Viral myocarditis
What is Viral myocarditis Introduction?
Myocarditis is the limitation or diffuse myocardial inflammation, may be primary cardiomyopathy, but also a part of systemic diseases. Cause of infection, physical and chemical factors, and drugs, the most common is viral myocarditis, especially enteroviruses, especially Coxsackie B virus infection up to see.
What is Cause of viral myocarditis?
Viral myocarditis is caused by a variety of virus infection, of which the most common Coxsackie virus B, varicella, EB can also be caused by viruses. After infection overworked, engaged in heavy manual labor and strenuous exercise, high incidence of viral myocarditis. In addition, malnutrition is also an incentive. 5% of HIV infections may be involved after the occurrence of myocarditis in the heart of the heart. After infection for a direct invasion of cardiac, but also for virus-induced autoimmune response. Children found the former to the latter more common in young people. And the spring of viral myocarditis is high season.
What are the Symptoms of viral myocarditis?
Viral myocarditis have varying severity, so the symptoms varies widely. Mild, the limitations of lesion can be no symptoms, no ECG abnormalities, erythrocyte sedimentation rate, no increase in enzyme. Some people because of an accident until an autopsy had found that myocarditis lesions. In serious cases the symptoms are obvious, diffuse expansion of heart, heart failure, resulting in significant dyspnea, can not be lying; some serious heart disorders, which occur repeatedly syncope and even sudden death.
Viral myocarditis symptoms: fatigue, fever, chest tightness, palpitations, shortness of breath, dizziness, severe cases, heart failure can occur or cardiogenic shock. Viral myocarditis signs: heart rate increased rapidly, with a disproportionate increase in body temperature, heart-border expansion of the noise changes, arrhythmia.
How is diagnosis of viral myocarditis?
The diagnosis of viral myocarditis must establish evidence of myocarditis and virus infection. Chest tightness, heart palpitations often prompts affected, the heart of the expansion of cardiac arrhythmia or heart failure significantly impaired the performance of the ECG ST-T changes and ectopic cardiac rhythm or conduction disturbances reflect the existence of myocardial disease. Other tests include X-ray examination, blood test, virology screening.
How is Treatment of viral myocarditis?
1. the primary disease treatment: is critical. HIV antiviral drugs can be, amantadine daily 200mg; Ma phenanthroline guanidine 0.1g, orally, 3 times a day, with bacterial infection, antibiotics may be.
2. symptomatic treatment: the acute phase should be bed rest, the symptoms and signs improved, ECG can be gradually increased to normal activities, to the nutrient-rich, easy to digest diet. Emergence of heart failure, arrhythmia, shock should be actively corrected.
3. the promotion of myocardial metabolism:
How is Prevention of viral myocarditis
Prevention of viral myocarditis should prevent colds, intestinal viral infections, often in physical exercise to improve the physical disease and often living room window ventilation to keep the air fresh. Occurred in the cold season, to as little as possible to place more crowded, pay attention to prevent infection. Once the virus was found necessary to pay attention to rest and avoid fatigue.
