Abstract 22: Impact of CHA2DS2-VASc Risk Factors on Anticoagulant Prescription in Patients with Atrial Fibrillation: Insights From the NCDR(R) PINNACLE Registry Session Title: Abstract Oral Session
Conclusions: Among this cohort of AF patients with an indication for OAC use, older age and HTN were strongly associated with greater OAC use whereas female gender and vascular disease were associated with less OAC use. Further investigation is needed to understand reasons for these differences in how risk factors influence decisions to provide OAC, such as patient or provider preference or gender bias.

Abstract 14: Clinical Characteristics and Treatment Patterns of Medicaid Patients with Atrial Fibrillation: Insights From the ORBIT-AF I Registry Session Title: Concurrent Session IIB: Oral Abstracts - Quality of Care
Conclusions: In a contemporary, community-based AF cohort, Medicaid patients had a greater comorbidity burden and higher stroke risk, yet were less likely to receive OAC compared with those with other forms of insurance.

Abstract 263: The Risk of Stroke or Systemic Embolism for Antithrombotic Treatment Episodes among Non-Valvular Atrial Fibrillation (NVAF) Patients Session Title: Poster Session II
Conclusion: Warfarin TTR ≥55% was associated with the greatest reduction in stroke/SE among the antithrombotic treatment groups examine here. Future studies should examine modifiable factors to improve outcomes for patients with warfarin TTR <55% or those who are off antithrombotic therapy.

Risks and Benefits of Anticoagulation in Atrial Fibrillation: Insights From the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF) Registry Original Articles
Conclusions— In community-based outpatients with AF, use of OAC was high and driven by not only predominantly stroke but also bleeding risk. Stroke risk significantly affects OAC use among those with low bleeding risk, whereas those with high bleeding risk demonstrate consistently lower use of OAC regardless of stroke risk.

Abstract 156: Body Mass Index and Outcomes among Patients with Atrial Fibrillation from the ATRIA2-CVRN Study Poster Session II
In conclusion, overweight and moderate obesity appear protective for all-cause mortality in at-risk AF patients during off-warfarin periods, but these effects do not appear to be mediated by reduced risk of thromboembolism or major bleeding.

Abstract 217: How well does the CHADS2 Stroke Risk Score Predict Major Hemorrhage in Patients with Atrial Fibrillation? Poster Session II
Conclusions: Although some clinical markers of stroke risk such as those included in the CHADS2 risk score are also associated with increased hemorrhage risk, the CHADS2 risk score should not be used instead of a validated hemorrhage risk tool to estimate hemorrhage risk.
