Background and objectives: Patients with a history of prior stroke have a high risk for subsequent cardiovascular events (CVD). Therefore, the implementation of an effective strategy to reduce risk factors and thereby improve secondary prevention outcomes is crucial in this patient population. The aim of this study was to determine differences in the incidence of risk factors for recurrent CVD events based on clinical type of prior stroke and to characterize them using the ICF (International Classification of Functioning, Disability and Health) classification system. Materials and Methods: The incidence of risk factors for recurrent CVD events were retrospectively analyzed in 109 patients with a history of ischemic stroke (IS) and 80 patients with a history of intracerebral hemorrhage (ICH) within 14 days poststroke. Results: Atrial fibrillation/flutter (p = 0.031), >70% carotid artery stenosis (p = 0.004), blood pressure >140/90 mmHg (p = 0.025), blood HbA1c levels >7% (p = 0.002), smoking (p = 0.026) and NSAID (nonsteroidal anti-inflammatory drug) use (p < 0.001) were significantly more common in patients with a history of ischemic stroke. However, liver function test abnormalities were observed more commonly in patients with a history of hemorrhagic stroke (p = 0.025). Conclusions: The incidence and type of risk factors for recurrent CVD events vary according to the clinical type of prior stroke. The ICF classification system is a useful tool for evaluating these risk factors. This may help reduce the risk of subsequent CVD events.

Background: Optimal prescribing of oral anticoagulants, for the prevention of stroke in patients with atrial fibrillation, requires clinicians to estimate the competing risk of ischemic stroke and intracerebral hemorrhage (ICH). However, a number of risk factors increase the risk of both ischemic stroke and ICH (e.g. age, hypertension and chronic renal disease), and it is unclear how these ‘shared’ risk factors should influence decisions on antithrombotic therapy. Objective: To determine the comparative importance of risk factors for ischemic stroke and ICH in patients with atrial fibrillation, focusing primarily on risk factors included in the CHA2DS2VASC (risk of ischemic stroke) and HAS-BLED (risk of major bleeding) scores. Methods: Prospective registry of 3,197 patients admitted with acute ischemic stroke or ICH and atrial fibrillation included in the Registry of the Canadian Stroke Network (Jul 03-Mar 08; 11 Regional Stroke Centers in Ontario, Canada). Multivariable analysis was used to determine the association between baseline risk factors (age, sex, history of hypertension, previous stroke or transient ischemic attack, history of congestive heart failure, history of vascular disease, hepatic impairment, current alcohol intake, history of diabetes mellitus, history of gastro-intestinal bleeding, renal impairment, admission INR and antiplatelet therapy) and risk of ischemic stroke versus ICH. Results: Of 3,197 patients with atrial fibrillation and acute stroke, 2,806 (87.8%) presented with an ischemic stroke and 391 (12.2%) presented with an ICH. Of the ‘shared’ risk factors, age (OR 1.17; 95% CI 1.04-1.31 per decade) and previous history of stroke (OR 1.40; 95% CI 1.09-1.81) were associated with an increased risk of ischemic stroke relative to ICH, while a history of hypertension (OR 0.90; 95% CI 0.69-1.18) and renal impairment (OR 1.29; 0.96-1.72) were not associated with either stroke subtype, on multivariable analyses. Of the ‘non-shared’ risk factors, alcohol consumption of <2 units/day vs. no consumption (OR 1.61; 95% CI 1.24-2.09), female sex (OR 1.53; 95% CI 1.20-1.96) and a history of vascular disease (OR 1.73; 95% CI 1.30- 2.30) were associated with an increased risk of ischemic stroke relative to ICH. Elevated INR at the time of admission was a significant predictor of ICH, relative to ischemic stroke. Conclusion: None of the ‘shared’ risk factors were stronger predictors of ICH compared to ischemic stroke, which has obvious implications for clinical practice. In particular, older age was more strongly associated with ischemic stroke than ICH in patients with atrial fibrillation, and therefore, should be considered as a factor favoring a decision to commence anticoagulant therapy.

