The literature review identified 13 additional reports, totalling 19 patients. In 8 (42.1%) of patients, heart involvement was either the initial manifestation or occurred concurrently with the diagnosis of SSc. Pericardial disease (n=6) often presented as tamponade requiring emergent pericardiocentesis. Myocardial involvement (n=13) was classified as acute myocarditis (AM) in 9 (69.2%) and chronic inflammatory cardiomyopathy (CIC) in 4 (30.8%). Cardiac magnetic resonance showed late gadolinium enhancement in 9 (72.7%) and myocardial oedema in 4 (36.4%); however, both were absent in two biopsy-confirmed AM cases. Cyclophosphamide was the second most common therapy after corticosteroids. Two patients died during hospitalization, with three more deaths during long-term follow-up.</p><p><strong>Conclusion: </strong>Severe cardiac manifestations in SSc frequently occur early in the disease, presenting as tamponade or myocardial involvement. Reliance solely on imaging may lead to myocarditis underdiagnosis. Distinct clinical profiles between AM and CIC point toward separate phenotypes with unique prognostic and therapeutic considerations. Large-scale, prospective studies are essential to refine early diagnostic approaches and optimize treatment.</p>","PeriodicalId":29669,"journal":{"name":"ARP Rheumatology","volume":"5 1","pages":"15-26"},"PeriodicalIF":1.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147663257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
