A 53-year-old bodybuilder presented with 3 months of exertional dyspnoea. Physical examination showed tachycardia and pan-systolic murmur; an echocardiogram showed a left ventricular ejection fraction (EF) of 15%. Evaluations included normal coronary angiogram, iron panel and thyroid studies, a negative viral panel (human immunodeficiency virus, Lyme disease, and hepatitis), and urine toxicology. He admitted to intramuscular anabolic steroid use; his testosterone level was 30 160.0 ng\/dL (normal 280\u20131100 ng\/dL). In addition to discontinuation of anabolic steroid use, he was treated with guideline-directed heart failure medical therapy. Repeat echocardiogram at 6 months showed an EF of 54% and normalized testosterone level of 603.7 ng\/dL. Anabolic steroid use is a rare, reversible cause of cardiomyopathy in young, otherwise healthy athletes; a high index of suspicion is required to prevent potentially fatal side effects.<\/jats:p>","DOI":"10.1002\/ehf2.12494","type":"journal-article","created":{"date-parts":[[2019,7,9]],"date-time":"2019-07-09T05:44:46Z","timestamp":1562651086000},"page":"1000-1004","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Strong Muscles, Weak Heart: Testosterone-Induced Cardiomyopathy"],"prefix":"10.1093","volume":"6","author":[{"given":"Sarah","family":"Doleeb","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Aurora Sinai\/Aurora St. Luke's Medical Centers , 2801 W.
