Heart attack: the flu vaccine could reduce the risk by half


Myocardial infarctionmore commonly known as heart attackis destruction of part of the muscle of the heart (more or less extensive) which is not insufficiently supplied with oxygen.

Inserm accounts for approximately 80,000 cases each year in France and the number of deaths is estimated at 12,000 per year. Quick support allows to limit the sequelae.

Heart attack survivors run a high risk of having another heart attackabove all the 12 months following the attack. But it seems thata simple flu vaccine can reduce this risk. A study from the University of Orebro in Sweden and another from a research team in Peru assure that receiving an injection within three days after the infarction protects patients from recurrences.

Infarction: the flu vaccine reduces the risk of recurrence by 40%

Early work, conducted by Swedish researchers, observed 3,000 patients who were victims of a heart attack, resulting from eight countries, including the UK. Scientists have divided the participants into two groups. The first had a vaccine against influenza in three days after admission to hospital. On his side, the second received a placebo.

Over the next twelve months, the team observed a 40% reduction in cardiac death in people who had a flu shot within 72 hours following their hospitalization.

The second survey, carried out in Peru, focused on data from over 4,000 patients. Experts have found that vaccination against influenza reduced the risk of dying by 47% of a second heart attack.

A solution to reduce heart attacks?

However, be careful, if the deaths decrease, recurrences no. Indeed, both studies revealed similar rates of second heart attack in all participants (vaccinated and unvaccinated). This suggests that the flu virus does not prevent the occurrence of another heart attack, but it seems to reduce its severity and lessen the sequelae.

Asked by the Daily Mail, Professor Naveed Sattar, from the Institute of Cardiovascular and Medical Sciences at the University of Glasgow, told Daily Mail – who was not involved in this work – confirms the interest of this discovery: “The flu stresses your arteries and makes your blood thicker, so if you have heart disease, it could push you over the threshold for a heart attack. And the risk of it happening again is highest in the first six to 12 months. These results suggest that it’s a good idea not to wait until winter and get a flu shot right away.”
