Acute Myopericarditis caused by Human Metapneumovirus

Area of Science:

• Virology
• Infectious Diseases
• Cardiology

Background:

• Human metapneumovirus (hMPV) shares similarities with respiratory syncytial virus (RSV).
• Frequent reinfection with hMPV occurs due to incomplete immunity, particularly impacting the elderly population.
• Clinical presentations of hMPV in adults require further detailed characterization.

Purpose of the Study:

• To characterize the clinical manifestations of human metapneumovirus infection in an adult patient.
• To investigate the potential link between hMPV infection and cardiovascular complications.

Main Methods:

• Case report of a 73-year-old female presenting with acute respiratory symptoms.
• Diagnosis of human metapneumovirus infection confirmed.
• Clinical course and management, including supportive care and oxygen supplementation, were documented.

Main Results:

• The patient presented with acute dyspnea, chest discomfort, and influenza-like illness.
• Diagnosis revealed human metapneumovirus infection complicated by pneumonia and myopericarditis.
• The patient achieved complete recovery with supportive care, showing no long-term sequelae.

Conclusions:

• Human metapneumovirus infection can lead to significant clinical complications, including cardiovascular manifestations like myopericarditis.
• The elderly population may be particularly susceptible to severe outcomes and cardiac involvement from hMPV.
• This case underscores the importance of recognizing hMPV as a potential cause of serious respiratory and cardiovascular illness in adults.
