Characteristics associated with occurrence of stroke in patients with infective endocarditis - a retrospective cohort study.

BACKGROUND: Stroke is a severe complication of infective endocarditis (IE), associated with high rates of mortality. Data on how IE patients with and without stroke differ may help to improve understanding contributing mechanisms. METHODS: All patients treated for IE between 2019 and 2021 with and without associated stroke were identified from the medical records of three academic tertiary care hospitals in Germany, all part of Charité - Universitätsmedizin Berlin, Germany. Multivariable logistic regression analyses were performed to identify variables associated with the occurrence of stroke. RESULTS: The study population consisted of 353 patients diagnosed with IE. Concomitant stroke occurred in 96/353 (27.2%) patients. Acute stroke was independently associated with co-occurring extracerebral arterial embolism [adjusted Odds ratio (aOR = 2.52; 95% confidence interval (CI) 1.35-4.71)], acute liver failure (aOR = 2.62; 95% CI 1.06-6.50), dental focus of infection (aOR = 3.14; 95% CI 1.21-8.12) and left-sided IE (aOR = 28.26; 95% CI 3.59-222.19). Stroke was found less often in IE patients with congenital heart disease (aOR = 0.20; 95% CI 0.04-0.99) and atypical pathogens isolated from blood culture (aOR = 0.31; 95% CI 0.14-0.72). CONCLUSIONS: Stroke is more likely to occur in individuals with systemic complications affecting other organs, too. Special attention should be addressed to dental status. The low incidence of stroke in patients with congenital heart disease may reflect awareness and prophylactic measures.

Myocardial injury in patients with acute ischemic stroke detected by cardiovascular magnetic resonance imaging.

BACKGROUND: Patients with acute ischemic stroke (AIS) are at high risk of adverse cardiovascular events. Until now, the burden of myocardial injury derived from cardiovascular magnetic resonance imaging (CMR) has not been established in this population. METHODS: Patients with AIS underwent CMR at 3 Tesla within 120 h after the index stroke as part of a prospective, single-center study. Patients with persistent atrial fibrillation were excluded. Morphology and function of both cardiac chambers and atria were assessed applying SSFP cine. Myocardial tissue differentiation was based on native and contrast-enhanced imaging including late gadolinium enhancement (LGE) after 0.15 mmol/kg gadobutrol for focal fibrosis and parametric T2- and T1-mapping for diffuse findings. To detect myocardial deformation global longitudinal (GLS), circumferential (GCS) and radial (GRS) strain was measured applying feature tracking. Cardiac troponin was measured using a high-sensitivity assay (99th percentile upper reference limit 14 ng/L). T2 mapping values were compared with 20 healthy volunteers. RESULTS: CMR with contrast media was successfully performed in 92 of 115 patients (mean age 74 years, 40% female, known myocardial infarction 6%). Focal myocardial fibrosis (LGE) was detected in 31 of 92 patients (34%) of whom 23/31 (74%) showed an ischemic pattern. Patients with LGE were more likely to have diabetes, prior myocardial infarction, prior ischemic stroke, and to have elevated troponin levels compared to those without. Presence of LGE was accompanied by diffuse fibrosis (increased T1 native values) even in remote cardiac areas as well as reduced global radial, circumferential and longitudinal strain values. In 14/31 (45%) of all patients with LGE increased T2-mapping values were detectable. CONCLUSIONS: More than one-third of patients with AIS have evidence of focal myocardial fibrosis on CMR. Nearly half of these changes may have acute or subacute onset. These findings are accompanied by diffuse myocardial changes and reduced myocardial deformation. Further studies, ideally with serial CMR measurements during follow-up, are required to establish the impact of these findings on long-term prognosis after AIS.

Outcomes after reperfusion therapies in patients with ACA stroke: A multicenter cohort study from the EVATRISP collaboration.

