概括
对于带有左心室辅助器件的患者来说,无论临床医生是否与抗凝药搭建桥梁,次治疗国际规范化比率 (INR) 水平都不会导致更糟糕的结果. 这一发现表明,对于当前几代设备来说,管理方面的转变是必要的.
科学领域:
- 心脏病学 心脏病学
- 生物医学工程 生物医学工程
背景情况:
- 左心室辅助装置 (LVAD) 已经得到改善,但对血栓栓塞并发症的担忧在历史上需要进行常规的腹腔抗凝剂桥梁,以治疗次国际规范化比率 (INR).
- 目前的LVAD技术可能会改变与次治疗INR相关的风险,促使对管理策略进行审查.
研究的目的:
- 分析当前一代LVAD患者的亚治疗性INR事件的管理策略.
- 为了比较 LVAD 患者的亚治疗性 INR 事件的桥梁和非桥梁策略之间的结果.
主要方法:
- 来自MOMENTUM 3试验的数据分析,重点关注美国中部地区的6个中心.
- 对225名LVAD患者的图表综述,这些患者在入院后经历了次治疗INR (<2) 事件.
- 管理策略的分类:桥接 (皮下或静脉注射药物) 或非桥接 (华法林剂量调整或不改变).
主要成果:
- 在225名患者中,130人 (58%) 经历了235次治疗INR事件.
- 大多数事件 (76.2%) 没有桥梁;100涉及华法林剂量调整,79没有变化.
- 在56个桥接事件中,53.6%使用了皮下药物,46.4%使用了静脉注射药物.
- 桥接组和非桥接组之间没有观察到个人结局或复合终点 (死亡,再住院,CVA,出血) 的显著差异.
结论:
- 当前一代LVADs患者的亚治疗INR事件与桥接或不桥接管理显示了类似的临床结果.
- 这些发现表明,对于当代LVAD来说,可能不需要对次治疗INR进行例行桥梁.
- 在LVAD患者中治疗次级INR的管理策略可能正在发展.

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...
