There are test to determine DNA for genes linked to heart disease, but at hundreds of dollars per test, are they really worth it?

New research on women suggests the answer is "no".

While the genes are linked to increased heart risk, they don't tell doctors and patients anything new.

Scientists reporting in the Journal of the American Medical Association say people with these genes generally have more obvious risk factors such as obesity, relatives with heart disease and high cholesterol.

Besides, many doctors say patients shouldn't need an expensive test to tell them to eat better and get more exercise.
