摘要
目的 在左心室心肌致密化不全的患者群体中应用心脏超声诊断技术，讨论该种诊断方法所具备临床价值，并且对左心室心肌致密化不全患者共同表现出的临床特征进行总结。方法 100例符合标准的左心室心肌致密化不全的患者划分为疾病组，同时纳入100例超声心动图结果显示正常的健康人作为健康组，与疾病组进行对比。主要对比两组患者的超声心动图的影像学特征以及左心室的收缩功能指标。结果 患者中最常见的症状主要是心力衰竭、心脏杂音以及心律失常。对比健康组和疾病组患者的左心室收缩功能指标检测值，存在明显差异的三个指标为左心室舒张末期容积、左心室射血分数以及左心室内经缩短率，两个组别患者的监测数据在这三方面存在明显差异（P＜0.05）。结论 将心脏超声诊断技术应用于左心室心肌致密化不全患者的临床诊断中具有一定的价值和意义，结合左心室心肌致密化不全的临床表征和心脏超声诊断技术检查结果可以较准确地把握患者的疾病情况，对于后续的治疗也有重要的参考意义。

Abstract
Objective: To apply cardiac ultrasound diagnostic technology in patients with left ventricular noncompaction, discuss the clinical value of this diagnostic method, and summarize the common clinical characteristics of patients with left ventricular noncompaction. Methods 100 patients with noncompaction of left ventricular myocardium were divided into the disease group, and 100 healthy people with normal echocardiography results were included as the healthy group, and compared with the disease group. The echocardiographic imaging features and left ventricular systolic function indexes of the two groups were mainly compared. Results The most common symptoms in patients were heart failure, heart murmurs, and arrhythmias. Comparing the detection values of left ventricular systolic function indexes between the healthy group and the disease group, the three indexes with significant differences are left ventricular end-diastolic volume, left ventricular ejection fraction, and left ventricular shortening rate. The monitoring of patients in the two groups There were significant differences in the data in these three aspects (P<0.05). Conclusion The application of cardiac ultrasound diagnostic technology in the clinical diagnosis of patients with left ventricular noncompaction has certain value and significance. Combining the clinical manifestations of left ventricular noncompaction and the examination results of cardiac ultrasound diagnostic technology can more accurately grasp the patient's condition. The condition of the disease also has important reference significance for the follow-up treatment.
Key words： left ventricular myocardium noncompaction; clinical manifestations; cardiac ultrasonography diagnosis
