Values represent means ± SD, median (minimum-maximum). DT: E wave deceleration time; IRT: isovolumetric relaxation time; LVEDP: left ventricle end diastolic pressure (by Nagueh formula); PV color: transmitral color propagation velocity; GLS: left ventricle global longitudinal strain. (Student’s -test), (Mann-Whitney test).
