Can you assess your heart disease risk by looking in the mirror and =
checking for a receding hairline, earlobe creases, and yellow lumps of =
fat around your eye? Will sprinkling flaxseed on your cereal reverse =
hypertension? What about popping a probiotic to lower cholesterol?

These are just some of the quirkier findings coming out of the American =
Heart Association=92s annual meeting in Los Angeles this week along with =
high-tech advances in the diagnosis and treatment of heart disease.

Keep in mind that while scientific meetings of large medical societies =
allow for researchers and doctors to gather in one place to discuss =
hundreds, if not thousands, of new findings, what=92s often presented =
may not pass muster for publication in prestigious medical journals, =
where they first undergo rigorous peer review.

A Danish study drawing a lot of attention, but which has not yet =
published in a peer-reviewed journal, suggested that common signs of =
aging can predict a person=92s heart disease risk. The researchers =
analyzed data from nearly 11,000 participants over age 40 in the =
Copenhagen Heart Study and found that those who had three to four aging =
signs at the beginning of the study -- such as a receding hairline, =
baldness at the top of the head, creases in the earlobes, and fatty =
deposits around the eye -- had a 57 percent increased risk of having a =
heart attack and a 39 percent increased risk of being diagnosed with =
heart disease during the 35-year study compared with those who had none =
of them.
