Summary

Sudden cardiac death in athletes is rare but striking. Echocardiography is more effective than stress tests in identifying at-risk individuals for sudden cardiac death.

Area of Science:

  • Sports medicine
  • Cardiology
  • Public health

Background:

  • Sudden death in athletes, though rare, is a significant concern due to the seemingly healthy nature of the affected individuals.
  • Age is a critical factor, with different underlying causes of sudden death prevalent in different age groups.

Purpose of the Study:

  • To assess the incidence of sudden death in athletes in France.
  • To identify the primary causes of sudden cardiac death in athletes across different age demographics.
  • To evaluate the effectiveness of diagnostic tests in identifying athletes at risk.

Main Methods:

  • Analysis of sudden death incidence in the French athletic population.
  • Categorization of causes of sudden death based on age.
  • Comparison of the positive predictive values of echocardiography and traditional stress tests.

Main Results:

  • Approximately 1 in 10,000 athletes experience sudden death annually in France.
  • Coronary heart disease is the leading cause in athletes over 35, while hypertrophic cardiomyopathy, congenital heart disease, and aortic rupture are more common in younger athletes.
  • Echocardiography demonstrates a high positive predictive value for risk detection, significantly outperforming traditional stress tests.

Conclusions:

  • Sudden cardiac death in athletes is a distinct public health issue.
  • Diagnostic strategies should prioritize echocardiography for identifying at-risk athletes.
  • Age-specific etiological factors necessitate tailored screening approaches.
