Abstract Background: Deep vein thrombosis (DVT) is an important complication of ischemic stroke, although the incidence of DVT is regarded as being lower in Asian than in non-Asian patients. Here, we investigated the incidence and factors associated with DVT in Asian patients with ischemic stroke.Methods: Acute ischemic stroke patients received lower extremity ultrasonography (LEUS) to diagnose the presence of DVT. Clinical characteristics and laboratory results, including D-dimer level, were compared between patients with and without DVT. Independent risk factors for DVT were investigated using multivariable analysis. Similar analysis was performed to identify factors associated with elevated D-dimer level (>0.5 mg/dl) in acute ischemic stroke patients.Results: During the study period, 289 patients were enrolled, and 38 (13.1%) showed DVT. Female sex (OR=2.579, 95% CI=1.224–5.432; p=0.013) and a high National Institutes of Health Stroke Scale (NIHSS) score (OR=1.191 95% CI=1.095–1.294; p=0.005) were independently associated with the presence of DVT, although D-dimer level was not. Stroke mechanism, especially cardioembolic stroke (OR=3.777, 95% CI=1.532–9.313; p=0.004; reference: large artery atherosclerosis), NIHSS score (OR=1.087, 95% CI=1.002–1.179; p=0.001) and thrombolysis (OR=12.360, 95% CI 2.456-62.213; p=0.002) were independently associated with elevated abnormal D-dimer levels.Conclusion: The severity of ischemic stroke, but not the D-dimer level, was associated with the presence of DVT in Asian ischemic stroke patients. D-dimer level was influenced by the stroke mechanism. LEUS in patients with severe neurological deficit, rather than screening with D-dimer, may be more beneficial for diagnosing DVT in Asian patients with acute ischemic stroke.

Background: Stroke in cancer patients is not rare, but is a devastating event with high mortality. However, the predictors of mortality in stroke patients with cancer have not been well addressed. D-dimer could be a useful predictor because it can reflect both thromboembolic events and advanced stages of cancer. In this study, we evaluate the possibility of D-dimer as a predictor of 30-day mortality in stroke patients with active cancer. Methods: We included 210 ischemic stroke patients with active cancer. The data of 30-day mortality were collected by reviewing medical records. We also collected follow-up D-dimer levels in 106 (50%) participants to evaluate the effects of treatment response on D-dimer levels. Results: Of the 210 participants, 30-day mortality occurred in 28 (13%) patients. Higher initial NIHSS score, D-dimer levels, CRP levels, frequent cryptogenic mechanism, systemic metastasis, multiple vascular territory lesion, hemorrhagic transformation, and larger infarct volume were related to 30-day mortality. In the multivariate analysis, D-dimer [adjusted OR (aOR) = 2.19; 95% CI, 1.46-3.28, P < 0.001] predicted 30-day mortality after adjusting for confounders. Initial NIHSS score (aOR = 1.07; 95% CI, 1.00-1.14, P = 0.043) and hemorrhagic transformation (aOR = 3.02; 95% CI, 1.10-8.29, P = 0.032) were also significant independently from D-dimer levels. In the analysis of D-dimer changes after treatment, the mortality group showed no significant decrease of D-dimer levels, despite treatment, while the survivor group showed opposite responses. Conclusions: D-dimer levels may predict 30-day mortality in acute ischemic stroke patients with active cancer.

