Special thanks to William B. Borden, MD, associate professor of medicine and health policy at George Washington University, and William Schaffner, MD, medical director of the National Foundation for Infectious Diseases (NFID), for this guest blog post during American Heart Month, held annually each February.
Heart disease is the leading cause of death for men and women in the US—each year, one in four deaths are caused by heart disease. As a federally designated event, American Heart Month is an ideal time to raise awareness about the importance of heart-healthy lifestyle choices, including annual influenza (flu) vaccination.
Flu can be particularly serious for those how have heart disease or have had a stroke. In fact, 28+ million US adults have heart disease and are at six times increased risk of heart attack within seven days of flu infection. An increasing body of evidence points to inflammation as the mechanism by which flu exacerbates heart disease. Exacerbation of existing heart disease may result in blocked arteries, which can lead to a heart attack or stroke.
Yet, one of the most effective measures to prevent a cardiovascular event is often overlooked—an annual flu vaccine.
Unfortunately, in the US, flu vaccination rates remain well below public health goals each year. During the 2018-2019 flu season, only 45 percent of adults got vaccinated against flu, and a recent NFID survey found that one in four high-risk patients do not intend to get vaccinated this season. Clearly, there is more that can be done to protect patients—and their hearts—against flu.
As trusted resources for their patients, healthcare professionals, including specialists, must insist upon annual flu vaccination as part of disease management discussions.
To address this important public health issue, NFID and the American College of Cardiology joined with leading medical and patient advocacy groups to review the science around the dangers of flu in adults with heart disease and other chronic health conditions. The discussions resulted in an NFID Call to Action, which urges all healthcare professionals to prioritize annual flu vaccination for patients with chronic health conditions, and outlines various strategies to improve flu vaccination rates, including:
- Inform adults with heart disease (and other chronic health conditions) that flu can exacerbate their condition or trigger an adverse cardiovascular event
- Insist on flu vaccination for all patients through the duration of flu season (September–March)
- If your practice does not offer vaccines, write a prescription for a flu vaccine and insist that patients get vaccinated at a local pharmacy or other convenient location
- Highlight the benefits of flu vaccine in reducing the risk of severe illness and related outcomes, even if a patient does get the flu
- Emphasize the increased risk of post-flu frailty—individuals with heart disease may experience permanent physical decline, impacting their ability to remain active and independent.
When it comes to annual flu vaccination, there is no time like the present. American Heart Month is the perfect time to remind patients why flu vaccination is critical to protecting their health. After all, there are many important things you already advise patients to do to stay healthy: eat a balanced diet, quit smoking, exercise, take medications as prescribed. Make sure to include a strong recommendation for annual flu vaccination as well!

In the US, heart disease is a leading cause of death, causing one in four deaths. To help raise awareness about the importance of a heart-healthy lifestyle, American Heart Month is observed in the US each February, making it the perfect time for healthcare professionals to talk with at-risk patients about the need to stay up to date on all recommended vaccines …
Despite common misconceptions, influenza (flu) is not just a common cold. Anyone can get sick with flu, but certain individuals are at higher risk of developing serious flu-related complications, including those with chronic health conditions such as heart disease, lung disease, and diabetes …
In honor of American Heart Month, NFID and the American Heart Association (AHA)—a proud supporter of the NFID Keep Up The Rates campaign—encourage individuals with chronic conditions to receive all of their recommended vaccines, despite delays that may have been caused by the COVID-19 pandemic …
