由于血压和心率反应的压力和动态措施的实验室措施之间的对应关系是最佳的，本研究测试了两个假设：动态血压测量升高期间的感知压力，相对于没有压力？在实验室应激时血压和心率反应升高的个体中，在感知应激时动态血压是否升高？这些问题在一组有工作的中年男性以及绝经前和绝经后女性中得到了解决。他们的生殖激素状态和患冠心病的风险不同。所有参与者进行了一系列的实验室研究，同时监测他们的生理参数，然后佩戴动态血压监测仪一天半。这个监测器在清醒的时候每半小时记录一次血压，同时参与者评估他们的情绪状态。在排除了那些报告压力水平没有变化的参与者之后。那些对实验室语言任务有心血管反应的人在感知压力期间表现出升高的动态血压水平。此外，一般来说。在受试者内部，感知压力的时间与动态血压升高相关。这些结果表明，实验室和现场测量血压之间的对应关系将得到改善，考虑到环境的情况下，在门诊评估和反应者-非反应者的实验室压力的人的特点。
Because the correspondence between laboratory measures of blood pressure and heart rate responses to stress and ambulatory measures is less than optimal, this study tested two hypotheses: Are ambulatory measures of blood pressure elevated during periods of perceived stress, relative to no stress? Are ambulatory blood pressures elevated during perceived stress among those individuals who exhibit elevated blood pressure and heart- rate responses to laboratory stress? These questions were addressed in a sample of employed, middle-aged men and premenopausal and postmenopausal women. who vary in reproductive hormone status, and in risk for coronary heart disease. All participants performed a series of laboratory studies while their physiological parameters were monitored and then wore an ambulatory blood pressure monitor for a day and a half. This monitor recorded blood pressure every half hour during the waking hours and at the same time the participants assessed their mood states. After excluding participants who reported no variability in stress levels. those who were cardiovascular reactors to a laboratory speech task exhibited elevated ambulatory blood pressure levels during periods of perceived stress. Furthermore, in general. periods of perceived stress were associated on a within subject basis with elevated ambulatory blood pressure. These results suggest that the correspondence between laboratory and field measures of blood pressure would be improved by taking into account the environmental circumstances during the ambulatory assessments and the person characteristics of reactor-nonreactor to laboratory stress.
