摘 要 目的:本试验是利用声学密度定量技术(AD-IBS)预测再灌注心肌存活。方法:在发病当天,发病后第3天,第21天分别对20例急性心肌梗塞患者进行AD-IBS检查。结果:标化CVIB在发病后第3天有所恢复(不依赖于室壁运动的恢复)的梗塞区心肌,其在发病后第21天的室壁增厚率可达到与正常心肌区无明显差异。结论:故可认为心肌梗塞后标化CVIB可早期预测再灌注心肌的存活。

ABSTRACT Objective:In thisstudy,predicting the viability of reperfused myocardium at the early stage of acutemyocardial infarction(AMI)will be evaluated by integrated backscatter(IBS).Methods:Twentypatients with AMI who were given reperfusion therapy received AD-IBS analysis on the dayof onset,the 3rd day and the 21st day after the onset of the symptoms.Results:Theinfarcted myocardium with recovered normalized CVIB regain good wall thickening on thr21st day.Conclusions:The normalized CVIB on the 3rd day of AMI,even if there was norecovery of wall motion,can predict the wall thickening on the 21st day.
