Abstract
BACKGROUND Intravenous thrombolysis (IVT) is an effective stroke therapy that remains underused. Currently, the use of IVT in patients with recent direct oral anticoagulant (DOAC) intake is not recommended. In this study we aim to investigate the safety and efficacy of IVT in patients with acute ischemic stroke and recent DOAC use. METHODS AND RESULTS A systematic review and meta-analysis of proportions evaluating IVT with recent DOAC use was conducted. Outcomes included symptomatic intracranial hemorrhage, any intracranial hemorrhage, serious systemic bleeding, and 90-day functional independence (modified Rankin scale score 0-2). Additionally, rates were compared between patients receiving IVT using DOAC and non-DOAC by a random effect meta-analysis to calculate pooled odds ratios (OR) for each outcome. Finally, sensitivity analysis for idarucizumab, National Institutes of Health Stroke Scale, and timing of DOAC administration was completed. Fourteen studies with 247 079 patients were included (3610 in DOAC and 243 469 in non-DOAC). The rates of IVT complications in the DOAC group were 3% (95% CI, 3-4) symptomatic intracranial hemorrhage, 12% (95% CI, 7-19) any ICH, and 0.7% (95%CI, 0-1) serious systemic bleeding, and 90-day functional independence was achieved in 57% (95% CI, 43-70). The rates of symptomatic intracranial hemorrhage (3.4 versus 3.5%; OR, 0.95 [95% CI, 0.67-1.36]), any intracranial hemorrhage (17.7 versus 17.3%; OR, 1.23 [95% CI, 0.61-2.48]), serious systemic bleeding (0.7 versus 0.6%; OR, 1.27 [95% CI, 0.79-2.02]), and 90-day modified Rankin scale score 0-2 (46.4 versus 56.8%; OR, 1.21 [95% CI, 0.400-3.67]) did not differ between DOAC and non-DOAC groups. There was no difference in symptomatic intracranial hemorrhage rate based on idarucizumab administration. CONCLUSIONS Patients with acute ischemic stroke treated with IVT in recent DOAC versus non-DOAC use have similar rates of hemorrhagic complications and functional independence. Further prospective randomized trials are warranted.

Abstract
OBJECTIVE To investigate the safety and effectiveness of direct oral anticoagulants (DOAC) versus vitamin K antagonists (VKA) after recent stroke in patients with atrial fibrillation (AF) aged ≥85 years. METHODS Individual patient data analysis from seven prospective stroke cohorts. We compared DOAC versus VKA treatment among patients with AF and recent stroke (<3 months) aged ≥85 versus <85 years. Primary outcome was the composite of recurrent stroke, intracranial hemorrhage (ICH) and all-cause death. We used simple, adjusted, and weighted Cox regression to account for confounders. We calculated the net benefit of DOAC versus VKA by balancing stroke reduction against the weighted ICH risk. RESULTS In total, 5,984 of 6,267 (95.5%) patients were eligible for analysis. Of those, 1,380 (23%) were aged ≥85 years and 3,688 (62%) received a DOAC. During 6,874 patient-years follow-up, the impact of anticoagulant type (DOAC versus VKA) on the hazard for the composite outcome did not differ between patients aged ≥85 (HR≥85y = 0.65, 95%-CI [0.52, 0.81]) and < 85 years (HR<85y = 0.79, 95%-CI [0.66, 0.95]) in simple (pinteraction = 0.129), adjusted (pinteraction = 0.094) or weighted (pinteraction = 0.512) models. Analyses on recurrent stroke, ICH and death separately were consistent with the primary analysis, as were sensitivity analyses using age dichotomized at 90 years and as a continuous variable. DOAC had a similar net clinical benefit in patients aged ≥85 (+1.73 to +2.66) and < 85 years (+1.90 to +3.36 events/100 patient-years for ICH-weights 1.5 to 3.1). INTERPRETATION The favorable profile of DOAC over VKA in patients with AF and recent stroke was maintained in the oldest old. ANN NEUROL 2021.

