Is there an effect of folic acid supplementation on the coagulation factors and C-reactive protein concentrations in subjects with atherosclerosis risk factors?
Journal Title: Advances in Hygiene and Experimental Medicine - Year 2012, Vol 66, Issue 0
Abstract
Introduction: Folic acid (FA) may delay the formation of atherosclerotic lesions. Increased plasma levels of von Willebrand factor (VWF) are observed in cardiovascular disease, which leads to higher risk of thrombosis. Fibrinogen (Fb) is a well-documented risk factor of cardiovascular disease. The aim of this study was to analyze the effect of FA supplementation on the Fb, VWF and C-reactive protein (CRP) plasma concentrations in subjects with atherosclerosis risk factors. Material/Methods: The study enrolled 124 Caucasian individuals (60 M, 64 F) with atherosclerosis risk factors – family history of premature ischaemic stroke, arterial hypertension, dyslipidaemia, overweight and obesity, cigarette smoking and low physical activity. The participants were asked to take FA in the low dose of 0.4 mg/24 h for three months. Results: After FA supplementation a significant reduction of the VWF concentrations in females (76.6 vs 72.3%; p=0.028) and in males (75.5 vs 66.9%; p=0.001) was observed. Among women and men with dyslipidaemia concentrations of VWF decreased after FA supplementation (76.8% vs 69.6%; p=0.003 and 76.7% vs 67.8%; p=0.001 respectively). Among females and males with BMI ≥25 kg/m2 concentrations of VWF decreased only in men (77.6% vs 66.5%; p=0.001). In female and male smokers supplementation of FA decreased VWF concentrations (82.5% vs 74.4%; p=0.012 and 76.6% vs 69.5%; p=0.036 respectively). Discussion: The results of our study suggest that there is an effect of FA supplementation on VWF concentrations in subjects with atherosclerosis risk factors.
