摘　　要：目的比较二维应变成像在肥厚型心肌病与高血压性左室肥厚患者中右心室部分与总体应变的评价效果。方法选取100例患者,其中41例高血压性左室肥厚患者为观察组,59例肥厚型心肌病患者为研究组。对比2组患者左心室舒张末期内径、左心室后壁厚度、右心室面积变化率、右心室基底段横径、三尖瓣环组织收缩峰值速度、三尖瓣环收缩期位移、右心室局部和整体纵向应变。结果研究组左心室舒张末期内径显著低于观察组(P<0.05),左心室后壁厚度显著高于观察组(P<0.05);2组右心室面积变化率、三尖瓣环收缩期位移均无显著差异(P>0.05);研究组右室基底段横径、三尖瓣环组织收缩峰值速度均显著低于观察组(P<0.05);研究组右心室部分与整体应变均值均显著高于观察组(P<0.05)。结论相比高血压性左室肥厚患者,二维应变成像应用于肥厚型心肌病患者更易表明其出现右室功能与结构重建的可能性。Objective To compare the effect of two-dimensional strain imaging on evaluation of regional and global strain of right ventricle and hypertensive left ventricular hypertrophy in pa- tients with hypertrophic cardiomyopathy. Methods A total of 100 cases were selected, in which 41 cases with hypertensive left ventrieular hypertrophy were designed as observation group and 59 cases of hypertrophic cardiomyopathy were designed as study group. The left ventricular end diastolic diameter, left ventricular posterior wall thickness, right ventricular fractional area change, right ventricular basal dimension tracing, wall thickness of inter-ventricular septum, tricuspid annular plane systolic execution, right ventricular regional and global longitudinal strain by two-dimensional strain imaging were compared between the two groups. Results The left ventricular end diastolic diameter in the study group was significantly lower than the observation group （ P 〈 0.05 ） , while the left ventricular posterior wall thickness was significantly higher than the observation group （P 〈 0.05 ）. The right ventricular fractional area change and tricuspid annular plane systolic excution showed no significant difference between the two groups （P 〉 0.05 ）. The right ventricular basal dimension tracing and wall thickness of inter-ventricular septum in the study group were significantly lower than the observation group （P 〈 0.05 ）. The regional and global strain in the study group were significantly higher than the observation group （ P 〈 0.05 ）. Conclusion Compared with hypertensive left ventricular hypertrophy, the two-dimensional strain imaging is more helpful for indicating the presence of right ventricular function reconstructing in patients with hypertrophic cardiomyopathy.
