概括
慢性通皮冠状动脉干预 (CTO-PCI) 可以激活血小板并影响microRNA水平. 虽然这些程序可能会导致暂时的血小板激活和内皮功能障碍,但它们与增加的不良临床事件无关.
科学领域:
- 心血管医学 心血管医学
- 干预心脏病学 干预心脏病学
- 生物标志物 生物标志物
背景情况:
- 穿皮冠状动脉干预 (PCI) 是慢性全闭症 (CTO) 的关键治疗方法.
- CTO-PCI程序是复杂的,可以引起压力,可能导致血小板激活.
- 循环中的microRNAs (miRs) 与血小板和内皮功能有关.
研究的目的:
- 评估CTO-PCI对血小板激活的影响.
- 在CTO-PCI后评估miR-223,miR-181b和miR-126的血水平的变化.
- 为了将程序特征与这些生物标志物和临床结果相关联.
主要方法:
- 对50名接受CTO-PCI的患者进行前性研究.
- 血液样本采集在PCI前,PCI后2天,PCI后3-6个月.
- 评估了血小板激活标记物 (P-选择素,可溶性P-选择素) 和血miR水平.
主要成果:
- 较高的日本CTO分数和较长的PCI持续时间与高的P-选择素水平相关.
- 较长的PCI持续时间和较高的CTO分数与3-6个月的可溶性P-选择素增加有关.
- 较短的支架总长度与3-6个月的miR-181b表达减少有关;miR-223和miR-126没有显著变化.

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Formation of the Platelet Plug
6.5K
The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
