Viral myocarditis viral myocarditis_ general knowledge
Summary
Viral myocarditis (viral myocarditis) It mean infect, cause disposition it have a liking for virus, by cardiac muscle and among inflammations specifics non- is for myocarditis of pathological changes main quality. Have limitation or acute, subnormal temperature or chronic inflammation nature pathological change of person who fill the air in the cardiac muscle. Although pathological change takes cardiac muscle as the core, the membrane can also be given much trouble in the pericardium, heart. This disease can be seen in an age group, children are higher. Viral myocarditis is one of the reasons why children and teenagers die suddenly.
Cause of disease various virus can cause myocarditis, SaQi, angstrom but (ECHO) Ke among the intestinal virus , the poliomyelitis and virus, in order to cause the main virus of myocarditis; Glue virus such as influenza, pack influenza, respiratory tract shut afterbirth myocarditis that virus,etc. cause rare; The adenovirus causes myocarditis occasionally too. In addition, measles, parotitis, encephalitis B, hepatitis, big and small afterbirth virus,etc. can also cause myocarditis. The intersection of overwhelming majority and viral myocarditis can virus cause by Ke Sa strange virus and angstrom on the clinic. Group B of the strange virus of Ke Sa is the first pathogen of the human myocarditis, account for 30%-50%, see at most by 2, 4 two groups according to it one type, 5, 3, 1 type takes second place; Various group A 1, 4, 9, 16, 23s are apt to infringe babies, invade adult's cardiac muscle once in a while.
Mechanism 1 of the onset, virus act on the acute or lasting virus and produce and dissolve the cell material behind infecting myocardium cells directly, make cells dissolve.
2,The cell immunity is mainly T cells, and many kinds of cell factor and nitrous oxides,etc. lie between the cardiac muscle led to damage and damage with the blood capillary, these changes can damage heart function and structure.
Quality pathological change while having substantive pathological change relying mainly on myocardium pathological change and relying mainly on a quality that pathology changes viral myocarditis. There are filling the air cooking stoves of drawn game according to the pathological change range. Different with the weight of condition, it is different too that pathology changes the intensity. Under microscope, among the myocardium fiber and can find cell soak in the connective tissueing around the blood vessel, take monocyte as the core. Myocardium cells can be changing the sex, dissolve or necrosis. Pathological change if the district can amalgamate pericarditis, become viral pericardium myocarditis under the pericardium. Can last cardiac muscle pathological change and among quality,it is get up to the rooms form, prop up room room bunch and bunch at room forming, room after fighting and conducting system such as sinus that heart not to can also involve, become the morbidity foundation of arrhythmia. The stronger the virulence of the virus is, the wider the pathological change range is.
Clinical manifestation
1,The medical history has illness coming on age is seen more with children and teenagers. Have the upper respiratory tract or digestive tract virus to infect the history in 1-3 weeks before the onset.
