Clinical manifestation and pathologic characteristic _ symptom of the viral myocarditis
The clinical manifestation of the viral myocarditis depends on extensive intensity and severity of pathological change, most cases are presented inferiorly and clinically type, can have no symptom at all. The heavy one can erupt serious arrhythmia, heart source shock in heart failure simultaneously, even die suddenly. And rotate to come back from l clinical symptom, course of disease and classify, viral myocarditis can be divided into several type the following:
1.Inferior clinical type myocarditis
The virus does not have subjective symptoms after being infected with, it is early that the routine inspection electrocardiogram has ST-T changing or rooms to discover, the room is early, several weeks later, these changes disappear or leave over the arrhythmia by oneself.
2.Since light disease and restricting myocarditis
L-3 can have uncomfortable can have ST-T change, shrink before various issues by palpitation, electrocardiogramming district in front of the slight heart week after virus infect, CK-MB and heart troponin T or I rise, but there is not cardiac dilatation, in heart failure to behave, resume gradually in a month through appropriate therapeutic l.
3.Hide progress type myocarditis
Virus have, pass myocarditis behave, find heart expand gradually after the several year infect, shown as the expanding myocardium disease.
4.Acute serious disease myocarditis
Symptoms such as chest aching, breathing hard, palpitation,etc. appear in 1- 2 weeks after the virus is infected, physical sign such as tachycardia, room galloping horse's law, cardiac dilatation in heart failure, even present source shock of heart. This kind of condition is critical, can die from the depleted or serious rhythm of the heart of the pump within several days not normally.
5.Dying suddenly myocarditis
There is no heart disease to behave before death, often die suddenly in the activity, it proved that there is acute viral myocarditis that the corpse is examined.
Pathology
The pathology of the viral myocarditis changes and lacks the specificity, myocarditis relying mainly on the fact that the cardiac muscle is damaged is shown as myocardium cell dissolving, necrosis, changing the sex and swelling,etc.; Can be divided into cooking stove and filling the air myocarditis of a office from the pathological change range.
