Nearly 12% of adults hospitalized with flu had an acute cardiovascular event, according to results of a population-based study published in the Annals of Internal Medicine.
In this ross-sectional study, data from 89,999 adults with laboratory-confirmed influenza included in the U.S. Influenza Hospitalization Surveillance Network were analyzed.
A total of 80,261 patients had complete medical records and ICD codes available. Acute cardiovascular events were found in 11.7% of patients with the most common including acute heart failure (6.2%) and acute ischemic heart disease (5.7%). A higher risk of acute heart failure and acute ischemic heart disease was significantly associated with older age, tobacco use, underlying cardiovascular disease, diabetes, and renal disease.
The authors concluded that clinicals should encourage patients with underlying chronic conditions to get the flu vaccine to protect against acute cardiovascular events.
