心肺两个重要器官紧密相连,相互影响,肺的呼吸功能不仅取决于肺本身的功能状态,并且受血液循环的影响,而心脏的活动功能又与肺的呼吸循环状态有关。故某些呼吸系统疾病往往能引起心血管一系列生理病理改变。一、慢性阻塞性肺疾患的心血管表现慢性阻塞性肺疾患(COPD)通常指慢性支气管炎和肺气肿,在美国每年至少有5万死者与COPD有关,尸检证明罹患此病的10％—40％有慢性肺心病。从呼吸系原发病发展到肺心病,需要较长时间,一般6年到10年,多发在中年以上。
Heart and lung are closely linked to two vital organs, affecting each other. The respiratory function of the lung depends not only on the functional status of the lung itself, but also on the circulation of the lung, which is also related to the respiratory cycle of the lung. Therefore, some respiratory diseases often cause a series of cardiovascular physiological and pathological changes. First, the cardiovascular manifestations of chronic obstructive pulmonary disease Chronic obstructive pulmonary disease (COPD) usually refers to chronic bronchitis and emphysema in the United States each year at least 50,000 dead with COPD, autopsy proved that suffering from 10% of the disease - 40% have chronic pulmonary heart disease. From the onset of primary respiratory disease to pulmonary heart disease, takes a long time, usually 6 years to 10 years, multiple in middle age.
