Study Evaluates "Normal Range" Systolic Blood Pressure Levels After Ischemic Stroke and Risk of Recurrent Stroke
patients who experienced an ischemic stroke, systolic blood pressure levels of
less than 120 mm Hg, or higher than 140 mm Hg, were associated with an
increased risk of subsequent stroke, according to a study appearing in the Nov.
16 issue of JAMA, a theme issue on cardiovascular disease. This issue is
being released early online to coincide with the American Heart Association
stroke prevention guidelines suggest that larger reductions in systolic blood
pressure (SBP) are positively associated with a greater reduction in the risk
of recurrent stroke and define an SBP level of less than 120 mm Hg as normal. However,
the association of SBP maintained at such levels with risk of vascular events
after a recent ischemic stroke is unclear," according to background
information in the article.
