Background: Establishing aphasia prevalence and outcome after ischemic stroke can facilitate strategies for treatment of aphasia. Few studies of aphasia recovery after ischemic stroke have included consecutive, unselected patients. Our aim was to identify acute and chronic prevalence of aphasia in an unselected consecutive cohort of patients with ischemic stroke. Methods: 218 patients with first-ever acute ischemic stroke were included prospectively and consecutively in the Lund Stroke Register Study. Patients with 1) dementia or psychiatric disorders; 2) non-native Swedish language; or 3) decreased consciousness were not included. Language assessment was made at baseline (within 6 days, median 3 days) after stroke onset by trained research nurses using the NIHSS sub-item 9, “Best Language” to screen for aphasia. Patients with aphasia (score of 1-3 on NIHSS item 9) were re-assessed with NIHSS item 9 by speech and language pathologists at 1 month, 3 months and 12 months after stroke. Results: Of 218 first-ever ischemic stroke patients 52 patients (24%) had aphasia according to NIHSS item 9 (median age 75 years; n=25 female). The distribution of the scores 1-3 at baseline were n=32, n=11, and n=9, respectively. At the 1 year follow-up, 31 patients (67%; n=5 deceased, n=1 drop out) had recovered from aphasia (n=28 with initial NIHSS item 9 score of 1, n=2 with initial NIHSS item 9 score of 2), even though all patients with initial global aphasia (NIHSS item 9 score of 3) had remaining aphasia (NIHSS item 9 score ≥ 1). Figure 1shows aphasia recovery (n=52) according to NIHSS item 9. Conclusions: A majority of patients with mild aphasia recover substantially from aphasia within 1 year after stroke. Patients with initial global aphasia all suffer from remaining aphasia 1 year after stroke. This suggests that this population might especially benefit from an early onset comprehensive, long-term aphasia treatment plan.

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.

New Onset

Introduction: Prolonged P-wave duration (PWD) is associated with paroxysmal atrial fibrillation (AF), which might be underdiagnosed in ischemic stroke patients, in whom it might be pivotal for initiation of secondary prevention oral anticoagulation therapy. We aimed to assess whether PWD predicts new-onset AF during 10-year follow-up in ischemic stroke patients compared to control subjects enrolled in the Lund Stroke Register (LSR). Methods: Study sample comprised of 227 first-ever ischemic stroke patients without AF (mean age 72±12 y, 92 female) and 1:1 age- and gender- matched control subjects without stroke and AF enrolled in LSR from Mar 2001 to Feb 2002. The date of new-onset AF during follow-up was assessed by the date of first AF ECG in the regional ECG database and by record linkage with the Swedish National Patient Register. The available standard snapshot 12-lead sinus rhythm ECGs at baseline were retrieved from electronic database and digitally processed. Results: Patients with ischemic stroke compared to controls more often had hypertension (57% vs 31%), diabetes (15% vs 7%) and vascular diseases (42% vs 13%, all p < 0.005). New-onset AF was detected in 39 (17%) stroke patients and in 30 (13%) controls, p=0.296. In the multivariate Cox regression analysis, new onset AF in the stroke group was associated with age>65 years (HR=3.78, 95%CI 1.32-10.85, p=0.013) and hypertension (HR=2.42, 95%CI 1.09-5.40, p=0.030), but not with PWD. On the contrary, PWD>120 ms was the only independent predictor of new onset AF in the control group after adjustment for age and cardiovascular risk factors (HR=3.36, 95%CI 1.41-8.01, p=0.006, Figure 1). Conclusions: Prolonged P-wave duration is the strongest predictor of AF incidence during 10-year follow-up in stroke-free population. However, in ischemic stroke patients the developing of AF is more likely associated with more advanced cardiovascular comorbidities than with electrical abnormalities in the heart.

