Viscoelastic properties of clot formation and their clinical impact in East Asian versus Caucasian patients with stable coronary artery disease: a COMPARE-RACE analysis
In conclusion, this is the first study to demonstrate different viscoelastic properties of clot between East Asian and Caucasian patients with stable CAD. The platelet–fib rin clot strength was significantly associated with MACE in these patients and was significantly lower in East Asians. Future studies are warranted to further explore the mechanistic explanation and clinical importance of these findings.

Impacts of in-hospital workflow on functional outcome in stroke patients treated with endovascular thrombectomy
This study aimed to evaluate the impacts of in-hospital workflow on functional outcomes after thrombectomy. Patients were enrolled from a multi-center registry program in China. Based on in-hospital managing procedure and personnel involved, two workflow models, neurologist-dominant and non-neurologist-dominant, were identified in the participating centers. Favorable outcome was defined as a mRS score of ≤ 2 at 90 days of stroke onset. After patients being matched with propensity score matching (PSM) method, ratios of favorable outcomes and symptomatic intracerebral hemorrhage (sICH) were compared between patients ...

Incidence and consequences of systemic arterial thrombotic events in COVID-19 patients
AbstractA high incidence of thrombotic events, particularly deep vein thrombosis and pulmonary embolism, has been clearly documented in COVID-19 patients. In addition, small series of patients with coronary, cerebrovascular and peripheral arterial thrombotic events have also been reported, but their true incidence and consequences are not well described, and constitute the objective of this study. From February 1st to April 21st, 2020, 2115 COVID-19 patients were treated at Hospital Universitario Fundaci ón Alcorcón (Madrid, Spain), and 1419 were eventually admitted. Patient characteristics and outcomes were collected by...

Right drug, wrong dosage: insights from the PAVE-AF antithrombotic study in older patients with atrial fibrillation
AbstractOptimal antithrombotic treatment of older patients is usually impeded by several prevailing misconceptions. The aim of our study was to assess the type, dosage and predictors of antithrombotic therapy in older patients with non-valvular atrial fibrillation (NVAF). PAVE-AF was a prospective, cross-sectional study, including NVAF patients ≥ 80 years from 30 participating centers. Demographic data, comorbidities and treatment patterns were documented in a single visit. Patients treated with non-vitamin K oral anticoagulants (NOACs) were further classified into three dosing categories (recommended, underdosing and o...

Hyperacute multi-organ thromboembolic storm in COVID-19: a case report
We report a 66-year-old female patient with post-mortem diagnosis of COVID-19 who presented progressive livedo racemosa, acute renal failure and myocardial injury, as well as an absence of respiratory symptoms. Transthoracic echocardiography showed severe spontaneous echo contrast in the right cardiac chambers and right-sided cardiac overload presumed to result from pulmonary microvascular thrombosis or embolism.d-dimer levels were increased. The patient developed an acute ischemic stroke and died 2 days following presentation despite therapeutic anticoagulation. Her predominantly thromboembolic presentation supports the...

Revascularization outcomes following acute ischemic stroke in patients taking direct oral anticoagulants: a single hospital cohort study
AbstractSuccessful revascularization therapy is of paramount importance in patients suffering acute ischemic stroke (AIS). However, there is currently only limited evidence on revascularization outcomes for patients suffering AIS while treated with direct oral anticoagulants (DOACs). The aim of our study was to determine the efficacy and safety of intravenous thrombolysis (IVT) and mechanical reperfusion (MeR) in AIS patients taking DOACs, and compare them to randomized clinical trials (RCTs), which included patients without DOAC treatment. In an observational cohort study, we analyzed clinical and radiological outcomes fo...

Heart failure patients have enhanced cerebral autoregulation response in acute ischemic stroke
AbstractThe cerebrovascular effects of a failing heart-pump are largely unknown. Chronic heart failure (HF) might cause pre-conditioning effect on cerebral hemodynamics but not study so far in acute stroke. We aimed to investigate if HF induces effects in dynamic cerebral autoregulation (CA), within 6 h of symptom-onset through chronic stage of ischemic stroke. We enrolled 50 patients with acute ischemic stroke. Groups with (N = 8) and without HF and 20 heathy controls were compared. Arterial blood pressure (Finometer) and cerebral blood flow velocity (transcranial Doppler) were monitored w ithin 6 and at 24 h from ...

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.

Point-of-care testing of coagulation in patients treated with edoxaban
AbstractEdoxaban, alongside other direct oral anticoagulants (DOAC), is increasingly used for prevention of thromboembolism, including stroke. Despite DOAC therapy, however, annual stroke rate in patients with atrial fibrillation remains 1 –2%. Rapid exclusion of relevant anticoagulation is necessary to guide thrombolysis or reversal therapy but, so far, no data exists on the effect of edoxaban on available point-of-care test systems (POCT). To complete our previous investigation on global coagulation-POCT for the detection of DOAC, we evaluated whether CoaguChek®-INR (CC-INR) is capable of safely ruling out edoxaban co...

Acute revascularization treatments for ischemic stroke in the Stroke Units of Triveneto, northeast Italy: time to treatment and functional outcomes
AbstractIt is not known whether the current territorial organization for acute revascularization treatments in ischemic stroke patients guarantees similar time to treatment and functional outcomes among different levels of institutional stroke care. We aimed to assess the impact of time to treatment on functional outcomes in ischemic stroke patients who received intravenous thrombolysis (IVT) alone, bridging (IVT plus thrombectomy), or primary thrombectomy in level 1 and level 2 Stroke Units (SUs) in Triveneto, a geographical macroarea in Northeast of Italy. We conducted an analysis of data prospectively collected from 512...
