Thrombosis / Coronary Thrombosis
The occlusion or blockage of blood flow within a vessel caused by blood that has clotted within the vessel. Coronary thrombosis is a term used to describe the blockage of a coronary artery secondary to blood clotting within the artery.
Thrombosis of coronary arteries occurs when the opening, or lumen, of the artery becomes so small that the blood flow through the narrowed segment slows, allowing the blood to clot in the artery. Thrombosis of a coronary artery can lead to a heart attack if not treated.
