Expression and Potential Significance of miR-499 and IL-1 β in Serum of Dilated Cardiomyopathy Patients with Atrial Fibrillation
CONCLUSIONS: A close relationship exists between the abnormal expression of serum miR-499 and IL-1β and DCM complicated with AF, which will be of great importance in future research. In addition, the data of patients with DCM are related to the occurrence and development of AF, and clinicians should actively perform early drug interventions to reduce myocardial remodeling, so as to reduce the incidence of AF.PMID:38551417 (Source: Alternative Therapies in Health and Medicine)

Resveratrol Delays Diabetic Cardiomyopathy Fibrosis by Regulating Mitochondrial Autophagy
CONCLUSION: Resveratrol postpones dilated cardiomyopathy fibrosis by regulating the mitochondrial autophagy response through the AMP-activated protein kinase (AMPK)/silent mating type information regulation 2 homolog 1 (SIRT1)-mediated inositol-requiring enzyme 1 alpha (IRE1α)/PTEN-induced putative kinase 1 (PINK) signaling pathway.PMID:38551444 (Source: Alternative Therapies in Health and Medicine)

Ferroptosis in Cardiovascular Disease and Cardiomyopathies: Therapeutic Implications of Glutathione and Iron Chelating Agents
Biomedicines. 2024 Mar 1;12(3):558. doi: 10.3390/biomedicines12030558.ABSTRACTThis review explores ferroptosis, a form of regulated cell death reliant on iron-induced phospholipid peroxidation, in diverse physiological and pathological contexts, including neurodegenerative disorders, and ischemia-reperfusion. In the realm of cardiovascular diseases, it significantly contributes to cardiomyopathies, including dilated cardiomyopathy, hypertrophic cardiomyopathy, and restrictive cardiomyopathy. Ferroptosis involves intricate interactions within cellular iron metabolism, lipid peroxidation, and the balance between polyunsatura...

LncRNA H19: A Novel Biomarker in Cardiovascular Disease
Acta Cardiol Sin. 2024 Mar;40(2):172-181. doi: 10.6515/ACS.202403_40(2).20230925A.ABSTRACTCardiovascular disease is a major cause of death and disability worldwide. Recently, increasing evidence has demonstrated that long non-coding RNAs (lncRNAs) play critical roles in the pathogenesis of cardiovascular diseases, including atherosclerosis, coronary artery disease, dilated cardiomyopathy, diabetic cardiomyopathy, aortic dissection, and more. LncRNA H19 was the first to be described as a non-protein-coding mRNA-like molecule. A large number of studies have found that lncRNA H19 is related to the pathophysiological processes...

Temporal progression of replacement and interstitial fibrosis in optimally managed dilated cardiomyopathy patients: A prospective study
Background: To prospectively examine the dynamic evolution of fibrotic processes within a one-year in patients with dilated cardiomyopathy (DCM). Methods: Between May 2019 and September 2020, 102 DCM patients (mean age 45.2  ± 11.8 years, EF 29.9 ± 11.6%) underwent cardiac magnetic resonance (CMR-1). After 13.9 ± 2.9 months, 92 of these patients underwent a follow-up CMR (CMR-2). Replacement fibrosis was assessed via late gadolinium enhancement (LGE), quantified in terms of LGE mass and extent. Inter stitial fibrosis was evaluated via T1-mapping and expressed as extracellular volume fraction (ECV). (Sour...

Left ventricular assist device temporary explantation as a strategy for infection control in a pediatric patient
We report a case of temporary Berlin Heart EXCOR ® explantation in a pediatric patient with idiopathic dilated cardiomyopathy who suffered an uncontrollable inflow cannulation site infection while on bridge-to-transplantation. Despite failure to thrive and catheter-related infections, once free of the device, the patient was cured of infection us ing systemic antibiotics and surgical debridement. The patient underwent EXCOR® reimplantation after four months, and is awaiting heart transplantation in stable condition. A life-threatening ventricular assist device-related infection may require device explantation under condi...

GSE262123 Mechanisms Underlying Dilated Cardiomyopathy Associated with FKBP12 Deficiency
Contributors : Md Abul Hassan Samee ; Kevin S Ho ; Susan L HamiltonSeries Type : Expression profiling by high throughput sequencingOrganism :To define the role of the immunophilin FKBP12 in cardiac function, two conditional models of FKBP12 deficiency were created using Fkbp1a floxed (FL) mice expressing Cre+ recombinase under the control of different promoters ( α-myosin heavy chain, αMHC, and muscle creatine kinase, MCK) that differ in both developmental stage of expression (E9 versus E 13) and Cre+ expression levels. In adult mice FKBP12 was reduced by 96% and 86% in αMHC-Cre+- and MCK-Cre+-FKBP12 deficient mice, r...

Neuromuscular and cardiovascular phenotypes in paediatric titinopathies: a multisite retrospective study
Conclusion Our cohort demonstrates the genotype–phenotype spectrum of paediatric-onset titinopathies identified in clinical practice and highlights the risk of life-threatening cardiovascular complications. We show the difficulties of obtaining a molecular diagnosis, particularly in neuromuscular patients, and bring awareness to the complexities of genetic counselling in this population.

Biallelic PKP2 loss of function variants are associated with a lethal perinatal-onset biventricular dilated cardiomyopathy with excessive trabeculations and ventricular septal defects
We report three more cases from two families with homozygous pathogenic PKP2 variants and perinatal-onset, lethal DCM-ET. Identification of the genetic abnormalities played a key role in decision-making and family counselling in these cases. This case series supports the published evidence that biallelic loss of function PKP2 variants cause a lethal, perinatal-onset cardiomyopathy. (Source: Journal of Medical Genetics)

Novel SCN5A gene mutation in a patient affected by multifocal ectopic premature Purkinje ‐related contractions syndrome
We report the case of a 36-year-old woman who presented to the emergency department complaining of palpitations and asthenia. Investigations showed frequent ventricular ectopy and severe left ventricular ejection fraction impairment. She was diagnosed with a peculiar condition defined multifocal ectopic premature Purkinje-related contractions syndrome, which in some cases can be associated with a dilated cardiomyopathy phenotype. Genetic testing showed a novel mutation in the SCN5A gene (c.673C  >  G). In the context of acute left ventricular dysfunction in a young patient, we discuss the clinical presentation of this...

Clinical characteristics, treatment, trajectories and outcome of patients with dilated cardiomyopathy in a national heart failure registry
Available data on the clinical characteristics and prognosis of patients with heart failure (HF) due to dilated cardiomyopathy (DCM) derive mainly from tertiary care centres for cardiomyopathies or from drug trial sub-studies, which may entail a referral bias.

BAG3 localizes to mitochondria in cardiac fibroblasts and regulates mitophagy
Am J Physiol Heart Circ Physiol. 2024 Mar 15. doi: 10.1152/ajpheart.00736.2023. Online ahead of print.ABSTRACTThe co-chaperone BAG3 is a central node in protein quality control in the heart. In humans and animal models, decreased BAG3 expression is associated with cardiac dysfunction and dilated cardiomyopathy. While previous studies focused on BAG3 in cardiomyocytes, cardiac fibroblasts are also critical drivers of pathologic remodeling. Yet, BAG3's role in cardiac fibroblasts is almost completely unexplored. Here, we show BAG3 is expressed in primary rat neonatal cardiac fibroblasts and preferentially localizes to mitoch...
