The link between flu and myocardial infarction reinforces the value of the influenza vaccine and raises the possibility of prophylactic anticoagulation to reduce risk.
The link between influenza infection and a rise in short-term risk for acute myocardial infarction has been reaffirmed in a new study, which showed the risk appears to be particularly elevated in individuals with no prior diagnosis of coronary artery disease .
The adjusted relative incidence of acute MI during the risk period compared with during the control period was 6.16 . "The fact that we found similar results to Kwong et al strengthens the finding that acute flu infection is linked to increased MI risk. This is becoming more and more clear now. It also shows that this effect is generalizable to other countries," Bruijning-Verhagen said.The researchers moved the field ahead by also looking at whether there is a difference in risk between individuals with flu who already had cardiovascular disease and those who did not.
Influenza can cause a hypercoagulable state, systemic inflammation, and vascular changes that can trigger MI, even in patients not thought to be at risk before, she pointed out. And this is on top of high cardiac demands because of the acute infection.
