Abstract: Objective To explore the influence of diastolic blood pressure to prognosis of patients with acute cerebral infarction. Methods Clinical data of 200 patients with acute cerebral infarction were retrospectively reviewed Patients were divided into three groups based on diastolic blood pressure(DBP)when admission;hypotensive group(DBP＜70 mm Hg),normotensive group(DBP;70-90 mm Hg)and hypertensive group(DBP ＞ 90 mm Hg).Constituent ratio of patients with different level of DBP were calculated and prognosis were compared among the three groups. Results Of all the total patients with acute cerebral infarction,8%(16)presented with hypotension,12%(24)were normotensive and 80%(160)were hypertensive.In the hypotensive group,50%(8)patients died as compared to 17%(4)in normotensive group and 38%(60)in hypertensive group,among all the cases,patients with bypotension or hypertension seemed like to have a higher mortality than normotensive group(P=0.037;x2=3.993,P=0.046),and there was no significant diffenence between two group with hypotension or hypertension. Conclusion The patients with diastolic blood pressure of less than 70 mm Hg or more than 90 mm Hg were predictors of poor outcome.
