Sources: Disturbances Of The Heart
It should be understood that especially in acute conditions a
positive separation of endocarditis from myocarditis is incorrect.
Acute endocarditis can probably not occur without some inyocarditis,
and myocarditis probably does not occur without some endocardial
disturbance and perhaps some pericardial irritation. This is
especially true in endocarditis which occurs during any acute
infection, even in rheumatism. The greater the amount of
pericarditis, the more serious is the acute condition. The greater
the amount of myocarditis, the more doubtful is the heart strength
in the near future. The greater the amount of endocarditis, the
greater the doubt of freedom from future permanent valvular lesions.
Endocarditis may be divided into: acute mild (simple) endocarditis,
acute malignant (ulcerative, infective) endocarditis, chronic
endocarditis and valvular disease.
