Low cholesterol doesn’t mean no coronary risk

SHARE Low cholesterol doesn’t mean no coronary risk

People with normal cholesterol levels probably think they needn't worry about a heart attack.

That may not be true. According to the Mayo Clinic Health Letter, about half the people who have heart attacks don't have high cholesterol by U.S. standards.

Researchers are increasingly interested in another potential indicator of heart disease, a protein known as high-sensitivity C-reactive protein. This protein may indicate inflammation in the arteries, a condition scientists believe plays a role leading up to a heart attack. But testing for the protein isn't routinely done.
