Abstract Background The optimal timing for starting anticoagulation after an acute ischemic stroke related to non-valvular atrial fibrillation (AF) remains a challenge, especially in patients treated with systemic thrombolysis or mechanical thrombectomy. Purpose We aimed to assess the rates of early recurrence and major bleeding in patients with acute ischemic stroke and AF treated with thrombolytic therapy and/or thrombectomy who received oral anticoagulants for secondary prevention. Methods We combined the dataset of the RAF and the RAF-NOACs studies, which were prospective observational studies carried out from January 2012 to March 2014 and April 2014 to June 2016, respectively. We included consecutive patients with acute ischemic stroke and AF treated with either vitamin K antagonists (VKAs) or new oral anticoagulants (NOACs). Primary outcome was the composite of stroke, transient ischemic attack, symptomatic systemic embolism, symptomatic cerebral bleeding, and major extracerebral bleeding within 90 days from the inclusion. Results A total of 2,159 patients were included in the RAF and RAF-NOACs trials, of which 564 patients (26%) were treated with urgent reperfusion therapy. After acute stroke, 505 (90%) patients treated with reperfusion and 1,287 out of the 1,595 (81%) patients not treated with reperfusion started oral anticoagulation. Timing of starting oral anticoagulation was similar in reperfusion-treated and untreated patients (13.5±23.3 vs 12.3±18.3 days, respectively, p=0.287). At 90 days, the composite rate of recurrence and major bleeding occurred in 37 (7%) of patients treated with reperfusion treatment and in 139 (9%) of untreated patients (p=0.127). Twenty-four (4%) reperfusion-treated patients and 82 (5%) untreated patients had early recurrence while major bleeding occurred in 13 (2%) treated and in 64 (4%) untreated patients, respectively. Seven patients in the untreated group experienced both an ischemic and hemorrhagic event. Figure 1 shows the risk of early recurrence and major bleeding over time in patients treated and not treated with reperfusion treatments. The use of NOACs was associated with a favorable rate of the primary outcome compared to VKAs (Odd ratio 0.4, 95% Confidence Interval 0.3–0.7). Conclusions Reperfusion treatment did not influence the risk of early recurrence and major bleeding in patients with AF-related acute ischemic stroke who started anticoagulant treatment.

Introduction: Atrial fibrillation (AF) and large artery diseases (LAD) share several risk factors and often coexist in the same patient. Optimal treatments for acute ischemic stroke (AIS) patients with concomitant AF and LAD have not been extensively studied so far. Objective: This study aimed to compare the effectiveness of the addition of antiplatelet (AP) to oral anticoagulant (OAC) with that of OAC alone in AIS with AF according to the LAD. Methods: Using a multicenter stroke registry, acute (within 48h of onset) and mild-to-moderate (NIHSS score ≤15) stroke patients with AF were identified. Propensity scores using IPTW were used to adjust baseline imbalances between the OAC+AP group and the OAC alone group in all patients and in each subgroup by LAD. The primary outcome was major vascular events, defined as the composite of recurrent stroke, MI, and all-cause mortality at up to 3 months after index stroke. Results: Among the 5469 patients (age, 72±10yrs; male, 54.9%; initial NIHSS score, 4 [2-9]), 79.0% (n=4323) received OAC alone, and 21.0% (n=1146) received OAC+AP. By weighted Cox proportional hazards analysis, a tendency of increasing the risk of 3-months primary composite events in the OAC+AP group vs the OAC alone (HR 1.36 [0.99-1.87], p=0.06), with significant interaction with treatments and LAD (Pint=0.048). Briefly, among patients with moderate-to-severe large artery stenosis, tendency of decrease in 3-months primary composite events of the OAC+AP group, compared with OAC alone group, was observed (HR 0.54 [0.17-1.70]), whereas among patients with complete occlusion, the OAC+AP group markedly increased the risk of 3-months composite events (HR 2.00 [1.27-3.15]), compared with the OAC alone group. No interaction between direct oral anticoagulant and warfarin on outcome was observed (Pint=0.35). Conclusion: In conclusion, treatment with addition of AP to OAC had a tendency to increase the risk of 3-months vascular events, compared with OAC alone in AIS with AF. However, the effects of antithrombotic treatment could be modified according to the LAD, with substantial benefits of OAC alone in subgroup of large artery occlusion. Our results address the need for the further study to tailor the optimal treatment in AIS with concomitant AF and LAD.

