Sport Type Alone Does Not Reliably Predict Distinct Cardiac Phenotypes in Athletes

Eur J Prev CardiolPublished

  • Cross-sectional study

Authors' conclusion

ESC and AHA/ACC sport classifications capture population-level remodelling but cannot reliably be used to predict individual cardiac phenotypes.

Study context

Population
Elite athletes (310 women, 48 disciplines) and controls
Participants
1,024 athletes
Exposure
Athletes vs Controls
  • Athletesn = 775
  • Controlsn = 249reference
Outcome
Whether sport classifications predict CMR-determined cardiac remodelling phenotypes (population level R2; individual level balanced accuracy)

Main finding

As reported in the abstract

Prediction of CMR remodelling phenotype by sport classification
ESC categories vs RVEDV, R2
0.170
RV remodelling prevalence, skill to endurance
8.3%-62.2%
RV remodelling, OR per ESC category (P<0.001)
3.82
AHA/ACC static component vs LV mass, R2
0.077
AHA/ACC dynamic component vs RVEDV, R2
0.072
Balanced accuracy, ESC (vs 25% chance)
34.2%
Balanced accuracy, AHA/ACC (vs 25% chance)
37.7%

Observational data: associations, not effects.
