Abstract

Recent studies have shown, that chronic flavonoids treatment improves vascular function and cardiovascular remodeling by decreasing superoxide anion production as well as by increasing NO realize from endothelial cells. A progressive decrease in systolic blood pressure and reduction of low-density lipoprotein oxidation (Ox-LDL) has also been reported. However, none of these studies were done in patient with coronary artery disease treated with statins. This was a double-blind, placebo-controlled, parallel trial. Forty-four patients (11 women and 33 men, mean age 66 years) who survived myocardial infraction and have received statin therapy for at least 6 months (80% dose of 40 mg/day simvastatin) were included in the study. The subjects were randomised to receive either 3 x 85 mg/day of chokeberry flavonoid extract (Aronia melanocarpa E) or placebo for a period of 6 weeks. The study extract was a commercially-available (OTC) product of the following declared composition: anthocyans (about 25%), polymeric procyanidines (about 50%) and phenolic acids (about 9%). Compared to placebo (ANOVA and Tukey's test), flavonoids significantly reduced serum 8-isoprostans (p<0.000) and Ox-LDL levels (p<0.000) (by 38 and 29%, respectively), as well as hsCRP (p<0.007) and MCP-1 (p<0.001) levels (by 23 and 29%, respectively). In addition, significant increase in adiponectin (p<0.03) levels and reduction in systolic and diastolic blood pressure by a mean average of 11 and 7.2 mmHg, respectively were found.

CONCLUSION:

In view of the fact that chokeberry flavonoids reduce the severity of inflammation, regardless of statins, they can be used clinically for secondary prevention of ischaemic heart disease.
