应用二维斑点追踪显像技术评价犬缺血心肌左心房功能的变化
Application of Speckle Tracking Imaging Technology in Evaluation of Left Atrial Function Changes in Canine Stunned Myocardium
摘要
Abstract
Objective To evaluate the function changes of left atrial in canine stunned myocardium model both before and after acute my-ocardial infarction by using two-dimensional speckle tracking imaging. Methods The left anterior descending coronary arteries of 8 dogs were first ligated for 20 min,and then reperfusde for 120 min;two-dimensional echocardiography was applied to measure the changes of the left ventricular reserve function,the pipeline function and the auxiliary pump function,respectively,before ligation,ligation period,immediately after reperfiision,and also 30,60,90,120 min after the reperfusion. Results The left atrial function and reserve pipe function indices in ligation period,immediately after reperfusion,30,60,90,120 min were lower than before ligation period, while the auxiliary pump function index were higher than before ligation period,the differences were statistically significant(P < 0.05). Conclusion Two dimensional speckle tracking imaging technology can not only detect canine stunned myocardium during ischemia, but also evaluate the changes of left atrial function in different periods after reperfusion.关键词
