Koronaararterid

Koronaararterid refers to the coronary arteries, which are blood vessels responsible for supplying oxygenated blood to the heart muscle itself. These arteries originate from the aorta, the main artery carrying blood from the left ventricle of the heart. The two main coronary arteries are the left main coronary artery and the right coronary artery.

The left main coronary artery quickly branches into two major arteries: the left anterior descending artery and the left circumflex artery. The left anterior descending artery supplies blood to the front and bottom of the left ventricle and the front of the septum. The left circumflex artery supplies blood to the left atrium and the back and side of the left ventricle. The right coronary artery typically supplies blood to the right atrium, the right ventricle, and the SA and AV nodes.

Diseases affecting the coronary arteries, collectively known as coronary artery disease (CAD), are a leading cause of heart attacks. The most common cause of CAD is atherosclerosis, a condition where plaque builds up inside the arteries, narrowing them and restricting blood flow. This plaque can rupture, leading to the formation of a blood clot that can completely block the artery, causing a heart attack. Risk factors for CAD include high blood pressure, high cholesterol, diabetes, smoking, obesity, and a family history of heart disease.
