本文报道的是１０６例５０岁以上支气管哮喘病人临床资料。他们占同期哮喘病人总数的４４％，其中６７．９％于４０岁以后起病，起病高峰位于更年期阶段，同非老年哮喘病人一样，过敏及家族遗传因素也同样较普通存在（Ｐ＞０．０５）。与非老年哮喘病人相比，夜间哮喘现象较为普通。在哮喘发作时血氧下降更明显（Ｘ１１．４ｍｍＨｇ，Ｐ＜０．０ｌ），心脏亦更容易受累（Ｐ＜０．０１），应当引起临床医师的重视。 This article reports the clinical data of 106 patients over the age of 50 with bronchial asthma. They accounted for 44% of the total number of asthma patients in the same period, of which 67.9% were onset after the age of 40 and their peak onset was in the menopause. As with non-elderly asthmatics, allergy and familial hereditary factors were equally common (P> 0 .05). Compared with non-elderly asthmatic patients, nighttime asthma is more common. The decrease of blood oxygen was more obvious in the asthma attack (X11.4mmHg, P <0.01), and the heart was more likely to be involved (P <0.01), which should be taken seriously by clinicians.
