Myocarditis Attributable to Monkeypox Virus Infection in 2 Patients, United States, 2022
Emerging Infectious Diseases
|September 30, 2022
Summary
Two healthy adults with monkeypox developed viral myocarditis, a heart inflammation. Both patients were unvaccinated and hospitalized but recovered fully after treatment.
Area of Science:
- Cardiology
- Infectious Diseases
- Viral Infections
Background:
- Monkeypox (mpox) is a viral disease that can cause serious complications.
- Viral myocarditis, inflammation of the heart muscle, is a known but rare complication of viral infections.
Purpose of the Study:
- To report cases of monkeypox-associated viral myocarditis in immunocompetent adults.
- To describe the clinical presentation, management, and outcomes of these cases.
Main Methods:
- Case report of two adult patients in the United States.
- Clinical data including symptoms, cardiac biomarkers, and vaccination status were reviewed.
Main Results:
- Two unvaccinated, immunocompetent adults with monkeypox presented with symptoms of viral myocarditis, including shortness of breath and chest pain.
- Elevated cardiac biomarkers confirmed myocardial injury.
- Both patients were hospitalized but recovered without immediate complications and were discharged home.
Conclusions:
- Monkeypox can cause viral myocarditis even in healthy adults.
- Prompt diagnosis and supportive care are crucial for managing this complication.
- Further research is needed to understand the long-term cardiac implications of monkeypox infection.

Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Myocarditis is an inflammatory condition of the myocardium requiring meticulous nursing management for optimal patient outcomes. Effective management begins with a thorough assessment of the patient's medical history, paying close attention to past infections, autoimmune disorders, travel history, and exposure to toxins or drugs. Recent viral infections and systemic diseases are particularly relevant due to their potential role in triggering myocarditis.Physical Examination and MonitoringThe...

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
