Three major coronary arteries provide the heart with oxygenated blood, the right coronary artery (RCA), the left coronary artery (LCA) and the circumflex artery (Cx). When the coronary arteries are affected by atherosclerosis and the lumen of the coronary arteries narrows, the heart receives less oxygenated blood and becomes hypoxic, which results in angina pectoris. | Three major coronary arteries provide the heart with oxygenated blood, the right coronary artery (RCA), the left coronary artery (LCA) and the circumflex artery (Cx).
