Study Says Heart Disease Begins in Youth

July 24 -- Drop the chalupa. While youre at it, drop that Big Mac and Double Whopper as well.

A new study examining the bodies of 760 teenagers and young people found early signs of blocked coronary arteries caused by cholesterol buildup, suggesting that preventing future heart disease is a pediatric problem, researchers announced today in the journal Circulation.

The bottom line is that long-range prevention of coronary artery disease has got to begin in childhood, or at least adolescence, says senior researcher Dr. Henry McGill, senior scientist emeritus at Southwest Foundation for Biomedical Research in San Antonio.

Artery Disease Begins in Childhood

The study examined the arteries of young people who died of other causes, such as suicide, homicides and accidents.

One-fifth of the young men aged 30-34 already had advanced plaques, or deposits of fat, inside their coronary artery, pointing the way toward future heart attacks and strokes. Males were more than twice as likely to have the plaques than women of the same age range.

The biggest risk factors for a clogged artery were found to be obesity and a high level of low-density lipoprotein or LDL, the so-called bad cholesterol that forms deposits on artery walls. Those with LDL levels above 160 milligrams per deciliter were 2 ½ times more likely to have one of these advanced plaques.

Other risk factors, such as smoking, high blood pressure, and having a low level of high-density lipoprotein or HDL, known as the good cholesterol, also put people at a slightly higher risk of artery blockage.

Early Cholesterol Tests Suggested

This research follows on the heels of a study that came out only last week that found that young men in their 20s and 30s with high cholesterol are 2 to 3 ½ times more likely to die of heart disease, and have four to nine less years of life expectancy than men with healthier cholesterol levels.

Both pieces of research suggest that even people in their early 20s should be getting their cholesterol tested, as is currently recommended by the National Cholesterol Education Project, says Dr. Peter Libby, chief of cardiovascular medicine at Brigham and Womens Hospital in Boston.
