[Myocarditis of pseudo-infarctoid onset].
The authors report two cases of myocarditis in young individuals in whom clinical and electrocardiographic findings during the acute phase could have led to an erroneous diagnosis of myocardial infarction. The problem in such cases is that of a differential diagnosis with infarction with normal coronary arteries. Few clinical or paraclinical arguments are of diagnostic value, endomyocardial biopsy remaining the reference investigation. Proof of viral infection is not always obtained. It is often the retrospective argument of "complete return to normal" which supports the clinical impression. This usual benign outcome is not always the case, since cases of cardiogenic shock have been reported. The dual nature of the pathogenesis ("myositis" and/or "vasculitis" with thrombus and actual MI) is stressed.
