coronary thrombosis

Thrombosis is the formation of a clot or thrombus within the lumen of a blood vessel, obstructing the flow of blood through the circulatory system. Thromboembolism is a general term describing both thrombosis and its main complication which is embolisation.When a thrombus occupies more than 75% of surface area of the lumen of an artery, blood flow to the tissue supplied is reduced enough to cause symptoms because of decreased oxygen (hypoxia) and accumulation of metabolic products like lactic acid. More than 90% of obstruction can result in anoxia, the complete deprivation of oxygen, and infarction, a mode of death of cells.
