Abstract		The aim of the study was to find out whether hypertensive reaction induced by exercise test, as well as the patient's body weight and heart rate can predict the development of hypertension. In order to test this hypothesis we studied two groups of subjects who underwent their first submaximal stress test using a bicycle in the years 1984-1987. One group (HT group) consisted of 13 subjects with hypertensive reaction to exercise testing, while another group (K group) comprised 14 controls in whom stress testing triggered no hypertensive reaction. Hypertensive reaction was defined as an increase in systolic blood pressure over 200 mm Hg, and-or an increase in diastolic blood pressure by 15 mm Hg, if thus exceeding 90 mm Hg, occuring during a graded submaximal exercise test. Stress testing using the same protocol was repeated in both groups in 1994. Nine subjects in HT group and 2 controls were found to have developed hypertension. Hypertensive subjects had higher body weight than normotensive subjects heart rate was seen to have declined over the past 8 years. We assume that a simultaneous increase in blood pressure and heart rate may be due to a common underlying mechanism, i.e. increased sympathetic tone. The results of this study support the hypothesis that hypertensive reaction triggered by exercise testing and the patient's body weight have a prognostic value in hypertension. Our results, however, failed to prove that the heart rate at rest can predict the development of arterial hypertension.
