Diagnostic Value of Regional Wall Motion Abnormalities on Resting Transthoracic Echocardiography for Coronary Artery Disease.

Purpose: Regional wall motion abnormality (RWMA) on transthoracic echocardiography (TTE) is used as a clinical decision-making tool to assess systolic function, but there is limited data regarding the validity of this tool to predict obstructive coronary artery disease (CAD). This study evaluates the utility of RWMA on TTE for detecting obstructive CAD in patients with no prior CAD history.

Methods: We retrospectively reviewed charts of adults who underwent resting TTE and coronary angiography within 30 days, analyzing RWMA in relation to angiographic luminal stenosis.
