Decompensated Non-Ischemic Cardiomyopathy Induced by Anabolic-Androgenic Steroid Abuse

A 30-year-old male presented to the emergency department with dyspnea, fatigue, orthopnea, and paroxysmal nocturnal dyspnea for the past three months. The patient admitted to anabolic steroid use for the past 11 years. Transthoracic echocardiography was significant for severely dilated left ventricle, diffuse hypokinesis, ejection fraction < 15%, and grade II diastolic dysfunction. The patient was diagnosed with decompensated, non-ischemic cardiomyopathy stage C, and New York Heart Classification (NYHA) class III > IV, likely from use of anabolic steroids, after a negative workup for other etiologies. On follow-up after continuation of guideline-directed medical therapy, the patient demonstrated improved heart failure status (NYHA class I > II). Cardiomyopathy is a rare but important adverse effect of anabolic steroids to consider.
