    Anabolic steroid use in weightlifters does not worsen the heart muscle thickening (myocardial hypertrophy) seen with intense training. Echocardiograms showed similar heart changes in steroid users and non-users, suggesting steroids do not enhance these effects.

    Area of Science:

    • Sports Medicine
    • Cardiology
    • Endocrinology

    Background:

    • Anabolic-androgenic steroids (AAS) are known to enhance skeletal muscle growth in athletes.
    • Weight training is associated with cardiac adaptations, including left ventricular hypertrophy (LVH).
    • The specific impact of AAS on AAS-induced or training-induced LVH remains unclear.

    Purpose of the Study:

    • To investigate the influence of anabolic steroid use on myocardial hypertrophy in bodybuilders.
    • To compare cardiac dimensions and function in steroid-using bodybuilders, non-using bodybuilders, and a control group.

    Main Methods:

    • Echocardiographic measurements of left ventricular dimensions and function were performed.
    • 15 anabolic steroid-using bodybuilders were compared to a group of non-using bodybuilders and an inactive control group.

    Main Results:

    • Both weight-lifting groups (steroid-using and non-using) exhibited increased left ventricular posterior wall (LVPW) and ventricular septal (VS) thickness compared to controls.
    • An elevated VS/LVPW ratio was observed in both weight-lifting groups.
    • No significant differences in cardiac measurements were found between the steroid-using and non-using weightlifters.

    Conclusions:

    • Weight training alone leads to significant myocardial hypertrophy.
    • Anabolic steroid use does not appear to potentiate the cardiac hypertrophy observed with intense weight training.
    • These findings suggest that the cardiac changes in these athletes are primarily driven by training stimulus.
