Ticagrelor, but not clopidogrel active metabolite, displays antithrombotic properties in the left atrial endocardium

ConclusionTicagrelor, but not CAM, reduces expression and activity of TF and PAI-1 in LAA endocardial cells isolated from patients with AF, indicating possible local antithrombotic effects. Such pleiotropic properties of ticagrelor may contribute to a reduction in thromboembolic complications in patients with AF.

This study aims to investigate the utility of TTE as part of AIS workup.Methods: We collected data on consecutive patients with AIS who were admitted to our institution between 07/01/2016 and 09/30/2017. Patients were included based on neuroimaging-documented AIS, age>18 and neuroimaging studies. Primary endpoint was the proportion of cases in which TTE yielded relevant finding, defined as Atrial Septa Defect or Patent Foramen Ovale, left atrial enlargement, left ventricular thrombus or ejection fraction of

Authors: Xie X, Li T Abstract Objective: We investigated the risk of ischaemic stroke in patients with 1 another stroke risk factor (i.e. CHA2DS2-VASc score =1 [males] or 2 [females]) and the impact of different component risk factors.Methods: Database were collected from two hospitals in the city of Hohhot in china. Among 3148 Nonvalvular AF patients not on antiplatelet or anticoagulant therapy, we evaluated males with a CHA2DS2-VASc score of 1 and females with a CHA2DS2-VASc score of 2. The clinical endpoint was the occurrence of ischaemic stroke.Results: Among 546 AF male patients with a CHA2DS2-VASc scor...

AbstractThere were limited studies comparing the anterior (AC) and posterior (PC) circulation acute ischemic strokes (AIS). Our study aimed to evaluate distinct features of AC and PC strokes regarding clinical, vascular risk, pathogenesis and outcome factors after endovascular procedures. This multicenter prospective study registered 873 patients with acute large occlusion of anterior circulation stroke (ACS) and posterior circulation stroke (PCS). Patients who underwent endovascular procedures were included in this study. The differences in ACS and PCS regarding baseline characteristics, post-operative intracranial hemorr...

Abstract BACKGROUND AND OBJECTIVES: The aim of this retrospective cohort study was to develop a new score (RA-CHADSV) (rheumatoid arthritis - congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke/transient ischemic attack/thromboembolism, and vascular disease), modified from the CHA2DS2-VASc score (congestive heart failure, hypertension, age ≥75 years (doubled), diabetes mellitus, stroke/transient ischemic attack (doubled), vascular disease, age 65-74 years, and female), in predicting the risk of ischemic stroke in rheumatoid arthritis (RA) patients without atrial fibrillation (AF)...

Background: Left atrial appendage (LAA) closure is primarily performed in patients who have contraindications to anticoagulants. However, anticoagulants are recommended for the first few weeks after LAA closure to prevent the device related thrombus. Purpose of this study was to evaluate if short term use of anticoagulant is safe and effective after LAA closure in patients with a history of intracranial hemorrhage. Methods: It is a retrospective observational study done at a single center. Baseline characteristics, perioperative, and postoperative complications of patients with a history of intracranial hemorrhage and Watc...

AbstractThe efficacy of reperfusion therapy (RT) using intravenous infusion of recombinant tissue plasminogen activator and/or endovascular therapy for minor ischemic stroke (MIS) has not yet been established. The present study aimed to elucidate the clinical features of MIS patients with atrial fibrillation (AF) and examine whether they could be potential candidates for RT. Data of MIS patients, defined as those with a score  ≤ 5 on the National Institute of Health Stroke Scale, were extracted from patients admitted to our hospital between 2006 and 2018, and clinical characteristics were compared between ...

Conclusion: DOAC discontinuation rates varied significantly and appeared related to drug-specific side effects, patient-initiated discontinuation, and bleeding. We observed longer-term administration of apixaban, suggesting that this drug is better tolerated than dabigatran or rivaroxaban. PMID: 32011180 [PubMed - as supplied by publisher]

Conclusion and Relevance: Female patients with a high stroke risk were less likely to receive guideline-recommended treatment. This study provides new information on prescribing trends within the Australian setting and highlights the opportunity to improve the management of female patients with AF and 1 or more additional stroke risk factors.

In conclusion, elderly and frail patients requiring anticoagulation for AF or VTE are at higher risk of adverse outcomes, but also have a higher absolute benefit from OAC. Important practical aspects to improve efficacy and safety in this challenging population are summarized in this overview. PMID: 32000266 [PubMed - as supplied by publisher]

Abstract BACKGROUND: Recent publications suggest that left atrial (LA) myopathy is a potential source of thromboembolism, independent of atrial fibrillation. AIMS: We sought to investigate whether the presence of atrial premature activity after an ischaemic stroke is associated with LA remodelling and dysfunction, and might be a surrogate marker of LA myopathy. METHODS: After an ischaemic stroke or a transient ischaemic attack, patients without known atrial fibrillation or overt heart disease were included prospectively in the study. All patients had a standard workup, including ambulatory Holter electro...
