RESUMO
AIM: To analyse relationships between left ventricular myocardium mass (LVMM) and imbalance of uric acid metabolism in patients with arterial hypertension (AH). MATERIAL AND METHODS: Body mass index, waist/hip circumference index, levels of uric acid in the blood and urine, urinary excretion of albumin, LVMM were estimated in 106 patients with mild and moderate AH (70 males and 36 females, mean age 51 +/- 8.5 years). RESULTS: Hypertensive patients with and without metabolic imbalance of uric acid differ significantly by LVMM index. The latter was higher in metabolic imbalance of uric acid, being the highest if this imbalance combined with microalbuminuria. CONCLUSION: Imbalance of uric acid metabolism in AH patients may indicate affection of both the kidneys and the heart.

AIM: To detect urate renal affection and correlations between purine metabolism, hyperinsulinemia, obesity, dyslipidemia in patients with arterial hypertension (AH). MATERIALS AND METHODS: 78 patients with mild, moderate and severe hypertension have undergone 24-h monitoring of arterial pressure and microalbuminuria test. RESULTS: Hyperuricemia was diagnosed in 21 of 78, hyperuricosuria in 27 patients. 13 patients had combination of hyperinsulinemia with obesity, dyslipidemia, arterial hypertension. Renal symptoms occurred in almost half of the patients with hyperuricemia. Disturbed 24-h rhythm and variability of arterial pressure were encountered more frequently in patients with hyperuricemia and hyperinsulinemia than in patients with normal purin metabolism and no other metabolic shifts. CONCLUSION: Renal abnormalities were found more frequently in hypertensive patients with hyperuricemia and those free of urate disturbances and metabolic changes. A positive correlation exists between body mass index and insulinemia (r = 0.58, p < 0.01), body mass index and uricemia (r = 0.37, p < 0.01), insulinemia and uricemia (r = 0.32, p < 0.01).

Body mass index (BMI) and waist/thigh circumference (WTC) were estimated in 104 patients with mild and moderate arterial hypertension (AH) lasting for 8.4 +/- 3.2 years (63 men, 41 women, mean age 50.2(+)-9.6 years). Blood concentration of uric acid was tested with enzymes (Boehringer Mannheim kits). Only 5 of 104 examinees had BMI under 25. The majority of the patients (79%) had high WTC. Hyperuricemia was detected in 32 of 104 patients. Uric acid level in the blood correlates (r = 0.43) with WTC but not with BMI.
