Ambulatory blood pressure variability within the first 24 hours after admission and outcomes of acute ischemic stroke

Our purpose was to evaluate the value of blood pressure variability within the first 24 hours after admission in predicting outcomes of patients with acute ischemic stroke (AIS). A greater variability in systolic blood pressure (adjusted odds ratio [OR] = 1.801, 95% confidence interval [CI] = 1.167-2.779) was associated with poor discharge outcome, especially for non diabetics (adjusted OR = 1.948, 95% CI = 1.184-3.205) and cardioembolism-related patients with AIS (OR = 7.650, 95% CI = 1.370-42.713). However, this correlation was not observed with a long-term (3-month or 6-month) outcome in patients with AIS. There was no association between diastolic blood pressure variability within the first 24 hours after admission and outcome. In conclusion, systolic blood pressure variability within the first 24 hours after admission is a critical predictor for short-term outcome of patients with AIS.
