Herzkranzgefäße

Herzkranzgefäße, also known as coronary arteries, are blood vessels that supply the heart muscle with oxygenated blood. They originate from the aorta, the main artery leaving the left ventricle of the heart. There are typically two main coronary arteries: the left coronary artery and the right coronary artery.

The left coronary artery branches into two smaller arteries, the left anterior descending artery and the left circumflex artery. The left anterior descending artery supplies the front of the left ventricle and the interventricular septum. The left circumflex artery supplies the side and back of the left ventricle. The right coronary artery usually supplies the right atrium, right ventricle, and the back wall of the left ventricle in many individuals.

These vessels are crucial for maintaining the heart's function. If the herzkranzgefäße become narrowed or blocked, often due to atherosclerosis (plaque buildup), it can lead to reduced blood flow to the heart muscle. This condition is known as coronary artery disease. Symptoms can include chest pain (angina), shortness of breath, and in severe cases, a heart attack (myocardial infarction). Maintaining healthy lifestyle choices is important for the health of the herzkranzgefäße.
