Goals Background Clinical evaluation Clinical evaluation Diseases Testing
Athletes Are Challenging Stakes are high for diagnosis. CV system may be pushed to limit CV system may be pushed to limit. Consequences of misdiagnosis are
potentially devastatingpotentially devastating. < 30 years – congenital/structural abnl > 30 years – coronary artery disease
Difficult Problem Estimation of the incidence of sudden death
in the young in the United States is critical to understand the scope of the problem
Need to know the actual incidence to make recommendations as to the cost-effectiveness
Implementing any strategy to reduce the i idincidence
Devise appropriate preventative strategies Inform policy makers who allocate resources
Risk of Sudden Death 1 in 200,000 athletes will die suddenly. Annual U S Death rate 15 cases per 3 Annual U.S. Death rate 15 cases per 3
million high school athletes in sports.Male:female=5:1 Male:female=5:1.
Mortality Rates U.S. (2000)Automobile related deaths 15,000-18,000
Young adult homicide 6,000
S i id 5 000Suicide 5,000

Sudden Cardiac Death: Can YouSudden Cardiac Death: Can You Identify the Patient at Risk?
“In the fields of observationIn the fields of observation, chance only favors the mind
that is prepared ”that is prepared.” Louis Pasteur
Pre-participation screening May identify <10% of athletes at risk of
SCDSCD Physical Exam is typically normal
History of prior exercise related History of prior exercise related symptoms is frequently present
? What questions are important?
Identification of Risk Factors: Personal History Syncope during exercise Frequent, severe dizziness or recurrentFrequent, severe dizziness or recurrent
syncope Chest pain during exerciseChest pain during exercise Prolonged “flu” Previous Kawasaki disease Previous Kawasaki disease Palpitations
S i Seizures
How often are symptoms y ppresent? Exercise related syncope in 20-25% Dizziness in 16% Dizziness in 16% Chest pain in 6% “Seizure” may be only symptom of
prolonged QT syndrome
Identification of Risk Factors: Family History Sudden death at <30 years of age Long QT syndrome Long QT syndrome Hypertrophic cardiomyopathy Marfan syndrome Arrhythmogenic right ventricular
dysplasia Very early-onset coronary artery e y ea y o set co o a y a te y
