We describe perhaps the first reported case to the best of our knowledge of a 55-year-old Caucasian woman who presented with congestive heart failure after having a regadenoson cardiac stress test a few hours prior to presentation to the hospital. Transthoracic echocardiogram revealed reduced heart function. She had normal coronaries on cardiac catheterisation, and left ventriculography confirmed apical ballooning syndrome. She underwent guideline-directed therapy, and heart function improved in the repeat echocardiogram along with clinical resolution of symptoms.<\/jats:p>","DOI":"10.1136\/bcr-2017-221217","type":"journal-article","created":{"date-parts":[[2017,8,10]],"date-time":"2017-08-10T04:40:19Z","timestamp":1502340019000},"page":"bcr-2017-221217","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Regadenoson cardiac stress test-induced stress cardiomyopathy"],"prefix":"10.1136","volume":"2017","author":[{"given":"Jagadeesh K","family":"Kalavakunta","sequence":"first","affiliation":[{"name":"Cardiology, Borgess Medical Center\/Michigan State University, Kalamazoo, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dominika M","family":"Zoltowska","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Western Michigan University School of Medicine, Kalamazoo, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yashwant","family":"Agrawal","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Western Michigan University School of Medicine, Kalamazoo, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vishal","family":"Gupta","sequence":"additional","affiliation":[{"name":"Cardiology, Borgess Medical Center\/Michigan State University, Kalamazoo, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,8,10]]},"reference":[{"key":"2025082702003768000_2017.aug10_1.bcr-2017-221217.1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.07-0608"},{"key":"2025082702003768000_2017.aug10_1.bcr-2017-221217.2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.106.677625"},{"key":"2025082702003768000_2017.aug10_1.bcr-2017-221217.3","doi-asserted-by":"publisher","DOI":"10.1253\/jcj.64.156"},{"key":"2025082702003768000_2017.aug10_1.bcr-2017-221217.4","first-page":"53","article-title":"Takotsubo cardiomyopathy: reversible stress-induced cardiac insult - a stress protective mechanism","volume":"3","author":"Amruthlal Jain","year":"2013","journal-title":"Am J Cardiovasc Dis"},{"key":"2025082702003768000_2017.aug10_1.bcr-2017-221217.5","first-page":"125","article-title":"Left anterior descending coronary artery stenosis: in a patient with takotsubo cardiomyopathy","volume":"39","author":"Vittala","year":"2012","journal-title":"Tex Heart Inst J"},{"key":"2025082702003768000_2017.aug10_1.bcr-2017-221217.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2015.02.058"},{"key":"2025082702003768000_2017.aug10_1.bcr-2017-221217.7","unstructured":"Astellas Pharma US.
