Abstract: 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.
