Special MRI scan could identify stroke risk in people with atrial fibrillation
Atrial fibrillation is a heart rhythm disorder that affects millions of people. It can make you feel lousy. Even worse, it can cause potentially disabling or deadly strokes. A special MRI scan may — I stress the “may” — help identify people with atrial fibrillation who are at high risk of having a stroke. This could help many people with this condition to avoid taking warfarin or other clot-preventing medications for life. A normal heartbeat starts in a cluster of cells called the pacemaker. It sits in the heart’s upper right chamber (the right atrium). These cells generate a pulse of electricity that...

Outcome of men and women after atrial fibrillation and stroke
ConclusionsThere were no gender differences in long‐term mortality after stroke related to AF. Men were significantly more often prescribed anticoagulants before stroke, a finding that indicates the need for further studies.

Recognition of posterior circulation stroke
ConclusionsDespite being of typical age for multiple cardiovascular conditions the PC‐ICH patients less often have a previous history of AF or dyslipidemia than IS patients do. The vomiting PC‐ICH patient with hypertensive BP values often has headache and a red flag for hemorrhage is warfarin treatment.

Dabigatran etexilate: management in acute ischemic stroke.
Abstract A 54-year-old man treated with dabigatran experienced new onset of a stroke with a score of 9 on the National Institutes of Health Stroke Scale. Administration of recombinant tissue plasminogen activator (rtPA) was not recommended because of the dabigatran therapy. Angiography showed occlusion of the left middle cerebral artery by an embolic thrombus. Suction thrombectomy achieved flow through the inferior division of the artery. Computed tomography of the head showed possible intracranial hemorrhage, and dabigatran reversal was attempted with prothrombin complex concentrate and recombinant factor VIIa. C...

Reversing the effects of the new anti-clotting drugs
The oral anticoagulant warfarin (Coumadin) became available for prescription in 1954. This anti-clotting drug commanded national attention when President Dwight Eisenhower received the drug as part of his treatment following a heart attack. No other oral anticoagulant was successfully developed and marketed in the United States until 2010. Warfarin is a dangerous drug. Along with insulin, it is responsible for the most emergency hospitalizations due to adverse drug reactions. Whereas insulin causes low blood sugar, warfarin is notorious for the complication of major bleeding. Warfarin is plagued by hundreds of drug-drug an...

Early introduction of direct oral anticoagulants in cardioembolic stroke patients with non-valvular atrial fibrillation
AbstractDirect oral anticoagulants (DOACs) are superior to warfarin in reduction of the intracranial bleeding risk. The aim of the present study was to assess whether early DOAC introduction (1 –3 days after onset) in stroke patients with non-valvular atrial fibrillation (nVAF) may be safe and effective, compared with DOAC introduction after 4–7 days. We conducted a prospective analysis based on data collected from 147 consecutive nVAF patients who started DOAC within 7 days after stro ke onset. In all patients, we performed pre-DOAC CT scan 24–36 h after onset and follow-up CT scan at 7 days after DOAC introduction...

Cost-Effectiveness of Bridging Anticoagulation Among Patients with Nonvalvular Atrial Fibrillation
ConclusionsOutpatient bridging anticoagulation can be beneficial and cost-effective for a subset of patients with nonvalvular atrial fibrillation during interruption or initiation of warfarin. Admission for bridging should be avoided.

Efficacy and Safety of Direct Oral Factor Xa Inhibitors in 795 Morbidly Obese Patients
Conclusions: Our study is the largest study examining morbidly obese patients on DOACS and provides further evidence of comparable efficacy and safety of the direct oral anti-Xa inhibitors, compared to warfarin, in morbidly obese patients with AF and VTE.DisclosuresKushnir: Janssen: Research Funding.

Non-vitamin K oral anticoagulants in nonvalvular atrial fibrillation: A network meta-analysis.
CONCLUSIONS: This study adds an attempt for treatment ranking of both efficacy and safety outcomes. Future trials comparing directly NOACs are needed in order to provide conclusive proofs for these results and not only circumstantial evidence offered by a network meta-analysis.

Correlates and outcomes of warfarin initiation in kidney transplant recipients newly diagnosed with atrial fibrillation
In the kidney transplant population with atrial fibrillation (AF), evidence regarding the effectiveness and safety of warfarin treatment is lacking. We used fee-for-service Medicare claims to identify kidney transplant recipients with newly diagnosed AF from the United States Renal Data System. Warfarin use within 30 days of AF diagnosis was ascertained from Medicare Part D prescription claims (2007–11) or using a validated algorithm (1997–2011). The study end points were (i) the composite of death, stroke or gastrointestinal bleed, (ii) death and (iii) death-censored graft failure. Warfarin user and non-user g...

New onset postoperative atrial fibrillation and early anticoagulation after cardiac surgery.
CONCLUSIONS: POAF after cardiac surgery was associated with high risk of MACE. Early anticoagulation may be justified in POAF patients to secure a long-term outcome after cardiac surgery. PMID: 28990803 [PubMed - as supplied by publisher]

Delayed recognition of Type II decompression sickness in a diver with chronic atrial fibrillation
CONCLUSION: The presence of symptoms attributed to a stroke immediately after a scuba dive should not deter a trial of HBO2 therapy. The delay in starting HBO2 therapy is concerning and perhaps the reason recovery was delayed and the need for repetitive HBO2 therapies.PMID:35580489
