The left coronary artery is one of the two main arteries that supply blood to the heart. It branches off from the aorta and divides into two primary branches: the left anterior descending artery and the circumflex artery. These branches provide oxygen-rich blood to the heart muscle, ensuring it functions effectively. This artery plays a crucial role in maintaining heart health. Blockages or narrowing in the left coronary artery can lead to serious conditions, such as angina or myocardial infarction (heart attack). Regular check-ups and a healthy lifestyle can help keep this artery functioning properly.
