国内外一些报道对墓碑状ST段抬高的急性心肌梗死（AMI）患者的观察，在选择病例进行组间比较时有个共同点，即对照组病例数远远高于观察组［’－’］。我们采用与上述作者不同的方法，在AMI死亡组与对照组例数相同的情况下进行组间比较，重新认识墓碑状ST段抬高对AMI预后的影响。
Some reports at home and abroad on tombstone-like ST-elevation acute myocardial infarction (AMI) observed in the selection of patients for comparison between groups have one thing in common, that is, the number of cases in the control group is much higher than the observation group [’- ]. We used a different approach from the authors above to compare the impact of ST-segment elevation on tombstoning with AMI on the basis of the same number of AMI death and control groups.
