How shoveling snow can lead to a heart attack

 Glistening, white snow may be stuff of greeting cards, but to cardiologists, it's a heart attack waiting to happen.

Shoveling the white stuff can not only hurt your back, but it can also be hard on your heart.

Heart attacks during shoveling usually occur when people rush to clear a heavy amount of snow.

On January 29, an elderly man collapsed while shoveling snow in his driveway in Etobicoke, Ontario. When paramedics arrived he was showing no vital signs and later died.

So just how dangerous can this act of outdoor winter labor be?

Health officials say blood vessels are tighter in the cold weather, making it harder for blood to pass through them. Combine that with the stress of physical activity, and it can mean disaster for some unsuspecting shovellers.

WHO'S AT RISK?

According to MetroHealth, patients who have a known heart disease condition, have high blood pressure, high cholesterol and/or are smokers are at highest risk of a heart attack while shoveling snow.

The Heart and Stroke Foundation recommends that anyone who has ever had a heart attack, stroke, or heart surgery should have someone else do the shoveling or should speak to their doctor before taking on such a task.

SIGNS TO LOOK OUT FOR:

While shoveling the snow, watch for the following warning signs:

Lightheadedness

Dizziness

Being short of breath

Tightness or burning in chest, neck, arms or back

If you experience any of these warnings signs while shoveling, sit down and rest. If the feeling continues for more than a few minutes call 911.

THE DOS AND DON'TS:

Be sure to talk to your doctor before tackling the snow.

Avoid shoveling immediately after you waking up in the morning as most heart attacks occur early in the morning when blood is more prone to clotting. Wait for at least 30 minutes and warm up.

Do not eat heavy meal before shoveling: blood gets diverted form the heart to the stomach.

Warm up your muscles before starting by walking for a few minutes or marching in place.

Do not drink coffee or smoke for at least one hour before or one hour after shoveling or during breaks.

These are stimulants and elevate your blood pressure and heart rate

PLAN ACCORDINGLY:

Use a small shovel: shovel many small loads instead of heavy ones.

Begin slowly and take frequent, 15 minute breaks.

Drink plenty of water to avoid dehydration Dress in layers, to avoid hypothermia (low body temperature) or overheating.

Cover your head and neck (50% body heat lost through head and neck).

Cover your mouth (breathing cold air can cause angina or trigger breathing problems.
