Brief Summary:
The purpose of this study is to determine whether glucocorticoids have potent diuretic effects in patients with congestive heart failure.

Condition or disease Intervention/treatment Phase
Heart Failure, Congestive Drug: dexamethasone Phase 1

Detailed Description:
Glucocorticoids are known to have pronounced physiological effects in the kidney. Conventional teaching dictates that it should be used with caution in patients with congestive heart failure due to its fluid and sodium retention effects. Surprisingly, despite the widespread prevalence of this belief within the medical community, there are few data to support it. In fact, several small animal studies have documented its striking diuretic effects due to increased renal plasma flow and glomerular filtration rate without changes in the glomerular filtration fraction. We design this study to determine whether glucocorticoids have a potent diuretic effect in patients with heart failure.
