High Blood Pressure and Stroke
Story Updated: Mar 14, 2014
A broad review of past research suggests that patients with above-normal blood pressure face a higher risk for stroke even if their readings don't officially reach high blood pressure levels.
The conclusion published in Neurology follows a fresh analysis of 19 previous studies involving more than 760,000 patients. All of the studies spent 4 to 36 years tracking stroke risk among patients diagnosed with prehypertension. Prehypertension occurs when blood pressure levels exceed the ideal of 120 over 80 but remain below the 140 over 90 marker for actual hypertension.
In all, roughly 25 to 54% of participants were diagnosed as prehypertensive and nearly 20% of strokes occurred among that group.
Even after accounting for other risk factors such as smoking, diabetes, or high cholesterol the experts found that prehypertensive patients faced about a 66% greater chance for stroke than those with normal blood pressure.
The finding raises questions as to whether prehypertensive patients might benefit from the same blood pressure medications typically recommended for those with hypertension.
