长期慢性肺部疾患所致的胸廓畸形,或肺血管性病变影响了小循环的调节功能而加重了右心的负担所引起的心脏病,统称为慢性肺原性心脏病。伍德(Wo-od)氏又将其分为二类:其原发病因在肺组织的,例如阻塞性肺气肿、普遍性肺纤维化病变、肺尘埃沉着症、先天性肺囊肿、严重的支气管扩张症及严重的胸廓与脊椎畸形等所引起的,称为慢性缺氧血性肺原性心脏
Long-term chronic lung disease caused by thoracic deformity, or pulmonary vascular disease affected the regulation of small circulation and increased the burden of right heart caused by heart disease, collectively referred to as chronic pulmonary heart disease. It is divided into two categories by Wo-od: its primary cause is in lung tissue, such as obstructive pulmonary emphysema, generalized pulmonary fibrosis, pneumoconiosis, congenital pulmonary cysts, severe Bronchiectasis and severe thoracic and spine caused by deformities, known as chronic anoxemic pulmonary heart
