Atrial fibrillation versus. atrial myopathy in thrombogenesis: Two sides of the same coin?

Trends Cardiovasc Med

January 2025

Liverpool Centre for Cardiovascular Science at University of Liverpool, Liverpool John Moores University and Liverpool Heart and Chest Hospital, Liverpool, United Kingdom; Department of Clinical Medicine, Aalborg University, Aalborg, Denmark; Medical University of Bialystok, Bialystok, Poland.

Atrial fibrillation (AF) and atrial myopathy are recognized contributors to cardiovascular morbidity, particularly ischemic stroke. AF poses an elevated risk of thrombogenesis due to irregular heart rhythm leading to blood stasis and clot formation. Atrial myopathy, marked by structural and functional alterations in the atria, is emerging as a crucial factor influencing thromboembolic events, independently of AF.

Adequate secondary prevention in survivors of intracerebral hemorrhage (ICH) who also have atrial fibrillation (AF) is a long-standing clinical dilemma because these patients are at increased risk of recurrent ICH as well as of ischemic stroke. The efficacy and safety of oral anticoagulation, the standard preventive medication for ischemic stroke patients with AF, in ICH patients with AF are uncertain. PRESTIGE-AF is an international, phase 3b, multi-center, randomized, open, blinded end-point assessment (PROBE) clinical trial that compared the efficacy and safety of direct oral anticoagulants (DOACs) with no DOAC (either no antithrombotic treatment or any antiplatelet drug).

Article Synopsis
  • The study investigates the impact of the triglyceride-glucose index (TyG) on mortality rates in ICU patients who experienced their first-ever strokes.
  • It utilizes data from a large database and local ICUs, employing statistical models to analyze the relationship between TyG levels and both ICU and hospital mortality as well as length of stay.
  • Findings indicate that higher TyG levels significantly correlate with increased mortality risk, and machine learning models based on TyG demonstrate promising predictive capabilities for ICU outcomes.

Introduction: Pulsed-field ablation (PFA) is a novel modality for pulmonary vein isolation in patients with atrial fibrillation (AF). We describe the initial uptake and experience of PFA using a pentaspline catheter across selected National Health Service England (NHSE) centres.

Methods: Data collected by NHSE Specialised Services Development Programme regarding AF ablation procedures using a single-shot, pentaspline, multielectrode PFA catheter (FARAWAVE, Boston Scientific) between June 2022 and August 2024 were aggregated and analysed to examine procedural metrics, acute efficacy and safety outcomes over 3-month follow-up.

Article Synopsis
  • Many patients with atrial fibrillation (AF) are not receiving or are stopping oral anticoagulation therapy, despite its importance for stroke prevention.
  • While direct oral anticoagulants (DOACs) are available, issues like bleeding risks, poor compliance, and aversion to treatment contribute to this problem.
  • A recent expert consensus guide highlights left atrial appendage closure (LAAC) as a safe alternative for stroke prevention in patients who cannot use long-term anticoagulation, detailing the devices, implantation technique, and follow-up requirements for non-implanting physicians.

Introduction: Classical risk factors such as hypertension, hypercholesterolemia, pre-diabetes, diabetes and obesity can predict adverse cardiovascular events, but they are less prognostic in patients aged < 60 years. Polygenic risk scores (PRS) can be effective in predicting adverse coronary events in younger and middle-aged patients. Our main aim is to assess the utility of a new PRS created for the Polish population in predicting mortality during an 8-year follow-up in the nationwide LIPIDOGEN2015 population.

Background: Patients with atrial fibrillation (AF) frequently experience multimorbidity. Cluster analysis, a machine learning method for classifying patients with similar phenotypes, has not yet been used in South Asian AF patients.

Methods: The Kerala Atrial Fibrillation Registry is a prospective multicentre cohort study in Kerala, India, and the largest prospective AF registry in South Asia.

Poor clinical outcomes associated to multimorbidity, frailty and malnutrition in patients with atrial fibrillation.

