Long-Term Incidence of Ischemic Stroke After Transient Ischemic Attack: A Nationwide Study From 2014 to 2020.

BACKGROUND: The short-term incidence of ischemic stroke after a transient ischemic attack (TIA) is high. However, data on the long-term incidence are not well known but are needed to guide preventive strategies. METHODS: Patients with first-time TIA (index date) in the Danish Stroke Registry (January 2014-December 2020) were included and matched 1:4 with individuals from the background population and 1:1 with patients with a first-time ischemic stroke on the basis of age, sex, and calendar year. The incidences of ischemic stroke and mortality from index date were estimated by Aalen-Johansen and Kaplan-Meier estimators, respectively, and compared between groups using multivariable Cox regression. RESULTS: We included 21 500 patients with TIA, 86 000 patients from the background population, and 21 500 patients with ischemic stroke (median age, 70.8 years [25th-75th percentile, 60.8-78.7]; 53.1% males). Patients with TIA had more comorbidities than the background population, yet less than the control stroke population. The 5-year incidence of ischemic stroke after TIA (6.1% [95% CI, 5.7-6.5]) was higher than the background population (1.5% [95% CI, 1.4-1.6], P<0.01; hazard ratio, 5.14 [95% CI, 4.65-5.69]) but lower than the control stroke population (8.9% [95% CI, 8.4-9.4], P<0.01; hazard ratio, 0.58 [95% CI, 0.53-0.64]). The 5-year mortality for patients with TIA (18.6% [95% CI, 17.9-19.3]) was higher than the background population (14.8% [95% CI, 14.5-15.1], P<0.01; hazard ratio, 1.26 [95% CI, 1.20-1.32]) but lower than the control stroke population (30.1% [95% CI, 29.3-30.9], P<0.01; hazard ratio, 0.41 [95% CI, 0.39-0.44]). CONCLUSIONS: Patients with first-time TIA had an ischemic stroke incidence of 6.1% during the 5-year follow-up period. After adjustment for relevant comorbidities, this incidence was approximately 5-fold higher than what was found for controls in the background population and 40% lower than for patients with recurrent ischemic stroke.

Vascular neuro-otology: vestibular transient ischemic attacks and chronic dizziness in the elderly.

PURPOSE OF REVIEW: To explore the differential diagnosis of posterior fossa transient ischemic attacks (TIA) associated with vertigo and/or imbalance.To review the contribution of cerebral small vessel (SVD) disease to balance dysfunction and dizziness in the elderly. MAIN FINDINGS: TIAs involving vestibular structures that mediate the vestibulo-ocular and vestibulospinal reflexes remain a diagnostic challenge because they overlap with causes of benign episodic vertigo. Here, we summarize the results of multidisciplinary specialty efforts to improve timely recognition and intervention of peripheral and central vestibular ischemia. More papers confirm that SVD is a major cause of gait disability, falls and cognitive disorder in the elderly. Recent work shows that early stages of SVD may also be responsible for dizziness in the elderly. The predominant location of the white matter changes, in the frontal deep white matter and genu of the corpus callosum, explains the association between cognitive and balance dysfunction in SVD related symptoms. SUMMARY: The evaluation of patients with intermittent vascular vertigo represent a major diagnostic challenge, recent reviews explore the ideal design approach for a multidisciplinary study to increase early recognition and intervention. Hemispheric white matter microvascular ischemia has been the subject of research progress - advanced stages are known to cause gait disorder and dementia but early stages are associated with "idiopathic" dizziness in the elderly.

Effect of Mobile Stroke Unit Dispatch in all Patients with Acute Stroke or TIA.

