What happens if the left anterior descending artery is blocked?

What happens if the left anterior descending artery is blocked?

The widow-maker is a massive heart attack that occurs when the left anterior descending artery (LAD) is totally or almost completely blocked. The critical blockage in the artery stops, usually a blood clot, stops all the blood flow to the left side of the heart, causing the heart to stop beating normally.

How serious is a blockage in the LAD?

The total blockage of the LAD artery is a serious problem that requires immediate treatment. Delayed treatment for a heart attack can lead to significant tissue damage and scarring. It can be life threatening or lead to permanent disability. Not all heart attacks start with crushing chest pain or arm numbness.

Which coronary artery is most commonly blocked?

The LAD artery is the most commonly occluded of the coronary arteries. It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system.

How is LAD blockage treated?

Bypass surgery usually is the best choice for a blocked LAD. If the LAD is not blocked, and there are no other complicating factors, stents are more likely to be used, even if both of the other arteries are blocked.

What percentage of LAD blockage requires a stent?

By clinical guidelines, an artery should be clogged at least 70 percent before a stent should be placed, Resar said. “A 50 percent blockage doesn’t need to be stented,” he said.

Can you stent the LAD?

If the LAD disease is determined to be significant then a stent is often used to relieve the blockage. Sometimes bypass surgery is advised, and usually a vessel called the LIMA (left internal mammary artery) is used as the bypass vessel and is associated with very good long-term results.

Why is the LAD artery called the Widowmaker?

The LAD artery carries fresh blood into the heart so that the heart gets the oxygen it needs to pump properly. If it’s blocked, the heart can stop very fast — which is why this type of heart attack is called a “widowmaker.”

How long does a LAD stent last?

How long will a stent last? It is permanent. There is just a 2–3 per cent risk of narrowing coming back, and if that happens it is usually within 6–9 months. If it does, it can potentially be treated with another stent.

How long is bed rest after heart cath?

Time-in-bed standards vary widely, from 3 to 12 hours after cardiac catheterization to more than 24 hours of bed rest after angioplasty. Bed rest with restricted movement causes patient discomfort, increases nursing workload, and prolongs length of hospital stay.

Why is the LAD called the Widowmaker?

How do you detect a Widowmaker blockage?

Some of the warning signs and symptoms of a 100 percent LAD blockage include:

1. feeling chest pain or discomfort.
2. experiencing pain that radiates out into your arms, legs, back, neck, or jaw.
3. having pain in your abdominal area that feels like heartburn.
4. having muscle pain in your chest or neck that feels like a pulled muscle.
