Benefit-risk profile of extended dual antiplatelet therapy beyond 1 year in patients with high risk of ischemic or bleeding events after PCI.
Authors: Wang HY, Gao RL, Xu B, Yang YJ, Yin D, Wang Y, Dou KF Abstract The benefits and harms of dual antiplatelet therapy (DAPT) continuation with aspirin and clopidogrel beyond 1 year after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation for high ischemic or bleeding risk patients remain unclear. All consecutive patients undergoing PCI were prospectively included in the Fuwai PCI Registry from January 2013 to December 2013. We evaluated 7521 patients who were at high risk for thrombotic or hemorrhagic complications and were events free at 1 year after the index procedure. "TWI...

Predicting Adverse Events beyond Stroke and Bleeding with the ABC-Stroke and ABC-Bleeding Scores in Patients with Atrial Fibrillation: The Murcia AF Project.
CONCLUSION:  In AF patients, the ABC-stroke and ABC-bleeding scores demonstrated similar predictive ability for outcomes beyond stroke and bleeding, including MI, acute HF, a composite of cardiovascular events, and all-cause deaths. This is consistent with nonspecificity of biomarkers that predict "sick" patients or poor prognosis overall. PMID: 32506417 [PubMed - as supplied by publisher]

Safety and efficacy of rt-PA treatment for acute stroke in pseudoxanthoma elasticum: the first report
AbstractPseudoxanthoma elasticum is a rare cause for ischaemic stroke. Little is known about acute and secondary prevention strategies in these subjects given the increased risk of gastrointestinal and urinary bleedings. Here we present the case of a 62  years old man affected by pseudoxanthoma elasticum who presented with acute ischaemic stroke and was successfully treated with intravenous thrombolysis. Neurological signs improved after intravenous thrombolysis without bleeding complication. To our knowledge, this is the first case of pseudoxanth oma elasticum—related stroke undergoing intravenous thrombolysis.

Anticoagulation with direct factor Xa inhibitors in transplant recipients: Results from the DRESDEN NOAC REGISTRY (NCT01588119)
After solid organ or hematopoietic stem cell transplantation (HSCT), the risk of arterial or venous thromboembolism (VTE) is high (1 –7). Oral anticoagulation represents the mainstay for stroke prevention in atrial fibrillation (SPAF) and VTE treatment. The pharmacodynamic and pharmacokinetic profiles of vitamin k antagonists (VKA) represent a challenge especially in the setting of transplantation, also due to the high risk of bleeding (8) and due to complex co-medications of transplant recipients.

Associations between model-predicted rivaroxaban exposure and patient characteristics and efficacy and safety outcomes in patients with non-valvular atrial fibrillation
This study aimed to quantify associations between model-predicted rivaroxaban exposure and patient characteristics and efficacy and safety outcomes in patients with non-valvular atrial fibrillation (NVAF), using data from the phase 3 ROCKET AF trial (NCT00403767). In ROCKET AF, 14,2 64 patients with NVAF were randomized to rivaroxaban (20 mg once daily [OD], or 15 mg OD if creatinine clearance was 30–49 mL/min) or dose-adjusted warfarin (median follow-up: 707 days); rivaroxaban plasma concentration was measured in a subset of 161 patients. In this post hoc exposure–resp onse analysis, a multivariate Cox model was u...

Female Sex as a Risk Modifier for Stroke Risk in Atrial Fibrillation: Using CHA2DS2-VASc versus CHA2DS2-VA for Stroke Risk Stratification in Atrial Fibrillation: A Note of Caution.
Abstract Stroke prevention is a key clinical concern in the management of patients with atrial fibrillation. Oral anticoagulation treatment reduces the risk of disabling stroke, but the treatment increases the risk of bleeding. For decades, the decision to initiate oral anticoagulation has been guided by clinical risk scoring systems such as the CHADS2 and CHA2DS2-VASc scores. In this narrative review, we focus on the recent discussion of the "Sc" (Sex Category) criterion in the CHA2DS2-VASc score. Epidemiological considerations when assessing stroke rates in cohorts are discussed, and the implications of differen...

