Influenza vaccination could reduce the risk of both all-cause and cardiovascular mortality in heart failure (HF) patients, suggests a new study published in Circulation.
Researchers analysed data on 134,048 patients in Denmark newly diagnosed with HF over a 12-year period and assessed the association between influenza vaccination and survival.
The study found receiving one or more doses of the influenza vaccine was associated with an 18 per cent reduced risk of mortality (HR 0.82; 95% CI 0.81-0.84; P<.001 annual vaccination in september-october rather than november and december a greater cumulative number of vaccinations were associated with larger reductions the risk death when compared to intermittent vaccination.>
“Recent studies have indicated that the influenza vaccination coverage of patients with heart failure is inadequate,” said lead study author Daniel Modin, from the University of Copenhagen in Denmark. “I hope that our study can assist in making physicians and cardiologists who care for patients with heart failure aware of how important influenza vaccination is for their patients. Influenza vaccination may be regarded as a standard treatment in heart failure similar to medications.”
