The forearm vasodilator response to mental stress is multifactorial and widely variable among individuals. We evaluated the association between the heart rate and forearm vascular conductance (FVC) responses to a color word test in 101 healthy adults. We found a striking correlation between heart rate and FVC (r = 0.66, P < 0.001), which remained significant when controlling for subject characteristics, blood pressure, and catecholamines. This suggests that the mechanical stimulation is one of the key factors that contribute to the increase in FVC during mental stress.
前臂对精神压力的血管舒张反应是多因素的,个体之间差异很大。我们评估了101名健康成年人在色词测试中,心率与前臂血管传导性(FVC)反应之间的关联。我们发现心率与FVC之间存在显著相关性(r = 0.66,P < 0.001),在控制受试者特征、血压和儿茶酚胺后,这种相关性仍然显著。这表明机械刺激是精神压力期间导致FVC增加的关键因素之一。
