Q. Glen, Are Heart Attack Risk Genetic?
A. At the risk of being Captain Obvious, your chance of having a heart attack is largely tied in with your diet and fitness choices. But there may be one other factor to consider: your genes.
Two new studies, from separate research teams, show that gene variants in a certain chromosome may make coronary heart disease -- which is the number one cause of death in the U.S. -- and heart attacks more likely.
The scientists don't know exactly what the gene variants in chromosome 9p21 do, but their findings suggest that the effects aren't good for the heart.They screened the DNA of more than 23,000 white people in Canada, the U.S., and Denmark. A common variation in chromosome 9p21 was "consistently associated" with coronary heart disease.
The genetics of heart disease may differ among ethnic groups, note the researchers. The researchers aren't recommending gene tests, and they're not blaming the gene variants for all coronary heart disease or heart attacks.
The studies did not include information on the participants' diet, exercise, medical care or other heart-related lifestyle habits.
