>Left ventricular mass increased with 28.3 g (CI 14.2–42.4, P < 0.001) and was positively correlated with AAS average weekly dose. After a median recovery time of 8 months (T2), all parameters returned to baseline.
Conclusion: AAS induce left ventricular hypertrophy and impaired systolic and diastolic function in amateur strength athletes. The structural cardiac changes are positively associated with AAS dose and complete recovery occurred after AAS were discontinued.
