作者为研究中风发生率的昼夜变化,对牛津地区进行了4年的群体调查。对象该地区大约105 000人口中首次中风者675例。其中脑梗塞545例,原发性脑内出血66例,蛛网膜下腔出血33例,分型不明者31例。结果在分型明确的644例中,578例能分出自已发作是在睡眠中(亦即在睡眠中醒来时发现中风)还是在清醒时,其中睡眠中发作者占脑梗塞病例的25%(135/545例),占原发性脑内出血病例的17%(11/66例),占蛛网膜下腔出血的0%(0/33)。为保守计,即使把不知道
In order to study the diurnal changes in the incidence of stroke, the authors conducted a 4-year population survey in Oxford. Target 675 first-time stroke victims in some 105,000 people in the area. Including 545 cases of cerebral infarction, 66 cases of primary intracerebral hemorrhage, 33 cases of subarachnoid hemorrhage, 31 cases of unknown type. Results Among the 644 cases with definite type, 578 cases could distinguish whether the episode occurred during sleep (that is, stroke was found when waking up in sleep) or when awake, in which the onset of sleep accounted for 25% of cases of cerebral infarction (135/545 cases), accounting for 17% (11/66 cases) of primary intracerebral hemorrhage cases and accounting for 0% (0/33) of subarachnoid hemorrhage. To conservative, even if do not know
