The authors study the vascular reactivity to cold exposure in 48 normal subjects and 37 Raynaud's phenomenon (20 Raynaud's diseases, 9 digital arteritis, and 8 acrocyanosis). The haemodynamic profile of primary Raynaud's diseases is quite different: important drop in digital systolic pressure after cold (-27%), suppression of the postischemic hyperaemia (-47%). Digital arteritis has a lower digital pressure at rest (-24 mm Hg), a higher pressure gradient between the arm and the finger (30 mm Hg) and a reduced digital blood flow. The acrocyanotic hands are the coldest, the recovery time is long and the blood flow low.
作者研究了48名正常受试者以及37例雷诺现象患者（20例雷诺病、9例指动脉炎和8例手足发绀症）对冷暴露的血管反应性。原发性雷诺病的血流动力学特征有很大不同：冷暴露后指收缩压显著下降（-27%），缺血后充血受到抑制（-47%）。指动脉炎患者静息时指压较低（-24 mmHg），手臂与手指之间的压力梯度较高（30 mmHg），指血流量减少。手足发绀症患者的手部温度最低，恢复时间长，血流量低。
