Free adrenaline, noradrenaline and vanilylmandelic acid excretion with 24-hour urine in patients with chronic circulatory failure.

The purpose of this work was to study the excretion of free adrenaline (A), noradrenaline (NA) and vanilylmandelic acid (VMA) in 24-hour urine in patients with chronic circulatory failure. The investigations were carried out in a group of 152 patients (61 women and 91 men) with rheumatic valvular heart disease (61 cases), chronic cor pulmonale syndrome (23), atherosclerotic myocardial degeneration (68). A and NA urinary excretion was normal in cases with grades 1 and 2 of hemodynamic disturbances.
