Official title

The Use of Tolvaptan to Prevent Renal Dysfunction in High Risk Patients With Acute Decompensated Heart Failure-Pilot Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

It is well known that the use of loop diuretics in acute setting may decrease glomerular filtration rate (GFR) and increase serum creatinine leading to renal dysfunction. Loop diuretic induced elevation in serum creatinine can lead to increase in length of hospital stay and possibly morbidity. Previous studies have suggested that tolvaptan unlike aggressive loop diuretic therapy may not activate neurohormonal system nor decrease renal blood flow. These properties may make tolvaptan a useful addition to diuretic therapy to prevent renal dysfunction in high-risk patients. Therefore the primary objective of this study is to determine if the use of tolvaptan in combination with diuretic therapy may prevent development of renal dysfunction in high risk patients with heart failure. Hypothesis: Administration of tolvaptan in combination with continuous loop diuretic therapy in acutely decompensated heart failure patients at high risk for developing diuretic induced renal dysfunction will have a lower proportion of patients increasing their serum creatinine \> 0.3 mg/dL within a 96 hour time frame as compared to patients just receiving standard of care continuous infusion diuretic.