Introduction : Multiple factors have been reported to influence the time between onset of symptoms in acute ischemic stroke and hospital presentation. Although education level is one independent factor in presentation, as we previously reported, health literacy has not been fully assessed regarding specific patient knowledge on stroke or its known risk factors. This study aims to determine whether having a history of vascular risk factors such as prior stroke, coronary artery disease (CAD), or atrial fibrillation (AF) influence presentation time and acute ischemic stroke therapy utilization. Methods : This study included 250 acute ischemic stroke patients presenting to a large academic community hospital from February to December 2018. Educational level was defined within four categories: Grade School, High School, College or Higher, and Unknown. Last seen normal, symptom onset, and arrival times were acquired. Vascular risk factors chosen for this study included prior stroke, CAD, and AF. History of vascular risk factors was verified by medical documentation showing prior diagnosis by physician. Initial NIH Stroke Scale score, stroke location, vessel involved, LDL, hemoglobin A1c, gender, and race were also obtained. Patients were categorized based on their level of education, the presence or absence of vascular risk factors, and utilization of tPA or thrombectomy (MT). The primary outcomes were onset‐to‐arrival time (OTA), in minutes, and utilization rates of acute ischemic stroke therapies (either tPA, MT, or both). Subgroup analysis was conducted to associate education level with each vascular risk factor, comparing OTA and acute ischemic stroke therapy utilization rate. Results : As previously reported, educational level was inversely associated with OTA and positively associated with utilization of at least one acute ischemic stroke therapy. Prior stroke, CAD, and AF showed a substantial OTA decrease for all education groups except for College. Prior stroke decreased OTA in Grade School by 24% (764 vs. 579); High School by 30% (222 vs. 154) and College by 20% (52 vs. 41). CAD decreased OTA in Grade School by 65% (734 vs. 253), High School by 14% (209 vs. 180), and College by 3% (50 vs 49). AF decreased OTA in Grade School by 88% (764 vs. 91) and High School by 56% (216 vs. 95), but increased in College by 35% (47 vs. 64). History of prior stroke decreased utilization of both tPA and MT by 14%; CAD increased tPA use by 8% and MT by 5%; while AF increased tPA use by 9% and MT by 12%. Conclusions : Having at least one prior vascular risk factor (prior stroke, CAD, AF), diagnosed by a physician, was associated with lower OTA in Grade School and High School educated patients. A history of prior stroke was associated with lower acute stroke therapy utilization (tpa and MT), while both CAD and AF were associated with increased acute stroke therapy utilization.

Background and Purpose— It has been suggested that statins increase the risk of intracerebral hemorrhage in individuals with a history of stroke, which has led to a precautionary principle of avoiding statins in patients with prior intracerebral hemorrhage. However, such prescribing reticence may be unfounded and potentially harmful when considering the well-established benefits of statins. This study is so far the largest to explore the statin-associated risk of intracerebral hemorrhage in individuals with prior stroke. Methods— We conducted a population-based, propensity score–matched cohort study using information from Danish national registers. We included all individuals initiating statin treatment after a first-time stroke diagnosis (intracerebral hemorrhage, N=2728 or ischemic stroke, N=52 964) during 2002 to 2016. For up to 10 years of follow-up, they were compared with a 1:5 propensity score–matched group of statin nonusers with the same type of first-time stroke. The difference between groups was measured by adjusted hazard ratios for intracerebral hemorrhage calculated by type of first-time stroke as a function of time since statin initiation. Results— Within the study period, 118 new intracerebral hemorrhages occurred among statin users with prior intracerebral hemorrhage and 319 new intracerebral hemorrhages in users with prior ischemic stroke. The risk of intracerebral hemorrhage was similar for statin users and nonusers when evaluated among those with prior intracerebral hemorrhage, and it was reduced by half in those with prior ischemic stroke. These findings were consistent over time since statin initiation and could not be explained by concomitant initiation of other medications, by dilution of treatment effect (due to changes in exposure status over time), or by healthy initiator bias. Conclusions— This large study found no evidence that statins increase the risk of intracerebral hemorrhage in individuals with prior stroke; perhaps the risk is even lower in the subgroup of individuals with prior ischemic stroke.

