Get a flu shot.

It's already standard advice from your doctor, but it may be even more important for senior

citizens at risk of heart attack.

Because a new analysis in the New England Journal of Medicine found that a flu infection

raises the risk of a heart attack by six times, and other viral

infections can also up the risk to a lesser degree.

These viruses cause the stress on the system overall, and so increases the metabolism,

and so people who are at risk for having a heart attack, that can tip them over.

Jeff Kwong is an epidemiologist at Public Health, Ontario and the Institute for Clinical

Evaluative Sciences. Quang and his team evaluated that risk by studying the histories of 20,000

older adults with confirmed cases of influenza. And they found that within one week of a flu

diagnosis, the group suffered six

times as many heart attacks on average than they did during control periods when they weren't sick.

Which Kwong says is another good reason to get a flu shot. You know, if you're a high risk for

heart disease, then it's probably a good idea to get one to reduce the chance of heart attacks.

And since they also found a link between heart attack risk and infection with other viruses, like respiratory syncytial virus,
