Background: The value of CRP in stroke patients undergoing thrombolysis, in the acute and subacute phase of ischemic stroke as a prognostic tool for outcome is unclear, since conflicting reports exist. Aim of our study was to explore the role of admission CRP and follow-up CRP between day 1 and 7, for outcome and mortality in stroke patients treated with rtPa. Methods: From March 1998 to 2011 all patients admitted to our hospital and undergoing thrombolysis for acute ischemic stroke were included into an open, prospective database. Stroke severity was assessed using the NIHSS. In all patients CRP levels was measured upon admission in the emergency room, after 24 hours from the acute event and in the following days. CT scan before treatment and routine brain CT scan 24-36 h after thrombolysis were performed. Symptomatic haemorrhage (sICH) was defined according to ECASS II criteria. Functional outcome was assed by mRS at three months and divided into independent (mRS0-2) and dependent (mRS 3-5). Results: In total, 1292 patients were registered in our database. About 70% of patients had an increase of CRP values in the first 7 days after admission. Infection occurred in 22% of patients and about 25% had a large brain infarction (>1/3 of vessel territory). sICH occurred in 6.7% of patients. Follow-up CRP levels between day 1 and 7 were significantly associated with cardio embolic stroke (p=0.033), infarct size (p<0.001), infection (p<0.001), symptomatic haemorrhage (p<0.001), independent (p<0.001), dependent outcome (p<0.001) and mortality (p<0.001). CRP values between day 1 and 7 (OR 2.824 CI95%; 1.534 - 5.201, p=0.001), infarct size (OR 2.254; CI95% 1.480 - 3.432, p<0.001), infection (OR1.752; CI95% 1.100 - 2.789, p=0.018) and NIHSS (OR 1.043; CI95% 1.016 - 1.069, p=0.001) were independent predictors for dependent outcome. Admission CRP values were not independently associated with outcome and mortality after multivariate logistic regression analysis. Conclusion: Together with know predictors like infarct size, NIHSS and infections, maximally elevated CRP levels within day 1 and 7 were strongly and independently associated with long-term outcome in thrombolyzed stroke patients after correction for baseline variables.

Introduction Systemic contraceptives increase the risk of ischemic stroke but little is known about the characteristics, mechanisms and long-term outcome post stroke of patients on hormonal contraception. We sought to To assess characteristics and outcome of acute ischemic stroke (AIS) in young women using systemic hormonal contraceptives (SHC) and compare them to strokes in non-contraceptive users. Patients and methods Using the Acute STroke Registry and Analysis of Lausanne (ASTRAL), we analyzed demographics, risk factors, clinical, radiological and treatment data of consecutive female patients of <50 years between 2003 to 2015. We compared groups with and without SHC in a logistic regression analysis. Results Of the 179 female patients of <50 years during the observation period, 57 (39.6%) used SHC, 71.9% of whom, a combined oral contraceptive pill. On logistic regression contraceptive users were significantly younger but had comparable stroke severity. They had less migraine with aura and tobacco use, and more hyperlipidaemia. Also, contraceptive users had significantly less intra and extracranial stenosis and occlusion on arterial imaging, but more focal hypoperfusion on CT-perfusion. Undetermined mechanism of stroke was more frequent with SHC users, whereas rare mechanisms were more frequent in non-users. The contraceptive user group had a more favourable adjusted 12-month outcome with significantly fewer ischemic recurrences after stopping systemic contraception in all. Conclusion Contraceptive users with ischemic strokes are younger and have lesser tobacco use and migraine with aura and more hyperlipidemia. Their stroke mechanism is more often undetermined using a standardised work-up, and their adjusted long-term outcome is more favourable with less stroke recurrence.

