One hundred and sixty patients with IHD were examined--73 males and 87 females, average age for males--58.58 +/- 12.69 and for females--59.65 +/- 7.76. Elevated levels of uric acid were found in 51.5 per cent. The correlation analysis showed a positive correlation dependence between total fats and uric acid, between cholesterol and uric acid as well as between total protein and uric acid and reverse dependence between uric acid and alpha 2-globulines, beta and gamma globuline fractions. The results from the investigations carried out provided grounds to admit hyperuricemia to be one of the risk factors of IHD.
