Brief summary
The purpose of this study is to examine the efficacy of three doses of prednisone, a glucocorticoid, in treatment of patients with symptomatic heart failure.
Detailed description
Heart failure is a leading cause of cardiovascular morbidity and mortality in the world. Most patients with acute symptomatic heart failure are admitted with fluid overload. Intravenous loop diuretics are an essential component of current treatment in such patients. Newly emerging evidence showed that glucocorticoids could potentiate natriuretic peptides' action by upregulating the expression natriuretic peptide receptor A (NPR-A) in the kidney, and produce a potent diuresis. Therefore, the investigators designed this nonblinded, randomized dose comparison study to compare the efficacy of prednisone at 15, 30 and 60 mg/day in patients with in symptomatic heart failure.
Interventions
The patients with symptomatic heart failure are treated with prednisone at dose of 15 mg/day.
