Abstract
The aim of this work was to study the availability of vitamin D in the population of free living elderly people in St. Petersburg and its relationship with laboratory indicators of the risk of cardiovascular complications. In winter were surveyed 209 volunteers who did not take vitamin D during the previous 6 months, with 152 women and 57 men aged 71 to 91 years. In all the examined patients the concentration of D(OH) in serum was below 30 ng/ml (analyzer and reagents «Architect i1000SR, Abbott»). No significant mutual effects were found between level 25(OH)D and lipid spectrum, hemoglobin A1C, testosterone, ultra-sensitive C-reactive protein. The close relationship between vitamin D(OH) concentration and brain natriuretic peptide (BNP) levels was characterized by rs=0.187 (p=0.007). In older people with severe vitamin deficiency (less than 10 ng/ml), the risk of elevated BNP levels was 2.6 times higher than in those with reduced vitamin levels (20-30 ng/ml).
