Echocardiographic data at rest.

Median values [interquartile range]. E/A; early and atrial transmitral flow fraction, DT; deceleration time, E/E′; early transmitral flow and early tissue Doppler velocity fraction, LV-MPI; left ventricular myocardial performance index, RV-MPI; right ventricular MPI. The non-parametric Mann-Whitney U-test was used to compare the median values for the two independent groups.
