Introduction. Stroke is the second cause of mortality worldwide, after the ischemic coronary disease, and the first cause of long term-disability. Recent studies report that ischemic stroke (IS) in young patients is increasing in incidence, even though the overall stroke hospitalization rate is decreasing. Stroke in the young, working individuals significantly affects the quality of life (QoL) and also determines an important, negative economic impact by reducing the workforce. Material and method. The aim of this paper is to present the results of a 4-year observational, retrospective study on all patients between 18-49 years, who suffered from acute IS and were admitted and investigated in the Neurology Clinic of Sibiu and the CVASIC Research Center. Clinical evaluations, imaging investigations, and risk factor evaluations were performed on all patients in order to elucidate the etiology and organize according to the TOAST classification. Results and discussions. 114 patients with ischemic stroke were included in the study. 76% of the subjects fall into the 40-49 age class. In respect to the TOAST classification, most cases of IS were of UE (rural<urban), while the fewest cases of IS were represented by SAA in both populations. The most frequent vascular risk factors were hypertension, dyslipidemia, smoking and thrombophilia. Confirmed cervical arteries dissection caused 2/3 of the severe carotid stenosis and 45,5% of the carotid occlusions. Conclusions. Hypertension, dyslipidemia and smoking are the main risk factors for stroke in young patients. The most common TOAST stroke subtype was stroke of undetermined etiology, followed by stroke of other determined etiology (carotid artery dissection and thrombophilia).

Introduction: Few studies have compared the proportion of ischemic strokes attributable to traditional vascular risk factors (population-attributable risk percent or PAR%) between genders and races. The PAR% is a function of the population prevalence and strength of association of a risk factor. Methods: A population-based case-control study of ischemic stroke in young adults ages 18-49 in the Baltimore-Washington region was used to study the prevalence, odds ratios, and PAR% of hypertension, diabetes, and smoking among blacks and whites. Logistic regression was used to calculate age-adjusted odds ratios. All analyses were stratified by gender. Results: There were 1044 cases and 1099 controls. Of the cases, 47% were black, 54% were women. Roughly a quarter to a third of all strokes in women were attributable to smoking. Due to the higher prevalence of hypertension and a higher odds ratio for hypertension in black men (OR 3.9, 95% CI 2.6-5.9) compared to white men (OR 1.8, 95% CI 1.3-2.6), there was a much higher PAR% for hypertension among black men than white men. See Table 1 for prevalence and Table 2 for PAR% stratified by gender and race. Conclusion: Traditional vascular risk factors have the potential to explain a high proportion of ischemic stroke in young adults. The high proportion of strokes in women attributable to smoking underscores the need for targeted smoking cessation interventions in this population. Diabetes and, especially, hypertension are important contributors to the excess population burden of ischemic stroke among blacks. These findings support the value of early screening and treatment for hypertension in young blacks.

Background: The relation between serum lipids and ischemic stroke remains controversial in young patients. The aim was to determine the serum lipid profile and the vascular risk factors for ischaemic stroke in a series of patients under 45 with an ischemic stroke and to compare them with a series of controls of the same age. Material and method: This case-control study was conducted in the Department of Neurology and Department of Biochemistry of BSMMU, Dhaka, between the period of July 2007 and June 2009 for duration of two years. A total number of 50 patients presented with recent ischemic stroke and 50 control person were enrolled in this study. All patients of both sexes, aged between 15 to 45 years presented with ischemic stroke, from 0 day to 1 month that was confirmed by CT scan of head/MRI of brain. Vascular risk factors were recorded and blood sample was collected from the cases and the controls and analyzed at the Dept. of Biochemistry, BSMMU for estimation of serum fasting lipid profile. Result: Multivariate analyses showed that other than serum lipids- family history of dyslipidaemia, family history of stroke or TIA, history of HTN and smoking habit are found significant risks for stroke in young adult. Conclusion: The present study does not confirm the role of serum lipids as risk factors for ischemic stroke in young adult. Other than serum lipids- family history of dyslipidaemia, family history of stroke or TIA, history of HTN and smoking habit are found significant risks for stroke in young adult.

