On the fourth postoperative day (POD), the patient presented to the emergency department with severe symptomatic hypocalcaemia. ECG findings were in keeping with inferior\u2013posterior ST-elevation myocardial infarction (STEMI); however, he was asymptomatic with no chest pain. Biochemistry revealed elevated serial troponin levels. Coronary angiogram and transthoracic echocardiogram were normal, suggesting coronary vasospasm, mimicking STEMI on ECG because of severe hypocalcaemia post parathyroidectomy. This is an uncommon and unreported complication of parathyroid surgery. The patient was successfully managed with intravenous calcium and discharged on oral calcium replacement on the tenth POD.<\/jats:p>","DOI":"10.1136\/bcr-2021-247919","type":"journal-article","created":{"date-parts":[[2022,5,23]],"date-time":"2022-05-23T11:29:28Z","timestamp":1653305368000},"page":"e247919","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Case of coronary vasospasm caused by hypocalcaemia post parathyroidectomy mimicking ST-elevation myocardial infarction"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8230-0212","authenticated-orcid":false,"given":"Aiswarya","family":"Ajith","sequence":"first","affiliation":[{"name":"ENT department, Galway University Hospital, Galway, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mel","family":"Corbett","sequence":"additional","affiliation":[{"name":"ENT department, Galway University Hospital, Galway, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Garry","sequence":"additional","affiliation":[{"name":"ENT department, Galway University Hospital, Galway, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Orla","family":"Young","sequence":"additional","affiliation":[{"name":"ENT department, Galway University Hospital, Galway, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,4,21]]},"reference":[{"key":"2025082722422004000_15.4.e247919.1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMcp032200"},{"key":"2025082722422004000_15.4.e247919.2","doi-asserted-by":"crossref","first-page":"674","DOI":"10.4158\/EP14462.DSC","article-title":"American association of clinical endocrinologists and American college of endocrinology disease state clinical review: Postoperative hypoparathyroidism - Definitions and management","volume":"21","author":"Stack","year":"2015","journal-title":"Endocrine Practice"},{"key":"2025082722422004000_15.4.e247919.3","doi-asserted-by":"crossref","first-page":"959","DOI":"10.1001\/jamasurg.2016.2310","article-title":"The American association of endocrine surgeons guidelines for definitive management of primary hyperparathyroidism","volume":"151","author":"Wilhelm","year":"2016","journal-title":"JAMA Surg"},{"key":"2025082722422004000_15.4.e247919.4","doi-asserted-by":"crossref","first-page":"352","DOI":"10.1177\/000313481207800347","article-title":"Predictive factors for postoperative severe hypocalcaemia after parathyroidectomy for primary hyperparathyroidism","volume":"78","author":"Crea","year":"2012","journal-title":"Am Surg"},{"key":"2025082722422004000_15.4.e247919.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamcollsurg.2010.03.019"},{"key":"2025082722422004000_15.4.e247919.6","doi-asserted-by":"crossref","first-page":"2310","DOI":"10.1245\/s10434-016-5190-7","article-title":"Delayed calcium normalization after presumed curative parathyroidectomy is not associated with the development of persistent or recurrent primary hyperparathyroidism","volume":"23","author":"Lai","year":"2016","journal-title":"Ann Surg Oncol"},{"key":"2025082722422004000_15.4.e247919.7","doi-asserted-by":"publisher","DOI":"10.1089\/thy.2006.16.259"},{"key":"2025082722422004000_15.4.e247919.8","first-page":"827","article-title":"Relation of postoperative hypocalcemia to operative techniques: deleterious effect of excessive use of parathyroid biopsy","volume":"92","author":"Kaplan","year":"1982","journal-title":"Surgery"},{"key":"2025082722422004000_15.4.e247919.9","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.135.2.142"},{"key":"2025082722422004000_15.4.e247919.10","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-200211000-00001"},{"key":"2025082722422004000_15.4.e247919.11","doi-asserted-by":"crossref","first-page":"993","DOI":"10.1016\/S0039-6060(98)70040-6","article-title":"Primary and reoperative parathyroid operations in hyperparathyroidism of multiple endocrine neoplasia type 1","volume":"124","author":"Hellman","year":"1998","journal-title":"Surgery"},{"key":"2025082722422004000_15.4.e247919.12","doi-asserted-by":"crossref","first-page":"7","DOI":"10.4158\/EP10290.RA","article-title":"Subtotal parathyroidectomy for primary hyperparathyroidism","volume":"17","author":"TWF","year":"2011","journal-title":"Endocr.
