More children are at increased risk for heart attacks, according to new research.

FOX News Radio's Bill Vitka reports:

It's not just bad cholesterol that can be a warning sign of heart trouble. And warning signs increasingly are turning-up in children. Evidence pointing to hardening of the arteries. It elevates the risk of heart attack. When it's seen in children, it's a sign of "accelerated aging", according to a new study reported by the Wall Street Journal.

The danger signs they find are bad cholesterol, high triglycerides and low HDL, which measure poor diet and sedentary lifestyle.

There is good news: Doctors believe that with exercise and a better diet heart health can be restored.
