Science of myocardium and myocarditis

　　Cardiomyopathy is a group of heterogeneous cardiomyopathy caused by various causes of myocardial dysfunction, the most common type is hypertrophic cardiomyopathy, the main lesions in cardiomyocytes.

　　Myocarditis is a localized or diffuse inflammatory lesion of the myocardium caused by various causes. Inflammation not only accumulates cardiomyocytes, but also includes stroma, blood vessels, pericardium and endocardium, which is more extensive than cardiomyopathy.

　　Cardiomyopathy (here take the common hypertrophic cardiomyopathy as an example) and myocarditis are diseases of the heart, both of which are manifested as dull pain in anterior cardiac region, weakness of limbs, palpitations, chest tightness, dizziness, headache and other manifestations of heart disease.

　　Genetically, cardiomyopathy tends to run in families, with about 50% of patients having chromosomal abnormalities.

　　By age. Cardiomyopathy often occurs in young adults aged 30 to 40 years, which is the main cause of sudden death of young people and athletes. There is no clear age range for myocarditis. There are also patients with cardiomyopathy who come on gradually. Starting from the prime of life, with the growth of age, the symptoms of myocardial ischemia and arrhythmia gradually worsen, and no other clear diseases lead to hypertrophic cardiomyopathy. Belongs to infectious disease and myocarditis, most patients have a clear incentive before have to myocarditis, is one of the most common viral infection, there are many kinds of, can cause myocarditis virus, coxsackie virus, for example, can be virus, influenza virus, hepatitis virus, adenovirus, polio, measles, rubella virus, the mumps virus, epidemic hemorrhagic fever virus and so on, this means a lot of people are in with influenza, hepatitis, mumps, polio and other diseases before he was diagnosed with myocarditis.
