目前人们对蛛网膜下腔出血(SAH)的病因学仍不完全了解。表现为一秒用力呼气量(forced expiratory volume in 1 second,FEV1)和用力肺活量(low forced vital capacity,FVC)减少的肺功能降低是心血管疾病的预测因子,但肺功能的降低是否是SAH的危险因素仍不清楚。本前瞻性队列研究探讨了肺功能和SAH发病率的关系。从1974年至1992年,男性20534例,女性7237例(平均年龄44岁)接受了包括肺活量测定(spirometry)的健康体检项目的检查,平均随访26年,观察年龄、身高、标准化FEV1,FVC,and FEV1/FVC At present, the etiology of subarachnoid hemorrhage (SAH) is still not fully understood. Decreased pulmonary function, manifested as forced expiratory volume in 1 second (FEV1) and decreased forced vital capacity (FVC), is a predictor of cardiovascular disease but is lung function reduction whether SAH The risk factors are still not clear. This prospective cohort study explored the relationship between pulmonary function and the incidence of SAH. From 1974 to 1992, 20,534 males and 7,237 females (mean age 44 years) underwent a physical examination including spirometry. The patients were followed up for an average of 26 years. The effects of age, height, standardized FEV1, FVC, and FEV1 / FVC