Abstract Background We aim to document the long-term outcomes of ischemic stroke patients and explore the potential risk factors for recurrent cardiovascular events and all-cause mortality in primary care. Methods A retrospective cohort study performed at two general out-patient clinics (GOPCs) under Hospital Authority (HA) in Hong Kong (HK). Ischemic stroke patients with at least two consecutive follow-up visits during the recruitment period (1/1–30/6/2010) were included. Patients were followed up regularly till the date of recurrent stroke, cardiovascular event, death or 31/12/2018. The primary outcome was the occurrence of recurrent cerebrovascular event including transient ischemic stroke (TIA), ischemic stroke or hemorrhagic stroke. The secondary outcomes were all-cause mortality and coronary artery disease (CAD). We fit cox proportional hazard model adjusting death as competing risk factor to estimate the cause-specific hazard ratio (csHR). Results A total of 466 patients (mean age, 71.5 years) were included. During a median follow-up period of 8.7 years, 158 patients (33.9%) died. Eighty patients (17.2%) had recurrent stroke and 57 (12.2%) patients developed CAD. Age was an independent risk factor for recurrent stroke, CAD and death. Statin therapy at baseline had a protective effect for recurrent stroke (csHR = 0.476; 95% confidence interval [CI] 0.285–0.796, P = 0.005) after adjusting death as a competing risk factor and all-cause mortality (HR = 0.693, 95% CI 0.486–0.968, P = 0.043). In addition, female sex, antiplatelet and a higher diastolic blood pressure (DBP) at baseline were also independent predictors for survival. Conclusions Long term prognosis of ischemic stroke patients in primary care is favorable. Use of statin was associated with a significant decrease in stroke recurrence and mortality. Patients who died had a significant lower DBP at baseline, highlighted the need to consider both systolic and diastolic blood pressure in our daily practice.

Lacunar stroke (LS) is responsible for one-quarter of the overall number of ischemic strokes with long-term complications and carries health and economic issues for patients and health care systems. Therefore, we aimed to investigate lacunar versus non-lacunar strokes in a tertiary academic center. From February 2016 to July 2019, all patients admitted to the stroke unit were retrospectively reviewed. We included LS patients and compared them to other TOAST subtypes. Hemorrhagic stroke and conditions mimicking stroke were excluded. Regression analysis was done to determine LS predictors and outcomes. A 35.5% rate of LS among 989 ischemic stroke patients was found. Most patients (71.9%) were males. Lower National Institutes of Health Stroke Scale (NIHSS) scores at admission and negative history for cardiac diseases were predictors for LS in our population. At discharge, LS patients had low NIHSS scores and shorter hospitalization periods compared to non-LS patients. In conclusion, LS was prevalent among ischemic stroke patients in our cohort. Future studies are highly needed with long follow-up intervals to identify the stroke recurrence, complications, and outcomes.

Warfarin Treatment

Background: Oral anticoagulation is recommended for ischemic stroke patients with atrial fibrillation, based on clinical trials done in selected populations. However, little is known about whether the clinical benefit of warfarin is preserved outside the clinical trial setting, especially in older patients with ischemic stroke. Methods: PROSPER, a PCORI-funded research program designed by stroke survivors and stakeholders, used American Heart Association Get With The Guidelines (GWTG)-Stroke data linked to Medicare claims to evaluate the association between warfarin treatment at discharge and long-term outcomes among ischemic stroke survivors with atrial fibrillation (AF) and no contraindication to or prior anticoagulation therapy. The primary outcome prioritized by patients was home-time (defined as days spent alive and not in inpatient post-acute care facility) within 2-year follow-up after discharge. Results: Of 12,552 ischemic stroke patients with AF admitted from 2009-2011, 11,039 (88%) received warfarin treatment at discharge. Compared with those not receiving any anticoagulation, warfarin-treated patients were slightly younger (mean 80 vs. 83, p<0.001), less likely to have a history of prior stroke or coronary artery disease, but had similar stroke severity as measured by NIHSS (median 5 [IQR 2-12] vs. 6 [2-13], p=0.09). After adjustment for all observed baseline characteristics using propensity score inverse probability weighting method, patients discharged on warfarin therapy had 45 more days of home-time during 2-year follow-up than those not receiving any oral anticoagulant (513 vs. 468 days, p<0.001). Warfarin use was also associated with a lower risk of all-cause mortality, cardiovascular readmission or death, and ischemic stroke (Table). Conclusions: Among ischemic stroke patients with atrial fibrillation, warfarin therapy was associated with improved long-term outcomes.

