摘要
目的:探讨高血压病患者动态血压与左心室舒张功能的关系。方法:应用无创动态血压监测系统及彩色多普勒超声心动描记技术对76例老年高血压病患者(高血压组)和20例老年健康体检志愿者(对照组)进行检测,并对检测结果进行分析。结果:①高血压组患者发现有收缩功能不全者11例,占14·5%;舒张功能下降者41例,占53·9%;②根据二尖瓣血流A峰速度(A)与E峰速度(E)的大小分组,A>E组患者的白天、夜间及24h平均收缩压均高于A<E组(P<0·05),具有统计学意义;③经多元回归分析,发现A/E值与年龄、24h平均收缩压(SBP)呈正相关,回归方程:A/E=-2·308+0·02504×年龄+0·01546×24hSBP,确定系数R2=0·66,而与各时段平均舒张压无关。结论:老年高血压病患者左心室舒张功能不全的指标A/E比值与年龄及平均收缩压水平呈正相关。
Objective:To investigate the relation between 24-hour blood pressure(BP) and its different phase with left ventricular diastolic function in the patients with essential hypertension. Methods: 76 elderly patients with essential hypertension and 20 healthy senior citizens were studied by Ambulatory BP Recording and Doppler Echocardiography. Results: ① 11 patients , accounting for 14.5% ,in this study were suffered from systolic dysfunction. Impaired diastolic dysfunction was found in 41 patients ,accounting for 53.9%.② In group A〉E , 24-hour average systolic blood pressure (SBP) and night-time SBP and daytime SBP were higher than those of the group A〈E ( P〈0.05 ); ③ In a multivariate model, only age ( β=0. 02504,P= 0. 003 ) was correlated positively to the ratio A/E in the senior citizens. Conclusion: Left ventricular diastolic function is positively related to 24-hour SBP and age in the elderly patients with essential hypertension.
