Sometimes the flu sneaks up on us. We suddenly become feverish, weak and achy — with additional symptoms typical of a bad cold, such as a nasty sore throat. It’s an annoying experience for most younger, normally healthy people.
“But for older folks and people with certain medical conditions, such as heart disease, the onset of flu is potentially dangerous,” says Mary Anderson, manager of infection prevention at Edward Hospital.
Research shows people with a history of heart disease or stroke face a high risk of flu complications, such as pneumonia. Because pneumonia hampers the lung’s ability to get adequate oxygen into the blood, the heart has to work harder to make up for it.
The flu, and other viral infections, can affect blood pressure, heart rate and overall heart function. The flu is even associated with an increase in heart attacks and stroke. One 2018 study in the New England Journal of Medicine found that heart attacks are six times more likely in the seven days following a flu diagnosis.
Anderson says prevention is the best way to protect your heart from the flu:
According to the CDC, adults with heart disease or those who have had a stroke should seek prompt medical attention if they experience any of the following warning signs: difficulty breathing or shortness of breath, pain/pressure in the chest or abdomen, sudden dizziness, confusion, persistent vomiting, or flu-like symptoms that improve but return with a fever and worse cough.
If your flu symptoms are mild and you’re a TV fan, it’s the perfect time to settle in for a little guilt-free binge-watching. Whatever you do, take it easy, drink plenty of fluids and, in another week or so, the bout of flu should be behind you.
