心肌应变与应变率在心血管疾病中的应用

近年来我国心血管疾病的发病率以及死亡率逐年增多,现已成为我国最高致死性疾病之一,对此类患者局部心肌功能的评价对其疾病的诊断、治疗及预后具有重要意义,因此在临床工作中,迫切需要一个能对局部心肌功能做出客观、定量评价的技术。心肌应变(Strain,S)及应变率(StrainSRate,SR)可以测量局部心肌组织发生的极小形变,从而更加准确的评价局部心肌功能及室壁运动。本文将就近年来心肌应变与应变率在心血管疾病中的应用情况进行综述。

Application of myocardial strain and strain rate in cardiovascular diseases

Now days, cardiovascular disease (CVD) remains one of the leading cause of death in China, its morbidity and mortality is developing year by year. The evaluationSof regional cardiacSfunction (RCF)SinSpatientsSwithSCVD is of great importance for its diagnosis, treatment and prognosis. Strategy to objectively and quantitatively assess the regional cardiac function is critical important. Strain and strain rate (SR) of myocardium can measure tiny deformation of regional myocardium ,offering a more accurate evaluation of RCF and ventricular wall motion. In this review, we summarize the application of strain and SR in cardiovascular diseases in recent years.
