Flu vaccination reduces the risk of cardiovascular events by 50%

A new Canadian study shows that annual flu shots will help patients with a history of cardiovascular disease more than halve their risk of cardiovascular events such as stroke or heart attack.

The results of the study published on October 22 show that patients with acute coronary syndromes have a 36% reduced risk of heart attack, stroke or heart failure within a year after seasonal flu vaccination. . This rate increased to 55% in people who just got sick.

The study was conducted based on the results of a clinical cardiovascular health test in more than 6,700 patients with acute coronary syndrome in the average age of 67. Of these, some were vaccinated against influenza, with people were given a placebo and some were not vaccinated

Results showed that among those who were not vaccinated against influenza or only placebo, there were 151 patients with severe cardiovascular events within a year. Meanwhile, the number of people with severe accidents after being vaccinated is only 95 people.

In patients with early onset of cardiovascular disease, the risk of complications was also significantly reduced in those who received the vaccination against the flu compared to those who were not vaccinated or only received placebo, with the corresponding rate of 23.1% and 10 , 3%.

Speaking to reporters, the research leader, a cardiologist at the Women's College Hospital in Toronto, Jacob Udell stressed that vaccination against influenza is a cheap, safe and easy-to-manage therapy. However, researchers need to continue to expand clinical trials in order to make an official conclusion about the effect of flu vaccination on cardiovascular patients.

Cardiovascular diseases are one of the leading causes of death for North Americans. Therefore, this new study by Canadian scientists will help significantly reduce the burden on the health care system.
