Encircling in the manner of a crown; a term applied to vessels; nerves, ligaments, etc. The term usually denotes the arteries that supply the heart muscle and, by extension, a pathologic involvement of them.
Surrounding, as a crown, especially the coronary arteries surrounding the heart.
“Crown-like” or “relating to a crown,” or “encircling.” In health care usage, “coronary” refers to the blood vessels of the heart, which encircle the heart and are called “coronary vessels.” A cardiac care unit is often called a “coronary care unit,” since most of the patients treated there suffer from problems of the circulation serving the heart muscle.
A term applied to several structures in the body encircling an organ in the manner of a crown. The coronary arteries are the arteries of supply to the heart which arise from the aorta, just beyond the aortic valve, and through which the blood is delivered to the muscle of the heart. Disease of the coronary arteries is a very serious condition, producing various abnormal forms of heart action and the disorder, angina pectoris.
Encircling, as the blood vessels that supply blood directly to the heart muscle; loosely used to refer to the heart and to coronary-artery disease. Coronary pain is usually dull and heavy and may radiate to the arm, jaw, shoulders, or back. Typically, the patient describes the pain as being viselike or producing a feeling of compression or squeezing of the chest.
A structure that encompasses another in a circular manner, resembling a crown, is referred to as a “corona.” This term is commonly used to describe the coronary arteries, which encircle the heart and provide it with the necessary blood supply. In nonmedical contexts, “corona” may also be used as a colloquial term for a heart attack.
