Abstract Calculation of longitudinal movement and distortion are consequently the major subtle indicators particularly in cases with coronary disease. a non-invasive, simple technique to get better assortment of cases that are denoted for coronary artery is potentially needed. The aim of the present study is to assess the accuracy of diagnosis by global longitudinal strain, (GLS) gained by speckle tracking echocardiography (STE) in estimation of the existence, degree and severity of coronary artery disease in comparison to conventional coronary angiography. A Cross sectional survey, conducted in the open heart Center of Al-Sadr Hospital; Najaf City. In this study, 228 patients; age range was 37–77 years, with a mean of 56.71±9.736 years. Of them 65% were males. The sensitivity of STE was 95.3%, specificity was 75%, PPV was 95.3%, NPV was 75%, and accuracy rate was 92.1%. The mean cutoff point of GLPS was-15.39 while +LR was 3.86 and-LR 0.33. ROC analysis generally revealed that good and very good AUC value for the six main segments also the same thing for the sub segments while AUC of GLPS was 0.748. In conclusion, goodness of the diagnostic test and there is no difference from the gold standard method in addition STE have no serious complication on the patients.
