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: To evaluate the left ventricular diastolic function in hypertensive patients by using multiple echocardiographic parameters. Methods: Forty patients with essential hypertension were enrolled in this study. Color M-mode and Doppler tissue imaging were performed on the basis of preliminary echocardiographic evaluation of left ventricular diastolic function. According to the measured parameters E / A ratio, Vp, E / Vp ratio and E / Em ratio stratified assessment of diastolic function. Results: At least two of the above four indexes were defined as diastolic dysfunction and diastolic dysfunction in 16 cases. If only the most commonly used clinical E / A ratio was used as the evaluation standard, 6 cases were missed and misdiagnosed 2 cases. Abnormal left ventricular diastolic function increased more pronounced. Conclusion: The comprehensive use of multiple echocardiographic parameters can be more comprehensive and accurate evaluation of left ventricular diastolic function in hypertensive patients, is conducive to the rational treatment of the disease.
