Influenza infection is associated with an 18% increased risk for atrial fibrillation, which may be reduced through influenza vaccination, according to new research published in Heart Rhythm.
Researchers conducted an observational study to determine whether influenza infection is a risk factor for AF and whether vaccination could reduce that risk. From 2000 to 2010, they identified 11,374 patients with newly diagnosed AF from the Taiwan National Health Insurance Research Database who were then matched by age and sex to four control (without AF) patients each. The reference group consisted of patients without influenza infection and vaccination.
