There is substantial evidence indicating that hypertension (blood pressure equal to or above 140/90) increases stroke risk, but a new study suggests that pre-hypertension (blood pressure above 120/80 but below 140/90) may be associated with an increased risk of stroke as well.

The study used records from over 500,000 adults who participated in blood pressure and stroke related studies. Researchers discovered that those who were pre-hypertensive had a 55% increased risk of stroke. Those with blood pressure in 130-139 range systolic were 79% more likely to suffer from a stroke than those with normal blood pressure.

If further research confirms these findings it could have a significant impact on blood pressure treatment recommendations.
