In adults and adolescents, the condition frequently goes underdiagnosed because its presentation is typically non-specific and can mimic other, more common respiratory illnesses. Although complications affecting the respiratory system are well documented in the literature, cardiac involvement, especially in the form of acute myocarditis, remains a very rare and under-reported condition. Historically, efforts to establish a definitive connection between pertussis and cardiac dysfunction have been limited by the absence of sensitive and specific diagnostic modalities. With advances in cardiac MRI, this case presents an unvaccinated teenager diagnosed with acute myocarditis linked to a pertussis, underscoring the utility of modern imaging modalities and emphasising the importance of vaccination and clinical vigilance in atypical respiratory presentations.<\/jats:p>","DOI":"10.1136\/bcr-2025-267804","type":"journal-article","created":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T13:15:19Z","timestamp":1764249319000},"page":"e267804","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond the cough: acute myocarditis following pertussis in an adolescent"],"prefix":"10.1136","volume":"18","author":[{"given":"Maethas","family":"Panyawongkhanti","sequence":"first","affiliation":[{"name":"Division of Cardiovascular Medicine, Department of Medicine, Faculty of Medicine, Chulalongkorn University, King Chulalongkorn Memorial Hospital, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sopida","family":"Thammamonkonchai","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Medicine, Department of Medicine, Faculty of Medicine, Chulalongkorn University, King Chulalongkorn Memorial Hospital, Bangkok, Thailand"},{"name":"Division of Internal Medicine, Faculty of Medicine, Burapha University, Chonburi, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Napon","family":"Hiranburana","sequence":"additional","affiliation":[{"name":"HIV-NAT, Thai Red Cross AIDS Research Center, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pairoj","family":"Chattranukulchai","sequence":"additional","affiliation":[{"name":"Cardiovascular Medicine, Chulalongkorn University Faculty of Medicine, Bangkok, Thailand"},{"name":"Midicine, King Chulalongkorn Memorial Hospital, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,11,27]]},"reference":[{"key":"2025112705151232000_18.11.e267804.1","doi-asserted-by":"crossref","unstructured":"Nieves DJ , Heininger U .
