The Change of Arterial Stiffness in Prehypertensive People

Objective To investigate the changes of arterial stiffness in prehypertensive people and the effect of combined miltiple risk factors on it.Methods 158 subjects with no obvious target organ damage were allocated into 3 groups,normotensive(n=56),prehypertensive with 1 or without cardiovascular risk factors(n=50),prehypertensive with 2 or above cardiovascular risk factors(n=52).Results(1)The BaPWV of prehypertension was higher than normotensive.(2)The BaPWV of prehypertensive with 2 or above cardiovascular risk factors was higher than prehypertensive with 1 or without that.Conclusion Prehypertensive patients already had change of compliance in large arteries even no obvious target organ damage was found.With multiple risk factors concurrent effect,they could increase big arterial stiffness much more significantly.
