[Evaluation of arterial blood pressure and heart rate during exercise tests in patients with essential hypertension in different stages of hypertension].

This article analyses the changes of arterial blood pressure and heart rate (HR) in 120 patients with essential hypertension during two successive exercise tests. Before and during the tests, the patients did not take any hypertensive drugs. The obtained measuring results at exercise tests and restitution were the basis for the calculating regression equations. Then the results were analyzed statistically (p < 0.05) and clinically (drop or increase of arterial systolic blood pressure value (SAP) or/and diastolic (DAP) by 5 mmHg, and HR by 5 beats per minute). The HR response was comparable in both test for all tested groups both in exercise and restitution periods. For the additional sex division the HR value in all subgroups women was lower in the second test and satisfies the condition of statistic and clinical significance. In the second test SAP was lower only in the group of mild pressure and in the group without organ changes (stage I WHO) during exercise. At restitution periods the SAP values were lower in all the tested groups with the exception of the group with borderline hypertension. DAP was lower in the second test in all the tested groups both in exercise test and in the restitution period. It is also shown that the quantity of DAP difference in the second test is the greater, the higher value of DAP at restitution is.
