AI Article Synopsis

  • - This study analyzed the risk of gastrointestinal (GI) events in patients with atrial fibrillation (AF) using data from over 557,000 patients from 2005 to 2009, finding that about 40% experienced such events, with dyspepsia being the most common.
  • - The incidence rates (IRs) showed a variation based on factors like gender, age, and the CHADS2 score, indicating that older patients and those with higher stroke risk scores had higher rates of GI events.
  • - The findings suggest that healthcare providers should consider a patient's age and additional health conditions when managing AF to better address the risk of GI complications.

Article Abstract

This observational study was conducted to describe the risk of gastrointestinal (GI) events among patients with atrial fibrillation (AF). We analyzed Thomson Reuters MarketScan® data from 2005 to 2009. Subjects aged ≥18 years with ≥ 1 AF diagnosis were selected. GI events were identified from claims with a primary or secondary diagnosis code for any GI condition. The risk of GI events was assessed using cumulative incidence (new GI events/patients with AF without GI condition at baseline) and incidence rates (IRs), calculated as the number of patients with new GI events divided by patient-years of observation. In addition, the CHADS2 score was evaluated at baseline to determine the patient's risk of stroke. A total of 557,123 AF patients were identified. The mean (median) AF patient age was 68.2 years (70); 45% were female. The cumulative incidences of any GI event and dyspepsia were 40% and 19%, respectively. The corresponding IRs were 38.8 and 14.7 events per 100 patient-years. IRs of any GI events for female and male patients were 43.6 and 35.5; for patients in the age groups <65, 65-74, 75-84, and ≥85 years, IRs were 32.3, 38.9, 44.6, and 52.7; for patients with a CHADS2 score of 0, 1-2, 3-4, and 5-6, IRs were 30.3, 41.6, 56.9, and 74.5, respectively. In this large claims database, 40% of AF patients experienced a GI event, predominantly dyspepsia. Physicians should take age and comorbidities into consideration when managing AF patients.

In addition to traditional risk factors, patients with breast cancer are at an increased risk of atrial fibrillation due to cancer itself and certain cancer therapies. Atrial fibrillation in these patients adds to their morbidity and mortality. The precise mechanisms leading to the increased atrial fibrillation in patients with breast cancer are not well understood.

Background: The efficacy of catheter ablation as a treatment approach for patients with concurrent atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) has been inadequately investigated.

Objective: This study's objective was to assess the effectiveness of atrial fibrillation ablation (AFA) in patients with heart failure with preserved ejection fraction.

Methods: Utilizing the TriNetX research network, we identified individuals aged 18 and older with atrial fibrillation (AF) and concurrent heart failure with preserved ejection fraction (HFpEF) from January 1, 2010, to June 1, 2021.
