ConclusionsThis study is the largest European real-world study ever published on NOACs. It includes all Italian patients treated with NOACs since 2013 accounting for about 1/3 of subjects with AF. The enrolled population consisted of very elderly patients, at high risk of ischemic adverse events. The AIFA registries are consolidated tools that guarantee the appropriateness of prescription and provide important information for the governance of National Health System by collecting real-world data.

Background: It is important to understand the risk of thromboembolism and bleeding in patients with nonvalvular atrial fibrillation (NVAF) receiving direct oral anticoagulants; however, data on risk factors in Japanese patients are limited. Methods: XAPASS (Xarelto Post-Authorization Safety and Effectiveness Study in Japanese Patients with Atrial Fibrillation) is a prospective observational study examining the safety and effectiveness of rivaroxaban in Japanese real-world clinical practice. We investigated risk factors for stroke/noncentral nervous system systemic embolism (non-CNS SE)/myocardial infarction (MI) and major ...

ConclusionIn 20% of failing MT, thrombus cannot be reached/passed. Direct carotid puncture or surgical arterial access could be considered in these cases.In 80% of failing interventions, thrombus can be passed with the device, but the occluded vessel cannot be recanalized. Rescue techniques can be an option. Development of new devices and techniques is necessary to improve recanalization rates. Assessment of pre-existing illness could sensitize for occurring complications.

We present a 42 ‐year‐old male patient with familial transthyretin amyloidosis who suffered an embolic stroke that originated from a left atrial appendage thrombus in the absence of any documented atrial fibrillation. This case highlights atrial mechanical dysfunction in patients with cardiac amyloidosis and th e need to better stratify thrombotic risk in this population with integration of echocardiographic parameters and transesophageal echocardiography.

In this study, we assessed the impact of interacting medication and pharmacogenetic variation to better explain apixaban concentration differences among 358 Caucasian AF patients. Genotyping (ABCG2,ABCB1,CYP3A4*22,CYP3A5*3) was performed by TaqMan assays, and apixaban quantified by mass spectrometry. The typical patient was on average 77.2  years old, 85.5 kg, and had a serum creatinine of 103.1 µmol/L. Concomitant amiodarone, an antiarrhythmic agent and moderate CYP3A/ABCB1 inhibitor, the impaired-function variantABCG2 c.421C  >  A, and sex predicted higher apixaban concentrations whe...

Publication date: Available online 14 January 2020Source: Journal of Pharmaceutical and Biomedical AnalysisAuthor(s): Filipa Gouveia, Joana Bicker, Joana Santos, Marília Rocha, Gilberto Alves, Amílcar Falcão, Ana FortunaAbstractDirect oral anticoagulants (DOACs) have been commonly used for the treatment of venous thromboembolism and for the prevention of stroke in patients with atrial fibrillation. Despite not being initially recommended, monitoring DOACs plasma concentrations is now recognized as essential in emergency situations and in special populations. Moreover, the inter-individual variability f...

In this study, we evaluated the correlation between LAA morphology and cardiac function by transthoracic echocardiography in patients with sinus rhythm.Methods and ResultsWe studied 55 patients (36 men, 70  ± 11 years) who underwent cardiac computed tomography and transthoracic echocardiography. The following 4 different morphologies were used to categorize LAA by computed tomography: chicken wing (CW), windsock, cactus, and cauliflower. These morphologies were also classified into CW and non-CW (nonCW) types. There were no significant differences in the left ventricular ejection fraction (63% vs ...

CONCLUSION: We found that even moderate serum levels of NT-proBNP were associated with the risk of total and ischemic strokes among Japanese whose NT-proBNP levels were relatively low compared with Westerners. PMID: 31932552 [PubMed - as supplied by publisher]

CONCLUSION:  Moderate quality evidence suggests lower INR targets reduce bleeding but increase thromboembolism in AF. The data are dominated by East-Asian studies, limiting generalizability to Western populations. Until higher quality data demonstrate otherwise, an INR range of 2 to 3 should remain standard for thromboembolic prophylaxis in AF. PMID: 31940677 [PubMed - as supplied by publisher]

The introduction of the direct oral anticoagulants for stroke prevention in atrial fibrillation and the management of thromboembolism has transformed the care of patients with these disorders. These drugs, which selectively and reversibly inhibit factor Xa or thrombin in the common pathway of the coagulation cascade, have a wide therapeutic window; this allows for simplified dosing regimens without laboratory monitoring of most adult patients as contrasted to vitamin K antagonists. This class of drug is also associated with a lower bleeding risk than vitamin K antagonists, which has been most clearly demonstrated by a 50% ...
