The authors evaluated the incidence of a psychological stressor in the modification of blood pressure induced by the cold pressor test in normotensive and medicated hypertensive subjects. The study was carried out in two stages: In the first, 28 (14 normotensive and 14 hypertensive) subjects were administered a cold pressor test. Fifteen days later, 14 subjects repeated the same experiment. The remaining 14 subjects (7 hypertensive and 7 normotensive) also repeated the cold pressor test, with the difference that, to add a stressful psychological situation, the physician "abandoned" them at the beginning. The addition of the psychological stress significantly increased only systolic blood pressure in both the hypertensive and the normotensive subjects. Furthermore, the hypertensive subjects did not recover their basal blood pressure values following the cold pressor test when the psychologically stressful situation had been added. These results show the importance of considering psychological aspects when applying physical pressor tests.
作者评估了心理应激源在正常血压和药物治疗的高血压受试者中对冷加压试验诱导的血压变化的影响。该研究分两个阶段进行：第一阶段，对28名受试者（14名正常血压者和14名高血压患者）进行冷加压试验。15天后，14名受试者重复相同实验。其余14名受试者（7名高血压患者和7名正常血压者）也重复冷加压试验，不同之处在于，为增加心理应激情况，医生在开始时“抛弃”了他们。心理应激的增加仅显著提高了高血压和正常血压受试者的收缩压。此外，当加入心理应激情况时，高血压受试者在冷加压试验后并未恢复其基础血压值。这些结果表明，在应用物理加压试验时考虑心理因素的重要性。
