超声心动图斑点追踪成像在冠心病预后评估中的价值及进展

冠状动脉粥样硬化性心脏病（CAD）是临床上最常见的心血管疾病之一，目前，其发病率和死亡率呈逐年上升趋势，利用无创方法建立有效的预后评价体系一直是临床研究的热点。超声心动图是目前临床上应用广泛的心脏成像技术，具有便捷、无创及实时性等优点，能够为CAD患者预后与生存评估提供有价值的诊疗信息。相比于常规超声心动图，斑点追踪成像（STI）更具诊断高效性和临床实用性，能提供丰富的定性、定量多参数信息。本文分别从左室二维、左室三维、左房三个角度就STI多参数信息在冠心病预后评估中的价值及进展作一综述。

The value and progress of echocardiographic speckle tracking imaging in the prognostic assessment of coronary artery disease

Coronary artery disease (CAD) is one of the most common cardiovascular diseases in clinical practice. Currently, its morbidity and mortality rates are increasing year by year, and the use of non-invasive methods to establish an effective prognostic evaluation system has been a hot spot in clinical research. Echocardiography is a widely used clinical cardiac imaging technique with the advantages of being convenient, non-invasive and real-time, and can provide valuable diagnostic information for the prognosis and survival assessment of CAD patients. Compared with conventional echocardiography, speckle tracking imaging (STI) is more diagnostically efficient and clinically useful, providing a wealth of qualitative and quantitative multiparametric information. This article reviews the value and progress of STI multiparametric information in the prognostic assessment of coronary artery disease from three perspectives: left ventricular two-dimensional, left ventricular three-dimensional and left atrial.
