Objective |
To measure left atrial (LA) diameter in normotensive, overweight children and to determine the variables that independently influence LA diameters.
Study design |
A cross-sectional study on 22 overweight children (age, 13.40 ± 1.22 years) and 18 control children (age, 13.40 ± 2.19 years) was performed. LA diameter, left ventricular (LV) geometry, and LV systolic/diastolic function were measured through echocardiography. Data were compared between the two groups. Multiple regression analysis, with LA diameter as dependent variable, was conducted.
Results |
In the overweight group, LV diastolic dimension, LV mass index, peak S, S/D ratio, Am, maximal LA diameter (34.1 mm vs 25.4 mm), middle LA diameter (26.9 mm vs 18.1 mm), and minimal LA diameter (22.5 mm vs 16.1 mm) were increased and Em/Am ratio was decreased. In multiple regression analysis, body mass index (R2 = 0.7040, 0.7085, 0.7406 in respective maximal, middle, and minimal LA diameter) and systolic blood pressure (R2 = 0.0540, 0.0477, 0.030 in respective maximal, middle, and minimal LA diameter) were significant independent correlates of all three measures of LA diameter.
Conclusions |
LA diameter in normotensive overweight children is increased. Body mass index and systolic blood pressure were significant correlates of LA diameter.
