Fulminant myocarditis associated with influenza A virus is exceedingly rare, with only a few cases reported in the literature. We describe a previously healthy 10-year-old boy, with a three-day history of flu-like symptoms without antiviral treatment. He was hospitalized with dehydration and hypothermia in the context of persistent vomiting, when he suddenly developed heart failure secondary to...

Myocarditis Associated with 2009 Influenza A (H1N1) Pandemic in Japan organized by Japanese Circulation Society. A national survey on myocarditis associated with the 2009 influenza A (H1N1) pandemic in Japan. Circ J 2010; 74: 2193–9 3 Schultz JC, Hilliard AA, Cooper LT Jr, Rihal CS. Diagnosis and treatment of viral myocarditis. Mayo Clin Proc 2009; 84: 1001–9 4 Oda T, Yasunaga H, Tsutsumi Y, et...

Two cases of acute myocardial infarction occurred in association with myocarditis, which was confirmed by biopsy. The first patient suffered an anteroseptal and the second patient an inferior wall myocardial infarction shortly after an acute viral illness. In both patients, coronary angiography showed normal coronary arteries, and right ventricular endomyocardial biopsy confirmed myocarditis. H...

Kawasaki disease is an acute inflammatory disorder of medium-sized arteries that predominantly affects cardiac coronary arteries and children under the age of 5 years. Cardiac involvement usually happens later than 10 days after the onset of illness. Most of cardiac complications are coronary artery abnormalities (ectasia or aneurysms) and subclinical myocarditis. Clinical myocarditis (symptoma...

We describe the case of fulminant myocarditis due to Lyme disease and use of mechanical circulatory support (MCS) for the treatment of the Lyme carditis associated with refractory cardiogenic shock. Fulminant Lyme myocarditis in young adult male patient led to a sudden onset of acute, severe biventricular heart failure with progressive cardiogenic shock, and multiorgan failure immediately after...

Mercury is a widespread environmental contaminant with neurotoxic impacts that have been observed over a range of exposures. In addition, there is increasing evidence that inorganic mercury (iHg) and organic mercury (including methyl mercury) have a range of immunotoxic effects, including immune suppression and induction of autoimmunity. In this study, we investigated the effect of iHg on a mod...

Endomyocardial biopsies were performed in 11 African women in Nairobi who presented with the clinical features of peripartum cardiomyopathy. The samples were studied by light and electron microscopy. In five patients there was evidence of a "healing myocarditis", that is the presence of a mild inflammatory cell infiltration within the myocardium with foci of necrosis and variable amounts of hyp...

Heart disease, the leading cause of death in humans, is estimated to affect one in four American adults in some form. One predominant cause of heart failure in young adults is myocarditis, which can lead to the development of dilated cardiomyopathy, a major indication for heart transplantation. Environmental microbes, including viruses, bacteria, and fungi that are otherwise innocuous, have the...

BACKGROUND Elevated heart rate is associated with increased cardiovascular morbidity. The selective I(f) current inhibitor ivabradine reduces heart rate without affecting cardiac contractility, and has been shown to be cardioprotective in the failing heart. Ivabradine also exerts some of its beneficial effects by decreasing cardiac proinflammatory cytokines and inhibiting peroxidants and collag...

Fulminant myocarditis is a severe cardiac emergency that may lead to death if effective cardiopulmonary supports are not provided. This study aimed to evaluate the prognostic predictors in patients with fulminant myocarditis.We retrospectively analyzed the clinical characteristics, complications, laboratory findings, treatments, as well as electrocardiographic and echocardiographic data of 73 c...
