Abstract:
Background : Speckle - tracking echocardiography is a new noninvasive ultrasound imaging technique that allows for evaluation of global and regional myocardial function.Aim of the Study : to evaluate the accuracy of regional(segmental) longitudinal strain by 2D - STE for pick up culprit vessels in ACS by detecting ischemic segments of the corresponding territories and its severity compared with coronary angiography as a gold standard, in patients with acute coronary syndrome .Patients and Methods : A cross sectional study was held in Baghdad teaching hospital from March 2017 to March 2018, consisted of patients with acute coronary syndrome(ACS) underwent 2D - STE for left ventricular regional longitudinal strain(RLS) immediately before invasive coronary angiography .Results : Fifty patients who fulfilled the inclusive criteria were enrolled in this study. The mean age 57.2 (± 7.9) years; and male : female ratio 1.9 : 1. Regional Longitudinal strain - speckle tracking showed 38 patients had CAD and 12 patients had no CAD, Versus coronary angiography which showed 29 patients had CAD while 21 patient had no CAD or non significant lesions.The validity of RLS according to coronary angiography showed sensitivity 100%, specificity 57.1% ,PPV 76.3%,NPV 100%, and accuracy 82%.Conclusion : The current study revealed that (RLS) Speckletracking echocardiography technique has high sensitivity but with relatively low specificity in diagnosis of coronary artery disease in patient with acute coronary syndrome.
