A new blood test could give patients a better idea if they're at high risk for having a heart attack.
Researchers found elderly people with high levels of a blood marker called CRP had a 45% increase in their risk of developing heart disease within 10 years. CRP is a marker for inflammation in the blood.
The report in Circulation, which is a journal of The American Heart Association, offers more evidence that inflammation plays an big role in heart disease. Again, it's a simple blood test called CRP, if you want to ask your doctor about it.
