[Research advances in chest tightness variant asthma].

Chest tightness variant asthma (CTVA) is a special type of asthma with chest tightness as the only or main symptom. Due to the lack of typical asthma symptoms such as coughing, wheezing, shortness of breath, and positive signs in chest, it is easy to be missed or misdiagnosed in clinical practice. The onset of chest tightness variant asthma is insidious, and there is few research and attention both domestic and international, so there is no unified diagnosis and treatment standard especially in childhood asthma. This article expounds the related research advances in chest tightness variant asthma, in order to increase clinical attention and provide reference and basis for the prevention of the disease as well as the formulation of diagnosis and treatment strategies.胸闷变异性哮喘（chest tightness variant asthma，CTVA）是一种特殊类型的哮喘，以胸闷作为唯一或主要症状，由于缺乏咳嗽、喘息、气促等典型哮喘的症状和肺部阳性体征，在临床工作中易被漏诊或误诊。胸闷变异性哮喘起病隐匿，国内外相关研究和关注甚少，尤其在儿童哮喘中尚无形成统一诊疗标准。本文阐述了胸闷变异性哮喘的相关研究进展，以期提高临床的关注，并为疾病的预防和诊疗策略的制定提供参考和依据。.
