Assessment of the state of the cardiovascular system in young and middle-age military men depending on the level of blood serum uric acid

Abstract

BACKGROUND: The prevalence of asymptomatic hyperuricemia is about 10%. It is a frequent companion of cardiorenometabolic diseases. Hyperuricemia contributes to systemic inflammation, leads to endothelial dysfunction and impaired renal function. An increase in blood pressure occurs due the to the activation of the renin-angiotensin-aldosterno system in hyperurecemia. The level of uric acid more than 360 mol/l in women and more than 420 mol/l in men serves as an unfavorable prognosis factor. Increased attention is needed to monitoring uric acid, especially in those with multiple risk factors for the development of cardiovascular disease.
 AIM: to study clinical, laboratory and instrumental indicators of the cardiovascular system in men with normouricemia and hyperuricemia to improve prevention.
 MATERIALS AND METHODS: The clinic analyzed the case histories of 355 patients aged 30 to 50 years. All examined, depending on the level of blood uric acid, were divided into 4 groups: the 1st group (58 people) 299 mol/l, the 2nd (104 people) 300359 mol/l, the 3rd (104 people) 360419 mol/l and the 4th (89 people) 420 mol/l. Clinical, laboratory and instrumental indicators of cardiovascular system, physical performance and hemodynamic response to physical activity according to bicycle ergometry were studied.
 RESULTS: It has been established that hyperuricemia is associated with an increase in office and daily BP parameters, an increase in heart rate, R wave amplitude in the AVL lead on the ECG, glycemia, lipidemia, SCORE risk, relative left ventricular wall thickness and left atrial size, and left ventricular diastolic function. The total amount of exercise performed, maximum heart rate and exercise tolerance in people with normal uricemia significantly exceed those in patients with hyperuricemia, and the initial heart rate and peak and blood pressure in the recovery period are significantly higher with hyperuricemia, compared with men with normouricemia.
