Clinical Causes: Primary infection with the mumps virus, typically contracted through respiratory droplets from an infected person. Spread of the virus to the heart muscle during the course of mumps infection. In some cases, the immune response to the mumps virus may contribute to inflammation of the myocardium. Lack of vaccination or incomplete immunization against mumps increases the risk of infection and subsequent complications.

Key Symptoms: Chest pain or discomfort, which may feel like tightness or pressure. Shortness of breath, especially during exertion or physical activity. Fatigue and weakness that persist or worsen over time. Irregular heartbeat or palpitations. Fever and general malaise associated with mumps infection. Swelling or pain in the chest area. Symptoms of mumps, such as swelling of the salivary glands, especially under the jaw or around the cheeks.

Diagnosis Path: Clinical evaluation of symptoms and medical history. Blood tests to detect mumps virus antibodies or signs of inflammation. Electrocardiogram (ECG) to assess heart rhythm and detect abnormalities. Echocardiogram, an ultrasound of the heart, to evaluate heart function and look for signs of inflammation or damage. Cardiac MRI or biopsy may be considered in ambiguous cases to confirm myocarditis. Virus identification through laboratory testing can support the diagnosis but is less common.

Treatment Protocols: Supportive care is the main approach, focusing on managing symptoms. Rest and limiting physical activity to reduce strain on the heart. Medications to address symptoms, such as pain relievers or anti-inflammatory drugs. Monitoring for complications like heart failure or arrhythmias. In severe cases, hospitalization may be necessary for close observation and advanced treatments. Treating any concurrent mumps infection or symptoms to reduce the overall illness burden.
