Objective To explore the relationship between blood pressure and hemorrhagic cerebral infarction. Methods Retrospectively reviewed clinical data of 242 patients with acute cerebral infarction, then all patients with hemorrhagic cerebral infarction were selected. The distributions of different level of blood pressure (＞180/110mm Hg;90/70～180/110mm Hg;＜90/70mm Hg) were compared between the patients with or without hemorrhagic cerebral infarction, as the same, different prognosis were compared among the patients with hemorrhagic cerebral infarction based on the different level of blood pressure. Results Of the total patients with acute cerebral infarction,4. 1%(10) presented with blood pressure＜90/70mm Hg,88. 0%(213) with blood pressure 90/70～180/110mm Hg and 7.9%(19) with blood pressure＞180/110mm Hg. In all the patients,20 cases(8. 3%) with hemorrhagic cerebral infarction,among which,60.0%(12) patients with blood pressure＞180/110mm Hg and with 7 cases died, 10.0%(2) patients with blood pressure＜90/70mm Hg and with 1 case died,30.0%(6) patients with blood pressure 90/70～180/110mm Hg and with 2 cases died. The distribution of patients with blood pressure＞180/110mm Hg in those two type of cerebral infraction were statistically significant (P=0. 000) ,the ratio seemed higher in patients with hemorrhagic cerebral infarction, and among the patients with hemorrhagic cerebral infarction, the distribution of prognosis were the same statistically significant based on the diffetent level of blood pressure, among which, patients with blood pressure＞180/110mm Hg(P =0.041) or＜90/70mm Hg(P =0.037) seemed like to have a higher mortality. Conclusion Severe high blood pressure(＞180/110mm Hg) should be one of the high risk factors for patients with hemorrhagic cerebral infarction,when blood pressure＞180/110 mm Hg or ＜90/70mm Hg happened in the pathogenesis, patients always be with poor outcome. So, making proper control strategy of blood pressure for patients with hemorrhagic cerebral infarction was with significance to defend its' happening and prognosis' improvement.
