摘　　要：心血管疾病是常见的严重威胁人类健康的疾病,在各种疾病导致的死亡中居于首位。研究表明许多心血管疾病即使早期没有出现明显的临床症状,心脏舒张功能也已经发生损害。从早期预防、临床诊断及后期干预治疗的角度上看,尽早地了解患者心脏舒张功能的变化具有十分积极的临床意义。目前临床上常用超声技术无创评价心脏舒张功能,能够达到早期发现心脏舒张功能变化的目的,对疾病的早期诊断、疗效评估及预后有重要的价值。通过回顾国内外相关文献,本文就超声心动图技术中常用的脉冲多普勒、彩色M型超声心动图、组织多普勒、实时三维超声心动图、Tei指数及二维斑点追踪技术等方法评价心脏舒张功能的研究现状进行综述。其中二维斑点追踪技术作为一项新技术,在评价左室舒张功能方面得到了临床广泛的研究及应用,其不受角度依赖的特点,使其较其他方法更简便、可行性及准确性更高。另外同样分析了超声心动图技术中评价心脏舒张功能常用方法的优点及不足之处。总之,评价心脏舒张功能的超声技术会随着科技水平的提高越来越先进,在未来的医学影像学乃至整个超声医学领域中,都发挥着其不可替代的作用。Cardiovascular disease is a common disease that seriously threatens human health,and occupies the first place in the death caused by various diseases.Studies have shown that cardiac diastolic function has been impaired even if there are no obvious clinical symptoms in the early stage of many cardiovascular diseases.From the view of early prevention,clinical diagnosis and late intervention treatment,it is of positive clinical significance to understand the changes of cardiac diastolic function as early as possible.At present,echocardiography is commonly used in clinical non-invasive evaluation of cardiac diastolic function,which can achieve the purpose of early detection of cardiac diastolic function,and has important value for early diagnosis,curative effect evaluation and prognosis of the disease.By reviewing the related literature at home and abroad,this paper reviews the research status of pulsed Doppler,color M-mode echocardiography,tissue Doppler,Real-time threedimensional echocardiography,Tei index and Two-dimensional speckle tracking technique commonly used in echocardiography to evaluate cardiac diastolic function.As a new technique,two-dimensional speckle tracking technique has been widely studied and applied in the evaluation of left ventricular diastolic function.Its independent characteristic makes it simpler,more feasible and more accurate than other methods.In addition,the advantages and disadvantages of common methods for evaluating cardiac diastolic function in echocardiography were also analyzed.In conclusion,ultrasonic technology for evaluating cardiac diastolic function will become more and more advanced with the improvement of science and technology,and will play an irreplaceable role in medical imaging and even the whole field of ultrasound medicine in the future.
