A widowmaker heart attack involves a full blockage of the largest artery in your heart. Despite the name, this type of heart attack isn’t always fatal, but quick treatment is key.
A widowmaker heart attack is a type of heart attack that’s caused by a 100 percent blockage of the left anterior descending (LAD) artery. It’s also sometimes referred to as a chronic total obstruction (CTO).
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.”
But the widowmaker isn’t always fatal. Let’s take a closer look at how to know when one might be coming, what can cause it, and what treatment and recovery are like after you’ve had one.
The symptoms of a widowmaker are essentially the same as those of any type of heart attack. And as with other heart attacks, you may not notice any symptoms until the heart attack begins (and sometimes not even then).
Seek emergency medical attention immediately if you have any heart attack symptoms. Some of the warning signs and symptoms of a 100 percent LAD blockage include:
- feeling chest pain or discomfort
- experiencing pain that radiates out into your arms, legs, back, neck, or jaw
- having pain in your abdominal area that feels like heartburn
- having muscle pain in your chest or neck that feels like a pulled muscle
- having difficulty breathing
- feeling anxious or panicky for no apparent reason
- feeling dizzy, lightheaded, or disoriented
- getting sweaty without warning
- feeling sick
- throwing up
- feeling like your heart is skipping beats
A widowmaker heart attack is caused by a complete block of the left anterior descending (LAD) artery. The LAD transports a large amount of blood into your heart, so without blood passing through the LAD, your heart can quickly run out of oxygen and stop beating.
Plaque can cause blood clots that obstruct the artery. In some cases, the clots can build up quickly and instantly cause a 100 percent blockage even if your LAD was only partially blocked.
The risk factors for a widowmaker heart attack, as with any heart attack, are primarily
Some of the lifestyle risk factors for a widowmaker heart attack include:
- smoking cigarettes or chewing tobacco regularly
- being overweight or obese
- having a diet that’s not healthy for your heart, which includes high amounts of processed grains, unhealthy fats, full-fat dairy, and sodium
- having high blood pressure
- having high amounts of low-density lipoprotein (LDL or “bad” cholesterol) in your blood
- having low amounts of high-density lipoprotein (HDL or “good” cholesterol) in your blood
- having diabetes or prediabetes
- not getting enough exercise
Genetic factors that can make you more vulnerable to a heart attack or other heart conditions include:
- Race. You’re
more likelyto have a heart attack if you’re of European, African-American, or Native American descent.
- Genetic conditions. Certain (often rare) conditions are passed through a single gene (called monogenic conditions) that can increase your risk for a heart attack. These can include hypertrophic cardiomyopathy a hypercholesterolemia. In some cases, conditions caused by multiple gene variants (called polygenic conditions)
make you more vulnerable, such as dyslipidemia.
Head straight to the emergency room if you’re having symptoms of a heart attack. The more quickly a widowmaker is addressed and treated, the higher your chance of recovery.
The most common emergency treatment for a 100 percent LAD blockage consists of the following steps:
- Your doctor inserts a catheter through a small cut in your leg or groin area.
- The catheter is directed through your LAD and a small balloon on the catheter’s end is inflated to help clear the blockage. These first two steps are called angioplasty.
- Your doctor inserts a stent, a small metal tube made of tiny meshed wires, to help keep your LAD open so that blood can pass through and continue restoring oxygen to your heart muscles.
Your doctor may insert a long-term stent to prevent the artery from getting clogged again. Some of these remain in the artery permanently, but other may be designed to dissolve over time so that your artery returns to a normal state.
Based on your recovery from the heart attack, your doctor may suggest heart surgery. You may also need heart surgery if your doctor finds blockages in multiple arteries around your heart.
Some surgery options include:
- Atherectomy. This is exactly like an angioplasty except that the catheter has tiny, rotating blades to clear away plaque buildup.
- Bypass. Your doctor uses healthy veins or arteries from other parts of your body to move the blood through a new blood vessel around the blockage.
- Valve replacement. Your doctor uses a healthy heart valve, often from a human donor or from cow or pig tissue, to replace a blocked or unhealthy valve.
If your LAD blockage is treated using angioplasty or stenting, you’ll usually need to spend at least one day in the hospital to recover. After that, you can go home and start doing normal activities again, such as going to work and exercising, after about a week.
If your doctor needs to perform heart surgery, you may need to spend three to seven days in the hospital before you’re cleared to go home.
You’ll likely wake up in the intensive care unit (ICU) with several tubes in your chest to drain fluids, an intravenous (IV) fluid tube in your arm to keep you nourished, and an electrocardiogram to keep an eye on your heart.
Once you get home, you’ll need to:
- Take care of your surgical incisions by keeping them warm, dry, and freshly bandaged a few times a day.
- Take any pain medications or blood thinners your doctor prescribes you.
- Avoid exercising or lifting anything over 10 pounds until your doctor says it’s OK to do so.
- Attend rehabilitation programs your doctor recommends to build up your heart’s strength and reduce your risk of having another heart attack.
Surviving the widowmaker is dependent on many factors, including:
- how quickly you’re treated
- what procedures are used
- whether your body goes into shock
- how your body recovers in the months and years following the heart attack
If you experience shock, your survival chances are around 40 percent. Without shock, your chances jump to about 60 percent or more.
And two crucial things to remember are that early diagnosis and prevention are paramount to not only preventing an LAD blockage but also increasing your chances of surviving one, especially in the long term.
Go to the ER right away if you notice any heart attack symptoms, and try some lifestyle changes either before or after having a heart attack to keep your heart healthy:
- Eat a heart-healthy diet of whole grains, healthy fats, low-fat dairy, and low sodium.
- Get plenty of exercise. Try light to moderate exercises for about 20 to 30 minutes a day.
- Stop smoking or using any kind of tobacco products.
- Keep your weight at an optimal level. Aim for a body mass index (BMI) of 25 or lower.
- Get plenty of regular, restful sleep, about six to eight hours a night. Try to go to bed and get up as close to the same time every day as possible.
- See your doctor or a cardiologist regularly to keep an eye on any early signs of heart disease or to make sure treatment’s working after a heart attack. Take any medications for your heart that your doctor recommends.