Long Term Mortality

Background: Cerebral microbleeds (CMBs) were predictive of mortality in elderly and considered as a putative marker for risk of intracranial hemorrhage. Stroke patients with non valvular atrial fibrillation (NVAF) require anticoagulation, which increases the risk of hemorrhages. We investigated association of CMBs with the long term mortality in acute ischemic stroke patients with NVAF. Methods: During 6 years , consecutive ischemic stroke patients who had NVAF and who had undergone brain MRI with a gradient-recalled echo sequence were enrolled. Long-term mortality and causes of death were identified using data from Korean National Statistical Office. Survival analysis was performed whether the presence, number and location of CMBs were related with all causes, cardiovascular, and cerebrovascular mortality during follow-up. Results: Total 506 patients were enrolled during the study period and were followed up for median 2.5 years. CMBs were found in 30.8% of patients (156/506). Oral anticoagulation with warfarin was prescribed at discharge in 477 (82.7%) patients. During follow up, 177 (35%) patients died and cerebrovascular death was noted in 93 patients (81 ischemic stroke and 12 hemorrhagic stroke). After adjusting age, sex and significant variables in univariate analysis (p<0.1), multiple CMBs (≥5) were the independent predictor for all-cause, cardiovascular and ischemic stroke mortalities. The strictly lobar CMBs were associated with hemorrhagic stroke mortality in multivariate Cox regression analysis (HR 4.776, p=0.032) (Figure 1). Conclusions: Multiple CMBs were the independent predictor for the long term mortality in stroke patients with NVAF. Among them, patients with strictly lobar CMBs had a high risk of death due to hemorrhagic stroke. Our findings suggest that detection of CMBs in stroke patients with NVAF are of clinical relevance for predicting long term outcome and that particular concern is necessary in those with strictly lobar CMBs for their increased risk of death due to hemorrhagic stroke.

Background: Mobile Cardiac outpatient telemetry (MCOT) is often used for patients (pts) with cryptogenic ischemic stroke following hospital discharge to detect atrial fibrillation (AFib) but criteria for patient selection remains a subject of debate. Methods: We identified 297 pts hospitalized with acute ischemic stroke who had an inpatient transthoracic echocardiogram (TTE) and underwent MCOT upon discharge between 2016 and 2018 at a large academic comprehensive stroke center. Pts characteristics between AFib vs. no AFib were compared by Fisher’s exact test for categorical and Wilcoxon rank-sum test for continuous variables. A multivariable stepwise logistic regression model was developed to determine the predictors of AFib detection. Statistical hypotheses were tested as two-sided at 0.05 level of significance. Results: Of the 297 pts, AFib was detected in 24 (8.1%) on 30-day MCOT. Pts with AFib detected were older, white, and have had a larger left atrial area (Table). The final logistic model demonstrated that white race (vs. non-white) (OR 4.86, 1.53-15.41), left atrial area (OR 1.15, 1.05-1.25) and left ventricular internal diameter in diastole (OR 0.33, 0.16-0.67) were associated with AFib detection by MCOT. Conclusion: Although rates of AFib detection on 30-day MCOT post-discharge was low, there are important patient characteristics and TTE features that can improve patient selection. Further studies are needed to determine if this data can be used prospectively to clinically decide which pts with cryptogenic stroke should be given 30-day MCT to detect atrial fibrillation.

Introduction : Previous research into the administration of rTPA therapy in acute ischemic stroke patients has largely focused on the general population, however the comorbid clinical factors held by stroke patients are important factors in clinical decision making. One such comorbid condition is Atrial Fibrillation. The purpose of this study is to determine the clinical factors associated with the administration of rtPA in Acute Ischemic Stroke (AIS) patients specifically with a past medical history of Atrial Fibrillation (AFib). Methods : The data for this analysis was collected at a regional stroke center from January 2010 to June 2016 in Greenville, SC. It was then analyzed retrospectively using a multivariate logistic regression to identify factors significantly associated with the inclusion or exclusion receiving rtPA therapy in the AIS/AFib patient population. This inclusion or exclusion is presented as an Odds Ratio and all data was analyzed using IBM SPSS. Results : A total of 158 patients with Atrial Fibrillation who had Acute Ischemic Strokes were identified. For the 158 patients, the clinical factors associated with receiving rtPA therapy were a Previous TIA event (OR = 12.155, 95% CI, 1.125‐131.294, P < 0.040), the administration of Antihypertensive medication before admission (OR = 7.157, 95% CI, 1.071‐47.837, P < 0.042), the administration of Diabetic medication before admission (OR = 13.058, 95% CI, 2.004‐85.105, P < 0.007), and serum LDL level (OR = 1.023, 95% CI, 1.004‐1.042, P < 0.16). Factors associated with not receiving rtPA therapy included a past medical history of Depression (OR = 0.012, 95% CI, 0.000‐0.401, P < 0.013) or Obesity (OR = 0.131, 95% CI, 0.034‐0.507, P < 0.003), Direct Admission to the Neurology Floor (OR = 0.179, 95% CI, 0.050‐0.639, P < 0.008), serum Lipid level (OR = 0.544, 95% CI, 0.381‐0.984, P < 0.044), and Diastolic Blood Pressure (OR = 0.896, 95% CI, 0.848‐0.946, P < 0.001). Conclusions : The results of this study demonstrate that there are significant associations between several clinical risk factors, patient lab values, and hospital admission factors in the administration of rTPA therapy to AIS patients with a past medical history of Atrial Fibrillation. Further research is recommended to determine the extent and reasoning behind of these associations as well as their impact on the clinical course for AIS/AFib patients.
