Flu Virus Can Raise Risk of a Heart Attack

Having the flu can raise your risk of a heart attack, new research from Canada finds. People who caught the flu, were six times more likely to have a heart attack in the seven days after contracting the virus, finds the study published in the New England Journal of Medicine.

Researchers looked at nearly 20,000 Ontario adult cases of the flu from 2009 to 2014 and found 332 patients who were hospitalized for a heart attack within one year of being diagnosed with the flu.

The lead author of the study says their findings reinforce the importance of vaccination.
