The study, which was released by New England Journal of Medicine, was based on about 20,000 adult cases of laboratory-confirmed influenza infection in Ontario, Canada between 2009 and 2014.

“Our findings are important because an association between influenza and acute myocardial infarction reinforces the importance of vaccination,” revealed Jeff Kwong, the lead author of the study and a scientist at the Institute for Clinical Evaluative Sciences and Public Health Ontario.
It has been observed that the risk for a heart attack was higher within the first week of acquiring influenza. While other respiratory viruses were also seen as factors for the increased risk of a heart attack, they were not as potent as the flu virus.
“It’s not every day you see a six-fold increase in the risk during the first seven days of lab-confirmed influenza. We were also surprised the risk dropped off to nothing by day 8 and beyond,” Kwong said.
Because of the findings, Kwong has urged new “international guidelines that advocate for influenza immunization in those at high risk of a…
