Although beautiful to look at from the comfort of your living room, winter storms have a dark side that contrasts with the splendor of that frosty whiteness. If shoveling snow is on your to-do-list, be sure to listen to your heart, says UR Medicine heart specialist Dr. John Bisognano.


If it has been a while since you have done any strenuous physical activity, you might want to think twice before venturing out to shovel. Tackling heavy snow can result in more than muscle stiffness or back pain.


The big question is, can it cause a heart attack? One study that showed 7 percent of men started experiencing heart attack symptoms while shoveling snow.


If you are not used to physical exertion, there is a risk to shoveling snow. The combination of cold temperatures, aerobic activity, and heavy lifting of snow create a physical demand on your body. This activity that can unmask any existing or underlying heart disease that you may not have even been aware of.


Men who smoke or have a family history of heart disease often report that they first recognized their symptoms while shoveling snow. Activities, such as shoveling, that place demanding, unexpected, and often prolonged exertion on the body along with frigid temperatures places a heavy burden on the heart, causing it to require more oxygen. If there is any dysfunction of the heart muscle or narrowing of the coronary arteries that supply blood to the heart muscle, oxygen demand can be greater than the supply, leading to chest pain and even heart attacks.


The best advice is to maintain a constant level of physical activity year-round. Think of it as being in training for the strenuous activity of snow shoveling.


Work with your physician to monitor blood pressure and cholesterol. While these can be influenced by close attention to lifestyle, many people need medications to keep blood pressure and cholesterol under control. These medications are inexpensive and well tolerated.


Listen to your heart


So, start easy and listen to what your heart is telling you. During the warmer months, stay active, and keep close tabs on your blood pressure, cholesterol, weight, exercise, and lifestyle.


Take note of the following symptoms:


Shortness of breath


Chest, shoulder, neck, or arm pain


Dizziness, fainting, sweating, or nausea


If you experience these symptoms, pay close attention. It could be your heart trying to tell you something important or maybe you could be one of the lucky ones to get off with just a warning.