OBJECTIVE: To determine the effect of additional mobile stroke unit (MSU) dispatch on functional outcomes among the full spectrum of stroke patients, regardless of subtype or potential contraindications to reperfusion therapies. METHODS: We used data from the nonrandomized Berlin-based B_PROUD study (02/2017 to 05/2019), in which MSUs were dispatched based solely on availability, and the linked B-SPATIAL stroke registry. All patients with final stroke or transient ischemic attack (TIA) diagnoses were eligible. The intervention under study was the additional dispatch of an MSU, an emergency physician-staffed ambulance equipped to provide prehospital imaging and thrombolytic treatment, compared to conventional ambulance alone. The primary outcome was the 3-month modified Rankin Scale (mRS) score, and the co-primary outcome was a 3-tiered disability scale. We identified confounders using directed acyclic graphs and obtained adjusted effect estimates using inverse probability of treatment weighting. RESULTS: MSUs were dispatched to 1,125 patients (mean age: 74 years, 46.5% female), while for 1,141 patients only conventional ambulances were dispatched (75 years, 49.9% female). After confounding adjustment, MSU dispatch was associated with more favorable 3-month mRS scores (common odds ratio [cOR] = 0.82; 95% confidence interval [CI]: 0.71-0.94). No statistically significant association was found with the co-primary outcome (cOR = 0.86; 9% CI: 0.72-1.01) or 7-day mortality (OR = 0.94; 95% CI: 0.59-1.48). INTERPRETATION: When considering the entire population of stroke/TIA patients, MSU dispatch improved 3-month functional outcomes without evidence of compromised safety. Our results are relevant for decision-makers since stroke subtype and treatment eligibility are unknown at time of dispatch. ANN NEUROL 2023;93:50-63.

Smokers with Elevated Glycated Albumin Could Not Benefit from Dual Antiplatelet Therapy after Minor Stroke or Transient Ischemic Attack.

INTRODUCTION: The aim of this study was to investigate the impact of smoking on dual antiplatelet therapy in patients with minor stroke or transient ischemic attack (TIA) under different glycated albumin (GA) levels. METHODS: We analyzed data from the Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events (CHANCE) trial. A subgroup of 3,044 patients with baseline GA levels was included and categorized by smoking status and GA levels. The primary efficacy outcome was a new stroke within 90 days. The safety outcome was any bleeding event at 90 days. The interaction of smoking status with antiplatelet therapy was calculated by Cox proportional hazards regression model. RESULTS: In patients with GA levels ≤15.5%, the proportion of smokers was 37.7% (719/1,908), while in patients with GA levels >15.5%, it was 51.6% (586/1,136). During the 3-month follow-up period, 299 (9.9%) patients had a new stroke occurrence. In patients with elevated GA levels, both smokers and nonsmokers could not benefit from dual antiplatelet therapy (smokers, adjusted hazard ratio [HR] 0.70, 95% confidence interval [CI]: 0.42-1.17; nonsmokers, adjusted HR 0.82, 95% CI: 0.57-1.18). In patients with normal GA levels, dual antiplatelet therapy reduced the risk of stroke recurrence in smokers by 72% (adjusted HR 0.28, 95% CI: 0.14-0.56) and in nonsmokers by 53% (adjusted HR 0.47, 95% CI: 0.26-0.86). However, whether the GA level was elevated or normal, there was no significant interaction between smoking status and antiplatelet therapy. CONCLUSIONS: Smokers with elevated GA levels could not benefit from dual antiplatelet therapy after minor stroke or TIA.

Large variations in atrial fibrillation screening practice after ischemic stroke and transient ischemic attack in Sweden: a survey study.

BACKGROUND: Atrial fibrillation (AF) screening after ischemic stroke or transient ischemic attack (TIA) is given high priority in clinical guidelines. However, patient selection, electrocardiogram (ECG) modality and screening duration remains undecided and current recommendations vary. METHODS: The aim of this study was to investigate the clinical practice of AF screening after ischemic stroke or TIA at Swedish stroke units. In collaboration with the stakeholders of the Swedish Stroke Register (Riksstroke) a digital survey was drafted, then tested and revised by three stroke consultants. The survey consisted of 17 multiple choice/ free text questions and was sent by e-mail to the medical directors at all stroke units in Sweden. RESULTS: All 72 stroke units in Sweden responded to the survey. Most stroke units reported that ≥ 75% of ischemic stroke (69/72 stroke units) or TIA patients (67/72 stroke units), without previously known AF, were screened for AF. Inpatient telemetry ECG was the method of first-choice in 81% of the units, but 7% reported lack of access. A variety of standard monitoring durations were used for inpatient telemetry ECG. The second most common choice was Holter ECG (17%), also with considerable variations in monitoring duration. Other AF screening modalities were used as a first-choice method (handheld and patch ECG) but less frequently. CONCLUSIONS: Clinical practice for AF screening after ischemic stroke or TIA differed between Swedish stroke units, both in choice of AF screening methods as well as in monitoring durations. There is an urgent need for evidence and evidence-based recommendations in this field. TRIAL REGISTRATION: Not applicable.

Asymmetric and symmetric dimethylarginine as markers of endothelial dysfunction in cerebrovascular disease: A prospective study.

