[Hyperuricemia].

Abstract

The association of elevated serum uric acid (hyperuricemia, gout) with the presence of classical coronary risk factors and coronary artery disease or myocardial infarction has been analysed in many epidemiological studies. In this paper the urid acid metabolism, the factors influancing on this metabolism, the laboratory hyperurycemia criteria and the mode of hyperuricemia treatment are presented. The hyperuricemia and it's collaboration with the other coronary risk factors are analysed as an independent risk factors. Hyperuricemia is described as an increased concentration of uric acid in blood. The urate concentration is elevated when the upper level of arbitrary accepted value is exceeded. That corresponds to the mean value of urate concentration of particular sex and age plus two standard deviations. In most cases of epidemiologic investigations the upper normal range of concentration equals 6 mg/dl for women and 7 mg/dl for men. An increased level of uric acid leads to urate gout (diathesis urica). An increased level of urate in serum is connected with numerous cardiovascular risk factors such as: arterial hypertension, hyperglycemia, diabetes and male sex. But up today, hyperuricemia is not used as independent direct risk factor, so the reduction of uric acid is not obligatory recommended in guidelines for prevention of cardiovascular diseases and stroke.
