应用彩色多普勒超声（ＵＣＧ）动态检查５０例白血病患者治疗前、化疗获完全缓解（ＣＲ）后的心脏解剖结构及功能变化，并与３０例健康人（对照组）进行比较。结果显示，观察组均有不同程度的室壁回声改变，瓣膜、乳头肌增厚，回声增强，心包受损、心包积液，左室舒张功能减退；ＣＲ后多数恢复正常，与治疗前比较差异显著（Ｐ＜０．０１）。提示白血病患者心脏存在较严重损害，ＣＲ后仍存在一定的心脏损害，其是影响预后的重要因素。
Fifty patients with leukemia were examined dynamically by dynamic color Doppler ultrasonography (UCG) before and after complete remission (CR). The changes of cardiac anatomy and function were compared with those of 30 healthy people (control group). The results showed that the observation group had varying degrees of wall echo changes, valve, papillary muscle thickening, echo enhancement, pericardial damage, pericardial effusion, left ventricular diastolic dysfunction; CR most of the return to normal, compared with before treatment Significant (P <0.01). Prompt leukemia patients with more serious heart damage, CR still exists after a certain heart damage, which is an important factor affecting the prognosis.
