Objectives ⑶ Evaluation of myocardial infarction in patients with changes in the characteristics of myocardial tissue trends and prognosis and early reperfusion on myocardial tissue density ⒚ method ⑶ we analyzed the first incidence of 69 cases of Q wave acute myocardial infarction within 24 hours after admission, 72 hours, 2 weeks, 3 months and 6 months of myocardial graying ⒚ according to whether the patients with early reperfusion were divided into ⑶ 46 cases without early reperfusion group ⒙ 16 cases of early reperfusion group and 7 cases of death group ⒚ results ⑶ In the early reperfusion group, myocardial infarction area of myocardial gray-scale mean value, dispersion in 3 months after admission was significantly higher than admission ⒉ P <0 0 5 ⒕⒚ early reperfusion group myocardial infarction area mean gray value, dispersion 2 weeks after admission began to decline ⒉ P <0 05 ⒕⒚ death group myocardial infarction area of myocardial gray-scale value increased significantly after 72 hours of admission ⒉ P <0 5 ⒕⒚ ⒕⒚ Conclusion ⑶ determined by ultrasound tissue video method to determine myocardial The gray scale index reflects the dynamic changes in myocardial tissue structure during myocardial remodeling after myocardial infarction Period of reperfusion allows infarction area tissue density and non-infarction zone ventricular remodeling reduced ⒚
