Abstract

Background: Acute kidney injury (AKI) is a frequent complication among patients with acute decompensated heart failure, with reported incidence rates ranging from 16.6% to 58% in both domestic and international studies and is associated with prolonged hospitalization and worse clinical outcomes.

Methods: A cross-sectional descriptive study was conducted on 99 ADHF patients diagnosed at Can Tho Central General Hospital from 2022 to 2024.

Results: The incidence of AKI in ADHF patients was 42.4%. Among them, 54.8% achieved full recovery, 42.9% partial recovery, and 2.4% showed no recovery. Mortality rates were highest in stage 3 AKI (20.0%), followed by stage 2 (11.1%) and stage 1 (3.6%). Dobutamine treatment significantly improved AKI recovery (68.0%) compared to non-recovery (32.0%) with a p-value of 0.037.

Conclusions: AKI is common in ADHF patients, with a high recovery rate. Mortality varies by AKI stage, being highest in advanced stages. Dobutamine is associated with better recovery outcomes.
