With the development of modern science and technology, ultrasound biomicroscopy has been widely used in biological research. With the increasing number of patients with acute myocardial infarction, it is very important to observe and analyze the coronary blood flow of acute myocardial infarction. The purpose of this study was to evaluate the coronary blood flow in exercise-induced acute myocardial infarction (AMI) by using a biomicroscope. The method used in this study is to construct three different coronary artery bypass grafting models. The solid thrombus samples in the dehydration tank were put into the aspirate, and the precipitate was separated by centrifugation. Soak in 10% neutral formalin solution for 4 hours and send to the Department of pathology within 24 hours. The thrombus was dehydrated with xylene and embedded in paraffin block. Along the central horizontal section, there were at least 5 consecutive sections of each specimen with a thickness of 5 μ M. after he staining, the specimens were observed under a microscope. The results showed that the proportion of white thrombus in less than 4 hours was significantly higher than that in 4 to 7 hours and more than 7 hours (61.2% vs. 19.4%, 19.4%, P < 0.01), and the proportion of mixed thrombus in 4 to 7 hours was significantly higher than that in less than 4 hours and more than 7 hours (52.6% vs. 29.0%, 18.4%, P < 0.05). It can be concluded that there is no significant statistical difference in the effect of different types of thrombus on acute myocardial infarction, but the white thrombosis group has a certain improvement trend. This study provides a reliable method for the diagnosis of biological heart diseases.
