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 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.

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 is myocarditis treated?

Let's talk about how myocarditis is treated. Myocarditis is actually considered a self-limiting disease with no specific cure. However, treatment generally revolves around symptomatic treatment, combining conventional care and symptom management. For general treatment, bed rest is highly recommended for patients suffering from acute viral myocarditis to reduce the strain on the heart. Patients suffering from severe arrhythmias or heart failure are advised to rest in bed for at least one month and are not allowed to participate in strenuous physical labor for six months. For those without cardiac morphological or functional changes, rest for half a month is recommended, followed by avoiding heavy physical activity for three months. Additional antiviral treatments, such as interferon-alpha and Astragalus membranaceus, may be used; protective cardiac therapies or immunotherapies may also be administered. Symptomatic treatment mainly targets patients with severe heart failure or severe arrhythmias, following conventional treatment protocols for these conditions. For patients with complete atrioventricular block, temporary pacemakers may be used, and permanent pacemakers can be installed depending on the situation if the block cannot be resolved. Depending on the type of arrhythmia, antiarrhythmic medications like beta-blockers, amiodarone, and others may also be used. As each patient's cause of illness, severity, and physical constitution vary, it is essential to undergo personalized treatment under the guidance of a doctor.

Early manifestations of myocarditis

What are the early symptoms of myocarditis? In fact, most patients with myocarditis typically exhibit acute onset of symptoms, which generally occur 1 to 3 weeks after cardiac involvement, or they may simultaneously exhibit various degrees of viral infection symptoms such as fever, sore throat, cough, general malaise, muscle pain, skin rash, or nausea and vomiting, abdominal pain, and diarrhea. These are its prodromal symptoms. Additionally, some patients exhibit systemic viral infection symptoms when the disease occurs, such as rubella, measles, epidemic mumps, viral hepatitis, and other diseases. Since the recovery rate of myocarditis in the acute and recovery phases is significantly higher than in the lingering or chronic phases, it is evident that treatment for myocarditis should be initiated as early as possible to increase the recovery rate.

Do children with myocarditis have a fever?

In general, viral myocarditis is the most common form of myocarditis in children. This condition can be caused by various viruses such as influenza, parainfluenza, Coxsackie virus, adenovirus, etc., affecting the pediatric cardiac muscle tissue, which in turn can lead to symptoms of myocarditis. Since it is an infectious disease, fever is a common symptom. Fevers associated with myocarditis might present as high or moderate. Treatment primarily focuses on cardiac recovery, nourishing the cardiac muscle, steroids, and immunoglobulins, among others. Severe myocarditis is a critical condition that requires timely diagnosis and treatment to avoid worsening the situation.