BACKGROUND AND AIM: Asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) have been proposed as mediators of endothelial dysfunction. In this study, we aimed to investigate the diagnostic and prognostic role of ADMA and SDMA in acute cerebrovascular disease. METHODS AND RESULTS: A prospective case-control study was performed, enrolling 48 patients affected by ischemic stroke with no cardioembolic origin, 20 patients affected by TIA, 40 subjects at high cardiovascular risk and 68 healthy subjects. ADMA levels were significantly lower in high-risk subjects (18.85 [11.78-22.83] µmol/L) than in patients with brain ischemic event, both transient (25.70 [13.15-40.20] µmol/L; p = 0.032) and permanent (24.50 [18.0-41.33] µmol/L; p = 0.001). SDMA levels were different not only between high-risk subjects and ischemic patients, but also between TIA and stroke patients, reaching higher levels in TIA group and lower levels in stroke group (1.15 [0.90-2.0] vs 0.68 [0.30-1.07] µmol/L; p < 0.001). SDMA was also correlated with short-term prognosis, with lower levels in case of adverse clinical course, evaluated by type of discharge (p = 0.009) and need of prolonged rehabilitation (p = 0.042). CONCLUSIONS: The present study highlights the relationship between l-arginine, ADMA, SDMA and acute cerebrovascular events. Therefore, our results suggested a potential role of SDMA as a specific marker of transient ischemic damage and as a short-term positive prognostic marker.

Long-term risk factors of recurrent stroke, myocardial infarction and death in patients leaving hospital with a diagnosis of ischemic stroke or TIA.

Objectives. The prevalence of patients with prior stroke is increasing globally. Accordingly, there is a need for up-to-date evidence of patient-related prognostic factors for stroke recurrence, post stroke myocardial infarction (MI) and death based on long-term follow-up of stroke survivors. For this purpose, the RIALTO study was established in 2004. Design. A prospective cohort study in which patients diagnosed with ischemic stroke (IS) or transient ischemic attack (TIA) in three Copenhagen hospitals were included. Data were collected from medical records and by structured interview. Data on first stroke recurrence, first MI and all-cause death were extracted from the Danish National Patient Registry and the Danish Civil Registration System. Results. We included 1215 patients discharged after IS or TIA who were followed up by register data from April 2004 to end of 2018 giving a median follow-up of 3.5-6.9 years depending on the outcome. At the end of follow-up 406 (33%) patients had been admitted with a recurrent stroke, 100 (8%) had a MI and 822 (68%) had died. Long-term prognostic predictors included body mass index, diabetes, antihypertensive and lipid lowering treatment, smoking, a sedentary lifestyle as well as poor self-rated health and psychosocial problems. Conclusions. Long-term risk of recurrent stroke and MI remain high in patients discharged with IS or TIA despite substantial improvements in tertiary preventive care in recent decades. Continued attention to the patient risk profile among patients surviving the early phase of stroke, including comorbidities, lifestyle, and psychosocial challenges, is warranted.

Effects of a 1 year aerobic and strength training on cognitive functioning after transient ischemic attack or minor stroke: A randomized controlled trial.

OBJECTIVES: Patients who have recently suffered a transient ischemic attack (TIA) or minor ischemic stroke are at increased risk of cognitive impairment. In the present study, we aimed to investigate the effect of a 1-year exercise intervention on cognitive functioning up to 2 years post intervention. MATERIAL AND METHODS: We conducted a single-blind randomized controlled trial to investigate the effect of an exercise intervention on cognitive functioning, compared with usual care, for up to 2 years. Patients with a TIA or minor stroke were randomly allocated to an intervention group receiving the 1-year exercise intervention (n = 60) or to usual care (n = 59). Outcome measures were assessed at baseline and after 1 and 2 years. We measured cognition with neuropsychological tests on three domains: (1) executive functioning, (2) attention-psychomotor speed, and (3) memory. Linear mixed models were used for longitudinal data to determine the effect of the exercise intervention on cognitive functioning. Statistical analyses were performed using IBM SPSS software 24.0. RESULTS: We found that over the two years study period -and corrected for age, sex, and educational level- the intervention group on average improved significantly more in executive functioning than the control group (ß = 0.13; 95 % CI [0.02 to 0.25]; p = 0.03). No significant intervention effects were found on either memory or attention-psychomotor speed. CONCLUSIONS: Our data show that a 1-year exercise intervention significantly improved executive functioning over time, compared to usual care. We recommend that health care professionals consider broadening standard secondary stroke prevention treatment in patients with TIA/minor stroke by adding exercise and physical activity.

