koronarterie

The koronare Arterie, commonly referred to as the coronary arteries, are the major blood vessels that supply blood to the heart muscle itself. These arteries arise from the aorta, the largest artery in the body, and divide into two main branches: the anterior descending artery and the circumflex artery.

The left main coronary artery, a short vessel that originates from the left side of the aorta, gives off the anterior descending artery, which then gives off the diagonal and marginal branches, supplying blood to the anterior wall of the left ventricle and to the anterior two-thirds of the interventricular septum. The circumflex artery, originating from the left main coronary artery, circles around the heart and supplies the lateral and posterior walls of the left ventricle and the mitral valve.

The right coronary artery is the first branch of the aorta and it supplies the right atrium, the right ventricle, and the sinutubular junction, which is part of the atrioventricular valve. In the majority of people, the right coronary artery continues as the posterior descending artery, which then supplies blood to the inferior surface of the heart.

Compromise of the coronary arteries can result in myocardial ischemia. Risk factors for coronary artery disease include atherosclerosis, high blood pressure, high cholesterol levels, smoking, diabetes, and a family history of heart disease. Regular check-ups and preventive measures are essential to maintaining the health and function of the coronary arteries.

The anatomy of the coronary arteries can be relevant in the diagnosis and treatment of various heart conditions.
