Emergency physician use of tissue Doppler bedside echocardiography in detecting diastolic dysfunction: an exploratory study

Introduction This study evaluates the agreement between emergency physician (EP) assessment of diastolic dysfunction (DD) by a simplified approach using average peak mitral excursion velocity ( e ʹ A ) and an independent cardiologist’s diagnosis of DD by estimating left atrial (LA) pressure using American Society of Echocardiography (ASE) guidelines. Methods This was a secondary analysis of 48 limited bedside echocardiograms (LBE) performed as a part of a research study of patients presenting to the Emergency Department (ED) with elevated blood pressure but without decompensated heart failure. EPs diagnosed DD based on e ʹ A
