It would be so simple for optimizing primary prevention if our doctors would just put together a diet stroke protocol that reduces blood pressure using commonly available foods and supplements. But that won't occur because we have no one in the stroke medical world that has two functioning neurons they can rub together. You, your children and grandchildren are screwed.
Pre-stroke CV risk factors may indicate higher stroke, dementia risk
Portegies MLP, et al. Stroke. 2016;doi:10.1161/STROKEAHA.116.014094.
According to new research, CVD
risk factors such as high BP before a first stroke confer higher risk
for subsequent stroke and dementia up to 5 years later.
“We already know that stroke
patients have an increased risk of recurrent stroke and dementia. What
we didn’t know was whether this increased risk persists for a long time
after stroke and whether heart disease risk factors present before the
first stroke influenced the risk of recurrent strokes or dementia,” M. Arfan Ikram, MD, PhD, from
Erasmus University Medical Center in Rotterdam, Netherlands, said in a
press release. “Our study found these risk factors influence future
stroke and dementia and the risks persist for an extended period in some
patients.”
The researchers analyzed based on propensity
matching 1,237 patients with first-ever stroke and 4,928 participants
without stroke from the population-based Rotterdam Study. Participants
were matched based on sex, age, examination round, and date of
selection. The outcomes of interest were stroke and dementia.
Ikram and colleagues calculated incidence
rates of stroke and dementia for both groups and determined the
population-attributable risk of prestroke CV risk factors for stroke and
dementia.
Up to 1 year after first stroke, those with
stroke had a threefold increased risk for stroke and a twofold increased
risk for dementia compared with those without stroke, Ikram and
colleagues wrote.
The researchers calculated that in the group
with stroke, 39% (95% CI, 18-66) of recurrent strokes and 10% (95% CI,
0-91) of cases of dementia after stroke could be attributed to CV risk
factors before stroke. The rates were similar in the group without
stroke.
“Long-term risks of recurrent stroke and
poststroke dementia remain high and are substantially influenced by
prestroke risk factors, emphasizing the need for optimizing primary
prevention,” the researchers wrote. – by Dave Quaile
