Definition
Discovered in 1920, also called Fiedler's interstitial myocarditis, this myocarditis, the origin of which is not precisely known, is probably allergic.
Generalities
This type of myocarditis is characterized by the penetration into the myocardium of a variety of white blood cells, lymphoplasmocytes, or sometimes by another variety of white blood cells, granular leukocytes.
It is also accompanied by a multiplication of connective cells (a variety of tissues containing proteins and entering into the composition of the majority of the body's tissues).
Fiedler myocarditis occurs primarily in young adults and results in rapidly onset and fatal cardiac failure.
Symptoms
Pathophysiology
The term myocarditis is commonly used to refer to inflammation of the myocardium (heart muscle) most often due to an infectious disease.
Inflammation of muscle fibers is accompanied by inflammation of the interstitial tissue (tissue supporting the muscle fibers) with alteration of the myofibrils (muscle fibers) and in some individuals this inflammation is associated with the appearance of fibrous tissue (having lost its natural elasticity).
