Value of indicators of longitudinal deformation of the left atrium in patients with chronic heart failure

Abstract

Modern technologies for assessing myocardial strain by means of speckle-tracking echocardiography allow to analyze not only the ventricles of the heart, but also the left atrium (LA). Evaluation of LA strain in patients with chronic heart failure (CHF) can be useful in the terms of diagnostic in patients with first-time symptoms that may indicate the onset of heart failure with a preserved left ventricular ejection fraction. In patients with CHF, LA strain may be important for evaluating the prognosis. Assessment of the dynamics of LA strain in patients with heart failure may indicate the course of CHF and the effectiveness of therapy. The purpose of this article is to analyze the data on the significance of LA longitudinal strain indicators for the diagnosis and management of patients with CHF.