Abstract
Although the severity of acute cerebral infarction varies in patients receiving direct oral anticoagulants (DOACs), no practical method to predict the severity has been established. We analyzed retrospectively the relationship between cardioembolic cerebral infarction severity and coagulation indicators in patients treated with DOACs. We assessed the anticoagulation effect of DOACs using the activated partial thromboplastin time (APTT), prothrombin time (PT), and prothrombin time international standardized ratio (PT-INR) in 71 patients with cardioembolic cerebral infarction admitted to our hospital between January 2015 and December 2019. The participants were divided into a prolongation group (prolonged APTT for oral thrombin inhibitors or prolonged PT for oral factor Xa inhibitors, n =37) and a normal group (no prolongation of coagulation markers, n =34). Of the 71 patients, 21 (30%) and 50 (70%) were using oral thrombin and oral factor Xa inhibitors, respectively. PT, PT-INR, and APTT were significantly higher in the prolongation group (PT: 17.4 ± 5.1 vs. 12.8 ± 1.4 s, P < 0.001; PT-INR: 1.5 ± 0.5 vs. 1.1 ± 0.1, P < 0.001; APTT: 44.8 ± 26.4 vs. 30.4 ± 4.1 s, P = 0.003). The median National Institutes of Health Stroke Scale (NIHSS) score on admission and the prevalence of large vessel occlusion were significantly lower in the prolongation group (NIHSS: 2.0 vs. 9.5, P = 0.007; large vessel occlusion: 27% vs. 53%, P = 0.031). The prevalence of large vessel occlusion was low and stroke severity was mild in patients undergoing DOAC therapy with prolongation of coagulation assay markers upon onset of cardioembolic cerebral infarction.

Abstract
PURPOSE OF REVIEW Direct oral anticoagulants (DOAC) are crucial for the prevention of thromboembolic events in patients with nonvalvular atrial fibrillation. Drug adherence by the patient but also adherence to guidelines by the physician are suboptimal. This review highlights aspects of DOAC treatment during the coronavirus disease 2019 (COVID-19) pandemic and selected challenging scenarios. RECENT FINDINGS For patients with a newly diagnosed indication for oral anticoagulation, a new interim clinical guidance recommends starting DOAC instead of vitamin K antagonists if DOAC are not contraindicated. The goal is to reduce the potential exposure of patients to severe acute respiratory syndrome coronavirus during the routine coagulation monitoring visits. As COVID-19 can lead to kidney failure, we discuss the challenges of DOAC dosing in kidney failures. Finally, we discuss two common challenges - when to start a DOAC after an ischemic stroke linked to atrial fibrillation, and whether cerebral microbleeds, including their count, are per se a contraindication to DOAC. SUMMARY There are still open challenges regarding DOAC treatment on the patient and physician side, both related and unrelated to the pandemic.

Abstract
OBJECTIVE The aim was to evaluate, in patients with atrial fibrillation (AF) and acute ischemic stroke, the association of prior anticoagulation with vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs) with stroke severity, utilization of intravenous thrombolysis (IVT), safety of IVT, and 3-month outcomes. METHODS This was a cohort study of consecutive patients (2014-2019) on anticoagulation versus those without (controls) with regard to stroke severity, rates of IVT/mechanical thrombectomy, symptomatic intracranial hemorrhage (sICH), and favorable outcome (modified Rankin Scale score 0-2) at 3 months. RESULTS Of 8,179 patients (mean [SD] age, 79.8 [9.6] years; 49% women), 1,486 (18%) were on VKA treatment, 1,634 (20%) on DOAC treatment at stroke onset, and 5,059 controls. Stroke severity was lower in patients on DOACs (median National Institutes of Health Stroke Scale 4, [interquartile range 2-11]) compared with VKA (6, [2-14]) and controls (7, [3-15], p < 0.001; quantile regression: β -2.1, 95% confidence interval [CI] -2.6 to -1.7). The IVT rate in potentially eligible patients was significantly lower in patients on VKA (156 of 247 [63%]; adjusted odds ratio [aOR] 0.67; 95% CI 0.50-0.90) and particularly in patients on DOACs (69 of 464 [15%]; aOR 0.06; 95% CI 0.05-0.08) compared with controls (1,544 of 2,504 [74%]). sICH after IVT occurred in 3.6% (2.6-4.7%) of controls, 9 of 195 (4.6%; 1.9-9.2%; aOR 0.93; 95% CI 0.46-1.90) patients on VKA and 2 of 65 (3.1%; 0.4-10.8%, aOR 0.56; 95% CI 0.28-1.12) of those on DOACs. After adjustments for prognostic confounders, DOAC pretreatment was associated with a favorable 3-month outcome (aOR 1.24; 1.01-1.51). INTERPRETATION Prior DOAC therapy in patients with AF was associated with decreased admission stroke severity at onset and a remarkably low rate of IVT. Overall, patients on DOAC might have better functional outcome at 3 months. Further research is needed to overcome potential restrictions for IVT in patients taking DOACs. ANN NEUROL 2021;89:42-53.

