Burst steroid therapy for acute heart failure: The CORTAHF randomized, open-label, pilot trial

AIMS: Burst steroid therapy, effective in acute respiratory diseases, may benefit patients with acute heart failure (AHF) in whom inflammatory activation is associated with adverse outcomes. METHODS AND RESULTS: CORTAHF assessed whether burst steroid therapy reduces inflammation and results in better quality of life and clinical outcomes in AHF. Patients with AHF, N-terminal pro-B-type natriuretic peptide >1500 pg/ml, and high-sensitivity C-reactive protein (hsCRP) >20 mg/L were randomized 1:1 to oral, once daily 40 mg prednisone for 7 days or usual care, without blinding. Patients were followed for 90 days. A total of 101 patients were randomized. At day 7 the primary endpoint, hsCRP decreased in both arms - adjusted geometric mean ratios (GMRs) were 0.30 and 0.40 in the prednisone and usual care arms (ratio of GMRs 0.75, 95% confidence interval [CI] 0.56-1.00, p = 0.0498). The 90-day risk of worsening heart failure (HF), HF readmission or death as reported by the unblinded investigators was significantly lower in the prednisone group (10.4%) than in usual care (30.8%) (hazard ratio 0.31, 95% CI 0.11-0.86, p = 0.016). The EQ-5D visual analogue scale score as reported by the unblinded patients increased more in the prednisone group on day 7 (least squares mean difference 2.57, 95% CI 0.12-5.01 points, p = 0.040). All effects were statistically significant in the pre-specified subgroup with centrally-measured interleukin-6 >13 pg/ml. Adverse events, particularly hyperglycaemia, occurred more in the prednisone group with no difference in infection rate. CONCLUSION: In this small open-label study of patients with AHF, burst steroid therapy was associated with reduced inflammation as measured by hsCRP levels at day 7 (primary endpoint). Secondary endpoints showed improved quality of life at day 7 and reduced 90-day risk of death or worsening HF. Large prospective studies are needed to evaluate these findings.
