Gender differences in diastolic function are evident in youth. Girls exhibit higher relative wall thickness and altered early to late peak filling velocity ratios, suggesting potential early cardiovascular changes.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Cardiovascular Physiology

Background:

  • Diastolic dysfunction can manifest early in congestive heart failure.
  • Understanding gender-specific influences on cardiac function in youth is crucial.

Purpose of the Study:

  • To investigate the influence of gender on diastolic function in adolescents.
  • To identify potential early indicators of cardiovascular differences between genders.

Main Methods:

  • Studied 121 normotensive adolescents (53 girls, 68 boys) aged 14-18.
  • Collected demographic, hemodynamic, and Doppler-derived diastolic function indices.
  • Analyzed the early to late peak filling velocity (E/A) ratio and isovolumetric relaxation time (IVRT).

Main Results:

Related Experiment Videos

  • Girls presented with higher relative wall thickness (RWT) and a lower E/A ratio compared to boys.
  • Girls also showed a shorter isovolumetric relaxation time (IVRT).
  • Gender was a significant predictor for both E/A ratio and IVRT.

Conclusions:

  • Gender disparities in diastolic function are present in adolescents.
  • Girls exhibit specific echocardiographic markers suggestive of altered diastolic function.
  • Further research is needed to understand the long-term cardiovascular implications of these gender differences.
