Abstract

Telling story of myocarditis is characterized by discoveries and inventions. The invention of the microscope opened new avenues in medicine, with the observation of myocardial inflammation by Carl Ludwig Alfred Fiedler. Rudolph Virchow discovered that cells are the elementary units. Karl Albert Ludwig Aschoff first reported rheumatic pancarditis. Gilbert Dallford found enterovirus in the faeces of children, who died suddenly in the village of Coxsackie. Werner Forssmann entered in his own right ventricle with a urologic catheter via the left radial vein. Endomyocardial biopsy, via the femoral or jugular veins, made possible to take away myocardial samples in vivo, for diagnosis of myocarditis or cardiac rejection of transplanted heart. The invention of polymerase chain reaction by Kary Mullis allowed to achieve diagnosis of concealed infections and genetically determined cardiomyopathies. Myocarditis, a significant cause of sudden death, was found to be frequently ascribed to viruses. Cytotoxicity of Coxsackievirus B was proved to consist on released protease 2, encoded by virus genome and cleaving dystrophin. RNA (Coxsackie) and DNA (adenovirus) viruses share a common receptor. Cardiac magnetic resonance revealed to be sensitive and specific in the diagnosis of myocarditis by detecting myocardial oedema. However, it is unable to establish the histotype. The onset of myocarditis may be fulminant; however, extracorporeal membrane oxygenation, invented by Robert Bartlett, allows heart rest, while replacing cardiac contractility. High rates of survival have been achieved, probably because of mild myocardial damage.

期刊介绍: The European Heart Journal Supplements (EHJs) is a long standing member of the ESC Journal Family that serves as a publication medium for supplemental issues of the flagship European Heart Journal. Traditionally EHJs published a broad range of articles from symposia to special issues on specific topics of interest. The Editor-in-Chief, Professor Roberto Ferrari, together with his team of eminent Associate Editors: Professor Francisco Fernández-Avilés, Professors Jeroen Bax, Michael Böhm, Frank Ruschitzka, and Thomas Lüscher from the European Heart Journal, has implemented a change of focus for the journal. This entirely refreshed version of the European Heart Journal Supplements now bears the subtitle the Heart of the Matter to give recognition to the focus the journal now has. The EHJs – the Heart of the Matter intends to offer a dedicated, scientific space for the ESC, Institutions, National and Affiliate Societies, Associations, Working Groups and Councils to disseminate their important successes globally.
