Brief summary

Renal Compromise after treatment of decompensated heart failure with diuretics is not uncommon. The purpose of our study is to investigate the relationship between cystatin C and worsening renal function in this setting. Cystatin C is a biomarker produced at a constant rate by all cells that is a sensitive biomarker of renal function.Cystatin C and Plasma amino terminal proB-type natriuretic peptide (NT-proBNP) levels will be obtained at baseline and daily. Our goal is to enroll 100 subjects with an estimated 5 samples per each subject. The time course of changes in cystatin C in relation to serum creatinine levels over time will be plotted. Our hypothesis is that sequential changes in cystatin C levels following initial treatment with diuretic therapy in the setting of acute decompensated heart failure may provide early insight into cardio-renal compromise. Understanding the natural history and time course of the changes in sequential cystatin C levels may facilitate further studies to guide the judicious use of diuretic therapy in acute decompensated heart failure, and to predict the risk of subsequent development of worsening renal function. If serial testing of cystatin C can provide accurate assessment and prediction of worsening renal function, clinical applications of these observations can be evaluated in future prospective studies.
