SUPPORT ‐AF III: supporting use of AC through provider prompting about oral anticoagulation therapy for AF
AbstractOnly half of atrial fibrillation (AF) patients with elevated stroke risk receive anticoagulation (AC). Electronic health record (EHR) alerts have the potential to close the gap. We designed an outpatient EHR alert (linked to an order set for ordering AC, labs, and specialty referrals) that fired when cardiology and primary care providers (PCPs) saw AF patients not on AC. We assigned all untreated patients seen by cardiology providers and PCPs in the 8 months before and after the alert launch to pre- and post-launch intervention cohorts, respectively. Untreated AF patients seeing other types of providers became co...

Short-term non-vitamin K antagonist oral anticoagulants vs. warfarin in preventing device-related thrombosis after left atrial appendage closure
AbstractUp to now we have had few evidences on the Non-vitamin K Antagonist Oral Anticoagulants (NOACs) ’ efficacy and safety in preventing device-related thrombosis (DRT) after percutaneous left atrial appendage closure (LAAC). After LAAC implantation, short-term anticoagulation (NOACs or warfarin) was prescribed. Baseline clinical characteristics, procedural parameters and postoperative follow up data were collected and compared between the two groups. From May 2014 to June 2018, 361 consecutive patients underwent LAAC implantation in our center. 170 patients received warfarin for 45 days at least after LAAC implantat...

Stroke and presence of patent foramen ovale in sickle cell disease
AbstractSickle cell disease (SCD) is an inherited monogenic hemoglobinopathy characterized by formation of sickle erythrocytes under conditions of deoxygenation. Sickle erythrocytes can lead to thrombus formation and vaso-occlusive episodes that may result in hemolytic anemia, pain crisis and multiple organ damage. Moreover, SCD is characterized by endothelial damage, increased inflammatory response, platelet activation and aggravation, and activation of both the intrinsic and the extrinsic coagulation pathways. Cerebrovascular events constitute an important clinical complication of SCD. Children with SCD have a 300-fold h...

Different endovascular procedures for stroke with isolated M2-segment MCA occlusion: a real-world experience
AbstractAcute ischemic stroke with isolated occlusion of the M2-segment middle cerebral artery (MCA) has not been a focus of trials on mechanical thrombectomy (MT) thus far. We aimed to assess outcomes in stroke patients treated with different endovascular procedures versus direct MT alone for isolated M2-MCA occlusion. We conducted a cohort study on data from 506 stroke patients with isolated M2-MCA occlusion who were enrolled in the Italian Registry of Endovascular Treatment in Acute Stroke cohort. We calculated odds ratio (OR) with confidence interval (CI) of different endovascular procedures (vs direct MT alone) for ...

Comparative effectiveness of direct oral anticoagulants and warfarin for the treatment of left ventricular thrombus
AbstractLeft ventricular (LV) thrombus is a complication of acute endomyocardial injury and chronic ventricular wall hypokinesis, resulting in increased risk of thromboembolic complications. Observational studies support the general safety and efficacy of warfarin for this indication. Limited data exists regarding the use of direct oral anticoagulants (DOACs) for LV thrombus. This retrospective cohort study sought to compare the incidence of thromboembolic events, bleeding rates, and blood product administration in patients receiving a DOAC versus warfarin. A total of 949 patients met inclusion, 180 (19%) received a DOAC a...

Histopathologic findings of vascular damage after mechanical thrombectomy using stent retriever in canine models
This study aimed to analyze the degree and the condition of recovery of wall injury after the acute phase via angiography and histopathological analysis of autopsied canine models. Digital subtraction angiography (DSA) and embolization with autologous thrombus were performed in six canines. The model of arterial occlusion was effective in all target vessels. Mechanical thrombectomy was performed in completely occluded vessels using stent retriever. Follow-up angiographic and histopathologic evaluations were performed 1 month later. Complete recanalization using stent retriever was achieved in four cases. Slight residual ve...

