Widowmaker Heart Attack

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 involves the left anterior descending artery, which supplies the largest part of your heart muscle.
A widowmaker heart attack happens when there's a blockage in the LAD, which supplies half of your heart muscle.

What is a widowmaker heart attack?

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.

How serious is a widowmaker heart attack?

A widowmaker heart attack is immediately life-threatening. This is because the LAD provides about 50% of your heart muscle’s blood supply.

Who does a widowmaker heart attack affect?

The name sounds like a widowmaker heart attack only affects men and people assigned male at birth (AMAB). However, women and people assigned female at birth (AFAB) can have this type of heart attack, too.

Heart attack risk increases when you:

  • Are older than age 45 for men and people AMAB.
  • Are older than age 50 for women and people AFAB.
  • Have a family history of heart disease.
  • Don’t have enough nutrition in your diet.
  • Use tobacco products.
  • Don’t exercise enough.
  • Have certain other medical conditions, such as obesity, high blood pressure and high cholesterol.

Management and Treatment

You may be in the hospital for two to four days after a widowmaker heart attack. Some people need to stay longer, especially if they have complications.

Complications/side effects of the treatment

Some drugs for a widowmaker heart attack can cause bleeding.

People who receive a stent to keep their LAD artery open need to take medicine to prevent blood clots.

A coronary artery bypass graft operation carries a risk of stroke, another heart attack or death.



How can I prevent a widowmaker heart attack?

You can reduce your risk of a widowmaker heart attack in many ways, such as:

  • Eating foods that don’t have saturated fats.

Outlook / Prognosis

What can I expect if I have a widowmaker heart attack?

You’ll need about eight weeks for widowmaker heart attack recovery. Some people can return to work in two weeks. Others need up to three months to recover. If your job is physically demanding, it may be helpful to change to a less demanding job.

Outlook for a widowmaker heart attack

Fifty percent of heart attack deaths happen in the first few hours after symptoms start. But many people who live several days after a heart attack can recover fully. However, 10% don’t make it through the first year after a heart attack.

Living With

How do I take care of myself?

If you’ve had a heart attack, you may need to make some changes in your life to prevent another one. You can:

When should I see my healthcare provider?

Be sure to go to all of your scheduled appointments with your healthcare provider. They’ll want to see how you’re progressing in your recovery. Appointments are also a way to learn if you need a different dose of any of the medicines you’re taking.

When should I go to the ER?

Call 911 or your local emergency number right away if you’re having symptoms of another heart attack.

What questions should I ask my doctor?

Questions you may want to ask your provider include:

  • How likely am I to have another heart attack?
  • What’s the best treatment for my situation?
  • Is there a support group for heart attack survivors?

A note from Cleveland Clinic

Calling for help right away is crucial if you think you’re having a heart attack. The faster you get help, the more heart muscle a provider may be able to save. Paramedics can start treating you while you’re on the way to the hospital, so call 911 instead of having a friend or relative drive you to the hospital.
