    Abstract:
    OBJECTIVE: To evaluate the prognostic value of admission blood pressure in patients with acute ischemic stroke by determining whether it contributes to clinical outcome and vascular death. METHODS: We studied 230 consecutive patients admitted within the first 24 h after the onset of ischemic stroke. We used the first systolic and diastolic blood pressure measurements recorded on admission. The functional outcome was assessed on the basis of mortality or dependency (Rankin Scale > 3) at the 10-day and 6-month visits. RESULTS: High systolic blood pressure on admission was associated with poor outcome at the 10-day and 6-month visits, independent of the baseline risk factors but not of the severity of the initial stroke (odds ratio, 1.39; 95% confidence interval, 0.50-3.87). The spontaneous decrease in systolic blood pressure within the first 10 days was higher in patients with functional improvement. The admission blood pressure was not significantly associated with total and vascular deaths, except for a threshold effect of diastolic blood pressure. CONCLUSIONS: After an acute stroke, the relationship between blood pressure and clinical outcome depended on the severity of the stroke on presentation, and on the level and trend of the systolic blood pressure during the first 24 h.