Abstract
Clinical and imaging characteristics of patients receiving direct oral anticoagulants presenting with transient ischaemic attack or stroke are lacking. A retrospective review of all patients who presented to a high-volume primary stroke centre with acute stroke symptoms while prescribed an oral anticoagulant between January 2012 and June 2017. Clinical, radiological characteristics and functional outcomes were examined. Anticoagulated patients diagnosed with stroke or transient ischaemic attack shared similar disease and outcome characteristics irrespective of anticoagulants used. One-third of warfarin patients with sub-therapeutic international normalised ratios were treated with thrombolytics but no direct oral anticoagulants level was performed in any of the patients, with only one treated by intravenous thrombolysis.

Abstract
Objective We compared outcomes after treatment with direct oral anticoagulants (DOACs) and vitamin K antagonists (VKAs) in patients with atrial fibrillation (AF) and a recent cerebral ischemia. Methods We conducted an individual patient data analysis of seven prospective cohort studies. We included patients with AF and a recent cerebral ischemia (<3 months before starting oral anticoagulation) and a minimum follow‐up of 3 months. We analyzed the association between type of anticoagulation (DOAC versus VKA) with the composite primary endpoint (recurrent ischemic stroke [AIS], intracerebral hemorrhage [ICH], or mortality) using mixed‐effects Cox proportional hazards regression models; we calculated adjusted hazard ratios (HRs) with 95% confidence intervals (95% CIs). Results We included 4,912 patients (median age, 78 years [interquartile range {IQR}, 71–84]; 2,331 [47.5%] women; median National Institute of Health Stroke Severity Scale at onset, 5 [IQR, 2–12]); 2,256 (45.9%) patients received VKAs and 2,656 (54.1%) DOACs. Median time from index event to starting oral anticoagulation was 5 days (IQR, 2–14) for VKAs and 5 days (IQR, 2–11) for DOACs (p = 0.53). There were 262 acute ischemic strokes (AISs; 4.4%/year), 71 intracranial hemorrrhages (ICHs; 1.2%/year), and 439 deaths (7.4%/year) during the total follow‐up of 5,970 patient‐years. Compared to VKAs, DOAC treatment was associated with reduced risks of the composite endpoint (HR, 0.82; 95% CI, 0.67–1.00; p = 0.05) and ICH (HR, 0.42; 95% CI, 0.24–0.71; p < 0.01); we found no differences for the risk of recurrent AIS (HR, 0.91; 95% CI, 0.70–1.19; p = 0.5) and mortality (HR, 0.83; 95% CI, 0.68–1.03; p = 0.09). Interpretation DOAC treatment commenced early after recent cerebral ischemia related to AF was associated with reduced risk of poor clinical outcomes compared to VKA, mainly attributed to lower risks of ICH.

Clinical presentation, diagnostic findings and management of cerebral ischemic events in patients on treatment with non-vitamin K antagonist oral anticoagulants - A systematic review. PLoS One 2019; 14:e0213379. [PMID: 30925155 PMCID: PMC6440627 DOI: 10.1371/journal.pone.0213379] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2018] [Accepted: 02/19/2019] [Indexed: 12/28/2022] Open
Abstract
Background Non-vitamin K antagonist oral anticoagulants (NOAC) are equally or potentially superior in terms of effectiveness in the prevention of ischemic stroke and carry a lower associated risk of intracranial hemorrhage compared to Vitamin K antagonists. Nevertheless, ischemic strokes also occur in patients who are being treated with NOAC. In those particular patients, knowledge about the underlying stroke etiology, clinical presentation, acute management, and complication rates is scarce. Objective Systematic literature review to provide a comprehensive clinical overview in terms of presentation, laboratory, imaging parameters and outcomes of patients suffering from acute cerebral ischemic events (i.e. TIA and acute ischemic stroke) while on treatment with a NOAC. Only if available, comparison to VKA is presented which was not the primary focus of this analysis. Data sources PubMed/MEDLINE, Scopus and EMBASE from January 1, 2006, to November 20, 2018. Study eligibility criteria 52 studies providing detailed information on a total of 12247 patients were included. We excluded case reports and case series with less than five patients. Study appraisal and synthesis method We systematically assessed study quality using a bias tool and pooled consistent data. Results Existing data indicates milder stroke severity and smaller infarct size of acute ischemic stroke on treatment with NOAC compared to stroke occurrence on Vitamin K antagonists (VKA). Established risk factors for ischemic events also play a role in stroke while on NOACs, albeit the underlying etiology remains poorly understood. Intravenous thrombolysis and endovascular therapy seem to be safe and effective, but patient selection for recanalization therapies is challenging. Limitations Limited quality of published data, duplicate cases, statistical issues of data pooling, possible incomplete retrieval of identified research and reporting bias might have limited our findings. Conclusions Acute ischemic events despite treatment with NOAC therapy are insufficiently investigated. Systematic review registration number PROSPERO: CRD42018074853.
