Even people with moderately high blood pressure are at increased risk of stroke, this is the conclusion reached by scientists from the University of California.
Hypertension is known to have a powerful risk factor for stroke and heart disease, but predeparture was not considered a serious symptom. A third of the U.S. population pressure slightly higher than normal as it turned out, this increases the risk of stroke by 55 percent compared with people with normal blood pressure.
Hypertension is a systolic pressure of 140 mm RT.article and above and a diastolic pressure of 90 mm RT.article and above. Normal is 120/80 mm of the national heart Institute was named prehypertensive indicators between 120 to 139 or 80-89 mm RT.article
The greatest danger is a high diastolic blood pressure pre-hypertension, people with pressure from 85 to 89 percent are 79 percent more likely to get a stroke. Also at risk are people under the age of 65 years, after this age, the risk to get stroke equal.
Scientists from the University of California analyzed data for the 12 previous studies, in which took part 518 thousand people from the USA and Asia. Participants were observed from 3 to 32 years. Even after making adjustments for age, gender and lifestyle, it became clear that prehypertensive significantly increases the risk of stroke.
