—Structures that encircle another structure (such as the coronary arteries, which encircle the heart); commonly used to refer to a coronary thrombosis or a heart attack
Coronary means belonging or relating to the heart. If all the coronary arteries are free of significant obstructions, all parts of the heart will receive equal amounts of oxygen
If someone has a coronary, they collapse because the flow of blood to their heart is blocked by a large lump of blood called a clot. = heart attack. relating to the heart = cardiac (coronarius , from corona ( CROWN); because the blood-tubes coming out of the top of the heart look like a crown). coronaries if someone has a coronary, their heart suddenly stops working because the flow of blood to it has been blocked by a small piece of solid blood = heart attack
