- In clinical practice, patients with acute stroke often have high blood pressure. The aim of this study was to investigate factors correlated with blood pressure elevation in 843 consecutive stroke patients on hospital admission to a nonintensive stroke unit. Using a multivariate analysis model, we analyzed the influence on admission blood pressure of sex, age, previous hypertension, cardiac failure, diabetes, type of stroke, impaired consciousness, and latency between onset of symptoms and admission. Previous hypertension was the strongest predictor (p less than 0.001) of elevated blood pressure on admission, followed by the presence of intracerebral hemorrhage (p less than 0.001). The latency between onset of symptoms and admission showed no correlation with blood pressure levels at hospitalization. Previously, high blood pressure levels on hospital admission have been shown to decline within a few days in hospital. We therefore hypothesize that mental stress on hospital admission may be a major factor in the blood pressure elevation seen in acute stroke.

- BACKGROUND AND PURPOSE: Patients with acute stroke are often found to have high blood pressures at hospital admission. Previous studies have shown variable results regarding the prognostic value of high blood pressure in acute stroke. The aim of this study was to investigate the prognostic value of admission blood pressure in a population-based sample of patients with acute stroke.METHODS: Eighty-five patients with intracerebral hemorrhage and 831 with ischemic disease were included in the study. The relations between admission blood pressure and 30-day mortality were studied by logistic regression analyses.RESULTS: High blood pressure in patients with impaired consciousness on hospital admission was significantly related to 30-day mortality in patients with intracerebral hemorrhage (P = .037) and in patients with ischemic disease (P < .0001). In patients without impaired consciousness, high blood pressure at time of admission was not related to increased mortality at 30 days.CONCLUSIONS: High admission blood pressure in alert stroke patients was not related to increased mortality. Stroke patients with impaired consciousness showed higher mortality rates with increasing blood pressure. However, this does not provide a basis for recommending antihypertensive therapy for such patients.
