本研究旨在探讨斑点跟踪超声心动图(左房应变)和多普勒测量(E/E‘值)与直接测量左心室(LV)舒张末压力(LVEDP)在不同射血分数分层患者中的相关性。选择这一人群是为了有四组患者，每组20人，每组具有不同的左心室射血分数(>；55%、45%-54%、30%-44%和
BackgroundThis study aimed at exploring the correlation of left atrial longitudinal function by speckle tracking echocardiography (left atrial strain) and Doppler measurements (E/E' ratio) with direct measurements of left ventricular (LV) end-diastolic pressure (LVEDP) in patients stratified for different values of ejection fraction.MethodsThe study population was 80 stable patients with sinus rhythm undergoing cardiac catheterization. This population was selected in order to have four groups of 20 patients each with different LV ejection fraction (>55%, 45-54%, 30-44%, and
