Inflammation of the heart muscle or myocarditis
Inflammation of the heart muscle or myocarditis is a disease of the heart muscle (myocardium), most often caused by a viral infection, bacteria, parasites, taking certain medications, drugs, poisoning, contact with heavy metals or may be the result of other diseases. Coxsackie B. virus infection, which is associated with colds and meningitis, is one of the most well-known causes of heart muscle disease. Influenza infection that has not been treated or bacterial diseases such as diphtheria and borreliosis can be causes of myocarditis. A significant number of patients are also observed with the outbreak of the COVID-19 pandemic. Inflammation of the heart muscle can occur after a fungal infection, due to autoimmune disease or radiation therapy, connective tissue disease, hepatitis, lupus.
A diseased heart is unable to supply the body with enough blood, the heart is increasingly depleted, inflammation leads to enlargement and weakening of the heart, and blood clots can form in the heart, or heart attack or stroke. This inflammation can lead to dangerous heart failure, sudden cardiac death. Myocarditis is a serious disease that is not easy to diagnose because in many cases the symptoms do not appear or the symptoms are nonspecific and may indicate other diseases. In general, heart disease is most commonly associated with the elderly, however inflammation of the heart muscle it occurs in all ages and in both sexes, often in young, healthy people, and in the years from puberty to the early thirties, while the vulnerable population and pregnant women, children and people with weakened immunity.
Symptoms and diagnosis of myocarditis (inflammation of the heart muscle)
Symptoms of myocarditis can be mild, inconspicuous so-called. asymptomatic inflammation, completely nonspecific, such as when a person feels unwell with a viral infection, but inflammation of the heart muscle it can be a complication with the rapid development of the disease, and cause severe life-threatening heart problems. Inflammation of the heart muscle has the following symptoms: fatigue, intolerance to physical exertion, shortness of breath, chest pain that intensifies on inhalation, a feeling of suffocation, cardiac arrhythmia, fluid retention, swelling of the legs, ankles and feet. Headaches, muscle and joint pain, malaise, shortness of breath, feeling hot, sweating, and sometimes loss of consciousness also occur. In addition to the possible listed symptoms, the disease may be accompanied by loss of appetite and weight loss.

Body temperature of 38 ° C and above for the past 30 days, especially if accompanied by signs of respiratory or gastrointestinal infection, may also be a feature that increases the suspicion of myocarditis.

In the diagnosis of suspected forms of myocarditis, chest X-rays, heart ultrasound, ECG, laboratory tests, magnetic resonance imaging, and in certain situations myocardial biopsy are performed.

If necessary, medications are prescribed to regulate heart function and help eliminate excess fluid. In most cases, patients with myocarditis will be hospitalized. In the most severe and most dangerous but very rare cases of myocarditis, an urgent heart transplant may be needed.
