 58.0%; p < .001) and higher in the setting of elective PCI (87.6%, 84.9%, 82.3%, 77.9%; p < .0001). DES was associated with improved 1-year survival, and usage increased over time across each group.,CONCLUSIONS:DESs are underutilized in patients with advanced renal dysfunction. Although DES usage has increased over time, variation still exists between patients with normal renal function and those with CKD.

摘要

目的: 本研究旨在确定慢性肾脏病 (CKD) 患者药物洗脱支架 (DES) 使用率。背景: 在接受经皮冠状动脉介入治疗 (PCIs) 的 CKD 患者中,接受 DES 的患者预后优于接受裸金属支架 (BMSs) 的患者。然而,感知障碍可能限制 DES 在该人群中的使用。方法: 分析 2009年7月1日至 2015年12月31日期间 NCDR CathPCI 登记研究中涉及冠状动脉支架置入的所有成人 PCI 病例。然后比较四组中 DES 使用率,按 CKD 分期 (I/II 、 III 、 IV 和 V) 分层。根据 PCI 状态和适应症进行亚组分析。病例与医疗保险索赔数据相关,以评估 1 年死亡率。结果: 共有 3,650,333 例 PCI 病例符合分析标准。随着肾功能恶化,DES 使用率显著下降 (4 个 CKD 分期分别为 83.0% 、 79.9% 、 75.6% 和 75.6%; P <.001)。在 ST 段抬高型心肌梗死 (STEMI) 的情况下,四组的 DES 使用率普遍较低 (70.6%,66.5%,58.7%,58.0%; P <.001) 在择期 PCI 的情况下更高 (87.6%,84.9%,82.3%,77.9%; P <.0001)。DES 与改善的 1 年生存率相关,并且随着时间的推移,各组的使用量都在增加。结论: DESs 在晚期肾功能不全患者中未被充分利用。尽管随着时间的推移,DES 的使用有所增加,但肾功能正常的患者和 CKD 患者之间仍然存在变异。

METHODS:Aims : We sought to investigate the thrombogenicity of different DES and BMS in an in vitro system of stent perfusion. Material and Methods: The experimental model consisted of a peristaltic pump connected to 4 parallel silicone tubes in which different stents were deployed. Blood was drawn from healthy volunteers and the amount of stent surfaced -induced thrombus deposition was determined using 125 I -fibrinogen. Results: Compared to Resolute, Biomatrix and Vision, Xience was associated with the lowest amount of stent surface -induced thrombus formation, with a significant difference compared to Vision (125 I -fibrinogen median value deposition [IQ range]: 50 ng [25 -98] versus 560 ng [320 - 1,520], respectively, p<0.05), but not to other DES. In the second set of experiments Fluoropolymer -coated BMS not eluting drug was associated with a significant 3 -fold reduction in 125 I -fibrinogen deposition (245 ng [80 -300]) compared to Vision (625 ng [320 -760], p<0.05), but a 7 -fold increase compared to Xience (35 ng [20 -60], p<0.05). Finally Xience was associated with a significantly greater absorption of albumin compared to BMS. Conclusions: In an in vitro system of stent perfusion, Xience was associated with the lowest amount of stent surface -induced thrombus formation compared with Resolute, Biomatrix and Vision, with a noted synergistic effect between the fluoropolymer and the drug.

METHODS::Fibronectin-splice variant containing extra domain A (Fn-EDA) is associated with smooth muscle cells (SMCs) following vascular injury. The role of SMC-derived Fn-EDA in SMC phenotypic switching or its implication in neointimal hyperplasia remains unclear. Herein, using human coronary artery sections with a bare metal stent, we demonstrate the expression of Fn-EDA in the vicinity of SMC-rich neointima and peri-strut areas. In mice, Fn-EDA colocalizes with SMCs in the neointima of injured carotid arteries and promotes neointima formation in the comorbid condition of hyperlipidemia by potentiating SMC proliferation and migration. No sex-based differences were observed. Mechanistic studies suggested that Fn-EDA mediates integrin- and TLR4-dependent proliferation and migration through activation of FAK/Src and Akt1/mTOR signaling, respectively. Specific deletion of Fn-EDA in SMCs, but not in endothelial cells, reduced intimal hyperplasia and suppressed the SMC synthetic phenotype concomitant with decreased Akt1/mTOR signaling. Targeting Fn-EDA in human aortic SMCs suppressed the synthetic phenotype and downregulated Akt1/mTOR signaling. These results reveal that SMC-derived Fn-EDA potentiates phenotypic switching in human and mouse aortic SMCs and neointimal hyperplasia in the mouse. We suggest that targeting Fn-EDA could be explored as a potential therapeutic strategy to reduce neointimal hyperplasia.

METHODS:OBJECTIVE:The goal of this study was to determine the impact of late-acquired stent malapposition (LASM) on long-term clinical outcomes in patients treated with coronary stent implantation. Approach and Results: We investigated major adverse cardiac event during 10 years after 6-month intravascular ultrasound examination using our previous studies database. A total of 732 patients treated with bare-metal stent (54 LASM versus 678 non-LASM) and 529 patients treated with first-generation drug-eluting stent (82 LASM versus 447 non-LASM), who did not have clinical event or censoring at the time of follow-up intravascular ultrasound, were included for the present analysis. major adverse cardiac event was defined as the composite of cardiac death, target vessel-related myocardial infarction, target lesion revascularization and stent thrombosis. Multivariable adjustment and inverse probability weight were performed to consider baseline differences. After multivariable adjustment, LASM was related to a greater risk of major adverse cardiac event (hazard ratio, 1.666 [95% CI, 1.041-2.665]; P=0.0333) and very-late stent thrombosis (hazard ratio, 3.529 [95% CI, 1.153-10.798]; P=0.0271) than non-LASM in patients treated with first-generation drug-eluting stent, but not in those treated with bare-metal stent. Results were consistent after inverse probability weight. Among patients with LASM of first-generation drug-eluting stent, no late stent thrombosis occurred in patients who continued to receive dual antiplatelet therapy. CONCLUSIONS:The relationship between LASM and major adverse cardiac event might depend on the type of implanted stents during the long-term follow-up, highlighting the clinical significance of polymers and drugs in drug-eluting stent system.
