What is viral myocarditis?

Myocarditis is an acute, subacute, or chronic inflammatory lesion that reflects a localized or diffuse presence in the myocardium, and the diagnosis of viral myocarditis must be based on evidence of myocarditis and evidence of viral infection.

Various viruses can cause viral myocarditis, the most common is caused by coxsackievirus, echovirus, poliovirus, influenza virus, parainfluenza virus, respiratory syncytial virus, adenovirus can sometimes be caused, in addition, measles, mumps, Japanese encephalitis, hepatitis, cytomegalovirus.

There are no special precautions, usually pay more attention to exercise, increase resistance, and eat a balanced and nutritious diet.

Most recover with proper ** and leave no signs or symptoms behind. Rarely, in the acute phase of the disease, death due to severe heart failure, arrhythmias, and cardiogenic shock occurs. Some of them will produce varying degrees of heart enlargement, arrhythmia, and abnormal changes in the electrocardiogram, which are sequelae caused by the formation of myocardial scarring.

Some patients develop chronic myocarditis and die from these complications for years or even decades.

Try to make it as simple and easy to understand, and the places where you really use professional terms are nouns, and you can't replace the explanation).

1.Viral myocarditis is an inflammatory lesion of the heart muscle caused by a viral infection.

2.In the acute stage, patients should rest sufficiently, and those with mild symptoms generally need to rest for at least 3 months after the fever subsides, heart rate, heart size and function return to normal: severe patients should rest for half a year to 1 year.

And we should pay attention to nutrition, especially eat foods rich in vitamin C, a large amount of vitamin C can improve the body's ability to resist disease, improve myocardial metabolism and help repair damaged myocardium.

3.Most of the disease is mild, the prognosis is good, and a small amount of premature beats is not a major health hazard, nor does it affect normal work and life. Premature beats may increase due to certain factors, such as smoking, alcoholism, coffee, strong tea, fatigue, nervousness, and upset.

Disease name: Myocarditis is an inflammatory reaction of cardiomyocytes, endocardium, blood vessels, and pericardial visceral layers triggered by various infectious factors.

Department: Department of Cardiovascular Medicine.

Epidemiology: There is no exact data on the incidence of viral myocarditis, it is generally estimated that the annual incidence of viral myocarditis in children is less than 1.1 million, and it can occur in all ages from infants to the elderly, from the perspective of clinical onset, children and adults under 40 years old, 35% of patients are 10 30 years old, there is no obvious gender difference in the incidence of myocarditis, and it is generally believed that males are slightly higher than females.

**: Viral myocarditis is caused by a variety of viral infections.

Symptoms: The clinical manifestations of patients with viral myocarditis depend on the extent and location of the lesions, ranging from complete asymptomatic cases to sudden death from shock.

Typical symptoms. Patients usually present with symptoms of viral infection, with a prodrome of viral infection 1 to 3 weeks prior to the onset of illness, usually gastrointestinal and respiratory tract infections, manifested by fever, malaise, and muscle aches; Gastrointestinal symptoms such as nausea, vomiting, diarrhea, etc.

Subsequently, heart-related clinical symptoms appeared, including chest tightness, pressure in the anterior chest area, chest pain, palpitations, etc., and when the condition was severe, the patient felt severe palpitation, and felt that the heart was stopped and the heartbeat was irregular.

Accompanying symptoms. Viral myocarditis causes a decrease in heart function, which can cause symptoms of insufficient blood supply to the whole body, such as fatigue, exhaustion, indigestion, dizziness, and difficulty breathing.

Endocardial myocardial biopsy, which is considered the gold standard for diagnosis. In addition to being used to confirm the diagnosis of the disease, it is also helpful in the judgment of disease and prognosis. Because this test is an invasive beard ruler test, it is mainly used for patients with acute illness, poor response, and unknown causes.

For patients with mild disease, testing is generally not routine.

Health tips: There is no need to panic when patients with new coronavirus infection have palpitations and palpitations, viral myocarditis can be prevented and treated, and early diagnosis and symptomatic treatment can help block the development process of viral myocarditis.

Viral myocarditis is a serious heart disease with a lot of symptoms, and a friend of mine had this disease last year, and I saw the symptoms of him at that time, and I felt very painful.

1.Symptom. 1. The clinical manifestations of patients with viral myocarditis depend on the extent and location of the lesions, ranging from asymptomatic to heart failure, cardiogenic shock and sudden death.

2.Symptom. 2. Patients often have a history of upper respiratory tract or intestinal infection 1 to 3 weeks before the onset of the disease, which is manifested by fever, body aches, sore throat, fatigue, nausea, vomiting, diarrhea and other symptoms.

3.Symptom. 3. When the patient develops the disease, there will be palpitations, chest tightness, chest pain or vague pain in the precordial area, and there will be dizziness, unsteady standing, difficulty breathing, and some patients will also have general edema.

Precautions. Patients with viral myocarditis should pay attention to their usual diet, in which I eat foods that regulate qi and blood, and foods that are rich in nutrients, low fat and high protein.

First of all, viral myocarditis refers to the acute or chronic inflammatory lesions of myocardium caused by viral infection or diffuse, which is an infectious myocardial disease, about 5% of patients develop myocarditis during the viral epidemic infection, and it can also be scattered in the onset of the disease, and the clinical manifestations are different from the severity, according to the typical corresponding clinical manifestations of the previous infection, electrocardiogram, myocardial injury markers, echocardiogram**, showing evidence of myocardial injury should be considered for diagnosis, diagnosis depends on endocardial myocardial biopsy, and there is currently no specific ** Methods** are mainly for viral infection and myocardial inflammation, most patients can be cured after appropriate **, a very small number of patients die due to severe arrhythmias, acute heart failure or cardiogenic shock during the acute period, and some patients may also transform into dilated myocardial disease. Viral myocarditis refers to the direct action of viruses on the heart, including acute viruses, and persistent viral damage to the heart muscle. Cellular immunity is mainly mediated by T cells, a variety of cytokines and carbon monoxide to myocardial damage and microvascular damage.

The general clinical manifestations of viral myocarditis are pre-symptoms of viral infection such as fever, malaise, so-called flu-like symptoms, and gastrointestinal symptoms such as nausea and vomiting in the first 1 to 3 weeks before the onset of the disease. Then palpitations, chest pain, dyspnea, etc., generally ECG, ST-T changes and various types of arrhythmias, myocardial enzyme tests, serum troponin I or T, myocardial creatine kinase, isoenzyme elevation, increased erythrocyte sedimentation rate, increased C-reactive protein, etc. are helpful for diagnosis.

Viral acute viral myocarditis, usually pre-presented.

A history of colds for one or two weeks, especially coxsackievirus infection, without good rest, the virus affects the myocardium, causing necrosis of myocardial cells, causing acute viral myocarditis. **Must be active, to absolute bed rest, if you are at work or class, you need to ask for leave or leave of absence to rest at home, and then nourish the myocardium**, the acute phase can be antiviral**.

Acute viral myocarditis is classified as mild, moderate, and severe. In mild cases, rest is usually relieved. If it is severe or severe, it is important to go to the hospital for active **, because it may cause sudden cardiac death.

If it is not complete, some myocarditis will turn into dilated cardiomyopathy, the heart will get bigger and bigger, and then heart failure will appear, so the ** of viral myocarditis should be very positive.
