Overview: Viral myocarditis is one of the common heart diseases nowadays. Many viruses can cause myocarditis, the most common one being Coxsackie group B virus. It is generally believed that about 5% of viral infections can accumulate in the heart. Bacterial infections, malnutrition, strenuous exercise, pregnancy, and hypoxia can be triggers for the development of viral myocarditis, and most patients have fever, upper respiratory tract infection, diarrhea, and other precursor symptoms before the onset of the disease. Zhang Wenju, Department of Cardiovascular Medicine, Zhengzhou People’s Hospital Symptoms: The manifestation of viral myocarditis depends on the extensiveness of the lesion, which is highly variable and can be completely asymptomatic or lead to sudden death; common symptoms include palpitations, chest tightness, fever, malaise, shortness of breath, vague pain in the precordial region, myalgia, arthralgia, oliguria, and even syncope. Palpitations and chest tightness are the most common symptoms. Ancillary tests: blood white blood cell count is often slightly increased, red blood cell sedimentation rate is increased; cardiac enzymes are increased. Most of the electrocardiograms are accompanied by arrhythmias, and myocardial ischemic changes are less common. x-ray examinations have no abnormal findings in most cases, and may show signs of cardiac enlargement and pericardial effusion. Some ultrasound examinations may show limited ventricular wall motion or increased wall thickness. The performance of viral myocarditis varies from mild to severe, with no conscious symptoms, to severe sudden death, severe arrhythmia, cardiogenic shock or heart failure leading to death in the acute phase, to arrhythmia, myocardial pericarditis and myocardial infarction in between. Most patients who pass the acute phase recover completely within a few months after the disease, but a few continue to have enlarged heart and cardiac insufficiency after the acute phase, or have progressive development, leading to heart failure and even death. Prevention and treatment: 1, reduce the burden on the heart, pay attention to rest, strengthen nutrition 2, correct heart failure on behalf of: diuretics 3, control arrhythmia on behalf of: verapamil, betalactam, amiodarone, lidocaine, etc. 4, improve myocardial metabolism on behalf of: coenzyme A, coenzyme Q10, polarizing fluid, vitamin C, ginseng 5, antiviral and immunomodulatory drugs on behalf of: interferon, thymidine, transfer factor, astragalus