Background: Atherosclerotic stenosis of large IC arteries is an important cause of stroke. The prevalence of ICS in stroke population differs by ethnicity.We report the frequency of ICS among a global sample of patients with non-lacunar cryptogenic ischemic stroke (NLCIS) who did not have another identifiable cause for stroke i.e. cardioembolic, extracranial LAD, or other specific causes. Hypothesis: We hypothesized that the prevalence rates of ICS will differ according to global regions. Methods: Consecutive patients with recent ischemic stroke were retrospectively surveyed at 19 stroke centers in 19 countries to identify the frequency of IC imaging and its yield. Countries were grouped by World Bank regions. ICS was considered to be significant if there was >50% stenosis in the arteries proximal to the index stroke evidenced by MRA, CTA or TCD. Results: We identified a total of 2145 consecutive ischemic stroke patients among which 475 had NLCIS. IC arterial imaging was carried-out,on average, in 87% of patients. Of these 414 patients, 15% had stenosis proximal to the area of brain ischemia. The frequency of ICS among NLCIS patients was highest in East Asia (27%) and lowest in Pacific (4%). Patients with ICS in Latin America were significantly younger when compared to other 4 regions. Conclusion: IC arterial imaging is carried out in majority of stroke centers in patients with NLCIS, among whom the fraction of IS associated with ICS is substantial throughout the world, averaging about 15%. MRA / CTA had a higher yield than TCD. On average these patients have traditional vascular risk factors except for Latin American patients who are significantly younger with no vascular risk factors.

Introduction: Intravascular calcification is thought to be a marker of atherosclerosis in patients with stenosis and vascular risk factors. Little is known about the utility of quantifying intracranial calcification to help determine mechanism of stenosis. The objective of our study was to compare presence and patterns of intracranial calcification in patients with intracranial stenosis due to atherosclerosis and other etiologies. Methods: Retrospective cohort study of 89 patients < 50 years with diagnosis of intracranial stenosis who had undergone CT angiogram from 2008-2013; 44 had presumed atherosclerosis as etiology ( > 3 vascular risk factors with no other identified cause). CTAs were reviewed for presence and location of intracranial calcification. Results: Of patients with atherosclerotic stenosis, 28 (64%) had intravascular calcification compared to 16 (36%) of those with stenosis of other etiologies (P=0.0039). There was no significant difference in pattern or location of stenosis between groups. One-third had calcification outside the region of stenosis in both groups. Distal internal carotid artery and distal vertebral artery were the most common sites of intracranial calcification (Table). Conclusion: Intracranial calcification is more commonly seen in patients < 50 years old with stenosis secondary to atherosclerosis, but the pattern and location was similar between groups. More research is needed to determine the utility of using the presence of vascular calcification to help determine mechanism of intracranial stenosis in the young.

Introduction: White matter hyperintensity (WMH) is a highly heritable trait and a significant contributor to stroke risk and severity. Vascular risk factors contribute to WMH severity; however, knowledge of the determinants of WMH in acute ischemic stroke (AIS) is still limited. Hypothesis: WMH volume (WMHv) varies across AIS subtypes and is modified by vascular risk factors. Methods: We extracted WMHv from the clinical MRI scans of 2683 AIS subjects from the MRI-Genetics Interface Exploration (MRI-GENIE) study using a novel fully-automated, volumetric analysis pipeline. Demographic data, stroke risk factors and stroke subtyping for the Causative Classification of Stroke (CCS) were performed at each of the 12 international study sites. WMHv was natural log-transformed for linear regression analyses. Results: Median WMHv was 5.7cm 3 (interquartile range (IQR): 2.2-12.8cm 3 ). In univariable analysis, age (63.1 ± 14.7 years, β=0.04, SE=0.002), prior stroke (10.2%, β=0.66, SE=0.08), hypertension (65.4%, β=0.75, SE=0.05), diabetes mellitus (23.1%, β=0.35, SE=0.06), coronary artery disease (17.6%, β=0.04, SE=0.002), and atrial fibrillation (14.6%, β=0.48, SE=0.07) were significant predictors of WMHv (all p<0.0001), as well as smoking status (52.2%, β=0.15, SE=0.05, p=0.005), race (16.5% Non-Caucasian, β=0.25, SE=0.07) and ethnicity (8.2% Hispanic, β=0.30, SE=0.11) (all p<0.01). In multivariable analysis, age (β=0.04, SE=0.002), prior stroke (β=0.56, SE=0.08), hypertension (β=0.33, SE=0.05), smoking status (β=0.16, SE=0.05), race (β=0.42, SE=0.06), and ethnicity (β=0.34, SE=0.09) were independent predictors of WMHv (all p<0.0001), as well as diabetes mellitus (β=0.13, SE=0.06, p=0.02). WMHv differed significantly (p<0.0001, unadjusted) across CCS stroke subtypes: cardioembolic stroke (8.0cm 3 , IQR: 4.2-15.4cm 3 ), large-artery stroke (6.9cm 3 , IQR: 3.1-14.7cm 3 ), small-vessel stroke (5.8cm 3 , IQR: 2.5-13.5cm 3 ), stroke of undetermined (4.7cm 3 , IQR: 1.6-11.0cm 3 ) or other (2.55cm 3 , IQR: 0.9-8.8cm 3 ) causes. Conclusion: In this largest-to-date, multicenter hospital-based cohort of AIS patients with automated WMHv analysis, common vascular risk factors contribute significantly to WMH burden and WMHv varies by CCS subtype.
