概括
比瓦利鲁丁是一种安全的替代未分离氨酸 (UFH),用于儿童HeartMate 3患者的早期抗凝药. 这两种药物都显示出类似的中风和出血率,支持在机械循环支持中使用比瓦利鲁丁.
科学领域:
- 心脏病学 心脏病学
- 生物医学工程 生物医学工程
- 儿科重症监护 儿科重症监护
背景情况:
- 比瓦利鲁丁越来越多地用于儿科机械循环支 (MCS),并显示了对体外脉动装置的改善结果.
- 实践变化存在于儿童患者的早期抗凝治疗中,这些患者植入了诸如HeartMate 3之类的连续流装置.
- 了解早期的血液相容性事件对于优化这种人群中的抗凝策略至关重要.
研究的目的:
- 为了比较儿童HeartMate 3患者在14天内发生的早期血红相容性相关不良事件,这些患者接受了比瓦利鲁丁与未分离的肝素 (UFH).
- 为了评估比瓦利鲁丁作为初始抗凝剂的安全性和有效性,与UFH相比,在使用HeartMate 3设备的儿科患者中.
主要方法:
- 用ACTION VAD注册表数据对234名植入HeartMate 3的儿科患者 (25岁以下) 进行了回顾性分析.
- 患者被分为两组:初始抗凝药用比瓦利鲁丁 (n=100) 或UFH (n=134).
- 评估了包括无中风,出血和过渡到口服抗凝药的时间在内的结果,在药剂变化时审查了数据.
主要成果:
- 在非中风 (96.9% vs. 96.3%,p=0.77) 或出血 (94.8% vs. 89.9%,p=0.21) 之间,在比瓦利鲁丁和UFH组之间没有发现显著差异.
- 与UFH组相比,接受比瓦利鲁丁的患者过渡到口服抗凝药的时间较长.
- 两组抗凝血剂之间的一年生存率相似.
结论:
- 比瓦利鲁丁是UFH的可行的替代品,用于儿童患者早期的血栓预防,其中包括HeartMate 3植入器.
- 相似的中风和出血率表明,在这个特定的患者群体中,这两种药物的安全性概况相似.
- 进一步的研究可能会探索在接受比瓦利鲁丁治疗的患者中优化过渡到口服抗凝药的策略.
