Abstract:
The aim of this study is to evaluate whether isovolumic relaxation flow propagation velocity (IRFPV), a newly proposed relaxation parameter, is independent of load alterations. Thirty-nine uremic patients (21 men; age 62 +/- 10 y) who underwent echocardiography 1 h before and 1 h after hemodialysis (HD) were included. After HD, body weight, systolic blood pressure, early transmitral filling wave velocity (E), early diastolic mitral annular velocity (Ea) and early diastolic inflow propagation velocity (EPV) decreased significantly (p
