Evaluation of aortic elastic properties in patients with exaggerated systolic blood pressure response to exercise testing.

PMID 24832001


We aimed to evaluate the aortic elastic properties in subjects with hypertensive response to exercise stress test (HRE). Sixty-six patients were divided into two groups (33 patients in HRE group and 33 patients in normotensive group). Baseline demographic characteristics were similar. The mean aortic stiffness index (ASI) was significantly higher (p=0.001) whereas aortic distensibility (AD) was significantly lower (p=0.029) in patients suggesting HRE. The C-reactive protein levels of patients with HRE was higher in the HRE group (p=0.03). AD was significantly correlated with age (r=-0.406, p<0.001), pre-test systolic blood presure (SBP) (r=-0.427, p<0.001), peak exercise SBP (r=-0.307, p=0.01), peak exercise diastolic blood presure (DBP) (r=-0.315, p=0.008), and recovery time (3 min) SBP (r=-0.497, p=0.004). Age (β=-0.506, p=0.003) and peak DBP (β=-0.322, p=0.049) were independent predictors of decreased AD. In conclusion, we found a deterioration in arterial elastic properties in patients with HRE.