The most important predictors for outcomes after ischemic stroke, that is, for health deterioration and death, are chronological age and stroke severity; gender, genetics and lifestyle / environmental factors also play a role. Of all these, only the latter can be influenced after the event, even though recurrent stroke may be prevented by antiaggregant/anticoagulant therapy, angioplasty of high-grade stenoses, and treatment of cardiovascular risk factors. Moreover, blood cell composition and protein biomarkers such as C-reactive protein or interleukins in serum are frequently considered as biomarkers of outcome. We surveyed protein biomarkers that were reported to be predictive for outcome after ischemic stroke, specifically considering biomarkers that predict long-term outcome (&ge;3 months) and that are measured over the first days following the event. We classified the protein biomarkers as immune‑inflammatory, coagulation-related, and adhesion-related biomarkers. Some of these biomarkers are closely related to cellular senescence and, in particular, to the inflammatory processes that can be triggered by senescent cells. Moreover, the processes that underlie inflammation, hypercoagulation and cellular senescence connect stroke to cancer, and biomarkers of cancer-associated thromboembolism, as well as of sarcopenia, overlap strongly with the biomarkers discussed here. Finally, we demonstrate that most of the outcome-predicting protein biomarkers form a close-meshed functional interaction network, suggesting that the outcome after stroke is partially determined by an interplay of molecular processes relating to inflammation, coagulation, cell adhesion and cellular senescence.

Background: Atrial fibrillation (AF) shares several risk factors with atherosclerosis. We investigated the association between total carotid plaque number (TPN) and long-term prognosis in ischemic stroke patients with AF. Methods: A total of 392 ischemic stroke patients with AF who underwent carotid ultrasonography were enrolled. TPN was assessed using B-mode ultrasound. The patients were categorized into two groups according to best cutoff values for TPN (TPN ≤ 4 vs. TPN ≥ 5). The long-term risk of major adverse cardiovascular events (MACE) and mortality according to TPN was investigated using a Cox hazard model. Results: After a mean follow-up of 2.42 years, 113 patients (28.8%) had developed MACE and 88 patients (22.4%) had died. MACE occurred more frequently in the TPN ≥ 5 group than in the TPN ≤ 4 group (adjusted hazard ratio [HR], 1.50; 95% confidence interval [CI], 1.01–2.21; p < 0.05). Moreover, the TPN ≥ 5 group showed an increased risk of all-cause mortality (adjusted HR, 2.69; 95% CI, 1.40–5.17; p < 0.05). TPN along with maximal plaque thickness and intima media thickness showed improved prognostic utility when added to the variables of the CHAD2DS2-VASc score. Conclusion: TPN can predict the long-term outcome of ischemic stroke patients with AF. Adding TPN to the CHAD2DS2-VASc score increases the predictability of outcome after stroke.

Stroke Patients

Atrial fibrillation (AF) is a common arrhythmia and a major risk factor for ischemic stroke, especially in the elderly. Patients with nonvalvular AF have a 5-fold excess risk of stroke. However, population-based data are scarce in patients who have experienced a first-ever ischemic stroke in the presence of AF regarding long-term risk of stroke recurrence and case-fatality rate. Aim of the study is to find out the outcome of ischemic stroke patients with Atrial Fibrillation. It was a descriptive type cross sectional study where 125 diagnosed cases of ischemic stroke were included. Presence of atrial fibrillation was detected by electrocardiogram. They were divided into two groups – those with atrial fibrillation and those without. Comparison was done between the two group in term of recurrence, mortality and clinical improvement. Atrial fibrillation was present in 22 (17.6%) of 125 patients with ischemic stroke. Those with AF were more frequently male, aged 45 years and older. The presence of AF was associated with high 3 months (Χ2 =4.562, df = 1, p<0.05) and 6 months mortality (Χ2 =7.868, df = 1, p<0.05), with a higher stroke recurrence rate within the first 6 months follow-up (22.7% versus 7.8% (<0.05)). At 3 months follow up clinical deterioration was noted in 9.1% patient with atrial fibrillation compared to 2.9% patients who had no arrhythmia(p<0.01) and at 6 months follow up clinical deterioration was noted in 18.2% patient with atrial fibrillation compared to 4.9% patients who had no arrhythmia(p<0.01). Ischemic stroke patients with atrial fibrillation had significant mortality within the study period compared to those without atrial fibrillation. Significant deterioration in clinical outcome was noted in atrial fibrillation group after six months. Recurrence was more in ischemic stroke patients with atrial fibrillation. Multivariate linear regression analysis shows atrial fibrillation as well as CKD, Diabetes mellitus and smoking as independent risk factor for recurrence. In conclusion, patients who had an ischemic stroke with accompanying atrial fibrillation had higher mortality, grave stroke severity, more recurrences and poorer functional status than those without atrial fibrillation.TAJ 2015; 28(2): 1-6

