Influenza: Study Shows That Acute Cardiovascular Events Prevalent Among Hospitalized Adult Influenza Patients. Flu Vaccination Highly Recommended
: A new large population-based study led by the US CDC and in collaboration with numerous institutions has shown that acute cardiovascular events, especially heart failure and ischemic heart disease, were found to be common among patients hospitalized with influenza.
The researchers suggest that vaccination is particularly important among those with cardiovascular risk factors.
The research findings were published in the journal: Annals of Internal Medicine. https://www.acpjournals.org/doi/10.7326/M20-1509
Typically annual influenza epidemics in the United States result in 140,000 to 810,000 hospitalizations and approximately 12,000 to 61,000 deaths each year. Although respiratory disease is a hallmark of influenza virus infection, cardiovascular events are also important complications of influenza.
The stud team from the National Center for Immunization and Respiratory Diseases, Influenza Division, Centers for Disease Control and Prevention (CDC) used data from the U.S. Influenza Hospitalization Surveillance Network (FluSurv-NET) during the 2010-to-2011 through 2017-to-2018 influenza seasons to examine acute cardiovascular events in adults with a hospitalization associated with lab-confirmed influenza.
Altogether more than 80,000 patients were included in the analysis. The researchers found that almost 12 percent of patients hospitalized with influenza had an acute cardiovascular event.
It was found that the most common such events were acute heart failure and acute i
schemic heart disease. Older age, tobacco use, underlying cardiovascular disease, diabetes, and renal disease were significantly associated with higher risk for these events. As such, the study team suggests that clinicians should ensure high rates of vaccination, especially in at-risk populations.
With the ongoing COVID-19 pandemic going on and the flu season fast approaching, it is expected that the coming season could see a catastrophic Flu/COVID-19 season. Individuals in high risk groups and those vulnerable should consult their doctors about getting their flu vaccinations.
