Mitral annular displacement (MAD) is a function of global shortening deformation of left ventricle (LV) and mirrors sub\u2010endocardial ischemia in CAD. The aim of this study was to ascertain if MAD can predict the presence of CAD in patient presenting with suspected CSAP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This cross\u2010sectional study was conducted on patients with suspected CSAP (n\u00a0=\u00a0140) and preserved LV function without apparent wall motion abnormalities during the study period. We excluded patients with prior heart disease (valvular, ischemic), presenting with acute coronary syndrome, arrhythmia, heart failure, and poor imaging. All the patients were subjected to speckle tracking echocardiography (STE) and CAG. Average MAD and normalized MAD were calculated by automated function imaging (AFI), and receiver operating characteristic (ROC) curve was plotted for presence of significant CAD considering CAG as gold standard.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results showed that both average MAD (4 segment) and normalized MAD were significantly reduced (<jats:italic>P\u00a0<\/jats:italic>=\u00a0&lt;.001) in patients with significant CAD (n\u00a0=\u00a081). In ROC analysis, area under curve (AUC) for predicting significant CAD in patients of CSAP was better for normalized MAD (0.88) compared to average MAD (4 segment, 0.85).The optimal cutoff of normalized MAD and average MAD for detection of significant CAD were \u226415.3% (sensitivity 90.1%, specificity 79.7%) and \u226411.19 (sensitivity 84%, specificity 69.5%), respectively.
