心脏声学造影在非ST段抬高型急性冠状动脉综合征中的应用

Application of Contrast Echocardiography in Patients with Non-ST Segment Elevation Acute Coronary Syndrome

非ST段抬高型急性冠状动脉综合征由于缺乏特异的检查手段,容易造成漏诊、误诊,导致治疗延误,甚至引起患者死亡。因此开发有效的鉴别诊断方法具有重要意义。心脏声学造影是一种可以在急诊室和胸痛中心快速施行的无创影像检查技术,该技术可在床旁同时评价心脏室壁运动和心肌灌注情况而用于各类冠状动脉疾病的诊断。现就心脏声学造影在非ST段抬高型急性冠状动脉综合征中的应用情况做一综述。

Due to the lack of specific testing methods,non-ST elevation acute coronary syndrome （NSTE-ACS） can be easily misdiagnosed,which can cause to delayed treatment or death.Therefore,it is highly important to find an effective way to distinguish differential diagnosis.Contrast echocardiography（CE） is a form of noninvasive imaging technology that can be rapidly conducted in an emergency and chest pain center.Evaluating myocardial wall motion and myocardial perfusion simultaneously at the patient＇＇s bedside,CE can be used to diagnosis variety of coronary heart diseases.In this paper,we will review the application of CE in NSTE-ACS.
