High Blood Pressure and Stroke Risk

admin - April 24, 2014

Slightly high blood pressure increases stroke risk.

A new study conducted by a research team shows that even blood pressure that is slightly higher than normal, but not high enough to be classified as high blood pressure, can increase the risk for stroke.

Normal blood pressure is 120/80 mmHg and the threshold for high blood pressure is 140/90 mmHg. Blood pressure numbers that reside in between the two can have a negative impact on health.


Blood Pressure Study

Nineteen studies involving more than 19,000 participants were conducted to study the effects of blood pressure and stroke. The findings of the study showed that participants who had what was classified as prehypertension were 66% more like likely to have a stroke when compared to those with a normal blood pressure. In addition, close to 20% of strokes that occurred over the course of the study were suffered by participants who had prehypertension.

The section of participants who had prehypertension were classified into two different groups, high (130/85 mmHg) and low (lower than the high but above the norm). Those in the high group were 95% more likely to suffer a stroke than those with normal blood pressure. Participants with low prehypertension were 44% more likely to have a stroke than those with blood pressure at normal levels.


Blood Pressure and Stroke Prevention

The Center for Disease Control states that 1 in 3 Americans have prehypertension, so not only preventing stroke but also prehypertension is extremely important.

The best way to prevent high blood pressure is by following a healthy diet and exercise plan. Following a diet that is high in fruits, vegetables, whole grains, low-fat dairy products, as well as being low in saturated fats and cholesterol has the ability to lower blood pressure by as much as 14mmHg.

The same goes for preventing stroke, since high blood pressure, high cholesterol, physical inactivity, obesity and poor diet are all risk factors.

If you are worried about high blood pressure and stroke we offer health screenings for both. Check our stroke page and high blood pressure page  for more information on who should get a screening, how often they should be performed, and a full list of risk factors.

    This is excellent advice. Many more ‘mature’ adults feel they
    are too aged to care and do not follow these principles in their every day life!

    I had extremely high blood pressure (200 / 98) and went to the doctor. They recommended that I go to see a cardiologist. After 3 weeks, I got in to see him. He was very rude to me – He asked me why I was there. I told him. He replied that he had looked at my records – 4 years old- and there was nothing wrong with me then and he was sure there was nothing wrong with me now. He could tell me all this without listening to my heart. I am 88 years old. I felt like he had told me I had reached my expiration date.
