A coronary occlusion, or coronary artery disease, is the partial or complete obstruction of blood flow in a coronary artery. This condition was first discussed in 1910 by Sir William Osler . [ 1 ] This condition slows or blocks the supply of oxygen-rich blood to the heart . [ 2 ]
Normally, the blockage should affect approximately 70% of the artery for symptoms to become noticeable. [3] Symptoms can be less severe during gradual narrowing, as this allows time for the widening of existing vessels and the formation of new ones ( collateral vessels ), allowing blood to still reach the area.
In approximately 33% of individuals, the left coronary artery gives rise to the posterior descending artery [4] which perfuses the posterior and inferior walls of the left ventricle. Sometimes a third branch is formed at the fork between left anterior descending and left circumflex arteries, known as a ramus or intermediate artery .
The animation shows plaque buildup or a coronary artery spasm can lead to a heart attack and how blocked blood flow in a coronary artery can lead to a heart attack. The most common cause of a myocardial infarction is the rupture of an atherosclerotic plaque on an artery supplying heart muscle.
The diagnosis of microvascular angina (previously known as cardiac syndrome X – the rare coronary artery disease that is more common in females, as mentioned, is a diagnosis of exclusion. Therefore, usually, the same tests are used as in any person suspected of having coronary artery disease: [75] Intravascular ultrasound
Coronary vasospasm may result in cardiac arrhythmias, altering the heart's electrical conduction with a risk of complete cardiac arrest from severe or prolonged rhythm changes. Mechanical abnormalities with an associated risk of cardiac arrest may arise from coronary artery dissection, which can be attributed to Marfan Syndrome or trauma. [29]

The circumflex artery arises from the left coronary artery and follows the coronary sulcus to the left. Eventually, it will fuse with the small branches of the right coronary artery. The larger left anterior descending artery (LAD), is the second major branch arising from the left coronary artery. It follows the anterior interventricular sulcus ...