BACKGROUND: Patients with stroke secondary to occlusions of the anterior cerebral artery (ACA) often have poor outcomes. The optimal acute therapeutic intervention for these patients remains unknown. METHODS: Patients with isolated ACA-stroke were identified from 10 centers participating in the EndoVascular treatment And ThRombolysis in Ischemic Stroke Patients (EVATRISP) prospective registry. Patients treated with endovascular thrombectomy (EVT) were compared to those treated with intravenous thrombolysis (IVT). Odds ratios with 95% confidence intervals (OR; 95%CI) were calculated using multivariate regression analysis. RESULTS: Included were 92 patients with ACA-stroke. Of the 92 ACA patients, 55 (60%) were treated with IVT only and 37 (40%) with EVT (±bridging IVT). ACA patients treated with EVT had more often wake-up stroke (24% vs. 6%, p = 0.044) and proximal ACA occlusions (43% vs. 24%, p = 0.047) and tended to have higher stroke severity on admission [NIHSS: 10.0 vs 7.0, p = 0.054). However, odds for favorable outcome, mortality or symptomatic intracranial hemorrhage did not differ significantly between both groups. Exploration of the effect of clot location inside the ACA showed that in patients with A1 or A2/A3 ACA occlusions the chances of favorable outcome were not influenced by treatment allocation to IVT or EVT. DISCUSSION: Treatment with either IVT or EVT could be safe with similar effect in patients with ACA-strokes and these effects may be independent of clot location within the occluded ACA.

Myocardial injury in transient global amnesia: a case-control study.

BACKGROUND AND PURPOSE: Elevation of cardiac troponin (cTn), a sensitive biomarker of myocardial injury, is frequently observed in severe acute neurological disorders. Case reports suggest that cardiac dysfunction may also occur in patients with transient global amnesia (TGA). Until now, no study has systematically assessed this phenomenon. METHODS: We performed a case-control study using data of consecutive patients presenting with TGA from 2010 to 2015. Multiple logistic regression analysis accounting for age, sex and cardiovascular risk factors was performed to compare the likelihood of myocardial injury [defined as elevation of cTn > 99th percentile (≥14 ng/L); highly sensitive cardiac troponin T assay] in TGA with three reference groups: migraine with aura, vestibular neuritis and transient ischaemic attack (TIA). RESULTS: Cardiac troponin elevation occurred in 28 (25%) of 113 patients with TGA. Patients with TGA with cTn elevation were significantly older, more likely to be female and had higher blood pressure on admission compared with those without. The likelihood of myocardial injury following TGA was at least more than twofold higher compared with all three reference groups [adjusted odds ratio, 5.5; 95% confidence interval (CI), 1.2-26.4, compared with migraine with aura; adjusted odds ratio, 2.2; 95% CI, 1.2-4.4, compared with vestibular neuritis; adjusted odds ratio, 2.3; 95% CI, 1.3-4.2, compared with TIA]. CONCLUSIONS: One out of four patients with TGA had evidence of myocardial injury as assessed by highly sensitive cTn assays. The likelihood of myocardial injury associated with TGA was even higher than in TIA patients with a more pronounced cardiovascular risk profile. Our findings suggest the presence of a TGA-related disturbance of brain-heart interaction that deserves further investigation.

Characteristics associated with outcome in patients with first-ever posterior fossa stroke.

