What factors are associated with decreased survival after acute ischemic stroke?
Several factors have been associated with decreased survival after acute ischemic stroke, including low blood pressure during the acute period, a U-shaped relationship between mortality and admission blood pressure, initial emergency department blood pressure, and blood pressure decrease during the acute phase. Other factors that have been associated with poor stroke outcomes include short-term blood pressure variability in the acute stroke period, post-stroke antihypertensives, parenteral fluid regimens, and short-term improvement of ischemic stroke.
