In emergency CABG for ACS, on-pump beating-heart CABG is a viable option for hemodynamically unstable patients, with postoperative morbidity primarily driven by preoperative severity rather than the surgical technique itself.
急性冠症候群に対する緊急CABGの手術成績は待機例に比しいまだ不良である.今回,2004年から2008年までの単独CABG 432例中,緊急/準緊急手術を必要とした72例を対象とし,これらの症例をon pump beating CABG群とOPCABの2群に分け検討した.On群では,AMI症例,トロポニンT陽性例,術前CK値,低心機能例,術前MR2度以上,心拡大例はいずれも高値であった.術中因子に両群間の有意差を認めなかった.術後因子では,在院死亡をon群3.2%,off群7.3%に認めた.術後合併症はon群に有意に高値であり,特に呼吸不全,ICU滞在日数,低心拍出量症候群はon群に高値であり術後管理に難渋した症例が多かった.ロジスティック回帰分析では,術前CK値が有意な合併症の危険因子であった.
