INTRODUCTION: Inpatient management of patients with heart failure (HF) and renal impairment is challenging. We sought to evaluate the role of pocket ultrasound (US)-guided management of this patient population.

METHODS: We prospectively included patients with acute HF exacerbation and renal impairment admitted to the HF service in our University hospital from January 2017 to August 2018. We compared the outcomes of patients who received US-guided management with those who received standard of care management. The main study outcome was the change in estimated glomerular filtration rate (eGFR). Multivariable logistic analysis was used to adjust for basic demographics and risk factors.

RESULTS: A total of 211 patients with renal impairment presenting with acute HF exacerbation (mean age 66.8 ± 14.6 years, 41% females, 62% white) were enrolled in the study, of whom 69 (32.7%) received US-guided management and 151 (68%) received standard of care management. The change in the eGFR was significantly lower in US-guided group than in the group receiving standard of care (1.1 ± 4.3% vs. - 11.15 ± 2.9%; p = 0.04). No significant difference was observed between the patient groups in the length of stay (6.45 ± 0.38 vs. 6.44 ± 0.56; days; p = 0.98) and in the 30-day HF readmission rate (hazard ratio 1.27, 95% confidence interval 0.28-5.6; p = 0.75).

CONCLUSION: Ultrasound-guided management of patients admitted with acute HF exacerbation and renal impairment may be beneficial in preserving kidney function. US provides a simple easily accessible tool to guide the management of patients with HF.
