《急诊每日一题》心脏移植后肌钙蛋白或脑钠肽升高意义2021年11月
Question 问题:
A patient who has had a recent cardiac transplant presents to the ED. Both troponin and BNP are elevated. Is this concerning? If so, why?
一个最近心脏移植患者到急诊科就诊。肌钙蛋白和脑钠肽都有升高。会有什么顾虑?如有,为什么?
Answer 答案:
Troponin is elevated for up to 3 months after surgery but then should normalize. BNP elevations peak within the first 2 months, then returns to normal. Troponin and BNP elevation after these periods can suggest graft rejection.
手术后到3个月内肌钙蛋白会有升高,然后会恢复正常。脑钠肽会在2个月达高峰,然后恢复正常。这段时间后肌钙蛋白和脑钠肽升高可能提示移植排斥。
