Coronary arteries

    Two arteries that come from the aorta to provide blood to the heart muscle.

RELATED TERMS
--------------------------------------

Arteries
Blood vessels that carry blood away from the heart to the arms, legs, head, body and organs.

Aorta
The largest artery in the body and the primary blood vessel leading from the heart to the body.

Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.

Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.

Muscle
Tissue made up of bundles of long, slender cells that contract when stimulated.

Corona Regional Medical Center
The Corona Regional Medical Center is a hospital in Corona, California, United States.

Coronal
A coronal plane through the body is a vertical plane from head to foot and parallel to the shoulders.

Coronary angiography
"The most accurate method (the ""gold standard"") for evaluating and defining coronary artery disease (CAD). Coronary angiography is used to identify the exact location and severity of CAD. "

Coronary Angiography (Cardiac Catheterization)
A procedure that allows picture to be taken of the arteries supplying the heart with blood (the coronary arteries). Angiography shows blockages in the arteries.

Coronary artery brachytherapy
Local radiation treatment within an artery to the heart. Coronary artery brachytherapy has been used to reduce the recurrence of blockage (obstruction) of a coronary artery after successful treatment of a blockage of a stent. A stent is a tubular structure that is implanted inside of a coronary artery to keep it open, thereby preventing a heart attack.

Coronary artery bypass graft
Abbreviated CABG. A form of bypass surgery that can create new routes around narrowed and blocked coronary arteries, permitting increased blood flow to deliver oxygen and nutrients to the heart muscle. CABG is an option for selected groups of patients with significant narrowings and blockages of the heart arteries. The bypass graft for a CABG can be a vein from the leg or an inner chest-wall artery. CABG surgery is one of the most commonly performed major operations. Coronary artery disease develops because of hardening of the arteries (atherosclerosis) that supply blood to the heart muscle. Diagnostic tests prior to (and after) CABG include the electrocardiogram (EKG), stress test, echocardiogram, and coronary angiography.

Coronary artery bypass graft (CAB or CABG)
A surgical procedure in which a healthy blood vessel is transplanted from another part of the body into the heart to replace or bypass a diseased vessel.

Coronary artery disease
A major cause of illness and death, coronary artery disease (CAD) begins when hard cholesterol substances (plaques) are deposited within a coronary artery.

Coronary Artery Disease (atherosclerosis)
A build-up of fatty material in the wall of the coronary artery that causes narrowing of the artery.

Coronary artery spasm
A sudden closing of an artery, which cuts off blood flow to the heart and causes symptom of angina or heart attack.

Coronary bypass
A bypass of a plaque within a coronary artery using part of a vein as a graft.

Coronary Disease
Damage to the heart. Not enough blood flows through the vessels because they are blocked with fat or have become thick and hard; this harms the muscles of the heart. People with diabetes are at a higher risk of coronary disease.

Coronary heart disease
A condition in which the coronary arteries narrow from an accumulation of plaque (atherosclerosis) and cause a decrease in blood flow.

Coronary Heart Disease
An imbalance between myocardial functional requirements and the capacity of the coronary vessels to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.

Coronary insufficiency
Insufficient blood flow through one or more coronary arteries.

Coronary Internal Mammary Artery Anastomosis
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.

Coronary occlusion
An obstruction of one of the coronary arteries that decreases flow to the heart muscle.

Coronary Occlusions
An imbalance between myocardial functional requirements and the capacity of the coronary vessels to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.

Coronary Prone Personality
Established behavior pattern characterized by excessive drive and ambition, impatience, competitiveness, sense of time urgency, and poorly contained aggression.

Coronary Reperfusion
Generally, restoration of blood supply to heart tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. Reperfusion can be induced to treat ischemia. Methods include chemical dissolution of an occluding thrombus, administration of vasodilator drugs, angioplasty, catheterization, and artery bypass graft surgery. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing MYOCARDIAL REPERFUSION INJURY.

Recurrent narrowing or constriction of a coronary artery following surgical procedures performed to alleviate a prior obstruction.

Coronary Restenosis
Recurrent narrowing or constriction of a coronary artery following surgical procedures performed to alleviate a prior obstruction.

Coronary Spasm
During coronary spasm, the coronary arteries restrict or spasm on and off, causing lack of blood supply to the heart muscle. It may occur at rest and can even occur in people without significant coronary artery disease.

Coronary Stenoses
Narrowing or constriction of a coronary artery.

Coronary Thromboses