BACKGROUND AND PURPOSE: Factors such as infarct volume, infarct location and symptom severity can considerably influence long-term outcome in posterior fossa strokes. The decision about therapy can sometimes be complicated by discrepancies between infarct volume and clinical severity. We aimed to evaluate imaging and clinical parameters possibly influencing long-term outcome in patients with first-ever posterior fossa stroke. METHODS: Imaging was performed on a 3-T magnetic resonance imaging scanner. Sixty-one of 1795 patients from the observational 1000Plus and LOBI studies (NCT00715533 and NCT02077582, clinicaltrials.org) were enrolled, meeting the inclusion criteria of first-ever posterior fossa stroke and magnetic resonance imaging examination within 24 h after symptom onset. Infarcts were classified as belonging to a proximal, middle or distal territory location in the posterior fossa. Good outcome was defined as a modified Rankin scale score of ≤1 at 3 months. RESULTS: The largest lesion volumes on diffusion-weighted imaging on day 0 and fluid attenuation inversion recovery (FLAIR) on day 6 were found in the middle territory location with a median volume of 0.4 mL on diffusion-weighted imaging and 1.0 mL on FLAIR on day 6 versus 0.1/0.3 mL in the proximal and 0.1/0.1 mL in the distal territory location of the posterior fossa, respectively. Parameters associated with poor outcome were older age (P = 0.005), higher National Institutes of Health Stroke Scale score on admission/discharge (P = 0.016; P = 0.001), larger lesion volumes on FLAIR on day 6 (P = 0.013) and dysphagia (P = 0.02). There was no significant association between infarct location and modified Rankin scale score on day 90. CONCLUSION: Infarct volume and clinical severity, but not infarct location, were the main contributors to poor long-term outcome in first-ever posterior fossa strokes.

[Prehospital care for stroke patients]. / Prähospitale Versorgung von Patienten mit Schlaganfall.

The effectiveness of thrombolysis or mechanical recanalization for acute stroke is higher, the sooner these therapies are started. Therefore, acute stroke patients need to be evaluated by qualified staff for these therapies as soon as possible. Lay persons need to identify the typical symptoms of stroke as an emergency and act accordingly by calling the emergency medical system (EMS). The EMS team reassesses the symptoms and prompts cerebral imaging. Cerebral imaging is performed ideally in hospitals with a stroke unit where subsequent (stroke) treatments occur. On the way, the emergency team will measure and stabilize vital functions and obtain further important clinical information. Telemedicine allows communicating exact time of onset and severity of symptoms, as well as comorbidities and medication of the patient to the respective hospital. Thereby, the intrahospital workload will be disencumbered and accelerated. Some EMS vehicles now carry point-of-care laboratories and may measure lab values en route (glucose and INR [International Normalized Ratio] for example). Some ambulances are not only equipped with qualified staff, telemedicine technique, and point-of-care labs but even computer tomography (CT) to perform imaging. Such mobile stroke emergency mobiles (STEMO) or mobile stroke units may perform thrombolysis prehospitally. Prehospital thrombolysis has been proven to be initiated faster and is safe. Preliminary results even suggest superiority to intrahospital thrombolysis with respect to clinical outcome. Moreover, STEMO may perform CT-angiography and assess intracranial large-vessel status. If intracranial large-vessel occlusion is present, patients will be brought directly to hospitals able to perform mechanical recanalization. Thus, secondary transports are no longer required.

[Troponin elevation in ischemic stroke patients]. / Troponinerhöhung nach ischämischem Schlaganfall.

Cerebrovascular and cardiovascular diseases are major causes of death and disability worldwide. Ischemic stroke is a frequent complication in cardiac diseases and, vice versa, cardiac complications commonly cause early clinical worsening and death after stroke. In the emergency setting, cardiac biomarkers (preferably troponin, cTn) are measured frequently in patients presenting with acute ischemic stroke. The measurement of cTn is recommended by the guidelines for early management of patients with acute ischemic stroke from the American Heart Association. In case of pathologic cTn elevation, physicians are confronted with diagnostic and therapeutic uncertainties. Up-to-date recommendations on interpretation and consecutive actions remain ambiguous because cTn elevations may originate from causes other than acute coronary disease and because clinical signs and symptoms of acute coronary disease may be obscured by neurological deficits of the stroke. The application of modern, high-sensitive cTn assays that detect even minor cTn elevations has rather aggravated the dilemma of how to interpret this finding in patients with ischemic stroke.This article gives an overview on possible mechanisms of the frequently observed cTn elevation in ischemic stroke patients and offers help on interpretation and meaningful actions.

Impact of heart rate on admission on mortality and morbidity in acute ischaemic stroke patients - results from VISTA.

