Abstract
The consumption of androgenic steroids has a global prevalence of 6.4% in men and 1.6% in women, it is important to determine the effects of the consumption of anabolic androgenic steroids. This article aims to review myocardial structural and molecular changes produced by anabolic androgenic steroids (AAS) and the electrophysiological complications and other disorders that may occur due to consumption. A non-systematic review of the literature was carried out in the MedLine, LILACS, Clinicalkey and Google Scholar databases. 50 reference articles were included, focused on the objective of this review
In conclusion, AAS use is implicated in multiple life-threatening cardiovascular pathologies. The most frequent changes are associated with cardiac ventricular hypertrophy (VH), a sympathetic predominance that triggers arterial hypertension among other alterations
