“…The feasibility and reproducibility of STE for the study of LA mechanics have been validated in several studies (28,(46)(47)(48)(49), and can be obtained in ~90% of cases. The major limitation is the necessity for adequate 2 dimensional image quality and acquisition at a relatively high frame rate (4,5).…”

Abstract:The left atrium has an important role in modulating left ventricular filling and is an important biomarker of cardiovascular disease and adverse cardiovascular outcomes. While previously left atrial (LA) size was utilised, the role of LA function as a biomarker is increasingly being evaluated, both independently and also in combination with LA size. Strain analysis has been utilised for evaluation of LA function and can be measured throughout the cardiac cycle, thereby enabling the evaluation of LA reservoir, conduit and contractile function. Strain evaluates myocardial deformation while strain rate examines the rate of change in strain. This review will focus on the various types of strain analysis for evaluation of LA function, alterations in LA strain in physiological and pathologic states that alter LA function and finally evaluate its utility as a prognostic marker.

“…The development of new echocardiographic techniques, such as two-dimensional speckle tracking echocardiography (STE) has enhanced the ability to evaluate left atrial (LA) function by using quantitative assessment of myocardial deformation. Studies have indicated that STE is a feasible and reproducible method in assessing LA function (4,5). In some patient groups, as paroxysmal or permanent AF, LA strain measurements were found to be associated with episodes of paroxysmal AF and stroke risk in follow up (6,7).This method may provide a more direct evaluation of LA myocardial contractility and passive deformation (5).…”

Objective: We aimed to investigate left atrium (LA) function by speckle tracking echocardiography in patients with metabolic syndrome (MetSyn) and to show a possible relationship between the severity of MetSyn and LA function and to determine the predictors of low strain in MetSyn patients. Methods: Our study design was observational and cross-sectional design consisted of 80 MetSyn patients without overt diabetes and 50 controls. The patients were classified into three groups based on the number of MetSyn criteria. The peak LA strain at the end of the ventricular systole (LAs-strain) as well as the LA strain with LA contraction (LAa-strain) was obtained. Correlation analysis performed to assess the association of LA strain parameters with the severity of MetSyn and logistic regression analysis performed to assess the relationship of low LA strain with MetSyn. Results: Both LAs (37.5±8.7 vs. 26.0±10.2, p<0.001) and LAa (19.9±6.3 vs. 13.0±6.4, p<0.001) strain measurements were found to be significantly decreased in patients with MetSyn when compared to the control group. Moreover, both LAs and LAa were found to be significantly decreased with the increasing severity of the MetSyn. A multiple logistic regression analysis demonstrated that the presence of MetSyn [OR:0.26 (95% CI 0.06-0.89), p=0.032] and left ventricular ejection fraction [OR:1.14 (95% CI 1.03-1.27), p=0.021] were independent predictors of LAs strain. Conclusion: MetSyn is associated with reduced LAs strain and LAa strain representing LA reservoir and pump function, respectively. Furthermore, LA mechanical function decreases even more with the increasing severity of the MetSyn.
