摘　　要：目的:采用多个超声心动图参数综合评价高血压患者左心室舒张功能。方法:随机入选原发性高血压患者40例,在常规超声心动图初步评价左心室舒张功能的基础上进行彩色M型和多普勒组织成像检查,根据测定的参数E／A比值、Vp、E／Vp比值和E／Em比值等对舒张功能进行分层评估。结果:将具备上述4项指标至少2项以上定义为舒张功能异常,舒张功能异常的例数为16例;如仅以目前临床最常用的E／A比值作为评价标准,则漏诊6例、误诊2例。舒张功能异常者左心房增大更明显。结论:综合运用多种超声心动图参数可以更加全面、准确评价高血压患者左心室舒张功能,有利于疾病的合理治疗。Objective: The aim of this study was to evaluate the left ventricular diastolic function of left ventricle by using echocar-diographic parameters comprehensively .Methods: The study population consists of 40 patients with hypertension. After assessing left ventricular diastolic function by traditional echocardiography, color M - mode and Doppler tissue imaging(DTI)was performed and several parameters of LV filling and relaxation were used in every patient for further stratifying risk of diastolic dysfunction. Results: If at least two of four indexes including E/ A < 0.75 or > 1.5, Vp<55, E/ Vp> 1.5 or E/ Em<8 exists, diastolic dysfunction was defined .The total patients of diastolic dysfunction was 16,8 patients would be considered diastolic dysfunction in error evaluated by only the index of E/Aratio.Leftatrias were bigger significantly in the group of patients with diastolic dysfunction.Conclusion:To evaluate accurate-ly the diastolic function of the left ventricle, using several parameters of echocardiography comprehensively is needed and reasonable.
