Abstract

Objective To investigate the hemodynamic changes in uremia patients with heart failure and analysis the causes of these changes.Methods 23 uremia patients with heart failure and 31 without heart failure by using circulation dynamics detection.Results The uremia patients with heart failure of left ventricular end-diastolic pressure and volume,cardiac output, jet resistance, myocardium oxygen comsumption, left ventricular work rate all increases significantly and ejection fraction decreases significantly. Conclusion To uremia patients, the radical cause of heart failure is not the increaed effeative circulatory blood volume but the hyposystole of left ventricular, the decreased compliance of myocardium and the excitement of beta-adrenergic ceptors; Circulation dynamics detection is easy to operate and this test has a good repetition.
