Abstract： Objective The purpose of the study was to investigate the standard and method of regula-ting blood pressure in the acute cerebral infarction with heart failure. Methods 100 patients who suffered from acute cerebral infarction with heart failure(heart function Ⅱ-Ⅳ grade)in 24 hours were divided randomly into Sodium Nitroprusside treatment group and control group. There was no significant difference about ages, blood pressure,neurologic impairment score and heart failure degree of the patients in two groups. Results Control-ling blood pressure of patients with heart function Ⅱ grade was benefit to heart failure ,but the perfusion of cere-bral blood flow was influenced seriously compared with control group. Reasonably controlling blood pressure of patients with heart function Ⅲ-Ⅳ grade could improve heart function,and the perfusion of cerebral blood flow could also be improved compared with control group. Conclusion Reasonably control blood pressure of patients with acute cerebral infarction with heart failure was benefit to heart function, cerebral hemodynamics and nerval function.
