Background: The reduced diuretic response (DR) has been shown to be associated with poor clinical outcome in patients with acute decompensated heart failure (ADHF). In addition, hypoalbuminemia, which is related to DR, has been also reported to predict poor prognosis in ADHF patients. However, there is no information available on the impact of albumin level on the prognostic value of DR in patients with ADHF.

Methods: We prospectively studied 296 consecutive patients who were admitted for ADHF and survived to discharge. The patients were divided into 2 groups according to the presence or absence of hypoalbuminemia at the admission, defined as the serum level of albumin at admission <3.5g/dl, and DR was defined as weight loss per 40mg intravenous dose and 80mg oral dose of furosemide up to day 4. The endpoint was a composite of all-cause mortality and unplanned hospitalization for worsening heart failure.

Results: There were 144 patients with hypoalbuminemia and 152 patients without hypoalbuminemia. During a mean follow-up period of 2.2±1.5 years, 88 patients with hypoalbuminemia and 53 patients without hypoalbuminemia reached the endpoint. In group with hypoalbuminemia, DR was significantly smaller in patients with than without the endpoint (0.85 [0.50–1.50] vs 1.60 [0.76–2.70] kg/40mg furosemide, p=0.003), while there was no significant difference in DR between them in group without hypoalbuminemia (1.17 [0.59–1.66] vs 1.07 [0.75–1.88] kg/40mg furosemide, p=0.381). At multivariate Cox analysis, in group with hypoalbuminemia, DR was significantly associated with the endpoint, independently of age, left ventricular ejection fraction, and serum creatinine and plasma BNP levels. On the other hand, in group without hypoalbuminemia, DR showed no significant association with the endpoint at univariate Cox analysis. Kaplan-Meier analysis showed that patients with poor DR (≤1.08 kg/40mg furosemide: median value) had a significantly higher risk of the endpoint in group with hypoalbuminemia, but not in group without hypoalbuminemia (Figure).

Conclusion: Our results suggested that prognostic value of DR in ADHF patients is affected by the presence or absence of hypoalbuminemia.
