up ? This is THE stephane ANDRE. With my training, I’m
interested in biomechanics to avoid injuries. I read « Sport
Medicine Media Guide » and I learned some good stuff.
cardiac death (SCD) is an extremely rare event. The most common
reason for cardiac death related to sports is the cardiomyopathy
hypertrophic, an abnormal enlargement of cardiac muscle. It’s a rare
heart disease that predispose a person of SCD because of physical
cordis is another reason for SCD. It’s a direct trauma to the chest
at a specific moment in the cardiac cycle and this trauma triggers a
dangerous arrtyhmia (abnormal rhythm) of electrical system of the
heart. A commotio cordis usually arrives in sports where a blunt
projectile, such as baseball ball or hockey puck, hits the athlete’s
arrhythmias that threaten the lives of young athletes are very
difficult to treat. The immediate use of AED (automated external
defibrillator) can provide an advantage.
the only way to prevent death from hypertrophic cardiomyopathy is to
identify the disease and recommend the athlete avoid any strenuous
activities. Cardiac ultrasound can diagnose this condition. Some
experts have called for the screening of athletes with ultrasound or
electrocardiograms (EKG), although this screening is controversial
because of the high cost and scarcity of this condition.
athletes with cardiac symptoms such as dizziness, fatigue, shortness
of breath in relation to physical activity, palpitations, convulsions
and especially syncope (fainting) must stop the competitions and must
do deeper tests.
addition, a family history of cardiac abnormalities justifies a
complete cardiac evaluation. Especially a known parent with
hypertrophic cardiomyopathy or a history unexplained sudden death in
a family member.
is the creation of different forms of protection for the chest and
pads, but unfortunately no method has prevented this tragic event.
The rules regularly change in the sport and some times to try to
avoid commotio cordis. For example in baseball and softball, it’s the
limitation of the use of aluminium bat. This rule can protect the
pitcher by decreasing the speed of the ball after contact with the
bat. There are other rules too, such as using a softer ball and
teaching players to turn their chest when the ball is hit by the bat.
Fortunately, SCD is extremely rare in the sport. For the majority of people do sports to cardiac benefits.
In young athetes, the most common causes of SCD are 25-30% hypertrophic cardiomyopathy and 20% commotio cordis.
Coronary artery abnormalities are the cause of 14% of SCD in athletes.
Marc-Vivian Foe, a Cameroonian soccer star had a sudden cardiac death during a match in 2003.
