Coronary thrombosis. Light micrograph (LM) of part of a thrombus (red) attached to the interior wall (purple) of the coronary artery of the heart. The fibrous clot,which is packed full of red blood cells,leucocytes and platelets,can prevent oxygen-carrying blood from reaching parts of the heart muscle. If the blood supply to a part of the heart is interrupted,the condition is know as acute myocardial infarction (AMI),or a heart attack,which damages the heart and is potentially fatal. Thrombi (clots) may also block arteries supplying the brain,legs,kidneys,and other areas of the body |
