ConclusionWe found no associations between markers of immunothrombosis and new-onset AF in the general population. Inflammation and immunothrombosis may be associated with AF through other cardiovascular risk factors or predisposing conditions of AF. Our findings challenge the added value of biomarkers in AF risk prediction.Graphic abstract

Nurses in all settings should know the basics, as medications and physiological changes can cause cardiac arrhythmias. Each article will start with a brief case scenario and an ECG strip and then take you step by step through analyzing the heart rhythm.PMID:34554992 | DOI:10.1097/01.NAJ.0000794284.89236.a3

AbstractPurpose of ReviewThere is emerging evidence for important sex differences in cardiac arrhythmias. In this up-to-date review, we summarise the differences in incidence, aetiology, treatment and prevention of ventricular arrhythmias (VAs) and sudden cardiac death (SCD) in women versus men, in the context of ischaemic and nonischaemic cardiomyopathies.Recent FindingsThe incidence of ventricular tachyarrhythmia and SCD is significantly lower in women than in men with ischaemic cardiomyopathy, whereas sex differences in nonischaemic cardiomyopathy are less clear. Women who receive a primary prevention implantable cardio...

In this study, we show that performing a prior dimensionality reduction on FOM snapshots through randomized proper orthogonal decomposition (POD) enables to speed up training times and to decrease networks complexity. Accuracy and efficiency of this strategy, which we refer to as POD-DL-ROM, are assessed in the context of cardiac EP on an idealized left atrium (LA) geometry and considering snapshots arising from a NURBS (non-uniform rational B-splines)-based isogeometric analysis (IGA) discretization. Once the ROMs have been trained, POD-DL-ROMs can efficiently solve both physiological and pathological cardiac EP problems,...

During cardiac arrhythmias, dynamical patterns of electrical activation form and evolve, which are of interest to understand and cure heart rhythm disorders. The analysis of these patterns is commonly performed by calculating the local activation phase and searching for phase singularities (PSs), i.e., points around which all phases are present. Here we propose an alternative framework, which focuses on phase defect lines (PDLs) and surfaces (PDSs) as more general mechanisms, which include PSs as a specific case. The proposed framework enables two conceptual unifications: between the local activation time and phase descrip...

Can J Physiol Pharmacol. 2021 Sep 21. doi: 10.1139/cjpp-2021-0093. Online ahead of print.ABSTRACTCoronavirus disease 2019 (COVID-19), an acute and highly transmissible infectious disease has reached a pandemic level since March 11, 2020 and continues to challenge the healthcare system worldwide. The pathogenesis of COVID-19 is a complex process involving mechanisms that suppress the host antiviral and innate immune response, while triggering marked activation of coagulation and hyperinflammation leading to cytokine storm in severe COVID-19. This review summarizes current evidence related to COVID-19-associated cardiovascul...

CONCLUSIONS: This is the first article evaluating Pd and Tp-e parameters of children with DKA. In this study, cardiac arrhythmia risk markers were detected to be increased in children with DKA. Therefore, clinicians should be careful about the possibility of development of new arrhythmias during DKA treatment.PMID:34538047 | DOI:10.4274/jcrpe.galenos.2021.2021.0165

ConclusionConsidering the available data in the literature, it needs to be assumed that CD4+CD28null T lymphocytes are mainly involved in the development of AF and disease progression. Of utmost importance, it can be considered as the result of a T-cell-mediated auto-immune reaction among myocardial tissue. However, mechanisms which recruit CD4+CD28null cells in cardiac tissue remain unclear and need further investigation.

In this study, we aimed to investigate the relationship between EFT thickness and the development of new-onset AF in patients with NSTEMI during in-hospital follow-up.METHODS: We enrolled 493 consecutive patients who were diagnosed NSTEMI in this study. During in-hospital follow-up, 68 patients developed AF, and the remaining 425 patients were determined as the control group. The thrombolysis in myocardial infarction (TIMI) risk score for NSTEMI was calculated. All clinical, echocardiographic, and laboratory parameters were compared between the 2 groups.RESULTS: EFT thickness was higher in the AF group than in the controls (p
