Influenza increases heart attack risk six times in the first week of illness due to increased blood clotting and inflammation. Study conducted in the Netherlands.

The flu season has arrived, bringing with it the risk of not only respiratory illness but also an increased risk of heart attack. In fact, a recent study found that the flu virus can increase the risk of heart attack by six times. This correlation may come as a surprise to many, but the evidence is clear: the flu can pose serious risks to those with underlying heart conditions. Read on to discover why the flu virus can be so dangerous for your heart, and what you can do to protect yourself.


According to a recent article on the University of Minnesota’s website, people infected with influenza have been found to be six times more likely to suffer a heart attack within the first week of illness. This increased heart attack risk could be due to how a flu infection increases blood coagulation and inflammation, which in turn can increase clotting and weaken fatty plaques in the arteries.

The study, presented at the European Congress of Clinical Microbiology and Infectious Diseases and using test results from 16 labs across the Netherlands, along with death and hospital records, found that of 26,221 people with the flu between 2008 and 2019, 419 had a heart attack. Of those with heart attacks, 25 suffered them in the first seven days after flu diagnosis. The researchers estimate that people are 6.16 times more likely to have a heart attack in the week after flu diagnosis, similar to what Canadian researchers have found.

The link between influenza and heart attacks is a potentially dangerous one that must be taken seriously. Influenza already poses significant health risks to vulnerable populations, and this added risk of heart attacks can make it even more deadly. Healthcare providers must be aware of the heightened risk and take appropriate measures, such as prescribing antiviral therapy to mitigate the severity of the illness and reduce the associated risks.

It is also important for the general public to take steps to reduce the likelihood of contracting the flu in the first place. Practicing good hygiene, such as washing hands regularly and avoiding close contact with sick people, can help reduce the risk of infection. Getting vaccinated is another crucial step to take, particularly for those at higher risk of complications, such as the elderly and those with underlying health conditions.

For those who do contract the flu, it is important to be aware of the potential risks and to seek medical attention if symptoms worsen or if any unusual symptoms appear. With appropriate care and awareness, we can reduce the impact of this dangerous illness and minimize the risk of associated complications such as heart attacks.


In conclusion, the flu virus may seem like a minor illness, but it can have major consequences for your heart health. This year, it’s more important than ever to get your flu shot and take precautions to avoid catching the flu. If you do get sick, seek medical attention right away and follow your doctor’s instructions to minimize the risk of a heart attack. With some basic preventative measures, you can stay healthy and protect your heart from the dangerous effects of the flu. Stay safe and stay healthy!
