The coronary arteries
surround the entire surface of the heart and their role is to vascularize the cardiac muscle
. There are two of them and they originate from the aorta
. They are then divided into different branches to irrigate the entire heart. The drop in the size of the coronary artery
indicates heart failure
and leads to an angina
, or angora and is recognized by thoracic pain
. A myocardial infarction
is due to the obstruction of a branch of the coronary arteries leading to pain in the myocardial muscle. In this case, an examination of the coronary arteries called a coronarography is done after injecting a product which enables the precise localization of the artery in question and an intervention is made to re-establish adequate circulation.
