Characteristics of the Patients at rest.

Data are expressed as mean value ± SD or median [interquartile range] or), or absolute numbers (percentage).
*p<0.05 for comparison between controls and group 1 versus group 2.
†Maximal systolic velocity at the tricuspid annulus by tissue Doppler velocity
A =  late transmitral flow velocity; BSA  =  body surface area; DBP  =  diastolic blood pressure; DT  =  deceleration time; E =  early diastolic transmitral flow velocity; E/e'  =  ratio of the early diastolic transmitral flow velocity to early diastolic mitral annular velocity; LA  =  left atrium; LVDd  =  left ventricular end-diastolic diameter; LVEF  =  left ventricular ejection fraction; LVSd  =  left ventricular end-systolic diameter; SBP  =  systolic blood pressure, SPAP  =  systolic arterial pulmonary pressure.
