【摘要】：目的运用实时三维超声心动图(RT-3DE)和脉冲多普勒技术评估原发性高血压患者右心室功能及血流动力学的改变。方法采用超声心动图技术对原发性高血压1、2级及3级患者右心室功能参数进行测定,与对照组对比研究。结果与对照组相比,原发性高血压组三尖瓣口舒张早期血流峰值速度(E)、E/舒张晚期血流峰值速度(A)、三尖瓣环游离壁部舒张早期峰值速度(E')、及E'/舒张晚期峰值速度(A')减低,差异有统计学意义(P0.01);E/E'、A'、等容舒张时间(IVRT)及Tei指数增高,差异有统计学意义(P0.01)。A、等容收缩时间(IVCT)及射血时间(ET)在四组间差异有统计学意义(P0.05)。而三尖瓣环游离壁部收缩期峰值速度(S')、三尖瓣环位移(TAPSE)及左右心室容积和射血分数在四组间差异无统计学意义(P0.05)。结论原发性高血压可以在右心室收缩功能损害之前引起右心室舒张功能改变,超声心动图可以早期检测原发性高血压引起的右心室功能损害及其血流动力学改变。
[Abstract]:Objective to evaluate the changes of right ventricular function and hemodynamics in patients with essential hypertension by real-time three-dimensional echocardiography (RT-3 DE) and pulsed Doppler technique.Methods the right ventricular function parameters were measured by echocardiography in patients with grade 1, 2 and 3 of essential hypertension, and compared with those in the control group.Results compared with the control group, the early diastolic peak velocities of the tricuspid orifice and the peak velocities of the early diastolic and late diastolic segments of the tricuspid annulus in the patients with essential hypertension were significantly lower than those in the patients with essential hypertension, and the peak velocities of the free wall of the tricuspid annulus and the peak velocities of the free wall of the tricuspid annulus were also decreased.The difference was statistically significant (P 0.01 / E / E), isovolumic relaxation time (IVT) and Tei index increased, and the difference was statistically significant (P 0.01) and ejection time (et) were significantly different among the four groups (P 0.05).However, there were no significant differences in the peak systolic velocities of the free wall of tricuspid annulus and tricuspid annulus displacements (TAPSEs), left and right ventricular volume and ejection fraction among the four groups (P 0.05).Conclusion essential hypertension can cause right ventricular diastolic function change before right ventricular systolic function damage. Echocardiography can detect right ventricular function damage and hemodynamic changes in early stage.
