摘要 目的 探讨胸痛发作时心电图 (ECG)改变对不稳定性心绞痛 (UA)危险分层的临床价值。方法 分析了 2 46例UA患者胸痛发作时标准 12导联ECG的变化 ,观察了ST段压低、ST段抬高、T波倒置和无ST T改变 4组患者住院期间心脏性死亡和急性心肌梗死 (AMI)的发生率 ,分析了ST段压低对UA短期预后的影响。结果 胸痛发作时ECG有ST段压低 81例(32 9% )、ST段抬高 2 0例 (8 1% )、T波倒置 2 8例 (11 4% ) ,无ST T改变 117例 (4 7 6 % )。ST段压低组AMI和心脏性死亡的发生率为 19 8% ,显著高于ST段抬高组 (5 0 % )、T波倒置组 (7 1% )和无ST T改变组 (1 7% ) (P <0 0 1) ,后 3组之间无显著性差异。ST段压低对住院期间发生心脏事件 (包括AMI、心脏性死亡和难治性心绞痛 )的阳性预测值为 2 3 5 % ,阴性预测值为92 7%。校正年龄、性别、心绞痛分级等因素后 ,胸痛发作时ST段压低仍是UA患者住院期间发生AMI和心脏性死亡独立危险因素 ,其相对危险度约为 8 0 (P =0 0 0 12 )。结论 胸痛发作时ST段压低是UA患者近期内发生AMI和心脏性死亡的独立危险因素 。
