摘要 【目的】探讨心脏磁共振组织追踪技术(CMR-TT)评估心肌淀粉样变性(CA)患者左心室应变情况及其诊断价值。【方法】选择2017年3月至2020年5月安康市中心医院收治的99例CA患者(观察组),另选取同时间段体检的68例健康志愿者为对照组。采用CMR-TT检测对照组与观察组患者的心功能参数[左心室舒张末期容积指数(LVEDVI)、每博输出量指数(SVI)、心肌质量指数(MMI)、左心室射血分数(LVEF)]、CMR-TT左心室整体应变参数[径向应变(RS)、纵向应变(LS)以及周向应变(CS)],采用Pearson分析左心室的整体应变参数与左心室射血分数(LVEF)的相关性,根据CMR-TT检测的LVEF大小将观察组患者分为A组(LVEF≥50%,n=57)和B组(LVEF<50%,n=42),比较A组与B组心功能参数、CMR-TT左心室整体应变参数,绘制受试者工作特征曲线(ROC曲线),以ROC曲线下面积(AUC)判定整体RS、CS、LS对CA的诊断价值。【结果】观察组LVEDVI、MMI高于对照组,LVEF低于对照组,差异均有统计学意义(P<0.05)。观察组左心室整体RS、CS、LS均低于对照组,差异均有统计学意义(P<0.05)。Pearson分析显示,整体CS、LS、RS与LVEF均呈正相关(r分别为0.641、0.685、0.415,均P<0.05)。B组患者整体RS低于A组,B组患者LVEDVI、MMI、SVI、CS、LS高于A组,差异均有统计学意义(P<0.05)。ROC曲线分析显示,整体RS、CS、LS对CA均具有一定的诊断价值,曲线下面积(AUC)分别为0.787、0.778、0.746(P<0.05)。【结论】CMR-TT可评估CA患者左心室应变特征,且整体应变参数RS、CS、LS对CA具有一定的诊断价值。

Abstract:【Objective】To evaluate the left ventricular strain in patients with cardiac amyloidosis (CA) by cardiac magnetic resonance tissue tracking (CMR-TT) and its diagnostic value. 【Methods】A total of 99 CA patients (observation group) admitted to our hospital from March 2017 to May 2020 were selected, and 68 healthy volunteers who underwent physical examination in the same period were selected as the control group. The cardiac function parameters [left ventricular end-diastolic volume index (LVEDVI), ventricular output index (SVI), myocardial mass index (MMI), left ventricular ejection fraction (LVEF)], and the left ventricular global strain parameters [radial strain (RS), longitudinal strain (LS), and circumferential strain (CS)] of the control group and the observation group were measured by CMR-TT, Pearson was used to analyze the correlation between left ventricular global strain parameters and left ventricular ejection fraction (LVEF). According to the size of LVEF measured by CMR-TT, patients in the observation group were divided into group A ( LVEF≥50%,n=57) and group B (LVEF<50%, n=42). The cardiac function parameters and left ventricular global strain parameters of CMR-TT were compared between group A and group B, and the working characteristic curve (ROC curve) of the subjects was drawn. The overall RS, CS The diagnostic value of LS to CA. 【Results】LVEDVI,SVI and MMI in the observation group were higher than those in the control group, and LVEF was lower than that in the control group, the difference was statistically significant (P<0.05). The overall RS, CS and LS of the left ventricle in the observation group were lower than those in the control group (P<0.05). Pearson analysis showed that the overall CS, LS, RS and LVEF were positively correlated (r=0.641, 0.685, 0.415, all P<0.05). The overall RS, CS and LS of patients in Group B were lower than those in Group A, while LVEDVI and MMI of patients in Group B were higher than those in Group A (P<0.05). The ROC curve analysis showed that the overall RS, CS and LS had certain diagnostic value for CA. The area under the curve (AUC) was 0.787, 0.778 and 0.746 respectively (P<0.05). 【Conclusion】 CMR-TT can evaluate the left ventricular strain characteristics of patients with CA, and the overall strain parameters RS, CS, LS have certain diagnostic value for CA.
