OBJECTIVE
The purpose of this study was to investigate how migrainous subjects and controls differ in their cardiovascular reactivity and recovery to a cognitive and an acute pain laboratory stressor.
BACKGROUND
Prior research suggests that individuals subject to migraine may respond physiologically to pain and stress differently than controls.
METHODS
Fifty-two women (26 with migraine and 26 controls) participated in a single laboratory session. Multiple cardiovascular responses to a cognitive (mental arithmetic) and an acute pain (cold pressor task) stressor were recorded with cardiac impedance methods. The cardiovascular responses measured included systolic and diastolic blood pressure, heart rate, cardiac output, stroke volume, and total peripheral resistance.
RESULTS
Results indicated that the migrainous participants displayed different cardiovascular recovery patterns for total peripheral resistance, cardiac output, and stroke volume following the termination of the mental arithmetic task.
CONCLUSIONS
These results support the hypothesis that individuals with migraine respond physiologically to stress differently than control individuals.
目的
本研究旨在调查偏头痛患者与对照组在心血管反应性以及对认知和急性疼痛实验室应激源的恢复情况方面有何不同。
背景
先前的研究表明，偏头痛患者在生理上对疼痛和压力的反应可能与对照组不同。
方法
52名女性（26名偏头痛患者和26名对照组）参与了一次实验室测试。采用心脏阻抗法记录了对认知（心算）和急性疼痛（冷加压任务）应激源的多种心血管反应。测量的心血管反应包括收缩压、舒张压、心率、心输出量、每搏输出量和总外周阻力。
结果
结果表明，在心算任务结束后，偏头痛参与者在总外周阻力、心输出量和每搏输出量方面表现出不同的心血管恢复模式。
结论
这些结果支持了以下假设，即偏头痛患者在生理上对压力的反应与对照个体不同。