Introduction: Diabetes mellitus (DM) is known to influence outcomes in the short-term following stroke. However, the impact of DM on long-term functional outcomes after stroke is unclear. We compared functional outcomes periodically over 7 years between diabetic and non-diabetic ischemic stroke patients and investigated the impact of DM on the long-term trajectory of post-stroke functional outcomes. We also studied the influence of age on the diabetes-functional outcome association. Methods: This is a longitudinal observational cohort study of 802 acute ischemic stroke patients admitted to the Singapore General Hospital from 2005 to 2007. Functional outcomes were assessed using the modified Rankin Scale (mRS) with poor functional outcome defined as mRS≥3. Follow-up data was determined at 6 months and at median follow-up durations of 29 and 86 months. Results: Among the 802 ischemic stroke patients studied (mean age 64 ± 12 years, male 63%), 42% had DM. In regression analyses adjusting for covariates, diabetic patients were more likely to have poor functional outcomes at 6 months (OR=2.12, 95% CI: 1.23–3.67) and at median follow-up durations of 29 months (OR=1.96, 95% CI: 1.37–2.81) and 86 months (OR=2.27, 95% CI: 1.58–3.25). In addition, age modulated the effect of DM, with younger stroke patients (≤65 years) more likely to have long term poor functional outcome at the 29-month (p=0.0179) and 86-month (p=0.0144) time points. Conclusions: DM was associated with poor functional outcomes following ischemic stroke in the long term with the effect remaining consistent throughout the 7-year follow-up period. Age modified the effect of DM in the long term, with an observed increase in risk in the ≤65 age group but not in the >65 age group.

Abstract Background The treatment of acute ischemic stroke is heavily time-dependent, and even though, with the most efficient treatment, the long-term functional outcome is still highly variable. In this current study, the authors selected acute ischemic stroke patients who were qualified for intravenous thrombolysis with recombinant tissue plasminogen activator and followed by intra-arterial thrombectomy. With primary outcome defined by the functional level in a one-year follow-up, we hypothesize that patients with older age are at a disadvantage in post-stroke recovery. However, an age-threshold should be determined to help clinicians in selection of patients to undergo such therapy. Methods This is a retrospective chart review study that include 92 stroke patients in Changhua Christian hospital with a total of 68 evaluation indexes recorded. The current study utilized the forward stepwise regression model whose Adj-R2 and p-value in search of important variables for outcome prediction. The chngpt package in R indicated the threshold point of the age factor directing the better future functionality of the stroke patients. Results Datasets revealed the threshold of the age set at 79 the most appropriate. Admission Barthel Index, Age, Ipsi ICA RI, Ipsi VA PI, Contra MCA stenosis, Contra ECA RI, and in-hospital pneumonia are the significant predicting variables. The higher the age, in-hospital pneumonia, Contra MCA stenosis, Ipsi ICA RI and Ipsi VA PI, the less likely patient to recover from functional deficits as the result of acute ischemic stroke; the higher the value of Contra ECA RI and Admission Barthel Index, the better chance to recover at one-year follow up. Conclusions Parameters of pre-intervention datasets could provide important information to aid first-line clinicians in decision making. Especially, in patients whose age is above seventy-nine receives diminish return in the benefit to undergo such intervention and should be considered seriously by both the patients and the physicians.

Objectives: Endovascular treatment provides a therapeutic option for acute ischemic stroke patients who are ineligible for, or who do not respond to intravenous thrombolysis. Higher rates of recanalization by mechanical clot extraction device were reportedly associated with better clinical outcome, but the long-term patency of recanalized vessel is unknown. Methods: We retrospectively evaluated magnetic resonance angiography (MRA) at 24-hour and 3-month after the endovascular treatment in consecutive acute stroke patients who were treated with mechanical clot extraction device between Oct. 2010 and May 2012 in our institution. Results: Fourty-six patients received endovascular treatment for acute ischemic stroke and 35 were treated with mechanical clot extraction devices, Merci and/or Penumbra system, with or without adjunctive therapy. Mean age was 69±12 years, baseline median National Institutes of Health Stroke Scale score was 15 (8 to 24), and occluded vessels were the internal carotid artery in 34%, middle cerebral artery (MCA) in 54%, and vertebro-basilar artery in 11%. Successful recanalization, defined as Thrombolysis In Myocardial Infarction II or III perfusion, was obtained in 32 (91%) patients. During 24-hour after the treatment, reocclusion of the treated vessel was observed in 4 (12.5%) patients. Of 28 eligible patients, 21 (75%) patients had 3-month MRA follow-up. None of the patients had reocclusion, but clinically silent diffuse stenosis was observed in 2 (9.5%) patients. Statistically significant predictors were not identified, but both of the patients were MCA occlusion treated with Merci retriever. Conclusion: In this study, late stenosis was observed in the MCA on 3-month follow-up MRA. Long-term follow-up seems to be useful to follow the recanalized vessels, especialy when mechanical devices were used.
