Abstract

Background:Two-dimensional speckle tracking (2D-ST) echocardiography is a promising new techniquefor imaging. Aim of the work:to evaluate feasibility of real-time 2D‐ST echocardiography of the aortic root in relation to aortic stiffness for the early prediction of atherosclerosis in vascular beds. Patients and Methods:This cross-section study was carried out on 50 patients complained of chest pain.All patients were subjected to blood pressure (BP) and aortic stiffness index measurement, invasive coronary angiography, resting transthoracic echocardiography, aortic speckle tracking echocardiography (STE),Carotid intima - media thickness (IMT) and ABI. Patients weresubdivided into two groups, atherosclerotic group including 32 patients have lesion in one or more vascular bed and non-atherosclerotic group including 18 patients have no affected vascular beds. Results: Aortic distensibility and circumferential ascending aortic strain (CAAS)had a significant negative relationship with Gensini score (r= -0.717, P
