Anabolic steroid abuse in bodybuilders is linked to impaired diastolic function, despite normal systolic function. This study highlights potential cardiac risks associated with performance-enhancing drug use.

Area of Science:

  • Cardiology
  • Sports Medicine
  • Pharmacology

Background:

  • Anabolic steroid use is prevalent among athletes for performance enhancement.
  • Known side effects include cardiac hypertrophy.
  • The impact on left ventricular function requires further elucidation.

Purpose of the Study:

  • To investigate whether anabolic steroids induce alterations in left ventricular function.
  • To compare cardiac function in anabolic steroid users, non-users, and sedentary controls.

Main Methods:

  • Standard echocardiography and cardiac tissue Doppler imaging were employed.
  • 14 male anabolic steroid users, 11 steroid-free athletes, and 15 controls were studied.
  • Analysis focused on left ventricular mass, diastolic filling parameters, and myocardial velocities.

Related Experiment Videos

Main Results:

  • Anabolic steroid users exhibited increased left ventricular muscle mass index.
  • No significant differences were observed in peak transmitral blood flow velocities.
  • Users showed significantly reduced myocardial velocities during early and late ventricular filling (diastolic function) and a lower velocity gradient during myocardial E-wave.

Conclusions:

  • Anabolic steroid abuse in strength athletes is associated with negative alterations in diastolic function.
  • Systolic function remained unaffected.
  • These findings suggest potential cardiac dysfunction in anabolic steroid users.
