Assessment of Longitudinal Left Ventricular Function in Patients with Coronary Artery Ectasia by 2D Speckle Tracking Echocardiography

Abstract

ABSTRACT Background: Coronary artery ectasia (CAE) is one of the uncommon cardiovascular disorders. CAE is one of the known risk factors for acute coronary syndrome, its incidence ranges from 1.5%-5% of patients undergoing coronary angiography, with predominance in males. Coronary artery ectasia (CAE) is defined as dilatation of an arterial segment to a diameter at least 1.5 times that of an adjacent normal artery and involves at least one third of the affected artery. The exact pathogenesis of CAE is not well established; however, Coronary atherosclerosis is detected in more than 50% of the patients. Objective: To evaluate global left ventricle longitudinal strain by 2D speckle tracking echocardiography in patients with coronary artery ectasia and without significant (>50%) coronary artery stenosis.
