摘要
目的 探讨尿毒症合并心力衰竭时的血液动力学改变并分析其发生原因。方法 使用血液循环动力学信息检测仪（CD）检测 23例尿毒症合并心力衰竭者及 31例尿毒症无心力衰竭者。结果 充血性心力衰竭组左室舒张末期压力、左室舒张末期容量、心输出量、射血阻抗、心肌耗氧量、左室有效功率均明显增高，射血分数明显降低。结论 CD检测简单方便，重复性好。心力衰竭根本原因左室收缩乏力、顺应性降低、β受体兴奋而不是有效循环血量增加。
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.
