概括
导管血栓溶解 (CDT) 加上抗凝药在中等风险肺栓塞 (PE) 患者中迅速改善了右心室功能. 这种治疗的安全性与单独的抗凝药药物相提并论,因此需要在更大的研究中进一步调查.
科学领域:
- 心脏病学 心脏病学
- 干预性放射学 干预性放射学
- 肺部医学 肺部医学
背景情况:
- 中级风险肺栓塞 (PE) 具有右心室 (RV) 功能障碍而没有血液动力学不稳定性的特征,造成显著的不良后果风险.
- 抗凝药是标准的治疗方法,但对于PE中RV功能障碍的最佳策略仍在争论中.
- 导管血栓溶解 (CDT) 是系统血栓溶解的潜在替代品,其短期疗效和安全性需要进一步定义.
研究的目的:
- 为了比较CDT加抗凝剂与单独抗凝剂在急性中期风险PE患者改善VR功能方面的短期疗效.
- 评估和比较两种治疗策略的安全性,包括出血事件.
- 在这个患者队列中确定VR功能改善的预后因素.
主要方法:
- 在2020年3月至2023年2月期间,对89名急性中期风险PE患者进行了回顾性分析.
- 患者被分为两组:33组接受CDT加抗凝药,56组仅接受抗凝药.
- 主要结局:与基线相比,1周后的RV/左心室 (LV) 比率的差异. 安全结果包括重大出血和临床相关的非重大出血 (CRNMB).
主要成果:
- 与抗凝血剂组相比,CDT组在RV/LV比率上表现出显著更大的改善 (34.0%对19.4%,P<0.001).
- 在CDT组中观察到更高的Qanadli得分改善率 (65.0%对52.5%,P=0.03).
- CDT是VR/LV比率改善的独立有利预后因素 (P=0.02). 在CDT组中发生了一名患者 (3.0%) 的严重出血;在组之间没有发现CRNMB的显著差异.
结论:
- 结合抗凝药的CDT似乎有助于在中等风险PE患者的VR功能的快速短期改善.
- 在这个队列中,CDT加抗凝固剂和单独抗凝固剂的安全性,特别是出血风险是可比的.
- 需要进行更大规模的前性研究,以确定CDT在这种环境中的安全性和有效性.

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...

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...

601
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
