Abstract
Background:The mechanism underlying serum creatinine (SCr) fluctuations in heart failure (HF) patients remains unclear. This study examined mediators of SCr fluctuations under diuretic treatment in HF patients. Methods and Results:Data from 26 HF patients were analyzed. Clinical tests included measurement of peripheral blood, blood urea nitrogen, SCr, serum and urinary electrolytes, B-type natriuretic peptide (BNP), and plasma neurohormones. Among the 26 patients recovering from worsening HF, changes in SCr were negatively correlated with changes in serum Cl, and positively correlated with changes in plasma arginine vasopressin (AVP). According to the median change in SCr, patients were divided into high (range 0.16–0.79 mg/dL; n=13) and low (range −0.35 to 0.14 mg/dL; n=13) change groups. Plasma AVP concentrations after treatment decreased in the low SCr change group and increased in the high SCr change group (−1.28±2.8 vs. 2.14±4.4 pg/mL, respectively; P=0.027). In both groups, there was no change in plasma volume, plasma BNP and norepinephrine concentrations decreased, and plasma renin activity increased after treatment. Multivariate logistic regression analysis showed a tendency towards an independent association between an increase in SCr and an increase or no change in the plasma AVP after decongestion (odds ratio 4.44; 95% confidence interval 0.81–24.3; P=0.086). Conclusions:Plasma AVP appears to be a physiologically important mediator of SCr fluctuations under decongestion treatment in HF patients.Keywords
