Unusual presentations and uncommon clinical manifestations of Monkeypox Mpox in the current outbreak highlight the need to focus on cardiac symptoms of the virus. Owing to limited discussion regarding cardiac involvement in recent cases of Mpox, we conducted a scoping review to determine the range of existing research and provide a descriptive overview of the current literature on these manifestations. Records retrieved from PubMed, ScienceDirect and Google Scholar, using a two-step search strategy, were subjected to title and abstract screening, followed by full text screening of remaining articles against specified eligibility criteria.
Relevant information was extracted and summarized. Our search yielded records. Following title and abstract screening, 23 articles were retrieved for full text screening. Finally, a total of nine articles were included in this review three case series and six case reports discussing a total of 13 patients. Myocarditis was identified as the most frequently reported cardiac manifestation of Mpox. Novel clinical presentations included pharyngitis, sore throat, proctalgia, and perianal irritation.
Most patients reported chest pain as the primary symptom of cardiac system involvement. Elevated troponin was the most commonly reported investigation finding followed by an elevated C- Reactive Protein. There exists a lack of high-quality studies investigating cardiac system involvement in the current outbreak of Mpox.
We highlight the paucity of relevant data and call for further discussion to improve the understanding of cardiac manifestations of Mpox. This scoping review sheds light on the underexplored cardiac manifestations of Mpox and highlights the need for heightened awareness of cardiac symptoms in the current outbreak.
