方法1985年至1989年在巴塞罗那招募了所有因哮喘或COPD急诊室服务的患者。通过1985年至1989年加泰罗尼亚死亡率登记处的队列记录联系获得生命状态。[3]共有9987人（初始队列中的15517人）被诊断为COPD，其中3245人在1985年至1989年期间死亡，并用于本分析。心血管死亡率是指《国际疾病分类》（ICD-9）的编码390至459，呼吸系统死亡率是指编码460至519。
MethodsAll patients attending emergency room services for either asthma or COPD were recruited during the years 1985 to 1989 in Barcelona. Vital status was obtained through record linkage of the people of the cohort with the Catalonia Mortality Registry for the years 1985 to 1989. 3 A total of 9987 people (of the 15 517 in the initial cohort) had a diagnosis of COPD, 3245 of whom died in the period 1985 to 1989 and were used in this analysis. Cardiovascular mortality refers to codes 390 to 459 and respiratory mortality to codes 460 to 519 of the International Classification of Diseases (ICD-9).
