Crataegus laevigata is a medicinal plant most commonly used for the treatment of heart failure and psychosomatic disorders. Based on previous experimental findings, this double-blind placebo-controlled study was aimed at finding beneficial effects of C. laevigata on biomarkers of coronary heart disease (CHD). The study included 49 diabetic subjects with chronic CHD who were randomly assigned to the treatment for 6 months with either a micronized flower and leaf preparation of C. laevigata (400 mg three times a day) or a matching placebo. Blood cell count, lipid profile, C-reactive protein, neutrophil elastase (NE) and malondialdehyde were analyzed in plasma at baseline, at one month and six months. The main results were that NE decreased in the C. laevigata group compared to the placebo group. In the C. laevigata group, baseline figures (median and interquartile range) were 35.8 (4.5) and in the placebo group 31 (5.9). At the end of the study, values were 33.2 (4.7) ng/ml and 36.7 (2.2) ng/ml, respectively; p<0.0001. C. laevigata, added to statins, decreased LDL cholesterol (LDL-C) (mean±SD) from 105±28.5 mg/dl at baseline to 92.7±25.1 mg/dl at 6 months (p=0.03), and non-HDL cholesterol from 131±37.5 mg/dl to 119.6±33 mg/dl (p<0.001). Differences between groups did not reach statistical significance at 6 months. No significant changes were observed in the rest of parameters. In conclusion, C. laevigata decreased NE and showed a trend to lower LDL-C compared to placebo as add-on-treatment for diabetic subjects with chronic CHD.
