慢性阻塞性肺疾病预后因素和死亡预测因子

慢性阻塞性肺疾病（chronic obstructive pulmonary disease, COPD）是一种人类的主要慢性疾病和死亡病因，目前已上升为人类致死病因的第四位。据预测在未来10年中COPD的发病率和致死率将进一步增高。近年来，许多有关的预后和死亡预测因子的众多指标成为目前国内外研究的热点，但由于不同研究者所采取的研究方式和角度不同，所得出的结论并不完全一致。以下即对各观点作一简要综述。

Predictors of prognosis and mortality in chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease(COPD) is a significant worldwide chronic disease of human beings, which has become the fourth leading cause of death.
