原发性高血压左心室肥厚与动态血压负荷值的关系

摘要

Objective:to study the relations between blood pressure load and left ventricular hypertrophy(LVH).Methods:119 patients eligible for criteria of essential hypertension by WHO were divided into LVH groups(n=65)and nonLVHgroups(n=54),and both groups were measured with ambulatory blood pressure monitoring.Results:The 24-hour.nighttime systolic blood pressure(SBP)and diastolic blood pressure(DBP) loads in two groups were high significantly different (p＜0.001).2.The daytime SBP loads in two groups were high significantly different(p＜0.001),but DBP loads were significantly different(p＜0.05).3.The blood loads of essential hypertension patients were higher than those of normal blood pressure people.Conclusions:As a good indicator,the blood pressure load could be applicated clinically to assess and predict the LVH of essential hyertension.%目的：探讨动态血压负荷值与原发性高血压左心室肥厚的关系。方法：将119例原发性高血压患者分为54例无左心室肥厚组和65例伴左心室肥厚组，并进行24h动态血压监测。结果：1、两组患者24小时、夜间收缩压和舒张压负荷值均有高度显著性差异(P＜0.001)；2.白昼两组收缩压负荷值有高度显著性差异(P＜0.002)，舒张压负荷有显著性差异(p＜0.05)；3.两组高血压患者血压负荷值明显高于血压正常者血压负荷值。结论：血压负荷值，特别是夜间血压负荷值是高血压左心室肥厚评价和预测的良好指标，有广泛的临床应用价值。
