Values are mean ± SD.

^aP < 0.05, significant within-group difference.

DD: Diastolic dysfunction; DTe: Deceleration time of E wave; E': Mean value of the septal and lateral e' of TDI of the mitral annulus; Ε/Α: Ratio of the E and A waves of the transmitral inflow; E/E': Ratio of the E wave to E' wave; EF: Ejection fraction; LAVi: Left atrial volume index; RVSP: Right ventricular systolic pressure; VO_2peak: Peak oxygen uptake; W_peak: Peak workload.
