Sociodemographic factors influence outcomes in children with congenital heart disease (CHD). We predict an association between measures of social isolation and outcomes in infants with complex CHD. These measures, racial (RI) and educational (EI) isolation range from 0 to 1, with 0 being no isolation and 1 being fully isolated within a specific population.

Article Synopsis
  • - Atrial fibrillation (AF) is more common in patients with type 2 diabetes and is linked to worse health outcomes; a trial called Harmony Outcomes was conducted to study the effects of albiglutide, a GLP-1 receptor agonist, on cardiovascular events in these patients.
  • - The trial included nearly 9,500 participants over 1.6 years and found that those with a history of AF had a higher rate of major adverse cardiac events, but albiglutide treatment reduced these events regardless of AF history.
  • - Although both groups on albiglutide experienced fewer AF events than those receiving a placebo, the reduction wasn't statistically significant, indicating that albiglutide can lower cardiovascular risks without

Background: While there are several completed clinical trials that address treatment strategies in patients with symptomatic and recurrent atrial fibrillation (AF), there are no randomized clinical trials that address first-line rhythm control of new-onset AF. Recent data suggest that early initiation of rhythm control within 1 year can improve outcomes.

Methods: In this open-label pragmatic clinical trial nested within the Get with The Guidelines Atrial Fibrillation registry, approximately 3,000 patients with first-detected AF will be enrolled at approximately 200 sites.

Adults with congenital heart disease (CHD) benefit from cardiology follow-up at recommended intervals of ≤ 2 years. However, benefit for children is less clear given limited studies and unclear current guidelines. We hypothesize there are identifiable risks for gaps in cardiology follow-up in children with CHD and that gaps in follow-up are associated with differences in healthcare utilization.
