Time-dependent Changes of Blood Pressure in Cardiopulmonary Exercise Test for Females with Hypertension / 中国康复理论与实践

ABSTRACT

Objective:To explore the time-dependent changes of blood pressure with the increase of exercise intensity and its clinical significance in Cardiopulmonary Exercise Test for female patients with hypertension. Methods:From August, 2018 to August, 2019, 64 patients (hypertension group) who did not take β-receptor blockers and dihydropyridine calcium antagonists were selected from grade 1 and grade 2 hypertension women excluding myocardial ischemia with Cardiopulmonary Exercise Test. And 86 healthy women (non-hypertension group) excluding myocardial ischemia from the same period of Cardiopulmonary Exercise Test were selected as the controls for retrospective analysis. The time-dependent changes of blood pressure with the increase of exercise intensity were compared between two groups. Results:The blood pressures at resting for three minutes, anaerobic threshold and peak were significantly higher in the hypertension group than in the non-hypertension group (Z > 3.306, P < 0.001). There was no significant difference in peak oxygen uptake between two groups (Z = 1.549, P > 0.05). Conclusion:The blood pressure of the patients with grade 1 and grade 2 hypertension is prone to over elevation, who should pay more attention on blood pressure in sports and rehabilitation.
