慢性肾功能衰肾衰患者常伴有心功能受损，临床表现多种多样，可为充血性心衰，心律失常，透析有关的低血压，甚至死亡[1]。不同的左室结构对其功能影响亦不同，因此，研究慢性肾衰患者左室结构和功能的改变，对左室状态作出可靠评价，对估计预后具有较重要的意义。对象与方法一 Chronic renal failure patients with renal failure often accompanied by impaired cardiac function, a variety of clinical manifestations, congestive heart failure, arrhythmia, dialysis-related hypotension, and even death [1]. Different left ventricular structure of its function is also different, therefore, to study changes in left ventricular structure and function of patients with chronic renal failure, to make a reliable assessment of left ventricular status, the prognosis of the more important.
