摘    要:目的 观察前部缺血性视神经病变(anterior ischemic optic neuropathy,AION)患者24h动态血压、心率变化特征。 方法 分别对AION和与其性别、年龄相匹配的无AION对照组患者各50例进行24 h血压、心率测量,并绘出由夜间(23:00~5:00)到白天(6:00~22:00)的变化曲线。 结果 两组患者之间白天的血压、心率比较差异无显著性意义(P>0.05),白天血压、心率均高于夜间(t=3.63,3.16; P<0.05)。夜间AION组血压、心率低于对照组(t=3.82,1.77; P<0.01,0.05),2:00~7:00血压,尤其舒张压AION组低于对照组(P<0.01),AION组心率于2:00~5:00低于对照组(女 P<0.05,男 P<0.01),夜间到白天的血压上升曲线AION组呈现缓慢的、波动较大的上升曲线,而对照组则为急剧的、平稳的上升曲线。 结论 AION患者存在着对血压调节的某种缺陷;2:00~7:00血压、心率的低点可能是AION发生的易感时段。 (中华眼底病杂志, 2002, 18: 259-261)

Abstract:Objective To observe the characteristics of changes of 24-hour ambulatory blood pressure and heart rate of 50 patients with anterior ischemic optic neuropathy (AION). Methods Fifty patients with AION and the persons without in the control group, which had the same number, gender and age as the patients with AION, underwent 24-hour ambulatory blood pressure and heart rate measurement. Results Both groups had no difference in mean blood pressure and heart rate during the daytime (t=1.25,0.93;P>0.05), higher than those in the nighttime (t=3.63,3.16;P<0.05). Mean blood pressure and heart rate of AION group at night were lower than those of the control group (t=3.82,1 77;P< 0.01,0.05), especially diastolic pressure of AION group was lower than that of the control group from 2 am to 7 am (P<0 01),as well as the heart rate from 2 am to 5 am (P<0.05 or P<0.01). The curves of blood pressure of AION group showed more gradual and fluctuant rising, while those of the control group showed sharper and less fluctuant rising. Conclusion According to the curves of blood pressure rising, the patients with AION may have some defects in auto-regulatory mechanism of blood pressure. The low spots of blood pressure and heart rate in early morning, which might be a critical point leading to AION.
Keywords:Optic nerve diseases/diagnosis  Blood pressure  Heart rate
