摘要
非ST段抬高急性冠脉综合征(Non-ST segment elevation acute coronary syndrome,NSTE-ACS)是不稳定斑块基础上急性血栓形成,冠脉狭窄程度骤然加剧,冠脉血流减少导致心肌氧供应的直接减少为病理基础的一组临床综合征,好发于老年人,常累及多支血管,由于其心电图及常规超声心动图表现不典型,容易给临床带来困扰,斑点追踪成像(speckle tracking imaging,STI)无角度依赖性分别评价左室纵向、圆周、径向、扭转功能,为敏感评价左室功能早期改变提供了新的方法,本文对非ST段抬高急性冠脉综合征患者的临床特点以及斑点追踪技术的临床应用研究进展进行了综述。
Non-ST segment elevation acute coronary syndrome is a clinical syndrome that when unstable plaque is formed on the basis of acute thrombosis, coronary stenosis sharply increased, coronary blood flow due to reduced myocardial oxygen direct supply reduction, it often occurs in the elderly and drags in multi-vessel, because its routine electrocardiogram and echocardiography was not typical, so it is easy to bring trouble to the clinical, speckle tracking imaging which is no angular dependence respectively assess the left ventricular longitudinal, circumferential and radial, reverse function, provides a new method for the assessment of early changes of left ventricular function sensitively, the paper summary the clinical Features of non-ST segment elevation acute coronary syndrome and clinical application of speckle tracking technology.
