It has been indicated by epidemiological and abundant evidence that cardiovascular hospitalizations and all-cause mortality are contributed by influenza. Throughout the yearly winter epidemics, influenza is perceived as one of the significant factors behind mortality and morbidity, especially in the elderly population.

Australia has recorded the highest rates of hospitalization for influenza. Moreover, it also has been confirmed by the laboratory tests that in comparison to any infectious disease more mortality and morbidity in Australia is caused by influenza. A primary viral pneumonia is eventually caused by virus infection due to influenza. The virus is further contributed by secondary bacterial pneumonia. In addition, with underlying chronic diseases, influenza has resulted in higher mortality and severe diseases in Australians.

Besides mortality, it also has been found that different types of respiratory and cardiovascular hospitalizations are also contributed significantly by influenza. Throughout the yearly influenza season, deaths and AMI – acute myocardial infarction has also been recorded by past research studies. Moreover, it also has been predicted that in ischaemic heart disease, infection due to influenza has also been found. Due to which, in acute ischaemic cardiac events, influenza has been perceived as an underlying precipitant. Especially in adults who already were at risk of suffering from ischaemic heart disease. Potential health benefits of vaccination were found by the influenza vaccine.

It was also found that in the elimination of ischaemic events, a significant role can be played by the prevention of influenza through means of vaccination. As, in the prevention of severe influenza, the vaccination of influenza can be effective. In the elderly population, the incidence of death and pneumonia can be reduced by influenza vaccination. Moreover, the national expert committees have also prescribed it as one of the cost-efficient intervention. Whereas, in the case of younger adults, the potential health influence on ischaemic heart disease can also be reduced through influenza vaccination.

These research findings and studies eventually have lead global policies to consider the use of vaccination of influenza especially in order to prevent ischaemic cardiac disease morbidity in individuals who are less than sixty-five years of age. Moreover, over the past three decades, the evidence for influenza has increased exponentially as the trigger, including usage of influenza to prevent heart attacks and to prevent infection. In addition, the virus of influenza has also been found in heart muscle as pathological evidence and as the link between cardiovascular disease and winter infections and as the link between cardiovascular disease and respiratory infection. In cardiovascular diseases and in respiratory infections, a close connection between influenza and cardiovascular disease has been found especially in winters.
