左室舒张功能障碍与潜在的高血压的关系研究

目的　通过对舒张功能的测定 ,及时发现潜在的高血压危险因素。方法　应用彩色多普勒超声心动图技术 ,对 34例既往有低血压或偏低血压史 ,以后血压升高者 ,按 WHO 1978年诊断标准仍在正常范围者进行了左室舒张功能测定 ,与 34例 、 期高血压患者及正常人对照分析。结果　前两组舒张功能减低 ,E、A两峰比较无差异并显著高于正常对照组 (P<0 .0 1)。用降压药物治疗后 ,两组舒张功能均改善 (P<0 .0 1)。结论　检测左室舒张功能有助于发现潜在的高血压。

Left ventricular diastolic dysfunction contributing to discovering poten tial danger factor of hypertension

Objective To detect the relationship between latent hypertension and left ventricular diastolic function.Method Left ventricular diastolic function was evaluated by color Doppler echocardiography in Ⅰ group (34 patients,who had a history of hypotension or a declined one,were going to be hypertensive afterwards,but still within the normal extent of WHO standard 1978),Ⅱ group (34 patients with Ⅰ or Ⅱ phase hypertension),and 30 control subjects.Results Left ventricular diastolic function descended in the former two groups,and there was no difference between E and A peaks,but which two peaks were higher remarkably than those in control group (P<0 01).Left ventricular diastolic functions of the two groups all improved after drug treatment.Conclusion The examination of left ventricular diastolic function contributes to finding out latent danger factor of hypertension.
