Getting The Flu
A 2018 study found that people with the flu had a six times higher risk of a heart attack in the week after their infection. That startling finding highlights why it’s much better to prevent infections if possible because even seemingly minor infections can have serious complications. When viral infections, including the flu, travel to the heart, they can cause damage that leads to heart disease. It’s not known exactly how the flu impacts the heart, but we know the infection can increase inflammation, which is a risk factor for heart disease. So doctors recommend that everyone eligible, especially older adults, get their flu shot each year. The shot doesn’t just protect against a nasty seasonal infection; it also protects against an increased risk of cardiovascular conditions.
The flu increases the risk of heart disease by causing inflammation, putting strain on the heart, weakening the immune system, and exacerbating preexisting heart conditions. This can lead to the formation of blood clots, damage to blood vessels, and increase the risk of heart attack and stroke. People with heart disease or risk factors for heart disease should get a flu shot and take precautions to reduce their risk of getting the flu. If you do get the flu, get rest and stay hydrated. And if you’re high-risk, ask your doctor about antivirals.
