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

Predictive value of ambulatory blood pressure monitoring on left vent ricular remodelling in essential hypertension patients before treatment

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。

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 according to 24 hours ambulatory blood pressure,echocardiography was performed and gender-specific values for LV mass index （LVMI） were measured by echocardiography.Results：The left ventricular mass index and incidence of hypertrophy and concetric remodelling of left ventricle in patients with higher average blood pressure（group B） were significantly higher than those in patients with lower averge blood pressure（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 valuable predictive factor.Conclusion：ABPM was the valuable method to predict the pattem of LV remodelling in EH patients.
