An obstruction to blood flow in the pulmonary artery leading to increased pressure on pulmonary heart (as the blood in the pulmonary artery is a question of right heart failure). This leads to acute right ventricular failure
Blockage of the pulmonary artery can cause a reflex discharge in the blood of biologically active substances under the action of which there is a narrowing of vessels (called vasoconstrictors)
Recurrent pulmonary embolism leads to the development of such diseases as pulmonary heart
Violation of the enrichment process oxygen and return carbon dioxide, resulting in a deteriorating security tissues and organs of oxygen
