Abstract

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 con- trols. 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 asso- ciation 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. (Anadolu Kardiyol Derg 2014; 14: 128-33)
