's general knowledge of dangerous factor of the artery high pressure of lung
1,Disease of connective tissue: The intersection of connective tissue and disease the intersection of lung and the intersection of artery and very much important cause of disease of high pressure ' Account for 10%-50%) ,Nearly all diseases of connective tissue can erupt the artery high pressure of lung simultaneously, overall incidence is about 2%, can sometimes store in alone, can also accompany and take place quality disease among the lung and exist, meet more with women.
2,Door pulse and high pressure and hepatopathy: Chronic hepatopathy and door pulse and high pressure are apt the artery high pressure of lung happens, about 2%-4% of incidence. It is not so obvious that it is machine-processed that it happens, may shunt, make lung by door - body blood flow volume increase and shrink material by blood vessel that liver remove under the normal situation and blood vessel proliferate the material enter the lung to circulate directly, make the intersection of lung and the intersection of blood vessel and shrink and door venous embolism, thus produced the artery high pressure of lung.
3,HIV infects: In HIV the infeted, with the artery high pressure of lung more incident of drug addict of intravenous injection medicine, account for 42%-56%, perhaps its reason and intravenous injection, it cause lung artery thromboembolism to have something to do that foreign matter enters blood circulation, with infecting at the same time ' Such as virus hepatitis) , hepatopathy, the intersection of door and the intersection of pulse and high pressure,etc. concern certainly too. Mechanism it take place it is may HIV through against lasting virus and lasting mediums relevant ( For instance cell factor and growth factor) Release, activate macrophages and lymphocytes, cause the artery high pressure of lung.
4,The appetite inhibits medicines: Take the intersection of Amy and the intersection of thunder and department, the intersection of Fluorine and the intersection of benzene and the intersection of third amine,etc. and appetite, inhibit medicines from might lead to the fact the artery high pressure of lung, its mechanism may be: Impel blood platelet 5 the intersection of hydroxy and the intersection of color and the intersection of amine and release, inhibit 5 the intersection of hydroxy and the intersection of color and uptake again of amine, make the intersection of circulation and blood dissociate, increase by 5 the intersection of hydroxy and the intersection of color and amine density. And lung blood vessel smooth muscle cell hyperplasia that free 5 hydroxy color amine makes the lung blood vessel shrink with strength, and gather through promoting the blood plateletting makes the lung circulate thrombosis of some little circulation, thus bring about the artery high pressure of lung in some hereditary susceptible persons.
5,Gender: The sending high-pressure incidence of lung artery is male 2 times, specially the sending artery high pressure of lung is seen in reproduction age women more.
6,The spleen is excised: Spleen excise patient take place the intersection of lung and the intersection of artery and dangerous increase of high pressure, spleen excise get lung time interval that artery diagnosed under high pressure 4-32 since. Reason its, perhaps because after spleen excise, spleen filter remove unusual function of erythrocyte, lose, the unusual erythrocyte that the blood circulation is held up in in midium or long term activates the blood platelet, it causes skin damaging, thrombosis in the blood vessel in the lung blood vessel bed that the latter assembles. Spleen excise take place the intersection of lung and the intersection of artery and the intersection of lung and the intersection of artery and pathology of high pressure person change and specially artery high pressure similar lung of taking place etc., shown as the lung artery membrane fiber, clump damage and occur frequently the thrombosis in the lung arterioled.
7,Dissolve courageous and upright anaemia: Dissolve about 20%-40% of high-pressure incidence of lung artery of courageous and upright anaemia.
8,Tubercle: The artery high pressure of lung can happen to 5.7% of the tubercle patients, and the dangerous increase of the artery high pressure of lung happens with reduction of the lung capacity.
9,Lung artery high pressure suffer from factor, include thyroid gland disease, starch kind change also while being apt while being other, chronic nephropathy, hemoglobin if ill rare genetic disease store up disease, lipid store up obstacle and heredity person who bleed capillary expand disease,etc. while being glycogenic while being 1 type.
