概括
使用超老年捐赠者 (≥65岁) 的心脏移植显示3年生存率较低,但可比的次要结果相似. 这表明,来自老年捐赠者的心脏可能适合移植,特别是在老年接受者身上.
科学领域:
- 心脏病学 心脏病学
- 移植手术 移植手术
- 老年医学 老年医学
背景情况:
- 心脏移植 (HTx) 是对末期心力衰竭的关键治疗方法.
- 来自老年捐献者或超老年捐献者 (SAD) 的器官使用正在增加,以解决器官短缺问题.
- 使用SAD评估HTx的结果和全移植功能对于优化患者护理至关重要.
研究的目的:
- 评估从超年龄捐赠者 (SAD,≥65岁) 接受心脏移植的心脏移植患者的临床结果和连续异种移植功能.
- 将这些结果与从年轻的捐赠者 (YD, <65岁) 接受心脏的接受者进行比较.
主要方法:
- 在1999年至2022年期间,对成年HTx接受者的回顾性审查.
- 患者被分为两个组:SAD (捐赠者年龄≥65岁,n=12) 和YD (捐赠者年龄<65岁,n=140).
- 主要终点是3年全因死亡率;次要终点包括死亡,心力衰竭住院,拒绝和干预. 序列心脏功能通过心声回声和右心脏导管检查来评估.
主要成果:
- 与YD受体相比,SAD受体年龄较大,心脏功能受损 (更高的E / e,更低的心脏指数) 在移植后一个月.
- 移植后一年,SAD接受者保持了相似的心脏指数,但具有更高的E/e'值.
- 与YD组 (97.8%) 相比,SAD组的3年整体存活率明显低 (81.5%).
- 二级终点,包括死亡,心力衰竭住院和拒绝率,在两组之间是可比的.
结论:
- 使用来自超年龄 (≥65岁) 捐献者的器官进行心脏移植是可行的,并且可以产生可接受的结果.
- 在中期内,整体移植功能似乎充足,即使移植后初始心脏功能受损.
- 虽然3年生存率降低,但SAD心脏可能是一个可行的选择,特别是对于年长的接受者,有助于减轻捐赠器官短缺.
