概括
左心房尾关闭 (LAAC) 是一个安全和可行的选择,为心房的患者拒绝口服抗凝剂 (OAC). 这种程序表明,与预测的风险相比,在三年内有望减少缺血性结局.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 医疗器械 医疗器械
背景情况:
- 左心房尾关闭 (LAAC) 是心房动 (AF) 患者的替代方案,这些患者不能容忍口服抗凝剂 (OAC).
- 在拒绝OAC的患者中,LAAC的疗效和安全性在很大程度上仍未确定.
研究的目的:
- 在拒绝OAC的AF患者中评估LAAC的疗效和安全性.
- 为了比较OAC拒绝患者接受LAAC的结果与那些接受LAAC的已确定的适应症患者.
主要方法:
- 一个连续AF患者进行皮肤穿LAAC (2009-2022) 的多中心追溯分析.
- 患者被分为OAC拒绝组和对照组 (标准指示的LAAC).
- 主要终点:心血管死亡,中风或全身栓塞的组合;次要终点:技术成功和程序并发症.
主要成果:
- 119名患者 (4.5%) 由于OAC拒绝而接受LAAC;确定了238名对照.
- OAC拒绝组包括年轻的,风险较低的患者.
- 在3年后,拒绝组的主要终点显着较低 (4.2%对17.2%;aHR:0.37;P=0.048).
- 技术成功率和并发症率在各组之间是相似的.
- 在拒绝组中,血栓栓塞事件 (2.3%) 和大出血 (1.9%) 的年率与预测得分相比显著降低了风险.
结论:
- OAC拒绝是LAAC的罕见迹象,但代表了一个可行的和安全的程序选项.
- 在OAC拒绝患者中,LAAC在3年内显示出有希望的缺血性结局率.
- 需要进一步的研究来阐明LAAC与OAC在这个特定的患者亚组中的比较益处.

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...

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
