LAD most often means the **left anterior descending coronary artery**, one of the main arteries that supplies blood to the heart muscle. It runs on the front surface of the heart and gives off branches that nourish the left ventricle. Clinicians commonly mention LAD in discussions of **coronary artery disease**, heart attacks, stents, and bypass surgery. In some contexts, LAD can also mean **left axis deviation** on an ECG, but this article focuses primarily on the coronary artery meaning.