Abstract Hemorrhagic stroke (HS) is a major cause of death and disability worldwide, despite being less common, it presents more aggressively and leads to more severe sequelae than ischemic stroke. There are two types of HS: Intracerebral Hemorrhage (ICH) and Subarachnoid Hemorrhage (SAH), differing not only in the site of bleeding, but also in the mechanisms responsible for acute and subacute symptoms. This is a systematic review of databases in search of works of the last five years relating to the comprehension of both kinds of HS. Sixty two articles composed the direct findings of the recent literature and were further characterized to construct the pathophysiology in the order of events. The road to the understanding of the spontaneous HS pathophysiology is far from complete. Our findings show specific and individual results relating to the natural history of the disease of ICH and SAH, presenting common and different risk factors, distinct and similar clinical manifestations at onset or later days to weeks, and possible complications for both.

Risk factors for ischemic stroke is suggested to differ by etiologic subtypes. The purpose of this study was to examine the associations between modifiable and non-modifiable risk factors and atherothrombotic stroke (i.e., excluding cardioembolic stroke), and to examine if the potential benefit of modifiable lifestyle factors differs among subjects with and without predisposing comorbidities. After a median follow-up of 21.2 years, 2339 individuals were diagnosed with atherothrombotic stroke out of 26,547 study participants from the Malmö Diet and Cancer study. Using multivariable Cox regression, we examined non-modifiable (demographics and family history of stroke), semi-modifiable comorbidities (hypertension, dyslipidemia, diabetes mellitus and atherosclerotic disease), and modifiable (smoking, body mass index, diet quality, physical activity, and alcohol intake) risk factors in relation to atherothrombotic stroke. Higher age, male gender, family history of stroke, and low educational level increased the risk of atherothrombotic stroke as did predisposing comorbidities. Non-smoking (hazard ratio (HR) = 0.62, 95% confidence interval (CI) 0.56–0.68), high diet quality (HR = 0.83, 95% CI 0.72–0.97) and high leisure-time physical activity (HR = 0.89, 95% CI 0.80–0.98) decreased the risk of atherothrombotic ischemic stroke independent of established risk factors, with non-significant associations with body mass index and alcohol intake. The effect of the lifestyle factors was independent of predisposing comorbidities at baseline. The adverse effects of several cardiovascular risk factors were confirmed in this study of atherothrombotic stroke. Smoking cessation, improving diet quality and increasing physical activity level is likely to lower risk of atherothrombotic stroke in the general population as well as in patient groups at high risk.

Background Stroke not only substantially increases the risk of incident dementia early after stroke, the risk remains elevated years after. Aim We aimed to determine the risk factors of dementia onset more than 3-6 months after stroke or transient ischemic attack (TIA). Methods This is a single center prospective cohort study. We recruited consecutive subjects with stroke/TIA without early-onset dementia. We conducted an annual neuropsychological assessment for 5 years. We investigated the association between baseline demographic, clinical, genetic (APOEε4 allele), and radiological factors, as well as incident recurrent stroke, with delayed-onset dementia using Cox proportional hazards models. Results 1,007 patients were recruited, of which 88 with early-onset dementia and 162 who lost to follow-ups were excluded. 49 (6.5%) out of 757 patients have incident delayed-onset dementia. The presence of ≥ 3 lacunes, history of ischemic heart disease (IHD), history of ischemic stroke and a lower baseline Hong Kong version of the Montreal Cognitive Assessment (MoCA) score, were significantly associated with delayed-onset dementia. APOEε4 allele, medial temporal lobe atrophy, and recurrent stroke were not predictive. Conclusion The presence of ≥ 3 lacunes, history of IHD, history of ischemic stroke and a lower baseline MoCA score, are associated with delayed-onset dementia after stroke/TIA.