Rates, management and outcome of bleeding complications during edoxaban therapy in daily care – results from the DRESDEN NOAC REGISTRY
Edoxaban is licensed in many countries around the world, following successful phase-III trials in stroke prevention in atrial fibrillation (SPAF) and treatment of venous thromboembolism (VTE), but at present, little is known about edoxaban-related bleeding complications in daily care. Using data from a prospective, non-interventional oral anticoagulation registry, we analysed rates, management and outcome of edoxaban-related bleeding. Between 1 October 2011 and 28 February 2019, 996 patients were enrolled in the edoxaban cohort and a total of 891 bleeding events were observed (53.2% ISTH minor, 41.9% clinically relevant no...

Net clinical benefit of antithrombotic therapy in patients with heart failure and sinus rhythm: A network meta-analysis from 5 clinical trials
Heart failure (HF) is associated with an increased incidence of thromboembolic events. Antithrombotic treatment could reduce the stroke risk, whereas increase the bleeding risk. Whether antithrombotic treatment should be a routine therapy for HF and sinus rhythm (SR) patients remains unanswered.

Efficacy and safety of low dose rivaroxaban in patients with coronary heart disease: a systematic review and meta-analysis
AbstractThe mortality effects and risk –benefit profile of low dose rivaroxaban (2.5 mg twice daily) in patients with coronary heart disease are not completely understood. Five randomized controlled trials (26,110 patients) were selected using PubMed and Cochrane library till April 2019. The background antiplatelet therapy was aspirin in 3 trials, P2Y12 inhibitor in 1 trial, and in 1 trial 65% patients received aspirin and 35% were on dual antiplatelet therapy (DAPT). The outcomes of interest were cardiovascular mortality, all-cause mortality, myocardial infarction (MI), stroke and major bleeding events. Random effects ...

Comparing the efficacy and safety of direct oral anticoagulants with vitamin K antagonist in cerebral venous thrombosis
AbstractCerebral venous thrombosis (CVT) causes significant disability and mortality. Current guidelines for CVT management support the initial use of unfractionated heparin or low molecular weight heparin followed by longer-term oral vitamin K antagonist (VKA). There has been increasing, albeit limited, evidence for the use of direct oral anticoagulants (DOAC) as an alternative to VKA. We performed a systematic review and meta-analysis of studies that compared the safety and efficacy of DOACs to VKA in treating CVT. A comprehensive literature search was carried out in Medline, Embase and Cochrane Stroke Group Trials Regis...

Left atrial appendage closure: a balanced management of the thromboembolic risk in patients with hemophilia and atrial fibrillation
AbstractAtrial fibrillation is the most common cardiac arrhythmia and is a major cause of embolic stroke. In patients at high bleeding risk such as those with hemophilia, the thromboembolic prevention is challenging. We herein present three patients affected by moderate to severe hemophilia and atrial fibrillation that were treated in our Institution between March 2018 and September 2019, with percutaneous left atrial appendage closure. In patients with relative or absolute contraindications to long-term anticoagulant therapy, the left atrial appendage closure could represent a reasonable strategy.

Novel approaches to P2Y12 inhibition and aspirin dosing.
Authors: Parker WAE, Storey RF Abstract Aspirin and P2Y12 inhibitors remain commonly prescribed antiplatelet drugs in the treatment of atherothrombotic conditions. Despite established benefits of dual antiplatelet therapy (DAPT) in the setting of acute coronary syndromes, there remains residual ischemic risk in this group and the problem of bleeding complications is an ongoing issue. DAPT with aspirin and ticagrelor has now been studied in other patient groups such as those with concurrent diabetes and stable coronary artery disease, and those undergoing elective percutaneous coronary intervention (PCI). Recent tri...
