急性心肌梗死后T波倒置是降低30天病死率的标志

Negative T wave after acute myocardial infarction is the sign of decreasing 30-day death rates

目的探讨急性心肌梗死后有无 T波倒置患者 30天病死率的差异。方法回顾分析 1997年 1月～ 2 0 0 0年 12月收治的至少存活2 4小时以上的 2 36例急性心肌梗死患者的临床资料 ,将其分成 T波倒置组及无 T波倒置组。结果 T波倒置患者 15 8例 ( 6 6 .9% ) ,无 T波倒置患者 78例 ( 33.1% )。 30天后 T波倒置组 6例死亡 ( 3.8% ) ,而无 T波倒置组 10例死亡 ( 12 .8% ) ,两组病死率比较有显著性差异 ( P<0 .0 1)。结论急性心肌梗死后出现 T波倒置是降低

Objective To explore the differences of 30-day death rate in patients with acute myocardial infarction(AMI) between the patients with and without negative T wave.Methods 236 AMI cases who were alive beyond 24 hours were divided into the groups with negative T waves and without negative T wave from January 1997 to December 2000. The data were analyzed retrospectively .Results negative T wave was found in 158 cases (67%) and was not found in 78 cases (33%).30 days later, 6 patients(3.8%) with negative T wave died and 10 patients (12.8%) without negative T wave died. The death rates were dramatically different (P<0.01).Conclusion Negative T wave after AMI is the sign of decreasing 30-day death rates.
