Data are presented as mean ± standard deviation or median [interquartile range]. *, P<0.05 compared with T0. T0: before first discharge; T1: 1 month after discharge; T3: 3 months after discharge; T6: 6 months after discharge. LVEDD, left ventricular end-diastolic diameter; LVESD, left ventricular end-systolic diameter; E/A: the ratio of the rate of blood flow for rapid ventricular filling in early diastole to the rate of blood flow in mid- to late diastole; E/e': the ratio of peak early diastolic mitral flow velocity E to peak early diastolic mitral annular velocity e'; 2D, two-dimensional; LVEF, left ventricular ejection fraction; SBP, systolic blood pressure; DBP, diastolic blood pressure; LVGLS, left ventricular global longitudinal strain; GWI, global work index; GCW, global constructive work; GWW, global wasted work; GWE, global work efficiency.
