摘要：Objectives The purpose of this study was to determine if the ultrasonic integrated backscatter and echo intensity could be used in clinical diagnosis of acute myocardial infarction. Methods and Results Within 2 weeks after acute myocardial infarction, 35 patients underwent ultrasonic tissue characterization from the papillary short- axis view.The cyclic variation of integrated backscatter and echo intensity of three different myocardial regions perfused by left anterior descending coronary artery, left cir cumflex coronary and right coronary were measured .The value of cyclic variation of integrated backscatter and integrated backscatter and echo intensity ≤ half of the highest value of three different myocardial regions on a same view were define as the criteria for diag nosing acute myocardial infarction , and the results were compared with coronary angiography. The sensitivity of diagnosing acute myocardial infarction by both Ultrasonic tissue characterization with integrated backscatter and echo intensity were 91.43 % . The location of myocardial infarction detected by this technique corresponded with the damaged myocardial region determined by coronary angiography. Conclusions Ultrasonic tissue characterization with integrated backscatter and echo intensity could clinically be used as a noninvasive approach in the diagnosis of acute myocardial infarction.
