    Abstract:
    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.
