Fatal Adverse Events of Dabigatran Combined With Aspirin in Elderly Patients: An Analysis Using Data From VigiBase
Conclusion: The fatal adverse events associated with the combined use of dabigatran and aspirin in elderly patients were mainly serious bleeding events, which often occurred within 1 month. Most of these cases had medication errors and most of the patients had multiple diseases, medications, or other conditions at the same time that increase the risk of bleeding. It is suggested that prescription of dabigatran and aspirin in elderly patients should go along with alertness for medication errors, care for correct dose or control of other bleeding risk factors, and the combined medication time should be as short as possible ...

Predictors of Gastrointestinal Bleeding Among Patients with Atrial Fibrillation After Initiating Dabigatran Therapy
ConclusionThe risk of GI bleeding in patients receiving dabigatran is highly associated with increased age and cardiovascular, renal, and other comorbidities, even after adjusting for other factors. Fewer than 50% of patients restarted an anticoagulant after experiencing a GI bleed. Clinicians should continue to monitor for these risk factors or consider whether alternative therapies may be appropriate.

Primary Prevention of Ischaemic Stroke in Atrial Fibrillation: New Oral Anticoagulant Drugs for all?
Abstract Atrial fibrillation (AF) confers a 4.5% risk of stroke per year. The risk of stroke increases with various risk factors and until recently, warfarin has been the gold standard of thromboembolism prophylaxis in AF for many years. The dosage of warfarin requires regular adjustment dependent on the INR, to keep within a narrow therapeutic range of 2.0- 3.0. The INR can be altered by concomitant drugs, foods and alcohol and requires inconvenient blood monitoring. Underanticoagulation places patients at risk of stroke, whilst over-anticoagulation confers significant bleeding risk. Consequently approximately ha...
