Association of influenza-like illness activity with hospitalizations for heart failure: The Atherosclerosis Risk in Communities study
JAMA Cardiology — Kytömaa S, et al. | May 06, 2019DVERTISEMENT
In this community surveillance study involving ~451,588 adults (aged 35-84 years), researchers focused on the temporal link between influenza activity and hospitalizations attributable to heart failure (HF) and myocardial infarction (MI). They obtained data from adults residing in the Atherosclerosis Risk in Communities study communities from annual cross-sectional stratified random samples of hospitalizations during October 2010 to September 2014. A 24% increase in HF hospitalizations rates were observed within the same month in relation to a 5% absolute increase in influenza activity. However, no significant increase in MI hospitalizations was observed in relation to a 5% absolute increase in influenza activity. Findings revealed a temporal link between influenza activity and an increase in HF hospitalizations across four influenza seasons.
