[Excretion of uric acid in cardiac decompensation].

The role of hyperuricemia is confirmed, in literature, as a risk factor in ischemic heart disease and in the development of atherosclerotic complications. The problem of uric acid concentration in serum is still not elucidated as well as the role of the eventual hyperuricemia as a risk factor and its excretion from the kidneys of patients with heart diseases in a decompensation stage. Thirty five patients with different heart diseases in various decompensation stages were observed. In all patients, the uric acid concentration in serum were studied as well as the clearance of uric acid, reabsorption percentage in tubules and glomerular filtration according to the clearance of endogenous creatinine. The results obtained revealed that hyperuricemia (over 7 mg%) is found in a great number of the patients (40%) with heart decompensation. The hyperuricemia established resulted primarily from the reduced filtration of glomeruli. In some of the cases, an increased reabsorption of uric acid in tubules was found. In other, single cases, data exist about uric acid secretion in tubules. The problem of heart patients treatment in decompensation stage with the presence of hyperuricemia is discussed. In those cases, very likely, prophylactic measures should be undertaken due to the fact that hyperuricemia is a factor, secondarily leading to atherosclerotic heart alterations.
