Although we briefly mentioned that influenza infection could exacerbate underlying cardiovascular disease in our Seminar, 1 we were unable to fully expand on this point because of word-count restrictions. In this regard, an epidemiological link between influenza and excess deaths associated with cardiovascular disease was suggested as early as in the 1930s. 2 Since then, several observational studies have supported an association between influenza infection, influenza-like illness, or respiratory tract infections and poor outcomes associated with underlying cardiovascular disease. In particular, a strong association with an increased risk of acute myocardial infarction has been reported. 2,3 Therefore, influenza vaccination could potentially prevent cardiovascular events; a Cochrane review evaluated evidence for this intervention. 4 The systematic analysis revealed that in randomised controlled trials that examined influenza vaccination as a mechanism of secondary prevention, significantly fewer cardiovascular deaths occurred in the vaccine group than in the control group (risk ratio 0·45, 95% CI 0·26–0·76; p=0·003). However, a difference was not observed for specific cardiovascular events such as acute myocardial infarction, and the effectiveness of influenza vaccination in primary prevention could not be assessed from available data. The findings from the Cochrane review had moderate bias because sample sizes were small and cardiovascular events were rare. However, the findings support influenza vaccination in individuals with cardiovascular disease, and are reflected in the recommendations for influenza vaccination from the US Centers for Disease Control and Prevention 5 and the European Centre for Disease Prevention and Control. 6 As stated by Caldeira and colleagues in their Correspondence, cardiovascular disease is a leading cause of death and disability worldwide. Mitigating the risk of influenza infection in this high-risk group through interventions such as vaccination could have a substantial positive effect on public health. More studies are needed to fully understand the association between influenza infection and cardiovascular events and the role of influenza vaccination as a prevention strategy. monkeybusinessimages We declare no competing interests.
