Arterial hypertension associated with hyperuricemia: features of heart damage

Abstract

OBJECTIVE: The aim is the analysis of hyperuricemia influence on the heart features in patients with arterial hypertension. PATIENTS AND METHODS: Materials and methods: We include 75 patients with arterial hypertension which were divided in two groups according to the level of uric acid in the blood, 30 practically healthy people. Patients from the I group (n = 40) had arterial hypertension and coexistent hyperuricemia; ІІ (n = 35) - arterial hypertension. Left ventricular mass index was determined for left ventricular hypertrophy confirmation. We used clinical, anthropometric, biochemical, instrumental, statistical method. Serum uric acid level was observed by the reaction with uricase. Left ventricular mass index was calculated as left ventricular mass to body surface area ratio. The results were analyzed statistically by SPSS 21 and Graphpad. RESULTS: Results: Left ventricular mass index was significantly higher (р = 0,0498) in patients from the І group (109,7 ± 3,21) g/m2 comparable with the ІІ (97,6 ± 5,35) g/m2 and increased in proportion to the biggest level of uric acid (r = 0,31; p = 0,04) in patients with arterial hypertension and hyperuricemia. CONCLUSION: Conclusions: Concentric and excentric left ventricular hypertrophy, increased left ventricular mass index proportionally to uric acid levels (r = 0,31; p = 0,04) is the confirmation of important role of hyperuricemia in the left ventricular hypertrophy development in patients with arterial hypertension.
