To examine whether hawthorn (Crataegus Special Extract WS 1442 {CSE}) inhibits progression in heart failure (HF) patients.


We performed a retrospective analysis of data from the HERB CHF study in which patients with mild to moderate HF were randomised to either CSE 900 mg or placebo for 6 months. The primary outcome was time to progression of HF (HF death, hospitalisation, or sustained increase in diuretics) as assessed by log-rank tests and by Cox modelling.


Progression of HF occurred in 46.6% of the CSE and 43.3% of the placebo groups (OR 1.14, 95% CI=0.56, 2.35: p=0.86). Patients receiving CSE were 3.9 times (95% CI=1.1-13.7: p=0.035) more likely to experience HF progression at baseline. In adjusted analysis, the risk of having early HF progression in the CSE group increased to 6.4 (95% CI=1.5, 26.5: p=0.011). In patients with LVEF< or =35%, those taking CSE were at significantly greater risk (3.2, 95% CI=1.3, 8.3: p=0.02) than the placebo group.


CSE does not reduce heart failure progression in patients who have HF. CSE appears to increase the early risk of HF progression.
