Human metapneumovirus infection can cause acute myopericarditis in elderly patients, which may resolve with supportive care.
May support conservative care for hMPV myopericarditis in elderly; leaves open questions on incidence and risk stratification.
Human metapneumovirus is known to be similar to respiratory syncytial virus. Because of an incomplete protective immune response to new genotypes, re-infection occurs frequently, especially in the elderly. However, the clinical manifestations of human metapneumovirus need to be further characterized in adults. A 73-year-old woman presented to the emergency room with acute dyspnea, chest discomfort and influenza-like illness. The patient was diagnosed with human metapneumovirus infection, complicated by pneumonia and myopericarditis. With supportive care including oxygen supplementation, the patient recovered completely without any serious sequelae. Human metapneumovirus infection may contribute to the development of cardiovascular manifestations, particularly in the elderly population.

Choi et al. (2016) conducted a case report in Acute Myopericarditis caused by Human Metapneumovirus (n=1). Human metapneumovirus infection was evaluated on Clinical outcome. Human metapneumovirus infection in a 73-year-old woman was complicated by acute myopericarditis and pneumonia, which completely resolved with supportive care.
