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.

Background and Purpose: Cerebral microbleeds (CMBs) are now considered to be one of the neuroimaging markers of cerebral small vessel disease. It has been reported that CMBs are associated with age, hypertension, cognitive impairment, and use of antithrombotic drugs. We aimed at identifying factors associated with the presence of CMBs among acute ischemic stroke patients with non-valvular atrial fibrillation (NVAF) who participated in the multicenter Stroke Acute Management with Urgent Risk-factor Assessment and Improvement (SAMURAI)-NVAF study. Methods: Acute ischemic stroke/transient ischemic attack (within 7 days of onset) patients with NVAF who underwent T2*-weighted images on magnetic resonance imagings at baseline were included in the analysis. Factors associated with the presence of CMBs were assessed in univariable and multivariable logistic regression models. Results: Of 1,099 (77.6±10.0 years, 620 male) participants, 256 (23.2%) had CMBs: single CMB in 96 (8.7%), 2-4 of CMBs in 109 (9.9%), and ≥5 CMBs in 51 (4.6%). The presence of CMBs was associated with age [per 10 years, odds ratio (OR) 1.21; 95% confidence interval (CI) 1.02-1.44], past history of stroke (OR 1.52; 95% CI 1.09-2.11), and advanced cognitive impairment (OR 1.64; 95% CI 1.02-2.61) in multivariable analysis adjusted for sex, hypertension, arterial disease, ever smoking, premorbid antithrombotic medications, and estimated glomerular filtration rate. Among 514 patients (46.8% of the participants) with the data of urinary albumin, clinical albuminuria (urinary albumin ≥300 mg/gCr) and past history of stroke were identified as independent factors associated with CMBs (OR 1.91; 95% CI 1.06-3.42 and 1.67; 1.04-2.66, respectively). Conclusions: Approximately one fourth of acute ischemic stroke patients with NVAF had CMBs. Past history of stroke and clinical albuminuria were identified as independent determinants of CMBs on top of established ones. Clinical Trial Registration: URL: http://www.clinicaltrials.gov .

Introduction: Electrocardiogram (ECG) findings of premature atrial contraction and prolonged PR interval are associated with risk of onset atrial fibrillation (AF) in cryptogenic stroke. We sought to see if normal ECG and AF incidence is incompletely understood. Methods: From a prospective single-hospital stroke registry from 2018, we identified ischemic stroke patients who had ECG done on admission for review. We excluded patients with AF on admission ECG, history of AF, and implanted device with cardiac monitoring capability. Normal ECG was interpreted based on the standardized reporting guidelines for ECG studies evaluating risk stratification of emergency department patients. Stroke subtype was diagnosed according to the TOAST classification: large artery atherosclerosis (LAA), small vessel occlusion (SVO), cardioembolism, others/undetermined and embolic stoke of undetermined source (ESUS) criteria. We compared the incidence of newly diagnosed AF during hospitalization and from outpatient cardiac event monitoring between normal and abnormal ECG. Results: Of the 558 consecutive acute ischemic stroke patients, we excluded 135 with AF on admission ECG or history of AF and 9 with implanted devices. Of the remaining 414 patients that were included in the study, ESUS (31.2%) was the most frequent stroke subtype, followed by LAA (30.0%), SVO (14.0%), others/undetermined (15.7%), and cardioembolism (9.2%). Normal ECG was observed in 125 patients (30.2%). Cardioembolic subtype was less frequent in the normal versus abnormal ECG group (1.6% vs. 12.5%, p<0.001). New AF was detected in 17/414 patients (4.1%) during hospitalization. Of these 17 patients, none had normal ECG (0/125) and all had abnormal ECG (17/289, 5.9%) (p=0.002). After discharge, of 111 patients undergoing 4-week outpatient cardiac monitoring, new AF was detected in 16 (14.4%). Of these 16 patients, only 1 had a normal ECG (1/35, 2.9%) while 15 had abnormal ECG (15/76, 19.7%) (p=0.02). Conclusions: Normal ECG at admission for acute ischemic stroke is associated with low likelihood of detection of new atrial fibrillation in either the inpatient or outpatient setting.

