摘要
目的 :探讨血清心肌肌钙蛋白 T(c Tn T)和心肌酶谱在心肌损伤前后含量的变化与其临床意义。方法 :动态观察 2 0例二尖瓣瓣膜置换术 (MVR)患者手术前、手术后 2 h及 2 4h血清 c Tn T和心肌酶谱变化。另制备家兔心肌损伤模型 ,检测动物模型伤前和伤后 4,8,2 4h血清 c Tn T的变化特点。结果 :二尖瓣瓣膜置换术患者血清 c Tn T含量、心肌酶谱活性在术后 2 ,2 4h较术前显著升高 (P<0 .0 1) ,其中血清 c Tn T含量术后 2 h增加倍数高于其他指标。家兔心肌损伤模型伤后 4,8,2 4h血清 c Tn T含量较伤前升高非常显著 (P<0 .0 1)。结果 ;血清 c Tn T含量及心肌酶谱活性均对心肌损伤的诊断有意义 ,c Tn T的心肌特异性及早期灵敏度更高
