Introduction:
Anabolic-androgenic steroids (AAS), a synthetic derivate of testosterone, have become a popular drug among athletes and bodybuilders to enhance muscle mass and improve the athletic performance. Many pathological effects such as hepatic and endocrine dysfunction, behavioural changes and cardiovascular complications have been reported.
Case Report:
Within these ast ones, we find an increase in left ventricular muscle mass, concentric myocardial hypertrophy, left ventricular diastolic dysfunction, arterial hypertension, prothrombotic effects, changes in the concentration of cholesterol levels, particularly a reduction in HDL cholesterol concentration, myocardial infarctions in relation to endothelial dysfunction, vasospasms or thrombosis and sudden cardiac death.
Discussion:
We report the case of a 32-year-old patient with a history of arterial hypertension, depressive syndrome and consumption of cocaine, amphetamines and AAS who developed severe left ventricular systolic dysfunction and myocardial hypertrophy with signs of heart failure and peripheral arterial embolism.

Stimulants
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral...
Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
