A new study suggests that even slightly elevated blood pressure levels up the odds of suffering a stroke. It has been pegged as a risk factor for stroke for a long time.
The researchers studied 760,000 individuals who were followed for up to 36 years. They found that those with prehypertension (higher-than-optimal blood pressure) were 66 percent more likely to experience a stroke than those with normal blood pressure. The findings confirm that even mild to moderate levels of elevated blood pressure are important for determining stroke risk.
In another study, Chinese researchers from Southern Medical University in Guangzhou examined 19 separate studies on the risk of developing stroke in those with prehypertension, dividing them into high and low groups.
According to the researchers, it is a warning and there is a need for vigorous control of blood pressure to reduce the risk of stroke. Nearly 20 percent of the strokes suffered by study participants were due to pre-high blood pressure, according to the study.
The study is published in the latest issue of the journal Neurology.
