由于慢性支气管炎(以下简称“慢支”)病程一般经过冗长,病变进展情况亦较复杂,特别是随着病情的演变常与肺气肿、肺心病相关联;且肺心病时常伴有肺气肿,而肺心病的病因80％是慢支。故对慢支、肺气肿、肺心病相互间之关系和发展规律的阐明对慢支的防治是很重要的,本文着重探讨慢支与肺气肿相互关系的病理研究进展。 As chronic bronchitis (hereinafter referred to as “chronic bronchitis”) generally long after the course of disease progression is also more complicated, especially with the evolution of the disease often associated with emphysema, pulmonary heart disease; and pulmonary heart disease often accompanied by lung Swollen, while the cause of pulmonary heart disease is 80% of chronic bronchitis. Therefore, chronic bronchitis, emphysema, pulmonary heart disease and the relationship between the law of development and clarification of the prevention and treatment of chronic bronchitis is very important, this paper focuses on the pathophysiology research on the relationship between chronic bronchitis and emphysema.
