^aValues are expressed as before/after haemodialysis. ^bP < 0.05 versus baseline. ^cP < 0.05 versus patients with preserved LV systolic function, defined as a LV ejection fraction ≥ 50% (Mann-Whitney test). BP, blood pressure; DT_E, E wave deceleration time; HR, heart rate; IVRT, isovolumic relaxation time; LV, left ventricular; LVEDVI, left ventricular end-diastolic volume index; V_max, maximal velocity; Vp, propagation velocity.
