Strain/strain rate imaging of impaired left atrial function in patients with metabolic syndrome

Left ventricular (LV) dysfunction has been demonstrated in patients with metabolic syndrome (MetS). However, alterations in left atrial (LA) function in MetS are unknown. We aimed to use strain/strain rate (SR) imaging to investigate the effect of MetS on LA function. A total of 177 MetS patients an...

Description
Summary:Left ventricular (LV) dysfunction has been demonstrated in patients with metabolic syndrome (MetS). However, alterations in left atrial (LA) function in MetS are unknown. We aimed to use strain/strain rate (SR) imaging to investigate the effect of MetS on LA function. A total of 177 MetS patients and 156 normal subjects underwent echocardiography. Strain and SR tissue Doppler imaging values were used to evaluate LA function. Partial correlation and multiple stepwise regression analyses were used to determine the risk factors for impaired LA function. Compared with the controls, the MetS patients showed significantly lower levels of mean strain, mean peak systolic SR and mean peak early diastolic SR (P
