Snow STEMI

Posted on February 23, 2026 by Patrick Hercules

A powerful winter storm called a Nor’easter has brought blizzard-like conditions and a large amount of snowfall to our area.

When we get such large amounts of snow, the easy part is watching the beauty of the snow falling. Unfortunately, the most difficult part is having to shovel several inches of snow from the sidewalk and driveway.

A major worry when shoveling large amounts of snow is how it can affect our health.

According to the National Library of Medicine, heavy snowfall, cold temperatures, and low atmospheric pressure during the winter months have been associated with increased adverse cardiovascular events, such as “snow-shoveler’s ST-elevated myocardial infarction (STEMI).”

Snow-shoveler’s STEMI is a type of heart attack that occurs when there is a partial or complete blockage in one of the coronary arteries, which stops blood flow to part of the heart muscle. This can especially occur due to the over-exertion caused by shoveling snow.

Per the American Heart Association, shoveling snow can put some people at risk of a heart attack, but most people won’t have a problem. Sudden exertion, such as shoveling hundreds of pounds of snow or pushing a heavy snow blower after being sedentary for several months, can put a huge strain on the heart.

There is also a factor of cold weather, as it can increase heart rate and blood pressure, and make blood clots form more easily and constrict arteries, which can decrease blood supply. This can even affect healthy people. People who are over the age of 40 years old, or are relatively inactive, are especially at risk. Other people who are at risk of STEMI include:

Those with preexisting heart conditions:

Those with high blood pressure (hypertension)
Those who smoke tobacco products

According to Medical News Today, research indicates that heavy snowfall is linked to a 6% higher likelihood of hospital admission for men with a heart attack and a 34% increase in dying.

The National Safety Council recommends the following safety tips to shovel safely:

Know the signs of a heart attack, stop immediately, and call 911 if you’re experiencing any of them; every minute counts

The warning signs of a heart attack include:

- Chest discomfort that lasts more than a few minutes or doesn’t go away and returns
- Pain or discomfort in the arms, back, neck, jaw, and stomach
- Shortness of breath

Other signs of a heart attack can include:

- Breaking out in a cold sweat
- Nausea
- A rapid or irregular heartbeat
- Unusual tiredness
- Heartburn or indigestion
- Lightheadedness

Take it slow and stretch before you start shoveling
Shovel only fresh, powdery snow because it is lighter
Push the snow instead of lifting it. If you do lift the snow, use a small shovel or only partially fill the shovel
Lift with your legs and not your back
Dress in warm layers
Do not shovel after eating or while smoking
Do not work to the point of exhaustion

If you have a history of heart disease, do not pick up a shovel without the permission of your healthcare provider.

If you or a loved one is experiencing symptoms of STEMI, while, during, or after shoveling snow, you can receive treatment from a cardiologist at Flushing Hospital Medical Center’s Ambulatory Care Center. To schedule an appointment, please call (718) 670-5486. If you are experiencing an emergency, please call 911 immediately.

How To Stay Heart Healthy in the Winter

Posted on February 7, 2020 by Michael Hinck

When asked which season has the highest incidence of cardiovascular problems, most wouldn’t guess the winter, but it is true, especially in cities like New York City, which are known for harsh weather conditions.

One of the main reasons for this is our blood vessels constrict in the cold weather. This happens because our bodies work hard to protect vital organs such as our brain and lungs from extreme conditions by preserving blood flow. As a result, our heart has to beat harder and faster to supply the rest of the body with the oxygen it needs. As your heart rate and blood pressure increase, you raise your risk of blood clots, stroke, and heart attack.

Another factor for increasing our risk of developing cardiovascular disease in the winter is our diet. Both the quality and quantity of food we consume can have a significant role in our heart health during any time of the year, but it is especially important during cold weather months because to digest a heavy meal requires increased blood flow to the stomach, which, for previously stated reasons, can be difficult due to blood vessel constriction.

In addition to cold weather, the winter also brings with it an increased risk of contracting the influenza (flu) virus. Flu season typically is most prevalent during the winter months and fighting it (as well as other viruses) can place an increased amount of stress on the heart and can drain the body of its energy. For those with an already weakened heart, such as the elderly or those with a weakened immune system, this can be very dangerous.

Loneliness and depression have also been linked to an increased risk of heart attack by as much as 30%. The development and maintaining of social relationships is never more difficult than during the winter months due to a variety of factors. One major factor is the weather. The frigid conditions limit the ability to attend social events. In addition, the days are shorter and darker in the winter, which can also increase the likelihood of depression.

Lastly, the winter weather can also limit an individual’s ability to properly maintain their health. This can include interfering with a person’s ability to exercise regularly as well as allowing them access to critical healthcare resources, such as seeing their provider when they aren’t feeling well or refilling their medications. Failure to do so can have harmful effects on someone’s heart health.

Recognizing the increased heart health risk factors in the winter and taking steps to address them are vital to staying healthy in the winter. This includes making sure to avoid very cold temperatures and dressing warm, eating a heart healthy diet, getting your flu shot, maintaining social relationships, and closely monitoring your health, including seeing your doctor regularly and adhering to your medications.

Safety Tips For Shoveling Snow This Winter

Posted on February 9, 2018 by Michael Hinck

Winter and snow go hand in hand and this weekend’s forecast calls for snow. In preparation of this, Flushing Hospital would like to provide you with some heart health tips before you go out to shovel snow.

By now, we have all heard about the risk of shoveling snow and suffering a heart attack, but is this true? The fact is shoveling snow (or to a less extent, even pushing a heavy snow blower) is considered a more strenuous activity than running full speed on a treadmill. But why should pushing around some white flakes be more dangerous than any other form of exercise?

The biggest reason why heart attacks are so common while snow shoveling has as much to do with the weather as it does with the activity. The cold temperature is a key contributor to the onset of a heart attack. Frozen temperatures can boost blood pressure, interrupt blood flow to the heart, and make blood more likely to clot.

Another factor to consider is who is doing the shoveling. If you are a healthy and physically fit individual there is much less of a risk to suffer a heart attack, but unfortunately not everyone who attempts to shovel snow fits into that category. For those who do not exercise as frequently, (especially during the winter when we tend to be less active) or have a history of hypertension or heart disease need to follow the following tips before going out to shovel:

Avoid shoveling as soon as you wake up as this is when most heart attacks occur
Do not drink coffee, eat a heavy meal or smoke cigarettes immediately before or while shoveling
Warm up your muscles before you begin
Shovel many light loads instead of fewer heavy ones
Take frequent breaks
Drink plenty of water to avoid dehydration

Know the early signs and symptoms of a heart attack. If you experience a squeezing pain in your chest, shortness of breath, racing heartbeat, pain radiating from your left shoulder and down your left arm, cold sweats, accompanied by fatigue and nausea, stop shoveling, go inside and call 911 immediately.
If you are at a high risk of suffering a heart attack, avoid shoveling snow completely. Try asking a family member, friend or neighborhood teen to help you out.
