The flu virus can trigger a heart attack.


The flu virus can trigger a heart attack.

Flu doesn’t just make you feel bad. It may also increase the risk of heart attacks, a study published on Wednesday found.

The study authors, epidemiologists and family doctor Jeff Dr Kwong said: “we found that, compared with a year after the infection or infection before and after being diagnosed with flu happen within a week to six times higher risk of heart attack. Institute of clinical assessment science and public health, Ontario, Canada.

The results appear in this week’s New England journal of medicine.

Doctors have long noticed a link between seasonal flu and cardiovascular death, but the link is difficult to determine. Part of the challenge is that many people with flu-like symptoms have not been tested for the virus. So kwong and his colleagues decided to use test results (from flu tests and other viruses) and match them with hospital records.

“This is the first time we have a laboratory confirmed flu, so we are sure these are the infections caused by influenza [virus],” kwong said.

There are many things that happen during the flu that can help explain the increased risk of heart attack.

“Inflammation is going on and your body is under a lot of pressure,” Kwong explains. Oxygen levels and blood pressure may decline. These changes “may lead to increased risk of thrombosis in the heart vessels”.

Healthy young people are less likely to have a heart attack during the flu season. “It’s about your baseline risk,” says Kwong.

In his study, people who had a heart attack during the flu were elderly. “Most of them are over 65, and many of them are at risk for heart disease, such as high blood pressure, high cholesterol or diabetes,” said Kwong.

Influenza vaccines do not always protect against influenza viruses. Over the years, this camera has provided more protection than others. Only about 30% of the study population was vaccinated during that season. But flu stalkers say some protection against the virus is better than none.

“If we can reduce the risk of contracting the flu, we should reduce the risk of a heart attack,” kwong said. So “getting the flu shot is a good idea.”

Infectious disease experts at the centers for disease control and prevention say it’s not too late to get a flu shot this season. There is a lot of flu in the United States right now, and the rate of hospitalization is still going up. So the storm is not over.

“There may be another wave,” said Dr. Alicia Fry, of the CDC’s influenza division. She says the department has seen flu outbreaks in some nursing homes.

For those who get sick from flu symptoms, flay has the advice: “it’s really important to stay at home.” She says don’t go to work – or send your kids to school if they’re sick.

New research suggests that the risk of infecting colleagues or classmates can be far greater than making them feel bad.
