6 Heart Disease Genes Found
Variations in Those 6 Genes May Make Heart Disease More Likely Before Age 66

July 18, 2007 -- The odds of getting heart disease may lie, in part, in six
genes identified today by European researchers.
Variations in those six genes appear to be more common in people who have
heart attacks or heart disease before age 66, according to the scientists.
But that doesn't mean that people with those gene variations are doomed to
develop heart disease or suffer a heart attack at a young age.
"Even if a person carries one or more of these risk variants, they can
still do a lot to reduce their risk by adopting a healthy lifestyle, not
smoking, and, if they have high blood pressure or raised cholesterol levels, to
have these treated," Nilesh Samani, FMedSci, says in a news release.
Samani works at England's University of Leicester and was involved in the
heart disease gene study, which appears in today's online edition of The New
England Journal of Medicine.
Heart Disease Genetics
Heart disease is the leading cause of death for U.S. men and women.
Heart disease risk may be handed down from generation to generation through
genes. But genetics are only part of the story.
For instance, it's well known that smoking makes heart disease (and many
other health problems) more likely. So do obesity and inactive lifestyles.
Samani's study focuses only on genetics -- not whether people were couch
potatoes, how often they exercised, whether they ate leafy green vegetables
every day or once a decade, or had any other habits that might sway their heart
The key question: Were the genetic cards stacked against certain people?
