The Left Anterior Descending Artery (LAD) is a major blood vessel that supplies oxygen-rich blood to the front part of the heart. It branches off from the Left Coronary Artery and runs down the anterior interventricular sulcus. The LAD is crucial for the heart's function, as it nourishes the left ventricle and parts of the septum. Blockages in the LAD can lead to serious heart conditions, such as a heart attack. This artery is often referred to as the "widowmaker" because significant blockages can be life-threatening. Maintaining heart health is essential to prevent issues related to the LAD.