Background: One intriguing aspect of stroke is its higher incidence in men as compared to women. Endogenous sex hormones, testosterone and estradiol, may be responsible for this difference. This research aims to study serum testosterone and estradiol levels in men with acute ischemic stroke (AIS) and to correlate these levels with National Institutes of Health Stroke Scale (NIHSS) score and infarct size in computed tomography (CT). Methods: 100 male patients with AIS and 100 age-matched controls were included in this case-control study. Patients with hemorrhagic stroke, taking hormonal preparations, or suffering from chronic illnesses like tuberculosis (TB), cancer, etc. were excluded. Complete history was obtained including presence of established risk factors and physical examination was done in cases and controls with informed written consent. Severity of stroke in cases was assessed by the NIHSS. CT scan of brain was performed within 72 hours of patient’s admission to hospital. The infarct size was measured in centimeters as the largest visible diameter of the infarct on CT scan. Fasting blood samples were obtained for routine investigations and estimating estradiol and testosterone levels. Results: Mean total testosterone level in cases (223.30 ± 143.44 ng/dl) was significantly lower than that of controls (515.34 ± 172.11 ng/dl) (P < 0.001), while estradiol levels had no significant statistical difference (P = 0.260). A significant inverse correlation was found between total testosterone levels and stroke severity (r = -0.581, P < 0.001) and also, total testosterone levels and infarct size (r = -0.557, P < 0.001). Estradiol levels in patients had no significant correlation with stroke severity (P = 0.618) or infarct size (P = 0.463). Conclusion: Low testosterone levels are associated with increased stroke severity and infarct size in men. Further studies are required to establish whether low testosterone is a cause or effect of ischemic stroke and also to explore the potential benefits of testosterone supplementation in men with AIS.

The Relationship

Aim:The study was undertaken with the aim to establish the denite correlation between serum albumin levels and outcome of ischemic stroke. Methodology: The present observational study was conducted on 100 acute ischemic stroke patients meeting inclusion and exclusion criteria. All patients were investigated for hypoalbuminemia and their stroke severity was assessed by NIHSS score on day 1 and day 7. The relationship between admission albumin levels, NIHSS values and outcome of those patients was ascertained. Results: There was increased prevalence of hypoalbuminemia in AIS patients and there was signicant correlation between NIHSS score on day 1&7, mortality and hypoalbuminemia in AIS patients and there was signicant association between high NIHSS score and mortality in AIS patients. Conclusion: serum albumin is an independent predictor of functional outcome following an acute ischemic stroke and serum albumin level is inversely correlated with severity of stroke at presentation.

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.

Backgrounds Atherosclerosis of vertebrobasilar artery is a major cause of the ischemic stroke in the posterior circulation. Vertebral artery ostium stenosis (VAOS) is occasionally observed in patients with acute ischemic stroke in anterior or posterior circulation. However, VAOS as a risk for stroke recurrence, especially for the posterior circulation stroke, has not been well studied. This study was performed to determine long-term outcome and clinical significance of VAOS in acute ischemic stroke patients. Methods As a prospective observational study of single stroke center registry, we studied risk of recurrent stroke and vascular outcome in acute ischemic stroke patients with VAOS, recruited consecutively from December 2007 to December 2010. VAOS was defined as more than 50% stenosis of either vertebral artery ostium on a contrast-enhanced MRA. Vascular risk factors and long-term outcome including recurrent stroke, cardiovascular event, vascular mortality, or all-cause mortality were investigated. Results Of 773 acute ischemic stroke patients, underwent contrast-enhanced MRA, 149 (19.2%) had more than 50% VAOS (age, 70±10 years). All patients had intensive medical treatment and 11 patients underwent angioplasty and stenting. During 327 patient-years of follow-up (mean, 2.2 years), there were 8 ischemic (3 in posterior circulation, 5 in anterior circulation), 5 hemorrhagic, and 2 unknown stroke. The annual rate of events were 1.36% for posterior circulation ischemic stroke, 3.64% for all ischemic stroke, 5.91% for all stroke, 1.36% for vascular death, and 9.55% for all cause mortality. Symptomatic VAOS, concomitant stenosis of other vertebrobasilar arteries or carotid arteries, or stroke subtype was not associated with long-term outcome. Conclusions Long-term outcome of acute ischemic stroke patients with more than 50% VAOS was favorable on intensive medical treatment and selective angioplasty and stenting. Vertebral artery ostium stenosis may not be a major risk factor for the recurrent ischemic stroke in the posterior circulation.
