Reduced breath sounds were noted over the right lung. Initial ECG showed ST-segment elevation in leads V3-V5, and focused echocardiography showed septal wall hypokinesia, suggestive of myocardial infarction. Fibrinolysis therapy was started due to percutaneous coronary intervention service limitation. Despite treatment, there were no signs of improvement. A right-sided pneumothorax was detected on CXR done near the end of fibrinolysis. Consequently, a right chest drain was performed. Patient\u2019s symptoms, ST elevation and hypokinetic left ventricle wall resolved afterwards. A talc pleurodesis was done prior to discharge with no evidence of pneumothorax recurrence on follow-up. This case highlights the atypical presentation of pneumothorax, emphasising the importance of comprehensive clinical assessment, including lung point-of-care ultrasound, in emergency settings to expedite diagnosis, prevent inappropriate treatment and improve patient outcomes.<\/jats:p>","DOI":"10.1136\/bcr-2025-271342","type":"journal-article","created":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T17:25:33Z","timestamp":1774977933000},"page":"e271342","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond the obvious: pneumothorax masquerading as a cardiac emergency"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-2165-3594","authenticated-orcid":false,"given":"Puteri Nur Athirah","family":"Megat Mohamad Aminuddin","sequence":"first","affiliation":[{"name":"Respiratory Unit, Faculty of Medicine Hospital Canselor Tuanku Muhriz, Cheras, Federal Territory of Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1721-6329","authenticated-orcid":false,"given":"Mohd Jazman","family":"Che Rahim","sequence":"additional","affiliation":[{"name":"Internal Medicine Department, Universiti Sains Malaysia Health Campus, Kota Bahru, Kelantan, Malaysia"},{"name":"Hospital Pakar USM, Kota Bharu, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mas Fazlin","family":"Mohamad Jailaini","sequence":"additional","affiliation":[{"name":"Respiratory Unit, Faculty of Medicine Hospital Canselor Tuanku Muhriz, Cheras, Federal Territory of Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed Faisal","family":"Abdul Hamid","sequence":"additional","affiliation":[{"name":"Respiratory Unit, Faculty of Medicine Hospital Canselor Tuanku Muhriz, Cheras, Federal Territory of Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,3,31]]},"reference":[{"key":"2026033110252296000_19.3.e271342.1","doi-asserted-by":"crossref","DOI":"10.5339\/qmj.2022.56","article-title":"Demographics, clinical characteristics, and recurrence rate of patients with primary spontaneous pneumothorax at a tertiary care center in Qatar","volume":"2022","author":"Ahmad Khan","year":"2022","journal-title":"Qatar Med J"},{"key":"2026033110252296000_19.3.e271342.2","first-page":"361","article-title":"Electrocardiographic changes in patients with spontaneous pneumothorax","volume":"59 Suppl 6","author":"Krenke","year":"2008","journal-title":"J Physiol Pharmacol"},{"key":"2026033110252296000_19.3.e271342.3","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1970.00310010153019"},{"key":"2026033110252296000_19.3.e271342.4","doi-asserted-by":"publisher","DOI":"10.1378\/chest.86.1.143"},{"key":"2026033110252296000_19.3.e271342.5","doi-asserted-by":"publisher","DOI":"10.1097\/00003246-200005000-00065"},{"key":"2026033110252296000_19.3.e271342.6","doi-asserted-by":"crossref","DOI":"10.1097\/MD.0000000000015190","article-title":"Tension pneumothorax-induced Takotsubo syndrome: A case report","volume":"98","author":"Chen","year":"2019","journal-title":"Medicine (Baltimore)"},{"key":"2026033110252296000_19.3.e271342.7","doi-asserted-by":"crossref","first-page":"254","DOI":"10.5090\/kjtcs.2018.51.4.254","article-title":"Thoracic Scoliosis in Patients with Primary Spontaneous Pneumothorax","volume":"51","author":"Lee","year":"2018","journal-title":"Korean J Thorac Cardiovasc Surg"},{"key":"2026033110252296000_19.3.e271342.8","doi-asserted-by":"publisher","DOI":"10.1136\/thorax-2022-219698"},{"key":"2026033110252296000_19.3.e271342.9","doi-asserted-by":"crossref","first-page":"269","DOI":"10.1001\/jamasurg.2021.7050","article-title":"Comprehensive Review of Chest Tube Management: A Review","volume":"157","author":"Anderson","year":"2022","journal-title":"JAMA Surg"},{"key":"2026033110252296000_19.3.e271342.10","doi-asserted-by":"crossref","unstructured":"Marcoux, M.D. M , Slate, M.D. J , Majid, M.D. A .
