PURPOSE: This study attempted to show the relationship between exercise-induced hypertension response and arterial stiffness in men aged 50 years.
METHODS: The subjects of the study were adults male with exercise induced hypertension group (n=45, age 56.22±2.60 years) and control group (n=61, age 56.01±1.57 years) who had undergone exercise test and arterial stiffness test. Exercise induces hypertension is defined as a peak systolic blood pressure ≥210mmHg during treadmill tests. Exercise stress test was conducted using modified Balke protocol. Arterial stiffness was assessed based on brachial-ankle pulse wave velocity (baPWV).
RESULTS: Exercise induced hypertension group showed significantly higher baPWV than that of control group (1416.5±154.09cm/sec vs. 1309.5±127.76cm/sec, p<.001). The peak systolic blood pressure was correlated with the resting heart rate (r=0.198, p<.05), resting systolic blood pressure (r=0.190, p<.05), and baPWV (r=0.461, p<.001). In multiple linear regression analysis, we found that the baPWV was a significant predictor of peak systolic blood pressure (β=0.429, p<.001).
CONCLUSIONS: Exaggerated blood pressure response to exercise was associated with arterial stiffness.
