Major winter storm brings warnings about heart attack risk of shoveling snow

TL;DR

  • Shoveling snow is linked to an increased risk of heart attack and sudden cardiac death.
  • Risk factors include diabetes, high blood pressure, high cholesterol, family history of heart disease, tobacco use, and a sedentary lifestyle.
  • Cold temperatures constrict blood vessels, increasing blood pressure and further straining the heart.
  • Shoveling snow can elevate heart rate to nearly maximal predicted levels.
  • Recent deaths during a winter storm were attributed to cardiac events during snow removal.
  • A Canadian study found increased cardiac hospitalizations and deaths from heart attacks in men following heavy snowfall.
  • Individuals with cardiac risk factors are advised to avoid shoveling or take frequent breaks.
