The present study analysed the charts of the patients admitted for acute stroke and assessed the relation between stroke mortality and initial blood pressure. Of the 388 patients admitted, 169 (44%) died. Mortality increased with advancing age and was higher in women, in hemorrhagic stroke (61%), and in patients with severe neurological deficit on admission. Average blood pressure on admission did not differ between the patients who died and those who survived. However, mortality was 42, 32, 57 and 62% in patients whose admission systolic blood pressure was, respectively, less than 160 mmHg, 160 to 199 mmHg, 200 to 249 mmHg and 250 mmHg or more. It described a similar curve when four categories of admission diastolic blood pressure were constituted. The data indicate a high case fatality rate in stroke patients. Mortality was higher in women; it increased with age and severe neurological deficit. The relation of stroke mortality to admission blood pressure suggests that it is not the lowest in patients with the lowest blood pressure, but in those with blood pressure level allowing the best brain perfusion after the onset of stroke.
本研究分析了因急性中风入院患者的病历，并评估了中风死亡率与初始血压之间的关系。在388例入院患者中，169例（44%）死亡。死亡率随年龄增长而增加，女性、出血性中风患者（61%）以及入院时伴有严重神经功能缺损的患者死亡率更高。死亡患者与存活患者的入院平均血压并无差异。然而，入院收缩压分别低于160 mmHg、160至199 mmHg、200至249 mmHg以及250 mmHg及以上的患者，死亡率分别为42%、32%、57%和62%。当按照入院舒张压的四个类别进行划分时，也呈现出类似的曲线。数据表明中风患者的病死率较高。女性死亡率更高；死亡率随年龄和严重神经功能缺损而增加。中风死亡率与入院血压之间的关系表明，并非血压最低的患者死亡率最低，而是血压水平能使中风发作后脑部获得最佳灌注的患者死亡率最低。
