CK技术评价急性心肌梗死患者存活心肌和住院并发症的关系

Study on the relationship between viable myocardium detected by color kinesis and in-hospital complications in acute myocardial infarction

为探讨存活心肌与急性心肌梗死（AMI）后住院并发症的关系，应用彩色室壁运动分析技术（CK）结合多巴酚丁胺负荷超声心动图试验（DSE）检测24例AMI患者。结果：23例成功地进行了CK－DSE，CK示299个心肌节段中有205个室壁运动正常，74个室壁运动消失，DSE后8例观察到22个运动消失的节段彩色编码标记的运动轨迹增加一级，列为存活心肌组，15例试验后运动消失的节段CK彩色编码无变化，列为无存活心肌组。前组仅3例在住院过程中出现并发症，后组10例出现并发症。后组住院并发症发生率明显高于前组（P＜0．05），而反映心肌梗死面积的CPK峰值在两组中无明显差异（P＞0．05）。表明AMI后存活心肌与住院并发症有一定关系。

In order to invesitigate the relationship between viable myocardium and in-hospitalcomplications, 23 of 24 patients with acute myocardial infarction were successfully studied with color kinesis(CK) combined with dobutamine stress echocardiography. 205/299 segment motion wasnortnal, 74/299 segment motion was disappeared. The patient were divided into two groups. In 8patients (39% ),the color codes of 22 segment with akinesis were augmented one grade after DSEand they were classified as viable myocardium group. Other 15 patients whose akinesis segment didnot improve after DSE were classified as no viable myocardium group. In viable myoca-rdium grouponly 3 patients had complications during hospitalization. But,in no viable myocadium group, 10 patients had complications during hospitalization(P＜0. 05). However, there was no significant difference in the peak value of CPK between the two groups (P＞0. 05 ). Conclusions: The study suggested that the bad long-term prognosis in patients with viable myocardium might be had tight relation with left ventricular remodeling.
