Incidence
! Sudden cardiac death (SCD) is the leading cause of death in athletes.
! SCD incidence rate " 1:50,000 college athletes " 1:50,000–1:80,000 high school athletes.
! Possible higher risk: " Males, African- Americans basketball
players. Harmon 2014
Death in NCAA Athletes
! 10 years, 4,052,369 athletes
! suicide + drugs 1.3/100,000 athlete participation-years (5 deaths/yr)
! CV disease, 1.2/100,000 athlete participation-years (4 deaths/yr). " 5 times greater in African-
American athletes
Maron 2014
MN high school experience
! Minnesota HS Athletes 1993–2012 ! 1,666,509 unduplicated athletes participating
in ≥1 sports. ! 4 SCDs (2 cross country, 1 basketball, 1
wrestling), all male ! H&P PPE every 3 years ! SCD 0.24 per 100,000 athlete-years over 19
years & 0.11 per 100,000 athlete-years over the past decade

The “athletic heart syndrome”
! Sinus bradycardia (80%+ vs. 19%) ! Sinus arrhythmia (50%+ vs. 9%)
" AV blocks " Junctional rhythms " PVCs - up to 100/d " STTW changes - repolarization
! Voltage changes (85%LVH by voltage)
Incidence of EKG abnormalities
7,764 nonathletes 4,081 athletes Training-related changes
49.1% 87.4%
Potentially pathological 21.8% 33%
! 14 to 35 yo ! 2010 European Society of Cardiology position paper ! Nonathletes
" QTc interval abnormalities (52%) of group 2 changes, " T-wave inversions constituted 11%.
! Males & African/Afro-Caribbean ethnicity strongest association with potentially pathological

Causes of death in young person (< 35 y.o.)
Motor vehicle accidents 14,700 deaths/yr
Drowning 1500
Accidental shooting 500

Society recommendations
! American Heart Assoc: H&P without routine ECG
! American Coll of Preventive Med: H&P without routine ECG
! European Society of Cardiologists: H&P & ECG.
! International Olympic Committee: H&P & ECG.
! American Coll of Sports Med: H&P without routine ECG
Horizon Cardiac MRI?
! Mangold 2013 " 95 endurance athletes " Abnormal findings in 6.3%
# 1 benign coronary anomaly # 1 coronary anomaly of unknown significance # 2 with finding of remote myocarditis # 1 with recovering myocarditis from recent EBV # None restricted @ 2 years all still asymptomatic
! Angelini 2013
Summary
! CV screening in athletes is still controversial
! Screening tests are becoming more economical " Less false positives
