To assess the role of dynamic stress test in hypertension three normotensive and ten borderline or mild hypertensive subjects were studied by means of the intraarterial Oxford technique. In all of the subjects the intraarterial monitoring lasted for 12 hours; during the recording a graded maximal bicycle exercise test was performed. Five patients considered hypertensive on the basis of their office blood pressure readings showed normal average 12-hour intraarterial recordings. Systolic blood pressure increase during ergometry ranged from 22 to 57 mmHg; exertional pressure readings were strictly related to average 12 hours intraarterial blood pressure (r = 0.92; p less than 0.001). No correlation was found between resting blood pressure and the exertional pressure taken with the auscultatory method. These data indicate that the level that blood pressure attains during ergometry primarily depends on the resting blood pressure values, and therefore do not justified the separation between normo and hyperreactive subjects as some authors have done. In conclusion, dynamic exercise may be a useful diagnostic test for hypertension but has no predictive value for either the development of high blood pressure or the progression from borderline to more severe forms of hypertension.
为评估动态应激试验在高血压中的作用，采用动脉内牛津技术对3名血压正常者和10名临界或轻度高血压患者进行了研究。所有受试者的动脉内监测持续12小时；记录期间进行了分级最大自行车运动试验。5名根据诊室血压读数被认为患有高血压的患者，其12小时动脉内平均记录显示正常。运动试验期间收缩压升高范围为22至57 mmHg；运动时的血压读数与12小时动脉内平均血压密切相关（r = 0.92；p < 0.001）。静息血压与听诊法测得的运动时血压之间未发现相关性。这些数据表明，运动试验期间血压达到的水平主要取决于静息血压值，因此，不像一些作者所做的那样，没有理由区分反应正常和反应过度的受试者。总之，动态运动可能是一种有用的高血压诊断试验，但对高血压的发生或从临界高血压进展为更严重形式的高血压均无预测价值。
