本文对６０例脑梗塞急性期合并高血压的患者进行分组对比观察，发现未使用降压药物组其水肿带在病后２周和４周减少出现，应用降血压治疗组血压明显降低，但其病灶容积，２周、４周和１２周的神经功能缺损评分未见明显好转，提出降压治疗对该类病人并无益处，保持一定的动脉血压对维持脑梗塞急性期患者的脑血流量有重要作用。并结合临床和基础研究对其机理进行探讨。 In this paper, 60 patients with acute cerebral infarction complicated by hypertension were compared in groups and found that the use of antihypertensive drugs group edema zone in the 2 weeks and 4 weeks after the disease decreased, the application of antihypertensive treatment group decreased blood pressure, but its Focal volume, 2 weeks, 4 weeks and 12 weeks of neurological deficit score no significant improvement, proposed antihypertensive treatment of such patients did not benefit to maintain a certain arterial blood pressure in patients with cerebral infarction to maintain cerebral blood flow in patients with acute Important role. And the combination of clinical and basic research to explore its mechanism.
