Abstract

BACKGROUND:Many studies have reported the predictive value of the atherogenic index of plasma (AIP) in the progression of atherosclerosis and the prognosis of percutaneous coronary intervention (PCI). However, the utility of the AIP for prediction is unknown after PCI among type 2 diabetes mellitus (T2DM). METHODS:2356 patients with T2DM who underwent PCI were enrolled and followed up for 4 years. The primary outcome was major cardiovascular and cerebrovascular adverse events (MACCEs), considered to be a combination of cardiogenic death, myocardial infarction, repeated revascularization, and stroke. Secondary endpoints included all-cause mortality, target vessel revascularization (TVR), and non-target vessel revascularization (non-TVR). Multivariate Cox proportional hazards regression modelling found that the AIP was correlated with prognosis and verified by multiple models. According to the optimal cut-off point of the ROC curve, the population was divided into high/low-AIP groups. A total of 821 pairs were successfully matched using propensity score matching. Then, survival analysis was performed on both groups. RESULTS:The overall incidence of MACCEs was 20.50% during a median of 47.50 months of follow-up. The multivariate Cox proportional hazards regression analysis before matching suggested that the AIP was an independent risk factor for the prognosis of T2DM after PCI (hazard ratio [HR] 1.528, 95% CI 1.100-2.123, P = 0.011). According to the survival analysis of the matched population, the prognosis of the high AIP group was significantly worse than that of the low AIP group (HR (95% CI) 1.614 (1.303-2.001), P < 0.001), and the difference was mainly caused by repeat revascularization. The low-density lipoprotein-cholesterol (LDL-C) level did not affect the prognosis of patients with T2DM (P = 0.169), and the effect of the AIP on prognosis was also not affected by LDL-C level (P < 0.001). CONCLUSIONS:The AIP, a comprehensive index of lipid management in patients with T2DM, affects prognosis after PCI. The prognosis of diabetic patients with high levels of the AIP included more MACCEs and was not affected by LDL-C levels. It is recommended to monitor the AIP for lipid management in diabetic patients after PCI and ensure that the AIP is not higher than 0.318. Trial registration This is an observational cohort study that does not involve interventions. So we didn't register. We guarantee that the research is authentic and reliable, and hope that your journal can give us a chance.

摘要

背景: 许多研究报道了血浆致动脉粥样硬化指数 (AIP) 对动脉粥样硬化进展和经皮冠状动脉介入治疗 (PCI) 预后的预测价值。然而,AIP 在 2 型糖尿病 (T2DM) PCI 术后预测中的效用尚不清楚。 方法: 入选 2356 例行 PCI 的 T2DM 患者,随访 4 年。主要结局为主要心脑血管不良事件 (MACCEs),被认为是心源性死亡、心肌梗死、反复血运重建和卒中的组合。次要终点包括全因死亡率、靶血管血运重建 (TVR) 和非靶血管血运重建 (non-TVR)。多变量 Cox 比例风险回归模型发现 AIP 与预后相关,并经多模型验证。根据 ROC 曲线的最佳截点,将人群分为高/低 AIP 组。使用倾向评分匹配成功匹配的共 821 对。然后,对两组进行生存分析。 结果: 中位随访时间为 20.50% 个月,MACCEs 的总发生率为 47.50。匹配前多因素 Cox 比例风险回归分析提示 AIP 是 PCI 术后 T2DM 预后的独立危险因素 (风险比 [HR] 1.528,95% CI 1.100-2.123, p = 0.011)。根据匹配人群生存分析,高 AIP 组预后明显差于低 AIP 组 (HR (95% CI) 1.614 (1.303-2.001), p

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.
