Here are some of the findings presented at the American Heart Association's
Scientific Session of 2006:
Commercial protective gear may not be enough to protect young athletes from
the quick blows to the chest that triggers an irregular-and fatal-heartbeat.
These events are extremely rare, and occur only when the blow strikes at a very
specific time in the cycle of the heartbeat. But it's important for parents
and educators to know that if the chest isn't fully protected, the athlete is
not fully protected from this danger.
Women who smoke early in their pregnancies, or who are exposed to second-hand
smoke early in their pregnancies, are more likely to give birth to babies who
have congenital heart defects. The heart's primary structures are formed in
the first six weeks of pregnancy, before many women know they are pregnant.
