Systolic blood pressure levels of less than 120 mm Hg or higher than 140 mm Hg are associated with an increased risk of subsequent stroke in patients who experience ischemic stroke, according to a recent study.
Researchers at the University of California evaluated the association of systolic blood pressure maintained within a low to normal range against high to normal range with clinical outcomes among patients who recently experienced an ischemic stroke.
Compared with the high-normal systolic blood pressure level group, risks of the secondary outcome were significantly higher in the very low-normal group, in the low-normal group, in the high group, and in the very high group."
The results indicate that there may be thresholds of benefit for short-term to longer-term systolic blood pressure levels after an ischemic stroke.
A previous study has advocated preventative systolic blood pressure treatment to protect against stroke risk in older adults.
Researchers at the University of Yale discovered strong clinical evidence to support the treatment of persons with systolic blood pressure of at least 160 mm Hg.