Introduction: Paroxysmal atrial fibrillation (PAF) is an important risk factor for ischemic stroke and has similar risk to permanent atrial fibrillation (AF), but detecting PAF is challenging. Holter ECG has a low sensitivity. Continuous ECG monitoring and implanted event recorders are high cost and inconvenient for elderly patients. Identifying patients at a particularly high risk of PAF by using scores may represent a reasonable alternative. We aimed to elucidate a clinical profile of patients with PAF including those risk factors by multiple variable analysis and create a score to detect patients with PAF. Methods: Consecutive patients with acute ischemic strokes from 2010 to 2011 were prospectively analyzed. We excluded patients with permanent AF. All patients without permanent AF had 24-hour Holter ECG and ECG monitoring on the ward within 7 days. Collected data included demographic data, clinical data including history of irregular rhythm or antiarrhythmic agent and transthoracic echocardiography data. PAF was documented by review of medical history, baseline ECG, ECG monitoring and Holter ECG. Results: We studied 197 stroke patients and excluded 45 (23%) patients with permanent AF. Thirty-five (23%) of 152 patients had PAF. Univariate analyses revealed that older age (p = 0.008), arrhythmia history (p <0.0001), higher brain natriuretic peptide (BNP) (p <0.0001) and left atrial dilatation (p = 0.007) were significantly associated with documented PAF more than without documented AF. Arrhythmia history (OR 11.4, 95% CI 2.4-54.0), BNP ≥ 85 pg/ml (OR 24.2, 95% CI 6.8-86.1) and left atraial (LA) diameter ≥ 40 mm (OR 3.3, 95% CI 1.1-9.5) were significantly independent predictive factors of PAF by logistic regression analysis. We calculated a score (BNP [≥ 150 pg/ml:3 point, 149-85 pg/ml:2], arrhythmia history[yes:2] and dilatation of LA [≥ 40 mm:1]. The area under the ROC curve for the documented PAF group was 0.908 and a total score ≥ 3 had a sensitivity of 83% and a specificity of 87%. Conclusions: In acute ischemic stroke patients without permanent AF, patients with documented PAF had significantly more history of arrhythmia, higher BNP and LA dilatation than those without documented AF. The new score can be useful to identify individuals at high risk of PAF.

Abstract Background Specific clinical risk factors may contribute to worsening or improving neurological functions in an acute ischemic stroke (AIS) patient pre-treated with a cholesterol reducer with a subsequent recombinant tissue plasminogen activator (rtPA) treatment. We investigated clinical risk factors associated with good or poor presenting neurological symptoms in ischemic stroke patients with prior cholesterol reducer use, specifically a statin and rtPA therapy. Methods We retrospectively analyzed baseline clinical and demographic data of 630 patients with AIS taking cholesterol reducers prior to rtPA treatment from January 2010 to June 2016 in a regional stroke center. Progressing (NIHSS ≤ 7) or worsening (NIHSS > 7) scores for neurologic improvement determined measures for treatment outcome. Multivariate logistic regression models identified demographic and clinical factors associated with worsening or progressing neurologic functions. Results Adjusted multivariate analysis showed that in an ischemic stroke population with a combined rtPA and cholesterol reducer medication history, increasing age (OR = 1.032, 95% CI, 1.015-1.048, P < 0.001) and atrial fibrillation (OR = 1.859, 95% CI, 1.098-3.149, P = 0.021) demonstrated a likely association with worsening neurologic functions, while direct admission (OR = 0.411, 95% CI, 0.246-0.686, P = 0.001) and being Caucasian (OR = 0.496, 95% CI, 0.297-0.827, P = 0.007) showed an association with improving or progressing neurologic functions. Conclusion A prior cholesterol reducer, namely a statin, plus rtPA combination may be associated with worsening neurological function for elderly AIS patients with atrial fibrillation, while Caucasians directly admitted to a neurology unit are more likely to show an association with progress or improvements in neurologic functions.

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.