Background and Purpose: We aimed to investigate the differences in weekly variations of stroke occurrence between hyper-acute ischemic stroke patients with and without regular employments (RE), and the impact of RE on outcome. Methods: Consecutive symptomatic ischemic stroke patients with < 4.5 h from onset to door between October 2012 and May 2018 were enrolled. All the situations of employment on admission were obtained from interviews with the participant or substitute guardians. First, we divided the patients into with and without RE to evaluate the differences in weekly variations of stroke occurrence. Second, we divided the same patients into with and without favorable outcome (mRS score of 0 to 2 at 3 months from the onset) to evaluate the impact of RE on outcome. Results: We screened 1,249 consecutive symptomatic ischemic stroke patients, including 385 patients (292 (76%) male, median age 67 years) with hyper-acute ischemic stroke. Of all, 251 patients (65%) were included in RE group. In the multivariate analysis, patients with RE were more likely to develop strokes on Monday compared to that on Sunday and public holiday (OR 2.841, 95% CI 1.145-7,049, p = 0.024, Figure A). In the multivariate analysis, the factors associated with favorable outcome were low NIHSS score on admission (OR 0.909, 95% CI 0.857-0.964, p = 0.001), not receiving endovascular therapy (OR 0.175 95% CI 0.069-0.444, p <0.001), and having RE (OR 2.506, 95% CI 1.049-5.986, p = 0.039, Figure B). Conclusions: There were dramatic differences in weekly variations of hyper-acute ischemic stroke occurrence between patients with and without RE. Monday seems to be “a black day” for ischemic stroke patients with RE. RE had a positive impact on outcome in hyper-acute ischemic stroke.

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: Recent trials have demonstrated a reduction in death or disability with endovascular treatment in patients with acute ischemic strokes. However, readmission rates and predictors are not known. Objective: To identify rates and factors associated with 30-day readmission after endovascular treatment in ischemic stroke patients. Methods: Nationwide Readmissions Data (NRD) between 2010 and 2017 was utilized to identify endovascular treatment in acute ischemic stroke patients using ICD-9 and ICD-10 codes. We used hierarchical logistic regression model to identify factors associated with 30-day readmissions. Results: Among 17, 562 acute ischemic stroke patients who survived to discharge after endovascular treatment, 2334 (13.29%) were readmitted within 30-days. Age => 65 years (odds ratio [OR]: 1.23, 95% confidence interval [CI]: 1.09 to 1.39, p =0.0005), chronic kidney disease (OR: 1.28, 95%CI: 1.12 to 1.47, p = 0.0004), congestive heart failure (OR: 1.25, 95%CI: 1.13 to 1.39, p <.0001), post procedure intracranial hemorrhage (OR: 1.09, 95%CI: 0.99 to 1.20, p = 0.04) and diabetes mellitus (OR: 1.09, 95%CI: 0.99 to 1.20, p = .09) during the index hospitalization were associated with readmission within 30 days. Conclusion: In this large nationally representative study, nearly one in 10 patients were readmitted within 30 days after discharge in acute ischemic stroke patients undergoing endovascular treatment. Medical comorbidities and post procedure intracranial hemorrhage were associated with 30-day readmission.

Background: This study assessed the incidence and predictors of short-term stroke recurrence in ischemic stroke patients with active cancer, and elucidated whether cancer-associated hypercoagulation is related to early recurrent stroke. Methods: We retrospectively enrolled acute ischemic stroke patients with active cancer admitted to our hospital between 2006 and 2017. Active cancer was defined as diagnosis or treatment for any cancer within 12 months before stroke onset, known recurrent cancer or metastatic disease. The primary clinical outcome was recurrent ischemic stroke within 30 days. Results: One hundred ten acute ischemic stroke patients with active cancer (73 men, age 71.3 ± 10.1 years) were enrolled. Of those, recurrent stroke occurred in 12 patients (11%). When patients with and without recurrent stroke were compared, it was found that those with recurrent stroke had a higher incidence of pancreatic cancer (33 vs. 10%), systemic metastasis (75 vs. 39%), multiple vascular territory infarctions (MVTI; 83 vs. 40%), and higher ­D-dimer levels (16.9 vs. 2.9 µg/mL). Multivariable logistic regression analysis showed that each factor mentioned above was not significantly associated with stroke recurrence independently, but high D-dimer (hDD) levels (≥10.4 µg/mL) and MVTI together were significantly associated with stroke recurrence (OR 6.20, 95% CI 1.42–30.7, p = 0.015). Conclusions: Ischemic stroke patients with active cancer faced a high risk of early recurrent stroke. The concurrence of hDD levels (≥10.4 µg/mL) and MVTI was an independent predictor of early recurrent stroke in active cancer patients. Our findings suggest that cancer-associated hypercoagulation increases the early recurrent stroke risk.
