WATERLOO (KWWL) -- With another round of snow on the way, the American Heart Association is sending a reminder that shoveling snow is an athletic event.
The heart health advocates say even this past week, a Coralville man died of an apparent heart attack while shoveling snow at home.
For people who don't get regular physical activity, shoveling snow can trigger a cardiovascular emergency. People who suffer cardiac arrest need CPR immediately or they're unlikely to survive more than 10-12 minutes.
The American Heart Association gives these warning signs for a heart attack, saying that often times it's not the obvious event that you see in the movies.
