This circulation of blood is called the coronary circulation.

Disorders of the coronary circulation can have devastating effects to the heart since damage to the heart can reduce coronary circulation which causes further damage.

; Coronary heart disease: Coronary heart disease is a general term for any reduction in coronary circulation.

; Myocardial infarction ( aka heart attack ): A myocardial infarction is the death of a part of the heart which is typically caused by a blockage of the coronary circulation or coronary heart disease.

; Restenosis: Recurrence of stenosis which would refer to a coronary artery in the context of the coronary circulation.

In 1242 Ibn al-Nafis gave the first description of pulmonary circulation and coronary circulation.

The heart is fed by the coronary circulation and is enclosed by a sac known as the pericardium ; it is also surrounded by the lungs.

* 1242 — Ibn al-Nafis publishes his Commentary on Anatomy in Avicenna's Canon, in which he discovers the pulmonary circulation and coronary circulation, which form the basis of the circulatory system.

* 1242 – Ibn an-Nafis suggests that the right and left ventricles of the heart are separate and discovers the pulmonary circulation and coronary circulation

A coronary angiogram ( an X-ray with radio-opaque contrast in the coronary arteries ) that shows the left coronary circulation.

Upon formation, intraluminal thrombi can occlude arteries outright ( i. e. coronary occlusion ), but more often they detach, move into the circulation and eventually occlude smaller downstream branches causing thromboembolism ( i. e. Stroke is often caused by thrombus formation in the carotid arteries ).

The healthy epicardial coronary artery consists of three layers, the intima, media, and adventitia.

The coronary arteries were sclerotic and diffusely narrowed throughout their courses, and the right coronary artery was virtually occluded by a yellow atheromatous plaque 1.5 cm. distal to its origin.

The intima of the larger coronary arteries was thickened by fibrous tissue containing fusiform clefts and mononuclear cells.

With meat, milk, butter and ice cream, the calorie-heavy U.S. diet is 40% fat, and most of that is saturated fat -- the insidious kind, says Dr. Keys, that increases blood cholesterol, damages arteries, and leads to coronary disease.

In fact the smooth muscle within the abdominal aorta is derived from mesoderm, and the coronary arteries, which arise just above the semilunar valves, possess smooth muscle of mesodermal origin.

In vitro, they dilate the coronary and peripheral arteries and have negative inotropic and chronotropic effects-decreasing afterload, improving myocardial efficiency, reducing heart rate and improving coronary blood flow.

; Percutaneous coronary intervention ( PCI ): Procedures to treat stenotic coronary arteries by accessing through a blood vessel.

; Coronary catheterization: Catheterization of the coronary arteries.

In his correspondence with Heberden, he wrote, " How much the heart must suffer from the coronary arteries not being able to perform their functions.

He underwent a cardiac catheterization and two stents were inserted into one of his coronary arteries, which had become 90 % blocked.

Armstrong died in Cincinnati, Ohio, at the of age 82, on August 25, 2012, of complications from blocked coronary arteries.

The very first branches off of the aorta are the coronary arteries, which supply blood to the heart muscle itself.

With the advent of subsecond rotation combined with multi-slice CT ( up to 320-slices ), high resolution and high speed can be obtained at the same time, allowing excellent imaging of the coronary arteries ( cardiac CT angiography ).

Many researchers advance the belief that oxidative modification of LDL-cholesterol ( sometimes called " bad " cholesterol ) promotes blockages in coronary arteries that may lead to atherosclerosis and heart attacks.

* Coronary disease – interference with the heart's blood supply, typically by clogging of coronary, or other, arteries.

An autopsy determined that the cause of death was a 90-percent blockage in two coronary arteries.

Ischaemic or ischemic heart disease ( IHD ), or myocardial ischaemia, is a disease characterized by ischaemia ( reduced blood supply ) of the heart muscle, usually due to coronary artery disease ( atherosclerosis of the coronary arteries ).

If part of the heart seems to receive an insufficient blood supply, coronary angiography may be used to identify stenosis of the coronary arteries and suitability for angioplasty or bypass surgery.

The coronary veins all empty into the coronary sinus which empties into the right atrium.

Arteries or veins from elsewhere in the patient's body are grafted to the coronary arteries to bypass atherosclerotic narrowings and improve the blood supply to the coronary circulation supplying the myocardium ( heart muscle ).

Typically, the left internal thoracic artery ( LITA ) ( previously referred to as left internal mammary artery or LIMA ) is grafted to the left anterior descending artery and a combination of other arteries and veins is used for other coronary arteries.

Typically 3 – 8 cc of the radiocontrast agent is injected for each image to make the blood flow visible for about 3 – 5 seconds as the radiocontrast agent is rapidly washed away into the coronary capillaries and then coronary veins.

The remaining blood from the esophagus is drained into the superficial veins lining the esophageal mucosa, which drain into the left gastric vein ( coronary vein ), which in turn drains directly into the portal vein.

What concerns him much more is the relationship of diet to the nation's No. 1 killer: coronary artery disease, which accounts for more than half of all heart fatalities and kills 500,000 Americans a year -- twice the toll from all varieties of cancer, five times the deaths from automobile accidents.

Explains Keys: As the fatty protein molecules travel in the bloodstream, they are deposited in the intima, or inner wall of a coronary artery.

During World War 2,, doctors in The Netherlands and Scandinavia noted a curious fact: despite the stresses of Nazi occupation, the death rate from coronary artery disease was slowly dropping.

Antioxidants are widely used in dietary supplements and have been investigated for the prevention of diseases such as cancer, coronary heart disease and even altitude sickness.

On February 11, 2010, he was rushed to Columbia Presbyterian Hospital in New York City after complaining of chest pains, and had two coronary stents implanted in his heart.

The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.

; Acute coronary syndrome ( ACS ): Acute coronary syndrome is a broad term encompassing many acute myocardial infarction symptoms.

Atherosclerosis of a coronary artery leads to coronary heart disease.