Introduction: Ischemic stroke is the cause for major morbidity and mortality in reversible cerebral vasoconstriction syndrome (RCVS). While there is evidence to suggest that ischemic stroke in RCVS is associated with proximal vasoconstriction, it is still unclear why some patients develop ischemic lesions. The aim of this study was to evaluate the risk factors and outcomes of ischemic stroke in RCVS. Methods: We utilized the Nationwide Readmissions Database 2016-2017 to identify all hospitalizations with the discharge diagnosis of RCVS. Occurrence of acute ischemic stroke was identified. Hospitalizations with the diagnosis of hemorrhagic stroke were excluded. Survey design methods were used to generate national estimates. Independent predictors of ischemic stroke were analyzed using multivariable logistic regression analysis with results expressed as odds ratio (OR) and 95% confidence intervals (CI). Results: Among the total 1,065 hospitalizations for RCVS during the study period (mean±SD age: 49.0±16.7 years, female 69.7%), 267 (25.1%) had occurrence of acute ischemic stroke. Patients with ischemic stroke were more likely to have history of hypertension (OR 2.33, 95% CI 1.51-3.60), diabetes (OR 1.81, 95% CI 1.11-2.98), and tobacco use (OR 1.64, 95% CI 1.16-2.33) and less likely to have a history of migraine (OR 0.56, 95% CI 0.35-0.90). Patients with stroke were more likely to develop cerebral edema. They also had longer hospital stay, higher hospital charges, and lower likelihood of being discharged to home or inpatient rehabilitation facility. They had higher in-hospital mortality rate, the difference was however not statistically significant. Conclusion: In conclusion, ischemic stroke affects nearly 25% of patients with RCVS and is associated with an increased rate of other neurologic complications and worse functional outcomes. Patients with traditional cerebrovascular risk factors might have a higher predisposition for developing the ischemic lesions.

Vorapaxar is an antiplatelet agent that potently inhibits thrombin-mediated activation of the platelet protease-activated receptor (PAR)-1. Phase 2 trials of vorapaxar suggested efficacy with acceptable safety in patients with ischemic stroke. Methods: TRA 2°P–TIMI 50 was a multinational, randomized, double-blinded, placebo-controlled trial of 26449 patients with a history of atherothrombosis randomized to vorapaxar (2.5 mg daily) or matching placebo added to standard therapy, including antiplatelet agents. Patients who qualified with stroke (N=4883) had a history of ischemic stroke in the prior 2 wks to 12 mo. The first efficacy endpoint was the composite of cardiovascular (CV) death, MI, or stroke. After 2 years, the Data and Safety Monitoring Board recommended discontinuation of study treatment in patients with prior stroke. Results: The qualifying stroke was classified as large vessel in 35%, small vessel in 47%, and other in 18%. Background therapy included aspirin in 81%, clopidogrel in 22%, and dipyridamole in 19%. In the stroke cohort, the 3-year rate of CV death, MI, or stroke was not reduced with vorapaxar vs. placebo (13.0% vs. 11.7%, HR 1.03; 95% CI 0.85-1.25), including recurrent ischemic stroke (HR 0.99; 95% CI 0.78-1.25). There were no statistically significant differences in the effect of vorapaxar based on the type or timing of the qualifying stroke, and a borderline interaction based on co-administration of clopidogrel (Figure) The rate of intracranial hemorrhage (ICH) at 3 years was 2.5% with vorapaxar vs. 1.0% with placebo (HR 2.52; 95% CI 1.46-4.36). Conclusions: In patients with prior stroke receiving standard antiplatelet therapy, adding vorapaxar increased the risk of ICH without a reduction in the primary efficacy endpoint or ischemic stroke. These findings add to the accumulating evidence establishing important risks with combination antiplatelet therapy in patients with prior stroke.

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.
