Blood Pressure Danger: Fluctuating Levels
May 13, 2010
(Ivanhoe Newswire) -- We all know that
high blood pressure is dangerous, but a new study reveals having blood
pressure that fluctuates can be an even more serious problem.
Researchers found the risk of cerebrovascular disease is higher among those
who have fluctuating blood pressure in addition to high blood pressure.
Cerebrovascular disease includes stroke and other disorders affecting blood
vessels in the brain.
Investigators from Columbia University's Taub Institute in New York studied
686 older adults who did not have dementia. The participants had their blood
pressure taken during three visits at 24-month intervals and also underwent
testing with magnetic resonance imaging (MRI).
Results showed elevated blood pressure and
fluctuations in blood pressure were both associated with cerebrovascular
disease. Those with a higher average blood pressure and more fluctuation
were more likely to have cerebrovascular disease than those with either
"These findings suggest that management of blood pressure fluctuations, even
in normotensive older adults, may be beneficial in reducing the risk of
cerebrovascular disease and in maximizing healthy cognitive aging," the
study authors wrote.
