Objective: To explore the causes of common misdiagnosis of cough variant asthma (CVA) and to improve the early diagnosis of cough variant asthma. Methods: The clinical data of 128 CVA patients from 2004-06 / 2009-05 were retrospectively analyzed. Results: Of the 128 patients with CVA, 79 were newly diagnosed, 49 were misdiagnosed, and the rate of misdiagnosis was 38.3%. Conclusion: CVA is a special type of asthma. It is one of the common causes of chronic cough. Its clinical features are lack of specificity and the rate of misdiagnosis is high. Early diagnosis of CVA is of great significance for the treatment of asthma and prevention of asthma.
