““The relationship between BP and mortality in patients with stroke may be “U-shaped.” According to this notion, systolic BP (SBP) values above or below 140 to 180 mm Hg are associated with increased mortality. In the International Stroke Trial, SBP above 200 mm Hg was associated with an increased risk of recurrent ischemic stroke (50% greater risk of recurrence), while low BP (particularly <120 mm Hg) was associated with an excess number of deaths from coronary heart disease.””
