The anterolateral heart wall is supplied by which coronary artery?

The anterolateral portion of the heart wall is primarily supplied by the left coronary artery. This artery branches into the left anterior descending artery and the left circumflex artery, which supply blood to different areas of the left side of the heart.

The left anterior descending artery typically supplies the anterior part of the interventricular septum and the anterior wall of the left ventricle, while the left circumflex artery generally supplies the lateral aspect of the left ventricle and the posterior wall in some individuals. Consequently, the left coronary artery is the primary source of blood supply for the anterolateral heart wall, making it critical for maintaining the function and health of that region.

Understanding coronary blood supply is essential in critical care, as ischemia in these areas can lead to significant cardiac complications.
