Objective Inflammatory cardiomyopathy is characterised by inflammatory infiltrates leading to cardiac injury, left ventricular (LV) dilatation and reduced LV ejection fraction (LVEF). Several viral pathogens and autoimmune phenomena may cause cardiac inflammation. The effects of the gain of function FOXO3A single-nucleotide polymorphism (SNP) rs122...

Inflammatory cell infiltration is central to healing after acute myocardial infarction (AMI). The relation of regional inflammation to edema, infarct size (IS), microvascular obstruction (MVO), intramyocardial hemorrhage (IMH), and regional and global LV function is not clear. Here we noninvasively characterized regional inflammation and contractil...
Article
Background Mitochondrial dysfunction is a driving factor in the development of heart failure (HF) and relates to poor cardiac function. Through elevated oxidative stress it is linked to myocardial inflammation. Both mechanisms promote the development of cardiac fibrosis, a key contributor to adverse outcomes in ischaemic and non-ischaemic HF. Diffe...

SCN5A was considered an exclusively cardiac expressed ion channel but discovered to also act as a novel innate immune sensor. We report on a young SCN5A variant carrier with recurrent ventricular fibrillation and massive myocardial inflammation whose peculiar clinical course is highly suggestive of such a dual role of SCN5A. (Level of Difficulty: A...

Human parvovirus B19 (B19V) is the predominant virus currently detected in endomyocardial biopsies (EMBs). Recent findings indicate that, specifically, transcriptionally active B19V with detectable viral RNA is of prognostic relevance in inflammatory viral cardiomyopathy. We aimed to evaluate B19V replicative status (viral RNA) and beneficial effec...

Infection of the heart muscle with cardiotropic viruses is one of the major etiologies of myocarditis and acute and chronic inflammatory cardiomyopathy (DCMi). However, viral myocarditis and subsequent dilated cardiomyopathy (DCM) is still a challenging disease to diagnose and to treat and is therefore a significant public health issue globally. Ad...

Adenine nucleotide translocase 1 (ANT1) transfers ATP and ADP over the mitochondrial inner membrane and thus supplies the cell with energy. This study analyzed the role of ANT1 in the immune response of ischemic heart tissue. Ischemic ANT1 overexpressing hearts experienced a shift toward an anti-inflammatory immune response. The shift was character...

Background: Viral genesis is the most common cause of myocarditis. COVID-19-associated myocarditis seems to be a notable extrapulmonary manifestation, which may result in the need for a different treatment. There has been no positive polymerase chain reaction (PCR) testing of SARS-CoV-2 in heart specimens, thus far. Case summary: A 48-year-old mal...

Aims: Low cardiac iron levels promote heart failure in experimental models. While cardiac iron concentration (CI) is decreased in patients with advanced heart failure with reduced ejection fraction (HFrEF), CI has never been measured in non-advanced HFrEF. We measured CI in left ventricular (LV) endomyocardial biopsies (EMB) from patients with non...

Our results indicate a new mechanism by which ANT1 influences cardioprotection. Our study shows for the first time, that ANT1 is involved in cardio protective HSP27 signaling. ANT1-OE supports HSP27 expression and secretion from cardiomyocytes. Secreted HSP27 stimulates TLR4 thereby inducing AKT signaling, ANT as well as its own intracellular synth...

Cardiac amyloidosis is associated with very high morbidity and mortality. Only if treated early, cardiac amyloidosis responds well to therapy, and early recognition with a full differential diagnostic workup including multimodality imaging is therefore critical at first presentation. Closely meshed clinical monitoring and imaging are indispensable...

Background Myocarditis is an important cause of acute and chronic heart failure. Men with myocarditis have worse recovery and an increased need for transplantation compared with women, but the reason for the sex difference remains unclear. Elevated sera soluble (s)ST2 predicts mortality from acute and chronic heart failure, but has not been studied...
