The danger of a
heart attack six times higher than the year before or after the first seven days following an influenza infection. The risk was particularly high in elderly patients, those infected with strain B of the virus and for patients who had their first infarction. In recent years, several studies have been conducted on the subject. Why we influenza at an increased risk of heart attacks and stroke leads, but is not yet fully understood, he said in the release.
Basically, all infections lead to systemic infections and inflammation leading to an increased risk of Cardiovascular illnesses, To the
influenza but other factors may be added to aggravate. One hypothesis is that virus leads to a clot of existing atherosclerotic plaques (deposits) and thus causes acute coronary occlusion, that is to say a blockage of the coronary arteries. Other potential causes include reduced anti-inflammatory activity or increased circulation of macrophages (macrophages – "phagocytes" of the immune system) in the arteries.
As early as 2015, another analysis of several studies not only showed that heart attacks more common in patients with influenza but also that one vaccination reduce the risk. The calculated efficiency of vaccination so was just under 30 percent. Also the cardiovascular condition mortality should be reduced by vaccination. According to Cochrane Library analyzes, 2.3% of deceased patients had a bias in the vaccinated group, but more than double (5.1%) in the unvaccinated group.
