[Systolic blood pressure reduction in patients with intracranial hemorrhage and functional prognosis].

Background: Acute intracerebral hemorrhage affects annually more than 1 million people worldwide. Chronic systemic arterial hypertension is the most important modifiable risk factor for spontaneous intracerebral hemorrhage. Objective: To determine the relationship between the decrease in systolic blood pressure (SBP) in patients with intracranial hemorrhage and their short-term functional prognosis. Material and methods: Observational, longitudinal, prospective study in patients with intraparenchymal hemorrhage secondary to hypertensive dyscontrol, older than 18 years, of both sexes. Blood pressure was recorded at admission, every hour during the first 6 hours and every two hours from 8 to 24 hours after admission. Functionality was assessed using the modified Rankin scale at admission, at 6 and 24 hours after admission. Results: 58 patients were included, in whom the reduction of systolic blood pressure at admission was 17.04% and at 24 hours was 31.3 mm Hg; the mean systolic blood pressure was 183.62 mm Hg as opposed to 152.3 mm Hg at discharge (p < 0.001). Conclusions: In the first 6 hours, reduction in ASR is significantly associated with hospital outcome in patients with intracranial hemorrhage. A linear association was observed with improvement and favorable functional prognosis as measured by the modified Rankin scale.
