Many people often ask if my myocarditis is contagious. Actually, myocarditis is a focal inflammatory lesion of the myocardium or a diffuse inflammatory disease of the entire myocardium. It is an inflammatory disease of the myocardium. Based on the cause, we classify it into infectious and non-infectious types. The infectious type is mostly caused by viruses, such as Coxsackievirus B, or by bacteria, while non-infectious type is caused by allergies. Generally, they are not contagious.

What to eat for myocarditis?

For patients who already have myocarditis, what should we feed them? This is a question that confuses many people. In fact, patients with myocarditis should eat high-protein foods, high-vitamin foods, and those that are low in calories or easy to digest, such as a low-salt diet. It is recommended to eat small meals frequently and avoid foods that are spicy, heavily flavored, or irritating. For high-vitamin foods, the main choices include fruits, some vegetables, bean sprouts, kelp, seaweed, and black fungus, all of which are very good options. Low-calorie foods such as cucumbers, tomatoes, celery, job's tears, and papaya are also good choices. High-protein foods include soybeans, peanuts, seaweed, mushrooms, nuts, milk, lean meats, eggs, fish, shrimp, and more. We also recommend easily digestible foods, like millet porridge and noodles, as well as a low-salt diet, recommending a daily salt intake of no more than 3 grams for patients with myocarditis.

Criteria for Diagnosing Myocarditis

The diagnosis of myocarditis is primarily clinical, based on typical precursor symptoms, corresponding clinical manifestations, and physical signs. The precursor symptoms usually occur one to three weeks before the onset, including symptoms of a viral infection such as fever, general fatigue, and muscle soreness, or gastrointestinal symptoms like nausea and vomiting. Subsequently, symptoms such as chest tightness, palpitations, difficulty breathing, and even fainting and sudden death may occur. The physical signs generally include arrhythmias, commonly premature atrial contractions, premature ventricular contractions, or conduction blocks. There may be an increased heart rate which does not correspond to the body temperature, and there could be the presence of second or third heart sounds or gallop rhythm. A minority of patients may show signs of heart failure. Tests can include electrocardiograms, enzymatic studies, or echocardiograms, and magnetic resonance imaging may show symptoms of myocardial injury. To confirm the diagnosis, an endomyocardial biopsy must be performed.

How to relieve myocarditis pain?

If a patient is diagnosed with myocarditis, especially viral myocarditis, and experiences chest pain, some analgesic medications can be used, particularly non-steroidal anti-inflammatory drugs (NSAIDs). If the patient has infective endocarditis or other forms of myocarditis, it is not recommended to use pain-relieving medications due to individual differences, as this may exacerbate symptoms and mask the true condition. For general cases of myocarditis, it is sufficient to use some common NSAIDs. However, it is still important to actively treat the primary disease, control the patient's symptoms, and initially use antiviral medications predominantly, which can also alleviate symptoms. Regular echocardiogram reviews to monitor changes are also necessary.

Does myocarditis fear tiredness?

Myocarditis is an inflammatory disease of the myocardium. In treating it, reducing the cardiac load is crucial. For patients in the acute phase, rest is the best way to reduce cardiac load and is an important treatment measure for acute myocarditis. If a patient's heart condition, such as chest pain, elevated myocardial enzymes, or troponin, or severe arrhythmias, is present, we often recommend that the patient rest in bed for more than three months. Therefore, patients with myocarditis should avoid exertion and rest appropriately.
