胸闷变异性哮喘是一种新认识的特殊类型哮喘，以胸闷或长叹气为主要或唯一的临床表现，由于无典型的支气管哮喘症状，往往易被误诊或漏诊。目前在儿童方面研究、报道不多。现就胸闷变异性哮喘的临床特点、发病机制、诊断和治疗相关的热点问题进行阐述，希望能提高临床医师对儿童胸闷变异性哮喘的诊治水平。“,”Chest tightness variant asthma(CTVA) is a newly recognized and special type of bronchial asthma, with the only main clinical manifestation of chest tightness or sighing respiration, but without wheezing and other typical symptoms of bronchial asthma.At the same time, the patients with CTVA are likely to be misdiagnosed in clinic practices.There are few studies on CTVA in children.This article focuses on hot issues about the clinical features, pathoge-nesis, diagnosis and treatment of CTVA, which hopes to enhance the diagnosis and treatment level of CTVA in children.
