KEY WORDShypertension, left atrium, speckle tracking echocardiography, strain, strain rate Changes in the three phases of left atrial (LA) function have not been well studied in hypertension. We studied phasic function of LA by speckle tracking echocardiography (STE) in hypertension. Sixty-one consecutive untreated hypertension patients and 32 sex-and age-matched healthy participants were included. Two-dimensional (2D) images obtained from apical four-chamber and two-chamber views were used for STE analysis of LA. LA peak positive strain (39.8 AE 10.9 vs. 45.3 AE 12.7 %, p Z 0.031), peak negative strain (À2.2 AE 1.5 vs. À3.0 AE 1.9 %, p Z 0.029), and conduit strain rate (À2.0 AE 0.5 vs. À2.4 AE 0.6 1/s, p Z 0.005) were significantly decreased in hypertension. Twenty hypertensive patients (32%) had diastolic dysfunction. Positive strain (34.8 AE 7.2 vs. 42.2 AE 11.6 %, p Z 0.012) and conduit strain rate (À1.7 AE 0.4 vs. À2.2 AE 0.5 1/ s, p < 0.001) were decreased in patients with diastolic dysfunction. Only conduit strain rate was independently associated with diastolic dysfunction (OR 11.9, p Z 0.026) after multivariable analysis. LA phasic function is decreased in untreated hypertension. Decreased LA conduit function is associated with diastolic dysfunction in hypertension. ª

“…If the automatically obtained tracking segments were adequate for analysis, the software system was allowed to read the data, whereas analytically inadequate tracking segments were either corrected manually or excluded from the analysis. In STE analysis for LA, peak global LA strain during reservoir phase (LAs-Strain) and LA strain during LA contraction (LAa-Strain) were obtained (10).…”

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.
