Two-year follow-up of the left ventricular systolic function. EF, ejection fraction; MAPSE, mitral annulus systolic motion; lateral s′, tissue Doppler imaging systolic wave velocity. EF measured by the Simpson’s method suggested normokinetic left ventricular systolic function at baseline and during the follow-up period in the monophasic group (significantly lower, but normal EF); however, it was lower in the polyphasic group compared to the other groups. In line, MAPSE was in the normal range at baseline and during the follow-up in the monophasic group; however. it was found to be significantly lower in the polypasic group compared to the control and the baseline group. Additionally, a lower lateral s′ wave velocity showed LV systolic dysfunction already at baseline and at the end of the follow-up period in both groups, as well. * P<0.05 vs. control, # P<0.05 vs. baseline, & P<0.05 vs. monophasic
