Echocardiographic indices for all patients.

<p>Data are mean ± SD or frequencies (%). Analysed using independent samples t-test or χ².LVEF, LV ejection fraction; LA, left atrium; LAVI, left atrial volume index corrected to body surface area; LVMI, LV mass index corrected to body surface area; LVH, left ventricular hypertrophy; E/A, the ratio of peak early to late transmitral ventricular filling velocities; IVRT, isovolumic relaxation time; E/E’, ratio of early transmitral flow velocity to annular mitral velocity (averaged of septal and lateral).
