目的：应用二维斑点追踪技术对 H 型高血压及非 H 型原发性高血压患者心脏机能进行对比性研究。方法 H 型高血压组49例,非 H 型原发性高血压组43例,以及正常对照组60例,分别对观察者的左心室射血分数、左心房内径、左心室内径,16节段室壁的纵向应变,径向应变,环状应变进行测量。结果 H 型高血压组及非 H 型高血压组与对照组纵向应变、径向应变及环状应变差异均有统计学意义(P <0.05),纵向应变的变化较为明显；H 型高血压组与非 H 型高血压组之间比较,部分室壁的纵向应变、径向应变及环状应变差异均有统计学意义(P <0.05)。结论 H 型高血压及非 H 型高血压均可引起心脏收缩功能的减低,且 H 型高血压更为明显,说明高同型半胱氨酸对冠状动脉的损害更为明显。

Objective Two-dimensional speckle tracking imaging was applied in comparative research on the heart function of H and non-H hypertension patients.Methods The study involved 49 cases of H hypertension,43 cases of non-H essential hypertension and 60 normal control cases,their left ventricular ejection fraction,the size of left atria,and left ventricula,longitudinal strain,radial strain and circumferential strain of 1 6 segmental walls were measured.Results H hypertension patients and non-H hypertension patients showed significant difference in longitudinal strain,radial strain and circumferential strain when compared with controlled group,among which the longitudinal strain showed the most obvious change.While compared H hypertension patients with non-H hypertension patients,the longitudinal strain,radial strain and circumferential strain all showed statistical significance(P <0.05). Conclusion H hypertension and non-H hypertension both result in the reduction of heart systolic function,especially among H hypertension patients,which shows the harmfulness of homocysteine to coronary artery is more obviously serious.
