| | Coronary circulation - Wikipedia, the free encyclopedia |
 | | These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the heart muscle. | | | As a result most myocardial perfusion occurs during heart relaxation (diastole) when the subendocardial coronary vessels are patent and under low pressure. | | | The exact anatomy of the myocardial blood supply varies considerably from person to person. |

| | Coronary artery bypass graft surgery creates new pathways around the areas of your blocked arteries, allowing blood flow to be restored. | | | Blood and oxygen may no longer flow easily to the heart muscle which may cause angina (pain, discomfort or pressure in the chest that is caused by an insufficient supply of blood to the heart). | | | Once coronary artery surgery has been recommended and scheduled by your cardiac surgeon, you will be admitted the day of or day before your surgery. |

| | Coronary thrombosis (heart attack) |
| | After suffering from coronary thrombosis, a scar will develop in the heart muscle and this part of the muscle will function less well. | | | Most commonly a coronary thrombosis will cause severe chest pains behind the sternum (breast bone), often radiating towards the left arm. | | | At the hospital they can decide whether it is a myocardial infarction (coronary thrombosis), severe angina (chest pains) or possibly something completely different. |

| | The heart muscle is nourished by a system of arteries which arise from the aorta: the right and left coronary arteries. | | | In order for the heart to work, the heart muscle must receive blood of its own. | | | These two main arteries lie on the surface of the heart and divide into smaller branches which extend to the back. |

| | Coronary artery disease (CAD) is the most common form of heart disease and top cause of death in the United States. | | | This condition occurs when the coronary arteries, the blood vessels that supply oxygen-rich blood to your heart muscle, gradually become narrowed or blocked by plaque deposits. | | | The plaque deposits decrease the space through which blood can flow. |
