Heart Beat: Teachable moment
What should family members do after a brother, sister, or parent has what doctors call a "premature" heart attack (one before age 55 in a man or 60 in a woman)? Provide support, for sure. After that, though, each family member should talk with a doctor to gauge his or her own cardiac risks. That's what Scottish researchers propose in the Sept. 8, 2007 issue of the medical journal BMJ.
Heart disease tends to run in families. In a national study of more than 130,000 families, those having one or more members with heart disease represented only 14% of the general population but accounted for a staggering 70% of premature heart attacks and 86% of early strokes. How much of this is due to shared genes and how much to shared lifestyles or habits isn't yet known.
