The patient presented with a 4-month history of shortness of breath on exertion, orthopnoea and weight loss. Transthoracic echocardiography demonstrated severely impaired biventricular systolic function and bilateral ventricular thrombi, subsequently confirmed on cardiac magnetic resonance imaging, which found in addition no oedema, inflammation or focal fibrosis. Blood tests, renal ultrasound and subsequent abdominal MRI demonstrated severe renal failure caused by a chronic obstructive uropathy, long-standing and previously undiagnosed. There was no significant past medical, family or social history other than excessive intake of an energy drink. This case report adds to the growing concern in the literature about the potential cardiotoxic effects of energy drinks, which should be considered when assessing young patients presenting with a non-ischaemic dilated cardiomyopathy.<\/jats:p>","DOI":"10.1136\/bcr-2020-239370","type":"journal-article","created":{"date-parts":[[2021,4,15]],"date-time":"2021-04-15T20:01:55Z","timestamp":1618516915000},"page":"e239370","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":19,"title":["Energy drink-induced cardiomyopathy"],"prefix":"10.1136","volume":"14","author":[{"given":"Gracie","family":"Fisk","sequence":"first","affiliation":[{"name":"Department of Cardiology and Division of Cardiovascular Sciences, Guy's and St Thomas' NHS Foundation Trust, St Thomas' Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Hammond-Haley","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Division of Cardiovascular Sciences, Guy's and St Thomas' NHS Foundation Trust, St Thomas' Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8700-1545","authenticated-orcid":false,"given":"Andrew","family":"D'Silva","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Division of Cardiovascular Sciences, Guy's and St Thomas' NHS Foundation Trust, St Thomas' Hospital, London, UK"},{"name":"School of Cardiovascular Medicine and Sciences, King\u2019s College London, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,4,15]]},"reference":[{"key":"2025082709013232000_14.4.e239370.1","doi-asserted-by":"crossref","first-page":"104","DOI":"10.3390\/beverages1020104","article-title":"Cardiovascular complications of energy drinks","volume":"1","author":"Higgins","year":"2015","journal-title":"Beverages"},{"key":"2025082709013232000_14.4.e239370.2","doi-asserted-by":"crossref","first-page":"225","DOI":"10.3389\/fpubh.2017.00225","article-title":"Health effects and public health concerns of energy drink consumption in the United States: a mini-review","volume":"5","author":"Al-Shaar","year":"2017","journal-title":"Front Public Health"},{"key":"2025082709013232000_14.4.e239370.3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200004133421502"},{"key":"2025082709013232000_14.4.e239370.4","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehw128"},{"key":"2025082709013232000_14.4.e239370.5","doi-asserted-by":"publisher","DOI":"10.1136\/heartjnl-2016-309783"},{"key":"2025082709013232000_14.4.e239370.6","doi-asserted-by":"crossref","first-page":"24","DOI":"10.1097\/01.JAA.0000654368.35241.fc","article-title":"Takotsubo cardiomyopathy: review of broken heart syndrome","volume":"33","author":"Boyd","year":"2020","journal-title":"JAAPA"},{"key":"2025082709013232000_14.4.e239370.7","doi-asserted-by":"publisher","DOI":"10.1007\/s00059-010-3339-x"},{"key":"2025082709013232000_14.4.e239370.8","doi-asserted-by":"crossref","first-page":"2032","DOI":"10.1093\/eurheartj\/ehy076","article-title":"International expert consensus document on Takotsubo syndrome (Part I): clinical characteristics, diagnostic criteria, and pathophysiology","volume":"39","author":"Ghadri","year":"2018","journal-title":"Eur Heart J"},{"key":"2025082709013232000_14.4.e239370.9","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2007.11.008"},{"key":"2025082709013232000_14.4.e239370.10","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.111.057505"},{"key":"2025082709013232000_14.4.e239370.11","first-page":"317.e1","article-title":"Do energy drinks really give you wings?
