Abstract 175: Atrial Fibrillation in the USF Resident Clinics: Quality-Driven Medical Therapy Session Title: Poster Session AM
Patients with atrial fibrillation (afib) have a high rate of serious complications including stroke and decompensated heart failure. While patients with afib are five times more likely to suffer a stroke in their lifetime than the general population, this risk can be reduced by 64% with appropriate anticoagulation using warfarin or approved novel oral anticoagulants (NOACs). Reducing the morbidity and mortality from excess strokes is a common interest nationwide due to unsustainable healthcare costs, increasing human resource gaps in medicine, and payment reforms that hold physicians and healthcare organizations financiall...

Clinical Outcomes of Plavix and Generic Clopidogrel for Patients Hospitalized With an Acute Coronary Syndrome Original Articles
Conclusions: Generic clopidogrel was noninferior to Plavix with respect to the composite end point of death and recurrent hospitalization for ACS at 1 year among adults >65 years after an ACS hospitalization. Our findings support generic clopidogrel in ACS, which could lead to substantial healthcare cost savings.

Sex-Specific Comparative Effectiveness of Oral Anticoagulants in Elderly Patients With Newly Diagnosed Atrial Fibrillation Original Articles
Conclusions— The reduced risk of ischemic stroke in patients taking rivaroxaban, compared with dabigatran and warfarin, seems to be limited to men, whereas the higher risk of bleeding seems to be limited to women.

Abstract 236: Coronary Artery Procedures in the Cardiac Catheterization Laboratory After Overnight Call: Are Patients at Higher Risk? Session Title: Poster Session II
Conclusion: There were greater procedural complications when performed post-call compared to no post-call; however, when adjusting for significant baseline variables, there was no significant difference seen between groups. Taking into consideration factors that contributed to procedural complications most likely will improve patient outcomes.

Abstract 244: Revision of the Consent Form for Coronary Angiography Procedures Session Title: Poster Session II
Conclusion: In a representative assessment of coronary angiography and PCI outcomes, some major complications are higher that those reported in international literature. Significant access site bleeding was low, likely explained by the high prevalence of radial procedures. Future iterations of the patient information sheet and consent form may be improved by providing personalized risks.

Abstract 089: Can Medical Claims Accurately Assess Cardiovascular and Bleeding Events in an All-Aged Post-Myocardial Infarction Population? Insights Fom the TRANSLATE-ACS Study Session Title: Poster Session I
Conclusion: Event rates at 1 year were lower for MI, stroke and bleeding when using administrative claims to identify events in comparison with physician adjudication. Administrative claims diagnoses are modestly accurate in identifying recurrent MI and stroke admissions but have limited accuracy in identifying bleeding events, which suggests that an alternative approach is needed to ensure good safety surveillance in cardiovascular studies.

Abstract 127: Differences in Care Patterns, Health Status, and Outcomes of Atrial Fibrillation in Patients With and Without Diabetes: Findings From the ORBIT-AF Registry Session Title: Poster Session I
Conclusions: Among patients with AF, diabetes was associated with worse AF symptoms and lower quality of life, as well an increased risk of death and hospitalizations, but not with the risk of thromboembolic or bleeding events.

Abstract 159: Evaluation of Clinical Outcomes among Nonvalvular Atrial Fibrillation Patients Treated With Warfarin or Rivaroxaban Stratified by Presence or Absence of CKD in a Claims Database Session Title: Poster Session II
Conclusions: This study suggests that, in an adult population with NVAF, rivaroxaban-treated patients had fewer ischemic strokes across all patients, including patients with renal impairment. Rivaroxaban-treated patients also had significantly better outcomes for the composite (VTE, MI, or stroke) measure across all groups. Bleeding rates were comparable across all groups.

Conclusion: In our sample, adherence to NOACs was associated with a reduction in stroke and DVTPE risk but did not substantially increase bleeding risk. Further studies with newer NOACs are warranted.

Effectiveness of Left Atrial Appendage Exclusion Procedures to Reduce the Risk of Stroke: A Systematic Review of the Evidence Original Articles
Conclusions— There is limited evidence that the Watchman device may be noninferior to long-term OAC in selected patients. Data on effectiveness of LAA exclusion devices is lacking in patients ineligible for long-term OAC. Percutaneous LAA devices are associated with high rates of procedure-related harms. Although surgical LAA exclusion during heart surgery does not seem to add incremental harm, there is insufficient evidence of benefit.

Safety and Use of Anticoagulation After Aortic Valve Replacement With Bioprostheses: A Meta-Analysis Original Articles
Conclusions— Contrary to the current guidelines, a meta-analysis of previous studies suggests that anticoagulation in the setting of an aortic bioprosthesis significantly increases bleeding risk without a favorable effect on thromboembolic events. Larger, randomized controlled studies should be performed to further guide this clinical practice.

Dabigatran Versus Warfarin for Atrial Fibrillation in Real-World Clinical Practice: A Systematic Review and Meta-Analysis Original Articles
Conclusions— In real-world clinical practice, dabigatran is comparable with warfarin in preventing ischemic stroke among patients with nonvalvular atrial fibrillation. However, dabigatran is associated with a lower risk for intracranial bleeding relative to warfarin, but—particularly among the elderly—a greater risk for gastrointestinal bleeding. Bleeding outcomes from observational studies are consistent with those from the pivotal Randomized Evaluation of Long-Term Anticoagulation Therapy trial.

Abstract 2: Comparative Effectiveness and Safety of Anticoagulant Therapy With Warfarin, Dabigatran, Apixaban, or Rivaroxaban in Patients With Nonvalvular Atrial Fibrillation Session Title: Abstract Oral Session: QCOR 2016 Young Investigator Awards
Conclusions: Our results demonstrated a lower risk of a thromboembolic event or stroke among dabigatran, apixaban, or rivaroxaban users compared to warfarin users. Among NOACs, risks of a thromboembolic event or stroke were similar. Further studies are needed to clarify the finding of a higher major bleeding risk in warfarin and rivaroxaban users.

Abstract 154: Estimating Treatment Effects in More Than Two Treatment Groups via Propensity Score Weighting: Practical Guidance and Application from Anticoagulant Therapy in Atrial Fibrillation Study Session Title: Abstract Poster Session I and Reception
Conclusions: Our results showed IPTW methods, correctly employed under certain assumptions, are practical and relatively simple tools to control for selection bias and other baseline differences in observational studies evaluating the comparative treatment effects of more than two treatment arms. When preserving sample size is important and in the presence of time-varying confounders, IPTW methods have distinct advantages over propensity matching or adjustment.

Sex Differences in Dabigatran Use, Safety, And Effectiveness In a Population-Based Cohort of Patients With Atrial Fibrillation Original Articles
Conclusions— In real-life practice, women are more frequently treated with low-dose dabigatran, yet a trend toward lower stroke rates in women taking high-dose dabigatran was observed. Men benefit from lower bleeding rates with dabigatran compared with warfarin.
