Introduction
The coronary arteries originate from the ascending aorta and are among the major arteries arising from the left ventricle. In daily life, it is important to maintain a healthy lifestyle, including balanced nutrition, moderate exercise, smoking cessation, and limiting alcohol consumption, which helps prevent and reduce the occurrence of coronary artery disease. If any physical discomfort occurs, prompt medical attention at a hospital is recommended.
The coronary arteries originate from the ascending aorta and are among the main arteries arising from the left ventricle. Specifically:
The ascending aorta is one of the primary arteries emerging from the left ventricle. After giving off the brachiocephalic artery and the left common carotid artery, it divides into the left and right coronary arteries, which supply blood to the myocardium on the left and right sides of the heart, respectively. The coronary arteries are major vessels responsible for delivering oxygenated blood to the myocardial tissue. Originating from the ascending aorta, they supply most regions of the heart, including the anterior wall, lateral wall, posterior wall, and apex, thus ensuring normal metabolism and physiological function of cardiac muscle cells. If abnormalities or diseases occur in the coronary arteries—such as atherosclerosis, luminal narrowing, or occlusion—blood flow may be impaired, potentially leading to cardiovascular diseases.
In daily life, maintaining a healthy lifestyle—including balanced nutrition, moderate exercise, smoking cessation, and limiting alcohol consumption—can help prevent or reduce the risk of coronary artery disease. If any physical discomfort occurs, prompt medical evaluation at a hospital is recommended.
