摘要(Abstract)：

目的:利用定量组织速度成像技术(QTVI)探讨原发性高血压患者心室舒张功能减退的规律。方法:选择原发性高血压患者151例作为实验组,健康体检者40例作为对照组,检测舒张早期(Em)及舒张晚期(Am)左右房室瓣环室间隔处、侧壁处组织速度峰值,并计算Em/Am比值。结果:实验组心室舒张功能减退发生率高于对照组,随血压级别升高及病程进展室间隔、左心室游离壁舒张功能减退发生率逐渐增高,病程1~4.9年患者单独右心室舒张功能减退发生率高于病程5~9.9年及10~15年患者。结论:原发性高血压患者随病程、级别增加,心脏局部舒张功能减退呈现由右室向室间隔及左室发展趋势,右心室舒张功能减退早于左心室。
Objective :To investigate the rule of right ventricular diastolic function subsiding of essential hypertension by applying quantitative tissue velocity imaging technique( QTVI). Methods:A total of 151 patients with essential hypertension were assigned as experiment group and 40 healthy people as control group.Detecting the late diastolic(Am) and early diastolic(Em) of tissue velocity peaks: septum and sidewall of right and left atrioventricular annulus, and then calculating Em/Am ratio. Results :The incidence of right ventricular diastolic function subsiding in experiment group was higher than control group;the incidence of diastolic dysfunction of interventricular septum,left ventricular free wall gradually increased with the increase of blood pressure level and disease progression;single right heart diastolic dysfunction incidence of 1 to 4.9 years disease course group was higher than that of 5—9.9 years and 10~15 years disease course groups. Conclusions: With the increase of the course and severity of the disease in hypertensive patients, cardiac diastolic dysfunction exhibits by right ventricular developing to interventricular septum and left ventricular, the changes of right ventricular are earlier than left ventricular ones.
