1

This cross-sectional study included 54 resistance-training women: 20 current AAS users, 17 former users, and 17 never-users.
2

Mean myocardial flow reserve and the prevalence of clinically or subclinically impaired reserve did not differ among the three groups.
3

Among former AAS users, longer cumulative exposure was associated with lower myocardial flow reserve, including after adjustment for age and time since cessation.
4

Resting myocardial blood flow was lower in current AAS users than in control participants, while former users’ values did not differ significantly from controls.
5

The small sample and cross-sectional design limit causal inference; overall myocardial flow reserve did not differ by AAS-use history.
