The Left Coronary Artery (LCA) 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 (LAD) and the Left Circumflex Artery (LCX). These branches provide oxygen-rich blood to the left side of the heart, which is crucial for its pumping function. The LCA plays a vital role in maintaining heart health. Blockages or narrowing in this artery can lead to serious conditions such as angina or myocardial infarction (heart attack). Therefore, understanding the LCA's function is essential for cardiovascular health.
