Abstract: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.
