摘要
目的探讨超声心动图在筛查与诊断尿毒症心肌病中的应用价值。方法选择在我院诊治的尿毒症心肌病患者60例为病例组和体检健康者20例为对照组,进行超声心动图检查,测量心脏各腔室内径、心室收缩功能,应用多普勒组织成像技术分析左室舒张功能。结果与对照组比较,病例组的心脏各腔室内径均明显扩大,其中尤以左心增大明显,且室间隔明显增厚(P<0.05);病例组的E峰速度、A峰速度、舒张期等容指数、舒张晚期速度和舒张早期速度等反映心室综合舒张功能均出现明显异常(P<0.05),每搏输出量、左室排出量和左心指数均明显增加(P<0.05),心脏收缩功能下降,但还在正常值范围内。结论超声心动图能够较为直观、准确、无创、动态地观察心脏大小、结构情况,评估心脏功能等,且可早期及时的发现心脏病变,进行追踪及动态观察,为临床筛查与诊断尿毒症心肌病提供可靠的依据。
Objective To explore the value of the application of echocardiogram in diagnosis of uremic myocardiopathy. Methods A certain number of patients with uremic myocardiopathy and treated in our hospital were selected and divided into a patient group（n=60） and a healthy group（n=20）. The two groups received echocardiogram to measure the inner diameter of heart chambers and the contraction function of ventricles. The left ventricular diastolic function was analyzed with Doppler tissue imaging, Results Compared with the control group, the inner diameter of the heart chambers in the patient group was greater, especially that of the left heart, with obvious thicker intcrventricular septum （P 〈 0.05）; the indicators such as E peak velocity, A peak velocity, isovolumic index in diadtolic phase, velocity in late diadtolic phase and velocity in early diadtolic phase got obviously abnormal （P 〈 0.05）; the stroke volume, left ventricle output and left heart index increased greatly （P〈 0.05）： the cardiac systolic function decreased but still within the normal range. Conclusion From echocardiogram, we can observe the size and structure and evaluate the function of the heart in an intuitive, accurate, noninvasive and dynamic manner to diagnose, track and observe cardiac diseases, so as to provide reliable basis for clinical screening and diagnosis of uremic myocardiopathy.
