摘要
目的应用定量组织多普勒速度成像(QTVI)技术研究1级高血压病(轻度)患者左室舒张功能的改变。方法用QTVI技术对50例正常人和68例1级高血压病患者左心室12个节段心肌舒张早期峰值速度(E波)、舒张晚期峰值速度(A波)及E/A比值进行分析。结果1级高血压患者与正常人相比较心肌舒张早期峰值速度(E波)降低,舒张晚期峰值速度(A波)增高,E/A比值降低,其中47.2%的节段E/A<1,以室间隔、前壁和后壁多见。结论1级高血压患者存在心肌舒张功能异常。
Objective To inverstigate the variation of diastolic function of left ventricle in patients with hypertension grade Ⅰ derived from quantitative tissue velocity imagine（QTVI）. Methods ro 50 healthy subjects and 68 hypertension grade Ⅰ patientsg peak early diastolic E wave, A wave and the E/A ratios at 12 different sites on the left ventricle myocardium were eualuated by quantitative tissue velocity imagine（QTVI）. Results Compared with the healthy subjects , peak early diastolic is reduction especially a significant reduction of E and increment of A, reduction of E/A ratios, and 47.2% of the total sites of left vetricle in hypertension grade Ⅰ showed that the E/A ratios were less than 1, especially in the sites of interventricular septum,anterior and posterior wall. Conclusion The diastolic function abnormality of left ventricular myocardiam can be found in patients with hypertension grade Ⅰ.
