Comparison of 4 different strategies of DAPT after PCI in ACS real world population from a Northern Italy registry
AbstractAim of the study was to compare four different strategies of dual antiplatelet therapy (DAPT) in patients with acute coronary syndromes (ACS) treated with PCI. DAPT with Clopidogrel, Ticagrelor and Prasugrel has proved to be effective in patients with ACS treated with percutaneous coronary intervention (PCI) by reducing major adverse cardiovascular outcomes (MACE). However, the effect of the different strategies in a real-world population deserves further verification. A retrospective analysis of 2404 discharged ACS patients treated with PCI was performed, with a median follow-up of 1 year. The study population w...

Effectiveness and safety of apixaban therapy in daily-care patients with atrial fibrillation: results from the Dresden NOAC Registry
AbstractThe effectiveness and safety of apixaban for stroke prevention in atrial fibrillation (SPAF) demonstrated in ARISTOTLE needs to be confirmed in daily care. To evaluate effectiveness and safety of apixaban therapy in SPAF patients in daily care, we used data from an ongoing, prospective, non-interventional registry of more than 3000 patients on novel oral anticoagulants in daily care. Between 1 December 2012 and 31 August 2015, 514 patients receiving apixaban were enrolled. During a mean follow-up of 803.5 ± 228.9 days, the combined endpoint of stroke/transient ischaemic attack/systemic embolism occurred at a ...

Determination of non-Vitamin K oral anticoagulant (NOAC) effects using a new-generation thrombelastography TEG 6s system
AbstractNon vitamin K oral anticoagulants (NOACs) do not require regular monitoring but information about their pharmacodynamic effect may be importantin situations like trauma, stroke oremergent surgery. Currently, no standardized point-of-care test is available to evaluate the anticoagulant effects of NOACs. We evaluated the anticoagulant effect of NOACs with the next generation point-of-care TEG assay (TEG ® 6S) based on a fully-automated thrombelastography system. We used two TEG® 6S assays, the DTI assay and Anti-Factor Xa (AFXa) assay, to detect anticoagulant effects and classify NOACs. Blood from healthy volunteer...

Net clinical benefit of dabigatran vs. warfarin in venous thromboembolism: analyses from RE-COVER ® , RE-COVER™ II, and RE-MEDY™
AbstractThe direct oral anticoagulants, e.g., dabigatran etexilate (DE), are effective and well tolerated treatments for venous thromboembolism (VTE). Net clinical benefit (NCB) is a useful concept in weighing potential benefits against potential harm of comparator drugs. The NCB of DE vs. warfarin in VTE treatment was compared. Post-hoc analyses were performed on pooled data from the 6-month RE-COVER ® and RE-COVER™ II trials, and data from the RE-MEDY™ trial (up to 36 months), to compare the NCB of DE (150 mg twice daily) and warfarin [target international normalized ratio (INR) 2.0–3.0]. Patients (≥18 years ol...

Feasibility of rapid measurement of Rivaroxaban plasma levels in patients with acute stroke
AbstractPlasma levels of Rivaroxaban (RivLev) might be useful to guide therapeutic decisions in patients with acute stroke under Rivaroxaban. A prerequisite for the potential clinical usefulness is their rapid availability in emergency situations. Single-center explorative analysis from the Novel-Oral-Anticoagulants-in-Stroke-Patients-registry (NOACISP, cinicaltrials.gov:NCT02353585). We included consecutive patients with acute ischemic or hemorrhagic stroke under Rivaroxaban (last intake<48 h) in which RivLev determined by an automated anti-factor Xa-based chromogenic assay (Hyphen-Biomed, France) are available. Prim...

Impact of valvular heart disease on oral anticoagulant therapy in non-valvular atrial fibrillation: results from the RAMSES study
AbstractThe definition of non-valvular atrial fibrillation (NVAF) is controversial. We aimed to assess the impact of valvular heart disease on stroke prevention strategies in NVAF patients. The RAMSES study was a multicenter and cross-sectional study conducted on NVAF patients (ClinicalTrials.gov identifier NCT02344901). The study population was divided into patients with significant valvular disease (SVD) and non-significant valvular disease (NSVD), whether they had at least one moderate valvular disease or not. Patients with a mechanical prosthetic valve and mitral stenosis were excluded. Baseline characteristics and ora...

Prescribing trends of atrial fibrillation patients who switched from warfarin to a direct oral anticoagulant
AbstractDirect oral anticoagulant (DOAC) agents offer several lifestyle and therapeutic advantages for patients relative to warfarin in the treatment of atrial fibrillation (AF). These alternative agents are increasingly used in the treatment of AF, however the adoption practices, patient profiles, and reasons for switching to a DOAC from warfarin have not been well studied. Through the Michigan Anticoagulation Quality Improvement Initiative, abstracted data from 3873 AF patients, enrolled between 2010 and 2015, were collected on demographics and comorbid conditions, stroke and bleeding risk scores, and reasons for anticoa...
