原发性高血压患者动态脉压与左心室肥厚相关性研究

目的探讨原发性高血压患者动态脉压和左心室肥厚之间的相关性。方法根据超声心动图检查结果,按左心室心肌质量指数（LVMI）男〉120g/m^2,女〉115g/m^2,将242例高血压患者分为左心室肥厚组（64例）和非左心室肥厚组（178例）,并进行24h动态血压监测。结果左心室肥厚组的24h平均脉压（PP）、白天脉压（dPP）、夜间脉压（nPP）和非左心室肥厚组相比差异有统计学意义（P〈0.05）。直线相关分析结果显示LVMI与年龄、SBP、PP显著相关（P〈0.01）。多元回归分析结果显示,PP是LVMI的主要影响因素（P〈0.01）。结论PP增大与高血压患者LVH密切相关,是LVMI的主要影响因素。

Relationship between ambulatory pulse pressure and left ventricular hypertrophy in essential hypertension

Objective To explore the relationship between ambulatory pulse pressure and left ventricular hypertension in essential hypertension.Methods Echocardiography were performed, according to their left ventricular mass index (LVMI), 242 patients with essential hypertension were divided into two groups: LVH group (LVMI>120g/m2 in man, and>115g /m2 in woman, n=64) and non -LVH group (n=178), all patients were monitored 24-hour ambulatory blood pressure.Results LVH group showed higher levels of 24-hour pulse pressu...
