Predictive value of normal left atrial volume in stress echocardiography.
OBJECTIVES Our objective was to evaluate whether normal left atrial volume index (LAVI) is a predictor of a normal stress echocardiogram and thus a predictor of low ischemic risk. BACKGROUND Left atrial enlargement is closely related to the chronicity and intensity of the burden of increased ventricular filling pressure. Typically ischemic heart disease (IHD) has a long period of subclinical ...
متن کاملThe additive value of three-dimensional derived left atrial volume and carotid imaging in dobutamine stress echocardiography.
AIMS to evaluate whether the three-dimensional (3D) left atrial volume index (LAVI) and/or the presence of carotid plaques (CP) can predict the result of dobutamine stress echocardiography (DSE), thereby aiding interpretation. METHODS AND RESULTS we studied 130 patients (52 male, mean age 63 ± 11 years) with normal resting wall motion (WM) undergoing DSE. All patients had the end-systolic 2D ...
متن کاملRespiratory influence on left atrial volume calculation with 3D-echocardiography
BACKGROUND Left atrial volume (LAV) estimation with 3D echocardiography has been shown to be more accurate than 2D volume calculation. However, little is known about the possible effect of respiratory movements on the accuracy of the measurement. METHODS 100 consecutive patients admitted with chest pain were examined with 3D echocardiography and LAV was quantified during inspiratory breath ho...
متن کاملPrognostic value of left atrial volume index in hemodialysis patients.
OBJECTIVE To evaluate the prognostic value of left atrial volume index (LAVi) in the clinical course of hemodialysis (HD) patients, compared with previously established echocardiographic and clinical parameters. METHODS Echocardiograms were obtained from 118 hemodialysis patients, who were then followed for 19 +/- 8 months. Study endpoint was a composite of all-cause mortality and nonfatal ca...
متن کاملPrognostic value of left ventricular volume response during dobutamine stress echocardiography.
AIMS An abnormal left ventricular volume response during dobutamine echocardiography identified patients with severe coronary artery disease. The aim of the study was to assess the prognostic value of left ventricular volume changes during dobutamine stress echocardiography in 136 patients. METHODS AND RESULTS Endpoints were defined as spontaneous cardiac events at follow-up. Left ventricular...
