Abstract
Anabolic-androgenic steroids (AASs) are synthetic derivatives of testosterone and are increasingly misused to enhance muscle growth and physical performance, particularly among athletes and recreational bodybuilders. Although AASs affect multiple organ systems, their severe and potentially life-threatening complications involve the cardiovascular system. This review summarizes current knowledge on the pathophysiological mechanisms and clinical manifestations of AAS-induced cardiomyopathy. Chronic supraphysiologic AAS use promotes cardiac injury and adverse cardiac remodeling via oxidative stress, androgen receptor overactivation, RAAS dysregulation, and pro-apoptotic signaling. These changes could lead to hypertension, dyslipidemia and atherosclerosis, myocardial fibrosis and hypertrophy, arrhythmias, heart failure, and kidney injury. Vascular dysfunction, increased arterial stiffness, and a prothrombotic state further compound the cardiovascular risks. Diagnostic approaches involve biomarker evaluation, echocardiography, and cardiac magnetic resonance imaging, revealing structural and functional cardiac abnormalities such as reduced ejection fraction, concentric hypertrophy, myocardial fibrosis, and impaired diastolic function. Although cessation of AAS use may lead to partial or complete reversal of cardiac dysfunction in some individuals, others may experience irreversible myocardial damage. The reversibility appears to depend on dosage, duration of exposure, and early intervention. This review explores the cardiovascular consequences of AAS use, with a focus on the mechanisms, diagnosis, and management of AAS-induced cardiomyopathy, and underlines the importance of education and early detection.
