应用脉冲多普勒超声法测定39例较中度高血压病（EH）患者和正常人左室舒张功能各项参数，进行相关性分析，结果显示：EH组PVE变小，PVA增大，PVE／PVA比值缩小，IRT延长，LVmass和LVmI增加，LAD增大，均与对照组相差显著（P＜0．05～0001）。PVE／PVA，IRT和LVmass均与MAP呈相关性（r＝－0.37，0．37，0．41）；LVmass与PVE／PVA，IRT，LAD和LVmI相关性好（r＝－0．41，0．38，0．53，0．96）；且IRT与PVE／PVA呈负相关（r＝－0．43）。研究表明，EH患者早期常出现左室舒张功能异常，测量PVE／PVA及IRT便捷、直观。左室舒张功能受累还常伴有左房内径扩大和LVmI增加。
The parameters of left ventricular diastolic function in 39 patients with moderate hypertension (EH) and normal persons were determined by pulsed-wave Doppler ultrasonography and the correlation analysis was made. The results showed that PVE in EH group was smaller, PVA was increased, PVE / PVA ratio decreased, IRT prolonged, LVmass and LVmI increased, LAD increased, both with the significant difference (P <0.05 ~ 0001). PVE / PVA, IRT and LVmass were correlated with MAP (r = -0.37,0.37,0.41); LVmass was correlated with PVE / PVA, IRT, LAD and LVmI (r = -0.41, 0.38,0.53,0.96); And IRT and PVE / PVA was negatively correlated (r = -0.43). Studies have shown that patients with early EH often appear abnormal left ventricular diastolic function, measurement of PVE / PVA and IRT convenient and intuitive. Diastolic left ventricular involvement is also often accompanied by left atrial enlargement and LVmI increased.
