[Assessment of central hemodynamics by pump function and sizes of heart chambers in cardiac surgery patients]

In 198 cardiosurgical patients the treadmill test was performed with the noninvasive evaluation of the pump function of the heart and anaerobic threshold. The results were compared with echocardiographic sizes of the left atrium (LA), systolic and diastolic sizes of the left ventricle (CLV and DLV). It was shown that in patients with mitral stenosis the pump function of the heart reliably corresponded to the size of the LA, in mitral regurgitation--O of the DLV, in aortal defects--that of the CLV and DLV. After isolated prosthezing of the heart valves the correlation found was not retained. It was proved that the maximum consumption of O2 did not reliably correlate with LA, CLV and DLV.
