Abstract
Objective: To evaluate the impact of two original compositions of polyphenols-containing dietary supplement on lipid profile and level of C-reactive protein (CRP) in patients with angiographycally verified coronary artery disease (CAD). Design and methods: 167 patients were selected during their scheduled post-event elective bicycle stress-test examination. All patients received standard CAD therapy and permanent statin therapy and had elevated total cholesterol (TC > 5.0 mmol/L) and/or CRP (>3.5 mg/L) levels. The study consisted of 2 days of polyphenol depletion followed by a 12-week supplementation period in a randomized, blinded, placebo-uncontrolled parallel design. Two different compositions SILVA 1 (Quercetine, linseed oil and Resveratrol), and SILVA 2 (Quercetine, linseed oil and Pycnogenol) were tested. Results: All parameters changed compared baseline and 1 and 3 months in both groups. CRP decreased from 2.48 ± 1.62 mg/L at baseline to 1.97 ± 1.15 mg/L, high density cholesterol (HDL-C) increased from 1.18 ± 0.31 to 1.38 ± 0.34 mmol/L, also decrease of triglycerides (TG) from 1.5 to 1.29 mmol/L after 3 months treatment in SILVA I group was statistically significant (p < 0.001). Changes of parameters between baseline and 1 or 3 months in SILVA II group were not statistically significant. Hovewer, decrease of CRP (from 2.6 ± 1.28 to 2.41 ± 1.68), decrease of low density cholesterol (LDL-C from 2.95 ± 1.2 to 2.88 ± 1.21), increase of HDL-C (from 1.25 ± 0.22 to 1.34 ± 0.23), decrease of TC (from 5.2 ± 1.3 to 5.1 ± 1.28) and decrease of TG (from 1.4 ± 0.41 to 1.3 ± 0.38) can be counted as tendency of changes. Conclusion: This study reveals the superiority of treatment with statins in combination with composition containing Resveratrol for correction of lipid profile and inflamation marker CRP of patients with CAD
