[Initial arterial pressure and prognosis of cerebrovascular accidents].
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.
