高血压患者动态血压及踝臂指数与左室质量指数相关性研究

Correlation among Ambulatory Blood Pressure,Ankle Brachial Index and Left Ventricular Mass Index in Hypertensive Patients

目的探讨高血压患者动态血压及臂踝指数(ABI)与左室质量指数(LVMI)的关系。方法对578例高血压住院患者进行回顾性分析。结果患者的一般临床资料、ABI、LVMI值在不同性别间无显著性差异。相关分析显示,LVMI与24h平均收缩压(r=0.245,P=0.000)、24h平均舒张压(r=0.158,P=0.000)正相关;与夜间收缩压下降率(r=-0.104,P=0.012)、夜间舒张压下降率(r=-0.132,P=0.001)负相关;与ABI无相关性。多元逐步回归分析显示,24h平均收缩压(P=0.000)是LVMI的独立相关因素。结论 LVMI与ABI不存在相关性,而与24h平均收缩压独立相关。

Objective To analyze the relationship among ambulatory blood pressure（AMBP）,ankle brachial index（ABI） and left ventricular mass index（LVMI） in hypertensive patients.Methods 578 hypertensive inpatients were reviewed.Results The general clinical data of selected patients,their ABI,LVMI were not different significantly between male and female.The correlation analysis showed that LVMI was positively correlated with the 24-hour average systolic（r=0.245,P=0.000） or diastolic（r=0.158,P=0.000） blood pressure,whereas negatively correlated with percent of systolic（r=-0.104,P=0.012） or diastolic（r=-0.132,P=0.001） blood pressure declining at night.No significant correlation was found between LVMI and BMI.Multiple regression analysis revealed that LVMI was significant independently positive correlated with 24-hour average systolic blood pressure（P=0.000）.Conclusion LVMI does not correlate with ABI,but independent positive related with 24-hour average systolic blood pressure.
