Obesity and abnormalities in echocardiographic parameters.

Dear Editor,

We congratulate the authors of the manuscript published under the title "The Impact of Isolated Obesity on Right Ventricular Function in Young Adults"[1]. We believe that the hemodynamic changes that characterize obesity could modify the echocardiographic parameters found abnormal in this study, that is, increased volemia would readjust the parameters of ventricular function without any concomitant changes in ventricular function. What is the authors' opinion about this analysis?[2].
