Objective: To observe the changes of blood pressure in acute stage of cerebral infarction and its influential factors. Methods: One hundred and twenty-two patients with confirmed acute cerebral infarction were monitored for blood pressure for one week and divided into hypertension group and normotensive group according to blood pressure to analyze the influencing factors. Results: The vast majority of patients had elevated blood pressure but dropped to pre-morbid levels one week later.
