2.2. Doppler Echocardiography

Doppler echocardiography was performed using the “Xario 100” scanner (Toshiba, Tokyo, Japan) with a 2.5 MHz sensor and detection of standard parameters. The systolic function and ejection fraction of the LV were assessed by M-mode echocardiography. The parameters of the hemodynamics at the valves were assessed by Doppler measurements. Relative left ventricular posterior wall thickness (RPWT) was detected by A. Ganau [19]. Left ventricular mass (LVM) detected by Devereux R.B [20]. Left ventricular myocardium mass index (LVMMI) was detected by P. Gosse [21].
