Flu may play part in plaque-rupturing heart attacks

Influenza vaccination can reduce the risk of a common type of heart attack in people over the age of 60, according to new studies suggesting that the virus plays a role in plaque rupture.

In a study published Thursday Journal of the American Heart AssociationUsing data from five consecutive seasons of influenza, Spanish researchers focused on 8,240 people who had a type 1 heart attack. They found that influenza and low temperature were each independently associated with an increased risk of that type of heart attack, and influenza vaccination could reduce that risk among people over the age of 60. I did.

“Our result is Influenza virus Play a major role in Plaque burstResearch author Dr. J Alberto Garcíaredo, Dean of the Department of Cardiology at the Principede de Asturias University Hospital in Madrid, said: “This study emphasizes the need to carry out preventive campaigns during the cold and flu season. The most important preventive tool we have is influenza vaccination.”

García-Lledó states that health professionals typically aim for 60% to 70% influenza vaccination rates not only for people over the age of 60, but also for people at high risk and health care workers. I did.

“Unfortunately, these goals have not been achieved in Europe or the United States. It is important to reach these goals and, if possible, exceed them,” he said. “Influenza is not a trivial illness. It causes many preventable deaths for reasons other than the respiratory illness itself.”

A 2018 study found that within a week of confirming a flu infection, the risk of a heart attack was six times higher.The survey results were the most prominent Senior citizens And those who are experiencing their first heart attack.A study published last year in more than 80,000 U.S. adults who were hospitalized for the flu over eight seasons of the flu turned out to be suddenly serious. heart Complications were common and occurred in 1 in 8 patients.

The American College of Cardiology and the American College of Cardiology have long been Influenza vaccine To protect against complications of cardiovascular disease. The Centers for Disease Control and Prevention recommends that all people over the age of 6 months be vaccinated against the flu vaccine each year.

In late March, the CDC said weekly influenza infections in the United States were “abnormally low.” However, authorities warned that COVID-19 is making it more difficult to measure cases of influenza, and that influenza activity could rise in the coming months.

The flu season usually peaks between December and February, but can last until May. That’s why the CDC is calling on people to be vaccinated against the flu again this spring.

Dr. Daniel Munoz said new research in Madrid was limited because it was conducted in a single metropolitan area with a warm climate.

Munoz, an associate professor of cardiology at the Vanderbilt University Medical Center in Nashville, who was not involved in the study, said, “We will see if these data can be replicated across diverse sequences of geographic locations. Would be interesting. “

But he said, “It was a wise and thoughtful study that shed more light on the idea that influenza is a systemic infectious disease. It has helped increase evidence that influenza vaccination can save lives.” I did.

The study also emphasizes the need for healthcare professionals to “think outside our clinical comfort zone,” Munoz said.

“As cardiologists, we learn traditional and proven risk factors such as smoking, diabetes, high blood pressure, and high cholesterol, but we also need to keep our eyes wide open on other risk factors. Patients You need to ask: “Have you been vaccinated against influenza?” And if necessary, educate them about the benefits of getting it. ”
