Asthma remains a frightening diagnosis with an unclear prognosis and outcome. The estimated global burden of asthma is substantial¹ and reductions in mortality from asthma have stalled since 2006, with wide variations between countries.² Causes are multifactorial, triggers and symptoms are varied, and the disease course over a lifetime is unpredictable. Severity can fluctuate with sudden asthma attacks leading to death in previously well controlled patients or those with very few symptoms on no medication.

哮喘之后：气道疾病需要重新命名和一场革命

哮喘仍然是令人恐惧的诊断，预后和结果尚不清楚。自2006年以来，估计的全球哮喘病负担是巨大的¹，哮喘死亡率的降低一直停滞不前，各国之间差异很大。²原因是多因素的，触发因素和症状是多种多样的，并且一生中的病程是无法预测的。严重程度会随着突然的哮喘发作而波动，导致先前控制良好的患者或没有药物就很少症状的患者死亡。
