慢性阻塞性肺疾病(COPD)是以不完全可逆的气流受限为特征的呼吸系统疾病,吸烟是COPD发生、发展的高危因素,烟草中的有害物质降低了气道的防御功能,使炎症细胞浸润,致支气管黏膜充血、水肿,管腔发生结构性变化,活动耐力下降,严重影响患者的生活质量。所以,戒烟是预防COPD的主要治疗手段。本文通过对44例COPD吸烟患者进行为期1年的戒烟干预,并追踪其临床症状、体征及肺功能的变化,效
Chronic Obstructive Pulmonary Disease (COPD) is a respiratory disease characterized by incompletely reversible airflow limitation.