BACKGROUND AND PURPOSE: Elevated heart rate (HR) is associated with worse outcomes in patients with cardiovascular disease. Its predictive value in acute stroke patients is less well established. We investigated the effects of HR on admission in acute ischaemic stroke patients. METHODS: Using the Virtual International Stroke Trials Archive (VISTA) database, the association between HR in acute stroke patients without atrial fibrillation and the pre-defined composite end-point of (recurrent) ischaemic stroke, transient ischaemic attack (TIA), myocardial infarction (MI) and vascular death within 90 days was analysed. Pre-defined secondary outcomes were the composite end-point components and any death, decompensated heart failure and degree of functional dependence according to the modified Rankin Scale after 90 days. HR was analysed as a categorical variable (quartiles). RESULTS: In all, 5606 patients were available for analysis (mean National Institutes of Health Stroke Scale 13; mean age 67 years; mean HR 77 bpm; 44% female) amongst whom the composite end-point occurred in 620 patients (11.1%). Higher HR was not associated with the composite end-point. The frequencies of secondary outcomes were 3.2% recurrent stroke (n = 179), 0.6% TIA (n = 35), 1.8% MI (n = 100), 6.8% vascular death (n = 384), 15.0% any death (n = 841) and 2.2% decompensated heart failure (n = 124). Patients in the highest quartile (HR> 86 bpm) were at increased risk for any death [adjusted hazard ratio (95% confidence interval) 1.40 (1.11-1.75)], decompensated heart failure [adjusted hazard ratio 2.20 (1.11-4.37)] and worse modified Rankin Scale [adjusted odds ratio 1.29 (1.14-1.52)]. CONCLUSIONS: In acute stroke patients, higher HR (>86 bpm) is linked to mortality, heart failure and higher degree of dependence after 90 days but not to recurrent stroke, TIA or MI.

Hyperintense Vessels on FLAIR: Hemodynamic Correlates and Response to Thrombolysis.

BACKGROUND AND PURPOSE: Hyperintense vessels on baseline FLAIR MR imaging of patients with ischemic stroke have been linked to leptomeningeal collateralization, yet the ability of these to maintain viable ischemic tissue remains unclear. We investigated whether hyperintense vessels on FLAIR are associated with the severity of hypoperfusion and response to thrombolysis in patients treated with intravenous tissue-plasminogen activator. MATERIALS AND METHODS: Consecutive patients with ischemic stroke with an MR imaging before and within 24 hours of treatment, with proved vessel occlusion and available time-to-maximum maps were included (n = 62). The severity of hypoperfusion was characterized on the basis of the hypoperfusion intensity ratio (volume with severe/mild hypoperfusion [time-to-maximum ≥ 8 seconds / time-to-maximum ≥ 2 seconds]). The hypoperfusion intensity ratio was dichotomized at the median to differentiate moderate (hypoperfusion intensity ratio ≤ 0.447) and severe (hypoperfusion intensity ratio > 0.447) hypoperfusion. Good outcome was defined as a modified Rankin Scale score of ≤2. RESULTS: Hyperintense vessels on FLAIR were identified in 54 patients (87%). Patients with extensive hyperintense vessels on FLAIR (>4 sections) had higher NIHSS scores, larger baseline lesion volumes, higher rates of perfusion-diffusion mismatch, and more severe hypoperfusion (hypoperfusion intensity ratio). In stepwise backward multivariate regression analysis for the dichotomized hypoperfusion intensity ratio (including stroke etiology, age, perfusion deficit, baseline lesion volume, smoking, and extent of hyperintense vessels on FLAIR), extensive hyperintense vessels on FLAIR were independently associated with severe hypoperfusion (OR, 6.8; 95% CI, 1.1-42.7; P = .04). The hypoperfusion intensity ratio was an independent predictor of a worse functional outcome at 3 months poststroke (OR, 0.2; 95% CI, 0.5-0.6; P < .01). CONCLUSIONS: Hyperintense vessels on FLAIR are associated with larger perfusion deficits, larger infarct growth, and more severe hypoperfusion, suggesting that hyperintense vessels on FLAIR most likely indicate severe ischemia as a result of insufficient collateralization.

