什么是心源性哮喘?
回答 Rekha Mankad, M.D.
心源性哮喘并不属于哮喘。它是伴随左心衰竭发生的咳嗽或哮鸣。取决于症状的严重程度,这种哮鸣可能成为一种医疗紧急情况。
心力衰竭可引发肺部积液,也就是被称为肺水肿的医疗状况。它还可能引发气道内和气道周围积液。这可能导致与哮喘症状相似的气短、咳嗽和哮鸣。
真的哮喘是由气道炎症引起的慢性疾病。炎症令气道变窄,导致呼吸困难。真哮喘与肺部积液或心脏病无关。
对二者进行明确区分非常重要,因为哮喘和心力衰竭的治疗方法不同。治疗心力衰竭可能有助于缓解心力衰竭和心源性哮喘的症状。过度使用急救吸入器等真哮喘的治疗方法,可能有害,而且可能导致症状恶化。
