Abstract Speckle-tracking echocardiography (STE) is a new non-invasive ultrasonic imaging method that allows an objective and quantitative valuation of regional and global function of myocardium independently from heart translational movements and insonation angle through estimation of longitudinal strain both regional & global. Although MRI may be considered the reference standard in estimating myocardial deformation, its routine use is limited by its high costs, poor accessibility, relative difficulty of acquisitions, and time consuming. Longitudinal strain offers a quantitative assessment of myocardial deformation of each left ventricular segment, also permits early systolic dysfunction detection in patients with a preserved LVEF. This may help in predicting IHD through non-invasive method. In the present study, we tried to assess accuracy of STE compared to conventional coronary angiography. Study design is Cross sectional survey, conducted in the open heart Center of Al-Sadr Hospital; Najaf City. Study population was Patients with Ischemic heart disease referred for conventional coronary angiography. 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%. Significant correlation between RLS for the basal and mid part of the main six segments and the culprit artery (P value = 0.0001) Top Keywords Ultrasonic imaging, Speckle-tracking echocardiography, Regional longitudinal strain.