Early infarct FLAIR hyperintensity is associated with increased hemorrhagic transformation after thrombolysis.

BACKGROUND AND PURPOSE: Absence of FLAIR hyperintensity within an acute infarct is associated with stroke onset <4.5 h. However, some patients rapidly develop FLAIR hyperintensity within this timeframe. We hypothesized that development of early infarct FLAIR hyperintensity would predict hemorrhagic transformation (HT) in patients treated with tissue plasminogen activator (tPA) < 4.5 h after onset. METHODS: Consecutive acute stroke patients treated with intravenous tPA <4.5 h after onset who had MRI before and 1 day after thrombolysis were included. Two raters (blind to HT) independently identified FLAIR hyperintensity with reference to the diffusion-weighted image (DWI) lesion. HT was assessed using T2* MRI at 24 h. Hemorrhagic infarction (HI) was defined as petechial HT without mass effect, and parenchymal hematoma (PH) as HT with mass effect. Multivariable logistic regression analysis for HT included FLAIR status, baseline National Institutes of Health Stroke Scale and DWI lesion volume, leukoaraiosis (Wahlund score), serum glucose and reperfusion. RESULTS: Of 109 patients, 33 (30%) had acute FLAIR hyperintensity. HT occurred in 17 patients (15.6%; 15 HI, 2 PH). HT was more common in FLAIR-positive patients than FLAIR-negative patients (33.3% vs. 9.2%, P = 0.009). Median time-to-scan and median time-to-thrombolysis did not differ significantly between patients with HT and without [97 IQR(68, 155) vs. 90 IQR(73, 119), P = 0.5; 120 IQR(99, 185) vs. 125 IQR(95, 150), P = 0.6, respectively]. In multivariable analysis, only FLAIR hyperintensity was independently associated with HT after thrombolysis (OR 18; 95% CI 2-175, P = 0.013). CONCLUSIONS: Early development of FLAIR hyperintensity within the area of diffusion restriction is associated with increased risk of HT after thrombolysis in acute stroke patients.

Levetiracetam in patients with central neuropathic post-stroke pain--a randomized, double-blind, placebo-controlled trial.

BACKGROUND AND PURPOSE: Central post-stroke pain (CPSP) is a severe chronic neuropathic pain condition defined as a spontaneous pain or allodynia corresponding to a vascular lesion. It usually evolves weeks after stroke, and can distinctively impair the quality of life. Treatment is complex and mostly unsatisfactory. We hypothesized that the anti-epileptic drug levetiracetam (LEV) improves CPSP compared with placebo. The purpose of this study was to examine the efficacy and tolerability of LEV in patients with CPSP. METHODS: In a double-blind, placebo-controlled, crossover study design patients with CPSP lasting at least 3 months and a pain score ≥ 4 on the 11-point Likert scale were treated over two 8-week periods with a maximum dose up to 3000 mg LEV or placebo. Primary endpoint was a median pain lowering ≥ 2 in the final treatment week compared with the last baseline week. Secondary outcome measures comprised additional pain ratings, depression, sleep quality, quality of life and patients' global impression of change. RESULTS: Of 42 patients, 33 [61.5 years (40-76); 38% women] completed the study. Side effects and withdrawals were more frequent in the LEV (n = 5) group than in the placebo group (n = 1). Patients treated with LEV did not show any improvement of pain or changes in secondary outcome parameters compared with placebo. CONCLUSIONS: LEV is not effective in treatment for CPSP. The mode of action of LEV does not exert an analgesic effect in chronic CPSP.

[Management of acute ischemic stroke]. / Akutversorgung des ischämischen Schlaganfalls.

