Patients with myocarditis generally have a self-limiting condition; it can heal completely without any treatment. However, sometimes, some myocarditis cases are fulminant, leading to acute heart failure or sudden death. For self-limiting diseases, since the condition is relatively mild, not receiving timely treatment can leave sequelae, such as some dilated cardiomyopathies, which are often due to the transformation from myocarditis. Therefore, for patients with myocarditis, we should follow up and conduct regular reviews to avoid the occurrence of dilated cardiomyopathy.

Is myocarditis cough severe?

Patients with myocarditis often exhibit early symptoms such as fever, cough, difficulty breathing, fatigue, and in severe cases, chest tightness and shortness of breath, even leading to shock or death, and syncope. Typically, the cough is not too severe, but if myocarditis is suspected, the patient should go to the hospital for timely diagnosis. Primary diagnostic tests include electrocardiogram, myocardial enzymes, and cardiac ultrasound. Once diagnosed, hospitalization for immediate treatment is necessary to prevent the condition from worsening. Because fulminant myocarditis can lead to death within days from minor symptoms, all myocarditis patients should be treated as severe cases and not be neglected.

What should be avoided in the diet for myocarditis?

Myocarditis is an inflammatory disease of the myocardium. Currently, there is no specific treatment for myocarditis. Patients should avoid fatigue, rest adequately to reduce cardiac load, and pay attention to nutritional intake. It is encouraged to eat easily digestible foods that are rich in vitamins and high in protein, and to avoid spicy, greasy, and hard-to-digest foods. Additionally, it is advisable to consume more fruits and vegetables, which are rich in vitamin C.

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.

What irritants should myocarditis avoid?

Suffering from myocarditis, fear of emotional stimulation. Myocarditis is caused by viral infection resulting in damage to the myocardium. Severe myocardial damage requires bed rest, maintaining a pleasant mood, and treatment with effective medication under the guidance of a doctor. Frequent anger or temper tantrums can cause increased sympathetic nervous excitability, leading to faster heart rates and increased cardiac burden. In severe cases, it can lead to acute heart failure, arrhythmias, cardiogenic shock, or even sudden death. Therefore, after being diagnosed with myocarditis, it is crucial to pay close attention to maintaining a cheerful mood and actively cooperating with the doctor for effective treatment.

What are the symptoms of myocarditis?

The clinical manifestations of myocarditis in patients depend on the extent and location of the lesion. Mild cases may have no symptoms at all, while severe cases can even present with heart failure and shock. Most patients have precursor symptoms of viral infection one to three weeks before the onset, such as fever, general fatigue, and muscle soreness. Some patients have gastrointestinal symptoms like nausea and vomiting. Subsequently, they may experience palpitations, chest pain, breathing difficulties, edema, and even fainting or sudden death. The majority of clinically diagnosed myocarditis cases primarily present with or are primarily symptomatic of psychological frailty. A minority of patients may experience fainting or Aschner's syndrome as a result.
