Relationships among pulmonary capillary wedge pressure, dry weight and natriuretic peptide in patients undergoing hemodialysis: a three-dimensional speckle tracking echocardiography study
2020
Background
Although the evaluation of fluid status in hemodialysis (HD) patients is useful, relationship among pulmonary capillary wedge pressure (PCWP), dry body weight (DW) and natriuretic peptide has not been elucidated. In addition, there has been no objective marker for instantaneously monitoring hemodynamic improvement in response to HD. We previously reported that PCWP and time constant of left ventricular pressure decline (Tau) can be noninvasively estimated (ePCWP and eTau) by speckle tracking echocardiography (STE). The aim of this study was to elucidate the relationship among ePCWP, eTau, DW and natriuretic peptide in patients undergoing HD.