The management of acute ischemic stroke aims to verify the clinical diagnosis, to start general supportive care and to enable decision-making about specific forms of therapy.The risk-benefit ratio is time-dependent for many therapeutic options; therefore time delays are a disadvantage within the rescue chain. The trained and multidisciplinary team of the stroke unit forms the backbone of acute management. In addition, technical infrastructure influences therapeutic options and cerebral imaging is the cornerstone.The following four therapies are evidence-based: treatment on a stroke unit, thrombolysis, early administration of acetylsalicylic acid (ASS) and hemicraniectomy in patients younger than 60 years with a so-called malignant infarction.This article describes the necessary diagnostic steps and the general and specific therapeutic options that comprise acute management within the first 48 h.

MRI-based intravenous thrombolysis in stroke patients with unknown time of symptom onset.

BACKGROUND: Currently, stroke patients with unknown time of symptom onset (UTOS) are excluded from therapy with intravenous tissue Plasminogen Activator. We hypothesized that MRI-based intravenous thrombolysis is safe in UTOS. METHODS: We analyzed radiological and clinical data as well as outcomes of stroke patients (including UTOS) who received intravenous thrombolytic therapy after MRI. RESULTS: Compared to patients with known time of symptom onset (n=131), UTOS (n=17) were older (81, 71-88 vs. 75 years, 66-82, P=0.03), had a longer median time between last-seen-well and thrombolysis (12.3 h, IQR 11.5-15.2 h vs. 2.1 h, 1.8-2.8 h, P<0.01), had a longer median door-to-needle time (86 min, 49-112 vs. 60 min, 49-76, P=0.02), and a higher rate of arterial obstruction on MR-angiography (82.4% vs. 56.5%, P=0.04). No symptomatic intracerebral hemorrhage occurred in UTOS. After 3 months, there was no significant difference between groups concerning good functional outcome (modified Rankin Scale 0-2; 35.3% vs. 49.6%, P=0.26) or mortality (0% vs. 15.3%, P=0.08). In multivariate analyses including age, gender, baseline NIHSS, and atrial fibrillation UTOS did not have an independent effect on good functional outcome after 3 months (OR 1.16; 0.32-4.12, P=0.81). CONCLUSIONS: Thrombolysis after MRI seems safe and effective in UTOS. This observation may encourage those who plan prospective placebo-controlled trials of thrombolytics in this subgroup of stroke patients.

Factors influencing in-hospital mortality and morbidity in patients treated on a stroke unit.

OBJECTIVE: To determine the extent that demographics, clinical characteristics, comorbidities, and complications contribute to the risk of in-hospital mortality and morbidity in acute stroke. METHODS: Data of consecutive patients admitted to 14 stroke units cooperating within the Berlin Stroke Register were analyzed. The association of demographics, clinical characteristics, comorbidities, and complications with the risk of in-hospital death and poor outcome at discharge was assessed, and independent attributable risks were calculated, applying average sequential attributable fractions. RESULTS: In a 3-year period, 16,518 consecutive patients with ischemic or hemorrhagic stroke were documented. In-hospital mortality was 5.4%, and 45.7% had a poor outcome (modifed Rankin Scale score ≥3). In patients with length of stay (LOS) ≤7 days, 37.5% of in-hospital deaths were attributed to stroke severity, 23.1% to sociodemographics (age and prestroke disability), and 28.9% to increased intracranial pressure (iICP) and other complications. In those with LOS >7 days, age and stroke severity accounted for 44.1%, whereas pneumonia (12.2%), other complications (12.6%), and iICP (8.3%) contributed to one-third of in-hospital deaths. For poor outcome, attributable risks were similar for prestroke disability, stroke severity, pneumonia, and other complications regardless of the patient's LOS. CONCLUSIONS: Approximately two-thirds of early death and poor outcome in acute stroke is attributed to nonmodifiable predictors, whereas main modifiable factors are early complications such as iICP, pneumonia, or other complications, on which stroke unit treatment should focus to further improve the prognosis of acute stroke.

[Vascular syndromes of the thalamus]. / Vaskuläre Syndrome des Thalamus.

