Left atrial strain parameters are able to predict presence of atrial fibrillation

Original language description

Background: Three-dimensional speckle-tracking echocardiography allows evaluation of left atrial function, left atrial function has been assessed in various diseases for prognostication [1]. Atrial fibrillation (AF) is most common arrhythmia, and one of its manifestations is increased left atrial filling pressure and left atrial dilatation. Methods: Echocardiography loops were collected between December 2019 and December 2021, only valid atrial loops, and sinus rhythm during examination. Spearman test was used for correlation matrices of left atrial parameters; uni- , multivariate and binary logistic regression to predict presence or absence of atrial fibrillation. Results: Atotal of 116 patients (50% females) aged 76.9±11.2 were included in the analysis. Males and females differed in anthropometric and other clinical parameters. Intra- and interobserver variability was close to 1% since most of the measurements are semi-automatized. 2D and 3D left atrial volumes correlated significantly (r=0.8, P<0.0001, Fig.1). Almost all left atrial strain measurement uni- and multivariately predicted the presence of atrial fibrillation, binary logistic regression identified two most significant parameters (left atrial longitudinal strain reservoir and conduit phase, LASr,LAScd,P=0.042,P=0.044,respectively, Fig.2).LASr issignificantly greater in patients without history of AF vs patient with AF history, (16±16, 10.5±7.1, respectively, P=0.012). The probability of sinus rhythm increases linearly with the increasing value of LASr. Conclusion: Left atrial longitudinal strain was able to differentiate patients with paroxysmal atrial fibrillation as compared to patients without history of this arrhythmia.
