【摘要】 为了分析餐后低血压(PPH)患者的24h动态血压变化特点,选择150例原发性高血压患者进行24h动态血压监测,分成PPH组(n=85)和非PPH(n=65)。观察两组平均血压、血压负荷值、晨峰值、血压变异性等指标。结果显示,(1)PPH组年龄明显高于非PPH组(P<0.05);(2)PPH组患者24h及日间、夜间平均收缩压及平均收缩压负荷高于非PPH组(P<0.05),但舒张压无统计学差异(P>0.05);(3)PPH组患者血压变异性明显高于非PPH组(P<0.05);(4)PPH组患者血压晨峰数值及晨峰发生率明显高于非PPH组(P<0.05);(5)PPH组夜间血压下降率及非勺型率较非PPH组无统计学差异(P>0.05)。因此,PPH患者易发生于高龄患者,且具有收缩压、血压变异性增高,更易发生晨峰现象的特点。更多还原

【Abstract】 To analysis 24hambulatory blood pressure change characteristics of PPH,we choose 150cases patients with essential hypertension and proceed 24hambulatory blood pressure monitoring.They were divided into PPH group(n=85)and no PPH group(n=65).Observe average blood pressure,blood pressure load values morning surge and blood pressure variability of two groups.Results show:(1)The age of PPH group was obviously higher than that of the no PPH group(P<0.05);(2)The 24h,the average daytime and nighttime systolic blood pressure and systolic blood pressure load of PPH group is higher than the no PPH group(P<0.05),but no difference between the diastolic pressure(P>0.05);(3)Blood pressure variability of PPH group was obviously higher than that of the no PPH group(P<0.05);(4)The morning peak value and morning blood pressure peak value of the PPH group was significantly higher than that of PPH group(P<0.05);(5)The nighttime blood pressure drop rate and non dipper rate is no significant difference than that of PPH group(P>0.05).Therefore,PPH much easily occur in older patients and have a higher systolic blood pressure,blood pressure variability,even easily happen morning surge phenomenon.更多还原