The thalamus comprises numerous nuclei that can be grouped into five major functional domains: (1) the reticular and intralaminar nuclei influence arousal and nociception, (2) sensory nuclei handle afferent pathways, (3) the effector nuclei are involved in motor function and language, (4) associative nuclei participate in higher cognitive functions and (5) limbic nuclei influence mood and motivation. The thalamic nuclei are mainly supplied by the following four cerebral arteries: paramedian artery, anterior thalamoperforating artery, thalamogeniculate artery and posterior choroidal artery (lateral branches). Occlusions of these arteries affect the thalamic nuclei to varying degrees and produce partly characteristic and partly overlapping deficits. This article describes the clinical pictures.

[The German version of the satisfaction with stroke care questionnaire (SASC) for stroke patients]. / Entwicklung der deutschen Version der Patientenzufriedenheits-Skala (SASC) für den Einsatz bei Patienten nach Schlaganfall.

BACKGROUND AND PURPOSE: Patient satisfaction is an important objective to achieve in all parts of the health-care system. Patient satisfaction probably effects adherence to therapy. Until now, German-speaking countries were lacking a reliable instrument to investigate patient satisfaction. The aim of this study was to translate the English Satisfaction with Stroke Care Questionnaire (SASC), validated and created specifically for patients who had a stroke, and to assess the test-retest reliability of the German version. METHODS: The translation of the satisfaction questionnaire followed the protocol of the Medical Outcome Trust. The validation was carried out with continuously admitted inpatients who had suffered an acute stroke and were able to give written consent. Patients received two questionnaires for self-administration three months after hospital admission. The two questionnaires were compared for test-retest reliability. Reliability was measured using AC 1 values. RESULTS: Out of 202 patients continuously admitted to our hospital with the diagnosis of stroke, 33 could not give written informed consent due to aphasia (N = 29) or foreign-language (N = 4) or refused written consent (N = 8) or died during the following 3 months after the event (N = 14). Recall rate at three months was 71 % with 104 of the remaining 147 patients sending both questionnaires back. (Characteristics of responders: NIHSS = 3 [0 - 26], age = 71.5 [31 - 89] years, 40 % female, 48 % with five or more years of secondary school, 66 % paretic, 17 % with aphasia, 26 % with atrial fibrillation). The test-retest reliability of the German version of the self-administered satisfaction questionnaire was substantial (mean AC 1 = 0.612; range from 0.307 to 0.789). CONCLUSION: The German version of the SASC is a reliable tool to test patient satisfaction in stroke patients in the German language.

Vascular risk factor awareness before and pharmacological treatment before and after stroke and TIA.

BACKGROUND AND PURPOSE: Educating the public to screen for vascular risk factors and have them treated is a major public health issue. We assessed the vascular risk factor awareness and frequency of treatment in a cohort of patients with cerebral ischaemia. METHODS: Data on awareness and pharmacological treatment of vascular risk factors before hospital admission of patients with confirmed ischaemic stroke/transient ischaemic attack (TIA) were analyzed. A follow-up questionnaire assessed the frequency of treatment 1 year after discharge and assessed non-adherence to antithrombotic medication. RESULTS: At time of stroke/TIA, individual awareness regarding existing hypertension, diabetes, hyperlipidemia and atrial fibrillation (AF) was 83%, 87%, 73% and 69% respectively (n = 558). Pharmacological treatment for hypertension, diabetes, hyperlipidemia and AF was being administered in 80%, 77%, 37% and 62% of patients aware of their conditions. The follow-up was completed by 383 patients (80% recall rate): of the patients with hypertension, diabetes, hyperlipidemia and AF, 89%, 78%, 45% and 86% were receiving risk factor targeted medication. This represents a significant increase concerning AF and hyperlipidemia. Non-adherence to recommended antithrombotics (15%) was higher in patients who had had a TIA. CONCLUSIONS: All risk factors leave room for improvement in screening and treatment efforts. Adherence to treatment is higher for hypertension and diabetes than for hyperlipidemia. Education efforts should bear in mind less well recognized risk factors.
