治疗前动态血压监测对高血压病患者左室重塑类型的预测

目的:探讨原发性高血压(EH)患者动态血压对左室重塑类型的预测价值。方法:84名EH患者按动态血压值分为两组,分别进行心脏超声检测,比较左室重量指数(LVMI)及左室重塑的特点。结果:平均血压值较高的B组LVMI、左室肥厚与向心性肥厚的发生率均高于平均血压值低的A组(均P<0.01),正常构型发生率低于A组(P=0.01)。LVMI与平均收缩压、平均舒张压均呈显著的正相关关系(均P<0.05)。结论:动态血压值高的EH患者LVMI较大,左室肥厚与向心性肥厚的发生率较高。动态血压对EH患者左室重塑的类型有强烈的预测价值。

Predictive value of ambulatory blood pressure monitoring on left ventrlcular remodeIHng in essential hypertension patients before treatment

Objective:To study the predicdive value of ambulatory blood pressure monitoring(ABPM) on left ventricular(LV) remodelling in essential hypertension( EH).Methods:Eighty-four impatients with EH were divided into two groups accordin g to 24 hours ambulatory blood pressure,echocardiography was performed and gende r-specific values for LV mass index(LVMI) were measured by echocardiography.Resu lts:The left ventricular mass index and incidence of hypertrophy and concetric r emodelling of left ventricle in patients with higher average blood pressure(grou p B) were significantly higher than those in patients with lower averge blood pr essure(group A)(P<0.01).Multivariate analyses revealed that LVMI was positively correlated with all of ABPM parameters(all P<0.05),and ABPM was the most valuabl e predictive factor.Conclusion:ABPM was the valuable method to predict the patte rn of LV remodelling in EH patients.
