Stunned myocardium can occur after abdominal surgery, potentially triggered by perioperative hemodynamic changes and shivering, requiring careful monitoring to prevent irreversible ischemia.

Stunned myocardium may occur after abdominal surgery; hypothesis-generating for perioperative BP fluctuations and shivering as triggers, needing prospective study.
術後stunned myocardiumが疑われた開腹術3症例を経験した.3症例とも60代女性で,それぞれ直腸切断術,回盲部切除術,および結腸切除術と肝部分切除術が行なわれた.主に血行動態,心電図および心エコー図の経時的変化より本病態が疑われた.誘因として術中の血圧変動,麻酔覚醒時のシバリングが考えられた.原因は1例で冠スパスムが考えられたが,他の2例では不明であった.Stunned myocardiumは基本的には可逆性の病態であるが,治療の良否によっては不可逆的な心筋虚血に進行するかもしれない.周術期心筋梗塞との関連性は不明であり今後さらなる検討が必要であろう.
