【摘要】：目的探讨心脏磁共振(CMR)特征追踪(CMR-FT)技术定量评价肥厚型心肌病(HCM)患者心肌形变的价值。方法对16例HCM患者(HCM组)及18名健康志愿者(正常对照组)采用CMR-FT技术行CMR检查。比较两组间左心室舒张末期容积(LVEDV)、收缩末期容积(LVESV)、左心室射血分数(LVEF)、左心室质量(LVMASS)及左心室心肌整体径向应变(RS)、环向应变(CS)的差异。并分析HCM患者各节段室壁厚度与节段性RS、CS的相关性及整体RS、CS与LVEDV、LVESV、LVEF、LVMASS间的相关性。结果HCM组的LVMASS高于正常对照组[(133.74±79.13)g vs(76.87±14.15)g,P=0.01]。两组间LVEDV、LVESV、LVEF差异均无统计学意义(P均0.05)。HCM组心肌整体RS、CS值均明显低于正常对照组[RS:(27.05±13.35)%vs(40.62±4.92)%,P0.01;CS:(-8.68±5.56)%vs(-20.73±1.56)%,P0.01]。HCM患者各节段室壁厚度与节段性RS(r=-0.41,P0.01)、CS(r=0.28,P0.01)间无相关性;心肌整体RS(r=-0.36、-0.41、0.22、-0.36)、CS(r=0.34、0.10、0.22、0.42)与LVEDV、LVESV、LVEF、LVMASS间无相关性(P均0.05)。结论 CMR-FT有助于定量评估HCM患者心肌形变情况。
[Abstract]:Objective to evaluate the value of cardiac magnetic resonance (CMR) characteristic tracing (CMR-FT) in quantitative evaluation of myocardial deformation in patients with hypertrophic cardiomyopathy (HCM). Methods CMR was performed in 16 patients with HCM (HCM group) and 18 healthy volunteers (normal control group) with CMR-FT technique. The left ventricular end-diastolic volume (LVEDV),) end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), left ventricular mass (LVEF),) and global radial strain (RS),) circumferential strain (CS) were compared between the two groups. The correlation between ventricular wall thickness and segmental RSV CS in patients with HCM and the correlation between whole RSV CS and LVMASS of LVESVV LVEFN were analyzed. Results the LVMASS of the HCM group was higher than that of the normal control group [(133.74 卤79.13) g vs (76.87 卤14.15) g P0. 01]. 涓ょ粍闂碙VEDV,LVESV,LVEF宸紓鍧囨棤缁熻瀛︽剰涔，
