AI Article Synopsis
- Atrial fibrillation is a common condition affecting 4 million people in the U.S., and understanding how age influences hospitalization patterns is important.
- The study analyzed data from 2009-2010 to compare hospitalization rates, lengths of stay, and patient outcomes between younger (<65 years) and older (≥65 years) patients diagnosed with atrial fibrillation.
- Findings showed that younger patients typically had fewer health complications and were less likely to die in the hospital compared to older patients, who had higher mortality rates and more severe health issues.
Article Abstract
Background: Given that 4 million individuals in the United States have atrial fibrillation, understanding the epidemiology of this disease is crucial. We sought to identify and characterize the impact of age on national atrial fibrillation hospitalization patterns.
Methods: The study sample was drawn from the 2009-2010 Nationwide Inpatient Sample. Patients hospitalized with a principal International Classification of Diseases, 9th Revision discharge diagnosis of atrial fibrillation were included. Patients were categorized as "older" (≥65 years) or "younger" (<65 years) for the purposes of analysis. The outcomes measured included hospitalization rate, length of stay, in-hospital mortality, and discharge status.
Results: We identified 192,846 atrial fibrillation hospitalizations. There was significant geographic variation in hospitalizations for both younger and older age groups. States with high hospitalizations differed from those states known to have high stroke mortality. Younger patients (33% of the sample) were more likely to be obese (21% vs 8%, P < .001) and to use alcohol (8% vs 2%, P < .001). Older patients were more likely to have kidney disease (14% vs 7%, P < .001). Both age groups had high rates of hypertension and diabetes. Older patients had higher in-hospital mortality and were more likely to be discharged to a nursing or intermediate care facility.
Conclusions: Younger patients account for a substantial minority of atrial fibrillation hospitalizations in contemporary practice. Younger patients are healthier, with a different distribution of risk factors, than older patients who have higher associated morbidity and mortality.

Approximately one-third of patients with breast cancer have comorbidities at the time of their diagnosis. Recommendations for managing metastatic breast cancer are usually based on the results of clinical trials, which often limit patients with comorbidities. However, comorbidities greatly influence the quality of life, patient survival rate and treatment choice, particularly in older patients.

Purpose: In totally endoscopic off-pump left atrial appendage (LAA) closure and surgical ablation, securing the operative field is sometimes difficult in some patients because of a narrow working space caused by an elevated diaphragm or ventricles. In this study, we aimed to investigate the effectiveness of a method that facilitates securing the operative field using an artificial pneumothorax.
Methods: We analyzed 71 consecutive patients who underwent totally endoscopic off-pump LAA closure and bilateral pulmonary vein isolation.

Background: The net benefit of oral anticoagulation in patients with end-stage renal disease on hemodialysis (HD) is uncertain. In recent years, left atrial appendage closure (LAAC) has emerged as an alternative to oral anticoagulation; however, there is scant evidence of LAAC in patients on HD.
Objectives: This study aimed to assess the feasibility and safety of LAAC in patients on HD.
Objectives: This study aimed to develop a prediction model for the detection of early sepsis-associated acute kidney injury (SA-AKI), which is defined as AKI diagnosed within 48 hours of a sepsis diagnosis.
Design: A retrospective study design was employed. It is not linked to a clinical trial.
