目的:探讨定量组织速度成像(QTVI)在评价原发性高血压(EH)患者局域心肌舒缩功能的临床应用价值。方法:比较EH左室肥厚(LVH)与无左室肥厚(NLVH)患者不同心肌节段的收缩期峰值速度(Vs)、舒张早期峰值速度(Ve)和舒张晚期峰值速度(Va)。结果:LVH及 NLVH组 Vs、Ve值均显著小于正常对照组;LVH组与NLVH组的部分心肌节段Vs、Ve值比较差异有统计学意义(P<0.05)。结论:QTVI能敏感地反映EH不同病期的病理改变,可以作为高血压病程的一个重要参考指标。
Objective: To investigate the clinical value of quantitative tissue velocity imaging (QTVI) in assessing regional myocardial systolic and diastolic function in patients with essential hypertension (EH). Methods: The systolic peak velocity (Vs), early diastolic peak velocity (Ve) and late diastolic peak velocity (Va) were compared between EH patients with left ventricular hypertrophy (LVH) and without left ventricular hypertrophy (NLVH) Results: The values of Vs and Ve in LVH and NLVH groups were significantly lower than those in normal control group. The Vs and Ve values of some myocardial segments in LVH and NLVH groups were significantly different (P <0.05). Conclusion: QTVI can sensitively reflect the pathological changes of EH at different stages, which can be used as an important reference for the course of hypertension.
