Abstract:
Objective To study the effects of exercise on hemodynamic parameters and cardiovascular humoral factors in the elderly patients with hypertension. Methods The modified Bruce assessment (MBA) was employed in an essential hypertension (EH) group (group 1, n =34) composed by elderly EH patients and a control group (group 2, n =31) composed of normal subjects. Heart rate (HR),systolic and diastolic blood pressure (SBP、DBP), and the quantum and duration of exercise (QE, DE) were explored, while the serum concentrations of nitric oxide (NO), endothelin 1(ET1), atrial natriuretic factor (ANF) and AngiotensinⅡ(AngⅡ) were measured at 3 min before and after treatment. Results There were no significant differences between groups 1 and 2 with regard to HR, SBP, DBP, total DE and peak QE before and after treatment, in addition, at the peak of exercise ( P 0.05). Pretreatment SBP and DBP were significantly and positively correlated with those at the peak of and after treatment ( r =0.648,0.630, P
