Prognostic Impact of Induced Natriuresis in Acute Decompensated Heart Failure and Its Association with Intraabdominal Pressure and Other Congestion Markers: A Multimodal Approach to Congestion Assessment.

However, after the first 48 h of admission, patients with a greater diuretic response on admission (NaU > 80 mmol/L) showed a trend of having fewer pulmonary b-lines (12 vs. 15; p = 0.084), a lower IVC diameter (18 mm vs. 22 mm; p = 0.009), and lower IAP values (11 mmHg vs. 13 mmHg; p = 0.041).

We did not find differences in congestion at baseline, but those patients with a good natriuretic response (>80 mEq/L) showed a clear trend of decongestion in terms of in ultrasound and through biomarkers, and they had a significant fall in IAP and fewer outcomes than those with natriuresis below that level.
