Electrocardiographic and morphological cardiac remodeling in competitive female athletes - a scoping review. | LitMetric

AI Article Synopsis

  • The study aims to quantitatively analyze exercise-induced cardiac remodeling in female athletes, focusing on data from various imaging techniques and ECG results.
  • It included 31 peer-reviewed articles with nearly 5,000 female athletes, highlighting prevalent ECG findings like LV hypertrophy and specific echocardiography metrics showing dilated heart chambers compared to population norms.
  • The results indicate that female athletes exhibit unique electrical and morphological cardiac changes, reinforcing the need for further research on sex-specific cardiac responses in athletic populations.

Article Abstract

Aims: To quantitatively analyse exercise-induced cardiac remodeling (EICR) data in female athletes.

Methods: This scoping review included from the databases Medline, Embase, and Google Scholar, peer-reviewed original English-language articles on female athlete-populations aged ≥18 years containing data on electrocardiography (ECG), echocardiography or cardiac magnetic resonance (CMR), and excluded athletes with cardiovascular conditions. From the extracted ECG data, we calculated prevalence percentages, and from the imaging data we compared the results with the upper reference limits of the general female population (URL).

Results: We included 31 articles comprising 4,896 female athletes, aged mean 22.2±4.6 years. On ECG (n=889), most prevalent findings were increased QRS voltages for LV hypertrophy (LVH, n=97), J-point elevation (JPE, n=108), and T-wave inversion (TWI, n=104). On echocardiography (n=4,644), we found increased mean of means BSA-indexed volumes for the LV 67.3 mL/m2 (95%CI 66.8-67.8; URL=61) and right ventricle (RV) 82.7 mL/m2 (95%CI 79.5-86.0; URL=74), while atrial volumes, septal wall thickness and LV mass were within the upper reference limits of the general population (URL). On CMR (n=309), the mean of means volumes of LA (62.0 mL/m2, 95%CI 58.8-65.2; URL=61), LV (103.4 mL/m2, 95%Ci 101.8-105.0; URL=96), and RV (105.3 mL/m2, 95%CI 103.3-110.6; URL=107.2) were >URL.

Conclusion: Female athletes demonstrate distinct features of electrical (increased QRS voltages for LVH, JPE and TWI) and morphological EICR (biventricular dilatation). On CMR, LA was borderline dilated. Extensive studies on female athletes are needed to understand sex specific EICR.
