摘　　要：目的　探讨心导纳微分环 (CADL)检测在陈旧性心肌梗死 (OMI)患者心功能评价中的作用。方法　对 38例NYHA心功能Ⅰ级、Ⅱ级 (A组 )和 2 2例心功能Ⅲ级、Ⅳ级(B组 )的OMI患者及 4 0例健康成年人进行CADL检测 ,同时进行超声心动图 (UCG)检查。结果　A、B组分别与对照组比较收缩功能指标 ,A组Ⅰ +Ⅱ %、EF减小 (P <0 0 5 ) ,B组Ⅰ +Ⅱ %、EF减小 (P <0 0 1) ,PEP/LVET、LVESD增大 (P<0 0 5 ) ;A、B两组间比较 ,PEP/LVET增大、Ⅰ +Ⅱ %减小(P <0 0 1)。舒张功能指标A组与对照组比较 ,无统计学差异 ;B组与对照组比较 ,Ⅲ /Ⅰ +Ⅱ增大、E/A比值减小 (P <0 0 1) ;A、B两组间比较 ,Ⅲ /Ⅰ +Ⅱ增大 (P <0 0 1) ,E/A比值减小 (P >0 0 5 )。反映心室收缩协调性方面 ,病例组Ⅰ相环体切迹总阳性率 73 3% ,UCG室壁节段性运动异常的阳性率 5 3% ,两种方法的阳性率具有统计学差异 (P <0 0 5 )。结论　CADL可反映OMI患者的心功能状态 ,是一种简便、无创的评价心功能的检测方法。Objectives To investigate the role of cardiac admittance differential loop (CADL) in evaluating cardiac function of the patients with old myocardial infarction (OMI). Methods Sixty patients with definite diagnosis of OMI were divided into group A( n =38,including NYHA class Ⅰ and Ⅱ) and group B( n =22,including NYHA class Ⅲ and Ⅳ).40 healthy adults were taken as the control group. All of them undertook both CADL examination and ultrasonic cardiogram(UCG) examination. Results Compared indexes of systolic function with the control group separately, it was found that Ⅰ+Ⅱ% and EF of group A decreased ( P <0.05);Ⅰ+Ⅱ%,EF decreased( P <0.01) and PEP/LVET, LVESD increased ( P <0.05) in group B. Compared with group A, PEP/LVET increased and Ⅰ+Ⅱ% decreased ( P <0.01) in group B. The results of comparison of indexes of diastolic function among the three groups showed that there was no difference between the control group and group A, Ⅲ/Ⅰ+Ⅱ increased and E/A decreased ( P <0.01) in group B compared with the control group. Ⅲ/Ⅰ+Ⅱ of group B increased significantly compared with group A. The percentage of notch in phase Ⅰ of CADL was 73.3% and the percentage of abnormal segmental movement of ventricular wall was 53% in UCG examination.Conclusions CADL may reflect cardiac function of the patients with OMI. This method is convenient and noninvasive.
