"All vessels converging in lung"theory is the summery of the interaction between lung and blood

lung and vessels

including the connotations of "the lung assisting the heart to move the blood"and "the lung governs management and regulation". Modern medicine research found that lung has closely correlation with angiocarpy. Clinical practice indicates that many kinds of lung diseases can cause ischemic heart disease（IHD）. Atherosclerosis（AS） is the primary pathological basis of IHD

which can be connected with the injury of lung tissues through systematic inflammation

oxidative stress

dysfunction of vessels

etc.

indicating the injury of lung can cause the dysfunction of blood and vessels in Chinese medicine. That means the "injury of lung"can easily lead to the "injury of heart"

and it proves the scientific connotation of "all vessels converging in lung"theory in traditional Chinese medicine

and is significant in developing the theory of visceral manifestation in traditional Chinese medicine and directing the prevention of IHD.
