koronarer

The term "koronarer" is the German adjective referring to the coronary arteries. These are blood vessels that supply the heart muscle, known as the myocardium, with oxygenated blood. The heart muscle requires a constant and sufficient supply of oxygen to function properly.

The coronary arteries originate from the aorta, the main artery carrying oxygenated blood from the left ventricle of the heart to the rest of the body. There are typically two main coronary arteries: the left main coronary artery and the right coronary artery. The left main coronary artery branches into two further arteries: the left anterior descending artery and the left circumflex artery.

Diseases affecting these arteries are collectively known as coronary artery disease. The most common form of coronary artery disease is atherosclerosis, a condition where plaque builds up inside the arteries, narrowing them and restricting blood flow. This narrowing can lead to angina, which is chest pain or discomfort caused by reduced blood flow to the heart muscle. If the plaque ruptures, it can cause a blood clot that completely blocks an artery, resulting in a myocardial infarction, commonly known as a heart attack. Medical interventions aim to restore blood flow to the heart muscle and prevent further damage.
