概括
中性粒细胞外细胞陷 (NETs) 与外周动脉疾病 (PAD) 的严重程度和不良结果有关. 较高的NETs标志物与复原,纤维素凝块特性变化以及治疗后重新干预,截肢或死亡的风险增加有关.
科学领域:
- 心血管医学 心血管医学
- 血液学 血液学 血液学
- 免疫学 免疫学 免疫学
背景情况:
- 中性粒细胞外细胞陷 (NETs) 涉及到动脉血症.
- NETs在外周动脉疾病 (PAD) 严重程度和治疗后的结果中的作用尚不清楚.
研究的目的:
- 调查在接受内血管治疗的患者中,NETs相关标志物与PAD严重程度之间的关联.
- 为了确定NETs标志物是否预测PAD的内血管治疗后的长期结果,包括复原症.
- 探索NETs对纤维素凝块性质和血栓生成的影响.
主要方法:
- 该研究包括85名患有慢性四肢威胁性缺血症 (CLTI) 和内血管治疗后复原症的患者,以及47名PAD对照.
- 评估了NETs标记物 (H3cit,MPO,PAD4,cfDNA),纤维素凝块透性 (Ks),凝块溶解时间 (CLT),血栓生成和纤维素分解标记物.
- 随访评估了复杂的重复干预,截肢和死亡的综合终点.
主要成果:
- 与对照组相比,患有CLTI和静脉缩的患者表现出H3cit,MPO和cfDNA的水平升高.
- 鲁瑟福类与在复原和对照组中的NETs标志物相关.
- 较高的NETs标志物 (H3cit,cfDNA) 与复原组中纤维素凝块透率 (Ks) 降低和凝块溶解时间 (CLT) 延长有关.
- 在随访期间死亡的患者中观察到H3cit,MPO和cfDNA度升高.
- 多变量分析确定了H3cit,ETP,α2-抗等离子素和Ks作为不良结果的独立预测因素.
结论:
- 升高的NETs相关标记物和前血栓性纤维素凝块性质是内血管治疗PAD患者的特征,这些患者有1年复原症的高风险.
- 较高的NET标志物水平与PAD患者在内血管治疗后的长期结果较差有关.

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
