[Variations of atrial natriuretic peptide in hemodialysis].
In this study the variations of atrial natriuretic factor (ANF) in hemodialyzed patients were correlated to blood volume and atrial cavities diameter. At the end of the dialytic process we observed a significant reduction of ANF plasma levels and body weight. This data established the crucial role of blood volume in the regulation of ANF secretion-suppression. In addition the fluctuations recorded in the heart atrial diameters reveal their sensitivity to blood volume variations induced by hemodialysis.