J Nutr Health Aging

January 2025

Department of Hematology, Hospital Clínico Universitario Virgen de la Arrixaca, University of Murcia, Instituto Murciano de Investigación Biosanitaria (IMIB-Arrixaca), Murcia, Spain.

Article Synopsis
  • A study was conducted on atrial fibrillation (AF) patients starting vitamin K antagonist (VKA) therapy to determine the effect of comorbidities, frailty, and malnutrition on clinical outcomes.
  • The research found that a majority of patients had multiple health issues, and frailty significantly increased the risks for major bleeding and death, while malnutrition heightened the risk for strokes and overall mortality.
  • These findings underline the importance of addressing these factors in AF patients to improve their health outcomes during VKA treatment.

Article Synopsis
  • Atrial fibrillation (AF) patients in the ICU experience significant mortality risks, heavily influenced by glycaemic variability (GV), which relates to poor sugar control and can worsen their prognosis.
  • Higher GV levels correlate with increased all-cause mortality at 30, 90, and 360 days after ICU admission, indicating a need for better glycaemic management.
  • Machine learning models, particularly using light gradient boosting, show promise in predicting 30-day mortality among AF patients based on GV and other clinical features.

Background: Diastolic heart failure (DHF) and type 2 diabetes mellitus (T2DM) often coexist, causing increased mortality rates. Glycaemic variability (GV) exacerbates cardiovascular complications, but its impact on outcomes in patients with DHF and T2DM remains unclear. This study examined the relationships between GV with mortality outcomes, and developed a machine learning (ML) model for long-term mortality in these patients.

Long-term risks and benefits of oral anticoagulation in atrial fibrillation patients with cancer: A report from the GLORIA-AF registry.

Eur J Clin Invest

Liverpool Centre for Cardiovascular Science at University of Liverpool, Liverpool John Moores University, and Liverpool Heart and Chest Hospital, Liverpool, UK.

Background: Anticoagulation therapy in patients with atrial fibrillation (AF) and concomitant cancer can be challenging due to the significantly increased risk of both embolism and bleeding. Moreover, the benefits and risks of vitamin K antagonists (VKA, eg. warfarin) versus non-vitamin K antagonist oral anticoagulants (NOACs) in such patients are less well understood.

Aims: The CHA2DS2VASc score is recommended for stroke risk stratification in patients with atrial fibrillation (AF). This score assigns one extra point to female sex based on evidence from the early 2000s, suggesting higher thromboembolic risk in women. This incremental risk of thromboembolism in women has decreased over time between 2007 and 2018, becoming non-significant in recent years.

Clinical risk scores that predict outcomes in patients with atrial fibrillation (AF) have modest predictive value. Machine learning (ML) may achieve greater results when predicting adverse outcomes in patients with recently diagnosed AF. Several ML models were tested and compared with current clinical risk scores on a cohort of 26,183 patients (mean age 70.

Article Synopsis
  • The study aimed to determine the effectiveness and safety of starting direct oral anticoagulants (DOACs) early versus delayed in patients with acute ischaemic stroke and atrial fibrillation.
  • Conducted as a multicenter, randomized controlled trial across 100 UK hospitals, 3,648 patients were initially assigned to either early initiation (within 4 days) or delayed initiation (7-14 days) of anticoagulation.
  • The primary outcome measured was the incidence of complications like recurrent stroke or bleeding within 90 days, with results being analyzed by an independent committee to ensure objectivity.

Atrial fibrillation (AF) is common and warrants consideration of oral anticoagulant (OAC) medication. Usually, the decision is straightforward, following the pathway outlined in the European Society of Cardiology's guideline; however, certain situations fall outside of this evidence base - such as a diagnosis of subclinical AF made via implanted devices or wearable electrocardiogram monitors, or alternatively diagnosis of 'secondary AF' following a major stressor. Subclinical AF is associated with stroke, though not to the extent of clinical AF, and the benefits of anticoagulation appear to be lower.
