Association Between Pulse Pressure and Gastrointestinal Bleeding Risk in Atrial Fibrillation Patients: A Retrospective Cohort Analysis

To investigate the association between pulse pressure and the risk of gastrointestinal bleeding in patients with atrial fibrillation.

Study Design: Retrospective cohort analysis of atrial fibrillation patients.
Population: Patients diagnosed with atrial fibrillation.
Outcome Measures: Incidence of gastrointestinal bleeding events.

Elevated pulse pressure is associated with an increased risk of gastrointestinal bleeding in atrial fibrillation patients.

The findings suggest that pulse pressure may serve as a useful marker for assessing bleeding risk in atrial fibrillation patients.

Pulse pressure could be a valuable parameter in evaluating bleeding risk among atrial fibrillation patients.
