墓碑样ST段抬高的急性心肌梗死的再分析

目的探讨急性心肌梗死（AMI）墓碑形”段抬高的临床意义。方法根据临床资料将28例心电图呈“墓碑样”改变的AMI患者作为观察组（A组），选取心电图ST段呈常态改变的AMI患者43例作为对照组（B组）。将两组患者的临床资料进行分析并作统计学处理。结果病变多发于前降支，除天门冬氨酸转氨酶（AST）、乳酸脱氢酶（LDH）外，心源性休克、AMI后心绞痛、严重心律失常、心力衰竭、≥3个并发症及病死率、肌酸激酶（CK）、肌酸激酶同功酶（CK—MB）A组与B组相比，差异有统计学意义（P〈0．01）。结论ST段呈墓碑样改变的AMI患者近期预后较凶险。

Analyzing of tombstone-like elevation of ST segment in acute myocardial infarction

Objective The aim of study was to explore the clinical manifestation of tombstone-like elevation of ST segment in acute myocardial infarction. Methods 28 patients with tombstone-like elevation of ST segment in AMI were enrolled as group A and 43 patients were randomly selected with common changes of ST segment in AMI as control group （group B）.The clinical data of the two groups were analyzed and compared. Results The main lesion of coronary artery was left anterior descending branch （LAD） in group A.Except for lactic dehydrogenase（LDH ） and aspartate transaminase（AST）, there were significant difference between group A and group B in heart failure, cardiogenic shock, fatal cardiac arrhythmia, postinfarction angina pectoris, more than three heart complications, mortality, creatine kinase （CK） and ereatine kinase-MB （CK-MB） （P〈0.01） Conclusion The prognosis of patients with the tombstone-like elevation of ST segment in AMI is very dangerous within a short time.
