Heart Scans and Heart Attacks

You may have heard about them - heart scans that tell you you might be at risk of having a heart attack. But are they for everyone?

Thinking about getting one of those high-tech heart scans? According to a new study in the journal of the American Medical Association, the use of cardiac imaging, can expose patients to high doses of radiation and methods that can reduce the radiation dose are not always used.

The images are designed to spot plaque buildup and other irregularities in the vessels of the heart. Early warning can prevent heart attacks. But the researchers behind the Jama study say patients should weigh the increased risk of cancer with the benefits of routine heart scans.

The American Heart Association recently recommended people without symptoms of heart disease should talk to their doctors and think twice before having these procedures.

And is it too late to get a flu shot? Flu season is at it's peak, but we still have a long way to go. Influenza season usually runs from November until April. States like Virginia and New Jersey are reporting widespread flu outbreaks. The centers for disease control says if you haven't gotten a flu shot, get one soon. Shots usually take about two weeks to take effect.
