Can the flu increase my heart attack risk?
Q. There has been a lot of talk about the severity of this flu season, and I recently heard that influenza also can trigger a heart attack. Should I worry?
A. Influenza is responsible for about 10,000 to 20,000 annual deaths, mostly from pneumonia or internal organ failure. In other situations, influenza infection strains a person's health, which can worsen underlying conditions, such as heart disease.
