Patient vulnerability in stereotactic arrhythmia radioablation (STAR): a preliminary ethical appraisal from the STOPSTORM.eu consortium
AbstractThis preliminary ethical appraisal from the STOPSTORM.eu consortium is meant to raise critical points that clinicians administering stereotactic arrhythmia radioablation should consider to meet the highest standards in medical ethics and thus promote quality of life of patients recruited for radiotherapy treatments at a stage in which they experience a significant degree of vulnerability.

Classification Method of ECG Signals Based on RANet
AbstractBackgroundElectrocardiograms (ECG) are an important source of information on human heart health and are
widely used to detect different types of arrhythmias.ObjectiveWith the advancement of deep learning, end-to-end ECG classification models based on neural
networks have been developed. However, deeper network layers lead to gradient vanishing. Moreover, different
channels and periods of an ECG signal hold varying significance for identifying different types of ECG
abnormalities.MethodsTo solve these two problems, an ECG classification method based on a residual attention neural network
is proposed i...

Atrial fibrillation de novo in acute coronary syndrome
Arch Cardiol Mex. 2024;94(2):181-190. doi: 10.24875/ACM.23000008.ABSTRACTOne of the complications during an acute coronary syndrome event is the presence of arrhythmias. Among them, those of the supraventricular type, especially atrial fibrillation, carry a poor prognosis both in the short and long term, being the cause of situations such as cerebrovascular event, ventricular arrhythmias, and increased mortality. The arrhythmia tends to appear in a certain population group with particular risk factors during the index event in approximately 10% of cases. Appropriate treatment at the time of its onset, thanks to the use of ...

Editorial to “Association of Left Atrial Appendage Morphology and Function with Stroke and Transient Ischemic Attack in Atrial Fibrillation Patients”
Atrial fibrillation (AF) is the most commonly encountered arrhythmia in clinical practice and is an independent risk factor for strokes. A thromboembolic event risk assessment based on the CHA2DS2-VASc score is recommended by the guidelines. However, strokes also occur even in some populations with low CHA2DS2-VASc scores. Thus, new factors to improve the risk stratification of thromboembolic events are needed. A major embolic source associated with AF is the left atrial appendage (LAA). Previous reports showed that the LAA endocardium has more enhanced expression of a prothrombotic profile and proinflammatory proteins tha...

Discovery and Structure-Activity Relationship of a Ryanodine Receptor 2 Inhibitor
Chem Pharm Bull (Tokyo). 2024;72(4):399-407. doi: 10.1248/cpb.c24-00114.ABSTRACTRyanodine receptor 2 (RyR2) is a large Ca2+-release channel in the sarcoplasmic reticulum (SR) of cardiac muscle cells. It serves to release Ca2+ from the SR into the cytosol to initiate muscle contraction. RyR2 overactivation is associated with arrhythmogenic cardiac disease, but few specific inhibitors have been reported so far. Here, we identified an RyR2-selective inhibitor 1 from the chemical compound library and synthesized it from glycolic acid. Synthesis of various derivatives to investigate the structure-activity relationship of each s...

Analyses of lncRNA and mRNA profiles in recurrent atrial fibrillation after catheter ablation
ConclusionsThe recurrence of atrial fibrillation after catheter ablation may be associated with immune responses and fibrosis, with the extracellular matrix playing a crucial role. TMEM51-AS1-201 has been identified as a potential key target for AF recurrence after catheter ablation. (Source: European Journal of Medical Research)

Elucidating effects of the environmental pollutant benzo[a]pyrene [BaP] on cardiac arrhythmogenicity
Environmental pollution causes cardiovascular disease, heart failure, and arrythmias [1 –4]. Wildfire emissions are a complex mixture composed of particulate matter (PM), carbon monoxide, methane, nitrous oxide, and polyaromatic hydrocarbons, among others [5], which are linked to arrhythmias [6]. Benzo[a]pyrene is a polyaromatic hydrocarbon and known carcinogen in animal models and i s implicated in breast cancer, lung cancer, liver cancer, and skin cancer [7]. Therefore, the further impact of BaP on the cardiovascular system merits further investigation. (Source: Journal of Molecular and Cellular Cardiology)
