The whole document is available from the American Heart Association
at http://circ.ahajournals.org/cgi/reprint/109/22/2807, so I would
recommend that people concerned about this risk talk over these
guidelines with their primary care provider.

To answer your question, Lyn, only individuals without overt cardiac
disease were targeted by these guidelines. Also, people < 40 years
of age with only molecular indications of genetic risk but who were
asymptomatic were excluded from the focus of these recommendations.

Thanks for your interest in this topic!
