Abstract
AIMS: In acute heart failure (AHF), assessment of renal function comprises estimation of glomerular filtration rate (eGFR), which does not provide any information about renal sodium/water handling. We describe the interactions between urinary sodium concentration and eGFR to better characterize AHF patients. METHODS AND RESULTS: In 219 patients with AHF, spot urine sodium (UNa+ ) and eGFR were assessed on admission, day 1 and day 2 of hospitalization. We found no correlation between UNa+ and eGFR (calculated on each consecutive day, as an average of all three values, and as changes from baseline; all P > 0.05). The population was subsequently divided into four profiles based on eGFR (preserved vs. impaired; cutoff of 60 mL/min/1.73 m2 ) and UNa+ (sodium excreter vs. non-excreter; cutoff of 60 mmol/L). At day 1, there were 70 (31.9%) patients classified as preserved eGFR/sodium excreter, 37 (16.8%) as impaired eGFR/sodium non-excreter, 72 (32.9%) as impaired eGFR/sodium excreter, and 40 (18%) as preserved eGFR/sodium non-excreter. Both sodium non-excreter profiles were associated with an increased risk of in-hospital heart failure worsening [odds ratio (OR) 2.8, 95% confidence interval (CI) 1.3-6.4], inotrope use (OR 2.6, 95% CI 1.1-6.7) and rehospitalization due to AHF (OR 3.2, 95% CI 1.6-6.2; all P < 0.05). The preserved eGFR/sodium non-excreter profile was associated with highest 1-year mortality (52.5%) and remained an independent prognosticator after adjustment for other prognosticators (hazard ratio 2.9, 95% CI 1.7-5.2; P < 0.0005). CONCLUSIONS: In AHF, values of spot UNa+ and eGFR are not interrelated. Concomitant assessment of eGFR and spot UNa+ may be useful for better clinical and therapeutic profiling of patients.
