目的：探究急性心肌梗死患者冠脉内血栓类型与心电图ST段改变的相关关系。方法：对65例ST段抬高型心肌梗死（STEMI）患者和42例非ST段抬高型心肌梗死（NSTEMI）患者于急诊冠脉介入治疗时行血栓抽吸，分析2组抽吸血栓的组织病理学结果。结果：STEMI组抽吸血栓48例，其中红色／混合血栓39例（81．3％），白色血栓9例（18．7％）；NSTEMI组抽吸血栓12例，其中白色血栓8例（66．7％），红色／混合血栓4例（33．3％）。结论：红色／混合血栓和白色血栓均可见于ST段抬高型和非ST段抬高型心肌梗死，提示包括血栓形成在内的多种因素共同作用导致了急性心肌梗死时心电图ST段的改变。

Objective To investigate the relationship between pathological types of intracoronary thrombus and changes of ST segment in patients with acute myocardial infarction. Methods Thrombus aspiration during primary PCI was performed in 65 ST-elevation myocardial infarction (STEMI) patients and 42 non-ST-elevation myocardial infarction (NSTEMI) patients. Pathological analysis on thrombosis was made. Results Thrombi characteristics were collected from 48 STEMI patients and 12 NSTEMI patients. In the STEMI group, 39(81.3%) red/mixed thrombus and 9(18.7%) white thrombus were found. While in the NSTEMI group, 8(66.7%) white thrombus and 4(33.3%) red/mixed thrombus were obtained. Conclusions There are both red/mixed and white thrombus in the two kinds of acute myocardial infarction. A variety of elements, including thrombus formation, could contributes to the change of ST in electrocardiograph during acute myocardial infarction.
