The Baby Boomer Heart: Cholesterol Rising
People between ages 45-60 years are at risk for high cholesterol. High cholesterol can build up even in trim, active people.
Balancing Your Risks: Food and Genetics
Unfortunately, it often doesn't take much for this delicate balance to go
awry, particularly as you age.
"Some folks are simply genetically prone to making too much LDL. They
aren't overweight, they exercise regularly, but as they get older HDL goes down
and LDL goes up, and they just make too much cholesterol," says Howard
Weintraub, MD, co-director of the New York University Lipid Clinic in New York
If you're one of them, you probably will need to eat a careful low-fat diet
and take medication eventually.
For the rest of us, experts say we are driving our cholesterol up with a
rich, high-fat diet and a lack of exercise. And in the process, we're putting
our hearts at risk.
What are the specific dangers? Krumholz says when LDL rises too high, it
collects and sticks inside artery walls. This contributes to clot formation,
and increases the risk of heart attack and stroke. It can also cause blood
vessels to become stiff and hard, which, in turn, increases the risk of high
Moreover, the latest research shows that LDL cholesterol also inflames
artery walls, causing a release of chemicals that may be directly related to
heart attack and even sudden death.
How to Tell if Your Cholesterol Is Putting You at Risk
Although cholesterol is a leading factor in heart disease, Underberg says
that, on its own, it's not a completely accurate predictor of heart disease
risk. It's just one factor of many risk factors that may eventually lead to
"It must be viewed in concert with what else is going on in your body --
your weight, body shape, blood pressure, and fitness level -- in order to
obtain a true picture of heart health," he tells WebMD.
New, more sophisticated tests are also attempting to tease out the actual
size of cholesterol particles in the body, which can make a difference in your
risk. In studies thus far, large pieces of LDL cholesterol appear to be less
dangerous for the heart than tiny particles, which sneak in under the lining of
an artery and lead to inflammation.
Nonetheless, your cholesterol counts. So it's important for adults to know
their total cholesterol count, as well as their LDL, HDL and triglyceride
levels. Call your doctor to get your numbers from your last physical when you
had blood work done. Then, compare them to these risk levels from the American