Long-term outcomes of left atrial appendage occlusion in high-risk atrial fibrillation patients: 4-year follow up data
AbstractLong-term follow-up data of left atrial appendage (LAA) occlusion in patients with atrial fibrillation (AF) are sparse. To address these data gaps, we analysed the 4-year outcomes of AF patients following LAA occlusion. The was a retrospective cohort study of high-risk patients with AF who underwent successful implantation of the Amulet device at our center between 2014 and 2017. Study endpoints were the rate of stroke, major bleeding and all-cause mortality. We included 71 patients (35.2% females) with a median age of 78 (IQR 73 –82) years. Over a median follow-up period of 46 (IQR 19–56) months, the annual ra...

Bleeding risk in patients with venous thromboembolic events treated with new oral anticoagulants
AbstractNew oral anticoagulants (NOACs) is the preferred treatment in secondary prophylaxis of venous thromboembolic events (VTE). The aim of this study was to investigate possible risk factors associated with major bleeding in VTE-patients treated with NOACs. In this retrospective register-based study we screened the Swedish anticoagulation registerAuricula (during 2012.01.01 –2017.12.31) to find patients and used other national registers for outcomes. Primary endpoint was major bleeding defined as bleeding leading to hospital care. Multivariate Cox-regression analysis was used to reveal risk factors. 18 219 patients wi...

Clopidogrel increases risk of pneumonia compared with aspirin in acute ischemic minor stroke patients
AbstractAntiplatelet agents may increase the risk of infections via suppressing platelet-mediated immune response. Here we assessed the contribution of clopidogrel versus aspirin to the development of pneumonia during an acute ischemic stroke admission. A retrospective cohort study was conducted of acute ischemic stroke patients who were admitted to our hospital from 2015 to 2018. Included patients received uninterrupted clopidogrel or aspirin therapy and did not take other antiplatelet agents throughout their stay. The interest outcome was development of pneumonia after stroke. Conditional logistic regression model after ...

The administration of rtPA before mechanical thrombectomy in acute ischemic stroke patients is associated with a significant reduction of the retrieved clot area but it does not influence revascularization outcome
AbstractBoth intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) are evidence-based treatments for acute ischemic stroke (AIS) in selected cases. Recanalization may occur following IVT without the necessity of further interventions or requiring a subsequent MT procedure. IVT prior to MT (bridging-therapy) may be associated with benefits or hazards. We studied the retrieved clot area and degree of recanalization in patients undergoing MT or bridging-therapy for whom it was possible to collect thrombus material. We collected mechanically extracted thrombi from 550 AIS patients from four International stroke cente...

Increased intracranial hemorrhage of mechanical thrombectomy in acute ischemic stroke patients with atrial fibrillation
This study aimed to investigate the potential association between AF and outcomes after MT in AIS patients. A post-hoc analysis of a multi-center prospective clinical trial was conducted. Before and after propensity score matching (PSM), the clinical features were compared between patients with and without AF. Multivariable logistic regression and mediation analyses were performed to assess the relationship between AF and ICH. Of the total 245 patients, 123 patients were included in the AF group. After PSM, the AF group showed more retrieval attempts (P = 0.004), comparable favorable outcome (P = 0.493), and mortal...

Routine surveillance of pelvic and lower extremity deep vein thrombosis in stroke patients with patent foramen ovale
AbstractPatent foramen ovale (PFO) is a potential conduit for paradoxical embolization to the systemic atrial circulation of a thrombus originating in the venous system. In a selected group of subjects, the prevalence of deep vein thrombosis (DVT) was assessed. Subjects were identified if they underwent magnetic resonance venography (MRV) pelvis and lower extremity doppler (LE-VDU) for assessment of DVT with PFO. The primary outcome measure was to report the number of patients with paradoxical embolization as their suspected etiology of stroke due to the presence of DVT, which then will be considered as determined stroke. ...
