Abstract：Objective To explore the correlation between body mass index (BMI) and left atrial volume (LAV).Methods Patients undergoing transthoracic echocardiography from January 2012 to April 2012 were consecutively enrolled.The weight, height, and blood pressures were recorded;the left ventricular diameter (LVD), left ventricular posterior wall thickness (LVPW), left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), left ventricular fractional shortening (LVFS) were measured by M-mode ultrasound;the left ventricular ejection fraction (LVEF) and left ventricular volume (LAV) were assessed by Simpson method.The correlations between BMI and LAV were analyzed.Results A total of 476 patients were finally enrolled, including 268 male and 208 female.The patients were divided into obesity group (BMI ≥25.0 kg/m2, 289 cases) and non-obesity group (BMI ＜ 25.0 kg/m2, 187 cases) , the LAV in obesity group was significantly higher than that in non-obesity group [(26 ± 6) ml vs (24 ± 7) ml] (P ＜ 0.01).Multivariate linear regression showed that BMI was significantly correlated with LAV after adjustment of other potential risk factors (β =0.37, P ＜ 0.001);in male and female, the same results were obtained (male :β =0.39, P ＜ 0.001;female :3 =0.31 ,P =0.017).Conclusion BMI is an independent predictor of LAV increasing in both male and female.
