Herein we present a case of fulminant myocarditis in a woman previously treated for B-cell lymphoma. While the clinical context was suggestive of adriamycin-induced cardiomyopathy, the initial pathology of the Heartmate-2 apical core showed lymphocytic myocarditis. After 8 months of stability, the patient presented with progressive heart failure and recurrent ventricular arrhythmias. An endomyo...

Abstract. – OBJECTIVE: Myocarditis, an acute inflammation disease of the heart, is a potentially lethal disease and can lead to sudden death. This study aims to investigate the therapeutic effect of lipoxin A4 (LXA4) on experimental autoimmune myocarditis (EAM) and to explore the underlying mechanism. MATERIALS AND METHODS: EAM was induced in BALB/c mice by injection of porcine cardiac myosin a...

Giant cell myocarditis, but not cardiac sarcoidosis, is known to cause fulminant myocarditis resulting in severe heart failure. However, giant cell myocarditis and cardiac sarcoidosis are pathologically similar, and attempts at pathological differentiation between the two remain difficult. We are presenting a case of fulminant myocarditis that has pathological features suggestive of cardiac sar...

Th1-type immune responses, mediated by IL-12-induced IFN-gamma, are believed to exacerbate certain autoimmune diseases. We recently found that signaling via IL-12Rbeta1 increases coxsackievirus B3 (CVB3)-induced myocarditis. In this study, we examined the role of IL-12 on the development of CVB3-induced myocarditis using mice deficient in IL-12p35 that lack IL-12p70. We found that IL-12 deficie...

OBJECTIVES Fulminant myocarditis with cardiogenic shock is fatal without mechanical circulatory support. Once haemodynamic stability has been established with a ventricular assist device (VAD), the decision to wait for myocardial recovery as opposed to listing for an orthotopic heart transplant (OHT) can be difficult. We have undertaken this study to establish the criteria for determining the n...

OBJECTIVE This study was to evaluate the levels of NT-proBNP in patients with myocarditis which occurred after a scorpion sting envenomation. MATERIAL AND METHODS A total of 30 patients with scorpion sting envenomation and 21 patients with heart failure which was caused by cardiomyopathy, were prospectively studied. The data included the patient demographics, clinical features, echocardiograp...

Myocarditis is simply defined as an inflammatory condition mainly located in the heart muscle, although considerable uncertainties still persist as to its etiologic, pathological, and clinical subclassifications. In addition to the possibility of an aspecific flulike prodrome, possible presentations include different degrees of heart failure (ranging from cardiogenic shock to subtly progressive...

Myocarditis is defined as inflammation of the heart muscle, and it frequently associates with impaired cardiac function. Although many kinds of viruses have been implicated as causes of myocarditis, these most commonly include enteroviruses, such as coxsackieviruses. Beside enteroviruses, adenovirus, hepatitis virus, parvovirus, and influenza virus have been reported to cause myocarditis. Of th...

Overexpression of the 18-kDa translocator protein (TSPO) is closely linked to inflammatory responses in the heart, including myocarditis, which can lead to myocardial necrosis. In vivo assessment of inflammatory responses has enabled the precise diagnosis of myocarditis to improve clinical outcomes. Here, we evaluated TSPO overexpression in a rat model of experimental autoimmune myocarditis (EA...

BACKGROUND Myocarditis is a disease caused by numerous etiological factors and characterized by a non-specific course. The only method allowing for precise characterization of inflammatory changes is the histopathological examination of heart muscle specimens. The study was conducted on heart muscle preparations from 11 dogs with ante-mortem diagnosis of cardiac disease. Animals presented with ...
