以胸痛为主诉的支气管哮喘26例临床分析

目的 探讨以胸痛为主要表现的支气管哮喘（简称哮喘）的临床特点与诊断要点。方法 在不明原因的胸痛患者当中通过支气管激发试验筛查哮喘患者，通过诊断性治疗确立哮喘诊断，分析患者的临床特点。结果 62例不明原因的胸痛患者中，经支气管激发试验、诊断性治疗并排除其他疾病，26例诊断为支气管哮喘。患者均以程度不等的胸痛为主要表现，22例（84．62％）同时有轻微的胸闷、气紧和咳嗽等症状，15例胸痛发作的诱因与哮喘常见诱因相同。规范治疗后所有患者胸痛症状均完全或部分缓解。结论 胸痛是哮喘的一种特殊临床表现，以胸痛为主诉的哮喘在临床上易被误诊，应通过支气管激发试验，结合治疗反应并排除其他疾病进一步确诊。
