Renal Ultrasonography Predicts Worsening Renal Function in Patients with Heart Failure Under Tolvaptan Administration

ESC Heart FailPublished Post hoc sub-analysis of a single-centre randomised trial

Authors' conclusion

Tolvaptan increased the PSV and EDV of the interlobar artery, which may mean tolvaptan increased renal blood flow. The renal artery AT may be a surrogate for worsening renal function.

Study context

Population
Patients with decompensated HF, January 2014–March 2019
Participants
201 patients
Comparison
Early vs late tolvaptan administration; renal ultrasonography before vs after tolvaptan
  • Earlyn = 104
  • Laten = 97reference
Methodological detailsprospectively randomized
  • Prospectively randomized

Primary result

As reported in the abstract

Change in interlobar artery velocities, before vs after tolvaptan
  • After tolvaptan vs Before tolvaptan: P = 0.002
  • After tolvaptan vs Before tolvaptan: P = 0.002
  • After tolvaptan vs Before tolvaptan: P = 0.001
  • After tolvaptan vs Before tolvaptan: P = 0.003

Further findings

Renal artery acceleration time (AT) and estimated glomerular filtration rate (eGFR)

Δmax AT negatively correlated with eGFR, beta = −0.2354
P = 0.044
Δmean AT negatively correlated with eGFR, beta = −0.2477
P = 0.035

Urine output, oral water intake, water intake–urine volume difference

Significantly increased during tolvaptan administration

Body weight, BP, heart rate, eGFR; renal artery peak-systolic velocity (PSV), AT and resistance index

Changes comparable in both groups
