Background: Despite clear associations between arrhythmia burden and cardiovascular risk, clinical risk scores that predict cardiovascular events do not incorporate individual-level arrhythmia characteristics from long-term continuous monitoring (LTCM).
Objectives: This study evaluated the performance of risk models that use data from LTCM and patient claims for prediction of heart failure (HF) and ischemic stroke.
Methods: We retrospectively analyzed features extracted from up to 14 days of LTCM electrocardiogram (ECG) data linked to patient-level claims data for 320,974 Medicare beneficiaries who underwent ZioXT ambulatory monitoring.
Article Synopsis
- A study was conducted to compare changes in brain imaging and cognitive function between atrial fibrillation (AF) patients treated with catheter ablation and those receiving medical therapy.
- The research involved 12 patients undergoing ablation and 11 on medical management, assessing white matter hyperintensity burden (WMHb) and cortical thickness over 6 weeks and 1 year.
- Findings showed that patients who underwent ablation had less cortical thinning in areas linked to Alzheimer's risk compared to those on medical therapy, highlighting the potential impact of AF treatment on cognitive health.
Background: Long-term rhythm monitoring to detect atrial fibrillation (AF) following a cryptogenic stroke (CS) is well established. However, the burden of organized atrial arrhythmias in this population is not well defined.
Objective: The purpose of this study was to assess the incidence and risk factors for organized atrial arrhythmias in patients with CS.
Atrial fibrillation is the most common atrial arrhythmia and accounts for a significant burden of cardiovascular disease globally. With advances in implanted and wearable cardiac monitoring technology, it is now possible to readily and accurately quantify an individual's time spent in atrial fibrillation. This review summarizes the relationship between atrial fibrillation burden and adverse cardiovascular and cerebrovascular outcomes and discusses the role of catheter ablation to mitigate the morbidity and mortality associated with greater burden of atrial fibrillation.

Stakeholder engagement can help understand the overall adolescent mental health ecosystem and adapt existing evidence-based interventions for the youth.
Objective: To understand the overall mental health needs of adolescents in Botswana and the necessary adaptations required for an adolescent lay counselor based intervention in the country.
Background And Purpose: Initial reports suggest a significant risk of thrombotic events, including stroke, in patients hospitalized with coronavirus disease 2019 (COVID-19). However, there is little systematic data on stroke incidence and mechanisms, particularly in racially diverse populations in the United States.
Methods: We performed a retrospective, observational study of stroke incidence and mechanisms in all patients with COVID-19 hospitalized from March 15 to May 3, 2020, at 3 Philadelphia hospitals.
