Introduction: Newly emerging evidence showed that glucocorticoids could potentiate natriuretic peptides' action by increasing the density of natriuretic peptide receptor A, leading to a potent diuresis and a renal function improvement in patients with acute decompensated heart failure (ADHF). Therefore, glucocorticoid therapy may be used in patients with ADHF.
Methods: One hundred two patients with ADHF were randomized to receive glucocorticoids or standard treatment. Change from baseline in serum creatinine (SCr) at day 7 and cardiovascular death within 30 days were recorded. The study was terminated early because of slow site initiation and patient enrolment.
Results: Glucocorticoid therapy seemed to be well tolerated. There was a remarkable SCr reduction after 7 days treatment. The change from baseline in SCr is -0.14 mg/dL in glucocorticoid group versus -0.02 mg/dL in standard treatment group (P < 0.05). Although sample size is limited, a cardiovascular death reduction at 30 days was observed in glucocorticoid group with odds ratio of 0.26 (3 deaths in glucocorticoid vs. 10 deaths in standard treatment group, P < 0.05). The survival benefit associated with glucocorticoid therapy persisted during the follow-up. Patient-assessed dyspnea and physician-assessed global clinical status were also improved in glucocorticoid group.
Conclusions: Limited data indicate that glucocorticoid therapy may be used safely in patients with ADHF in short term. Glucocorticoid therapy did not cause heart failure deterioration. Further investigations are warranted.
