Summary of "Vitamin D and laboratory indicators of cardiovascular risk in the elderly."

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 A1, 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).

Medical and Biotech [MESH] Definitions

A nutritional condition produced by a deficiency of VITAMIN A in the diet, characterized by NIGHT BLINDNESS and other ocular manifestations such as dryness of the conjunctiva and later of the cornea (XEROPHTHALMIA). Vitamin A deficiency is a very common problem worldwide, particularly in developing countries as a consequence of famine or shortages of vitamin A-rich foods. In the United States it is found among the urban poor, the elderly, alcoholics, and patients with malabsorption. (From Cecil Textbook of Medicine, 19th ed, p1179)

A nutritional condition produced by a deficiency of VITAMIN E in the diet, characterized by posterior column and spinocerebellar tract abnormalities, areflexia, ophthalmoplegia, and disturbances of gait, proprioception, and vibration. In premature infants vitamin E deficiency is associated with hemolytic anemia, thrombocytosis, edema, intraventricular hemorrhage, and increasing risk of retrolental fibroplasia and bronchopulmonary dysplasia. An apparent inborn error of vitamin E metabolism, named familial isolated vitamin E deficiency, has recently been identified. (Cecil Textbook of Medicine, 19th ed, p1181)

A specialty concerned with the nursing care of patients suffering from disorders of the CARDIOVASCULAR SYSTEM as well as those identified as at risk for adverse cardiac or vascular events.

A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.

Restoration of functions to the maximum degree possible in a person or persons suffering from a CARDIOVASCULAR DISEASE. It also includes cardiac conditioning and SECONDARY PREVENTION in patients with elevated cardiovascular risk profile.
