摘要
研究探讨了高血压病人左心房结构的改变与年龄、性别、高血压程度、高血压时间和左心室收缩舒、张功能之间的关系。方法：将２４１ 例高血压病人分别按年龄、性别、高血压程度和高血压时间分组，利用心动超声测量病人左心房面积、二尖瓣 Ｅ峰、 Ａ 峰、 Ｅ／ Ａ比值及 Ｅ Ｆ值，与正常组１０６ 例 分别进行统计学比较。结果：高血压病人左心房扩大的发生与年龄密切相关，与血压高度密切相关，与二尖瓣 Ｅ峰降低， Ａ 峰升高， Ｅ／ Ａ比值倒置的发生相一致，即左心房扩大与左心室充盈功能和顺应性密切相关。同时认为高血压病左房结构的改变与性别、高血压病程和左心室射血分数相关不密切。结论：左室充盈功能和顺应性降低是高血压病早期的改变，左心房扩大是高血压心脏病的早期征象。
Aim:The present study is designed to explore the relationship between the left atrium and ages ,sex, BP,duration of hypertension,systolic and diastolic function of the left ventricle in hypertensive patients.\ Methods:Left atrial size ,E peak, A peak, E/A ratio, and EF of ventricular function were evaluated by echocardiography.\ Results:Compared with control group(106 cases),left atrial enlargement was closely related with ages and hypertensive grade. The size of left atrium was associated with decreases in E peak, reversal E/A ratio and increases in A peak. Left atrial enlargement was closely relate to deterioation of filling function and compliance of left ventricle. The changes in left atril construction were not related to sex,hypertensive duration,and EF value.\ Conclusion:Enlargement of left atrium and reduced filling function and compliance in left ventricle may be the early signs of hypertensive heart disease.
