[Work test in acquired heart valve defects]

The physical working capacity to 34 patients with acquired cardiac valvular defects and right catheterization was determined via bicycle ergometer "Zimermann" (GDR). Reverse correlation was established between the physical capacity and pressure 0,93 +/- 0,13 kPa (7,0 +/- 1,0 mm Hg) in right auricle (p less than 0,01), 0,9 +/- 0,27 kPa (6,75 +/- 2,12 mm Hg)--in right auricle (p less than 0,01), 4,18 +/- 1,21 kPa (31,5 +/- 9,02 mm Hg)--in pulmonary artery (p less than 0,05) and 2,66 +/- 0,26 kPa (9,19 +/- 6,76 mm Hg)--in pulmonary capillaries (p less than 0,5). The data from the study coincide with those of the other researchers who established reverse correlation between the physical working capacity and functional class according to New York Cardiological Association. The degree of mitral-valvular stenosisin "pure" or dominating mitral stenosis, degree and duration of cardiac insufficiency, duration of cardiac defect and auricular fibrillation.
