“A widowmaker heart attack happens when you have a blockage in the biggest artery in your heart. That means blood can’t move through your left anterior descending (LAD) artery, which provides 50% of your heart muscle’s blood supply. Immediate treatment is crucial for a chance at survival.

A widowmaker heart attack is a type of heart attack in which you have a full blockage in your heart’s biggest artery. This artery, the left anterior descending (LAD) artery, sends oxygen-rich blood to your heart’s left ventricle. This lower chamber pumps oxygen-rich blood to your aorta, which sends it to your body.

Healthcare providers call a heart attack a “myocardial infarction,” which means you don’t have enough blood going to your heart muscle (myocardium). Your heart muscle can die without enough blood flow.

A heart attack is a medical emergency. Call 911 or your local emergency number if you think you’re having a heart attack.”