Predictors of post stroke cognitive impairment: VITATOPS cognition substudy.

INTRODUCTION: Post stroke cognitive impairment (PSCI) is a common complication of ischemic stroke. PSCI can involve different depending on clinical and stroke related characteristics. The aim of this study is to determine the factors associated with impairments in specific cognitive domains. METHODS: The Vitamins to Prevent Stroke (VITATOPS) trial is a large, multinational randomised controlled trial. In this substudy, consecutive patients admitted for ischaemic stroke or transient ischaemic attack (TIA) at a tertiary hospital in Singapore were included. PSCI was defined as impairment of any of the six cognitive subgroups - visuoconstruction, attention, verbal memory, language, visual memory and visuomotor function - that were assessed annually for up to five years. Univariate and multivariate Cox proportional hazard models were used to determine factors associated with impairments in each of these cognitive domains. RESULTS: A total of 736 patients were included in this study, of which 173 (23.5 %) developed cognitive impairment. Out of the six cognitive domains, the greatest proportion of patients had an impairment in visuoconstruction (26.4 %) followed by attention (19.8 %), verbal memory (18.3 %), language (17.5 %), visual memory (17.3 %) and visuomotor function (14.8 %). Patients with posterior circulation cerebral infarction (POCI) as the index stroke subtype had higher rates of cognitive impairment. Further subgroup analyses show that Indian race and advanced age were predictive of language impairment, whilst fewer years of education and POCI were predictive of verbal memory impairment. POCI was predictive of visual memory impairment, and advanced age and POCI were predictive of visuomotor function impairment. CONCLUSION: We identified visuoconstruction and attention domains to be the most affected in our Asian cohort of PSCI. Advanced age, lower levels of education, posterior circulation strokes and concomitant comorbidities such as peripheral artery disease are independent predictors of PSCI.

Medium-intensity statin with ezetimibe versus high-intensity statin in acute ischemic cerebrovascular disease (MESIA): A randomized clinical trial.

BACKGROUND: High-risk stroke patients are recommended to receive high-intensity statin therapy to reduce the risk of stroke recurrence. However, doubling the dosage of statin drugs did not increase the achievement rate of LDL-C target or provide additional clinical benefits, but significantly increased the risk of adverse reactions. Statins and ezetimibe work through different mechanisms and the combined use of statins and ezetimibe significantly improves outcomes with comparable safety profiles. We tested the hypothesis that moderate-intensity statin with ezetimibe may offer advantages over the conventional high-intensity statin regimen in terms of efficacy and safety. METHODS: We conducted a randomized controlled trial. Eligible participants were aged 18 years or older with acute ischemic cerebrovascular disease. We randomly assigned (1:1) participants within the acute phase of ischemic stroke, i.e., within 1 week after the onset of mild ischemic stroke (NIHSS score ≤ 5), within 1 month for severe cases (NIHSS score ≥ 16), and within 2 weeks for the rest, as well as patients with TIA within 1 week of symptom onset, to receive either moderate-intensity statin with ezetimibe (either 10-20 mg atorvastatin calcium tablets plus a 10 mg ezetimibe tablet, or 5-10 mg rosuvastatin calcium tablets once per day plus a 10 mg ezetimibe tablet once per day) or high-intensity statin (40 mg atorvastatin calcium tablets or 20 mg rosuvastatin calcium tablets once per day) for 3 months. Randomization was performed using a random number table method. The primary efficacy outcome was the level and achievement rate of LDL-C after 3 months of treatment, specifically LDL-C ≤ 1.8 mmol/L or a reduction in LDL-C ≥ 50 %. The secondary outcome was the incidence of new stroke or transient ischemic attack (TIA) within 3 months. The safety outcome was liver and renal function tests, and the occurrence of statin-related muscle events within 3 months. FINDINGS: This trial took place between March 15, 2022, and March 7, 2023. Among 382 patients screened, 150 patients were randomly assigned to receive either medium-intensity statins with ezetimibe (n = 75) or high-intensity statins (n = 75). Median age was 60.0 years (IQR 52.75-70.25); 49 (36.6 %) were women and 85 (63.4 %) were men. The target achievement of LDL-C at 3 months occurred in 62 (89.86 %) of 69 patients in the medium-intensity statin with ezetimibe group and 46 (70.77 %) of 65 patients in the high-intensity statin group (P=0.005, OR=0.273, 95 % CI: 0.106, 0.705). The reduction magnitude of LDL-C in moderate-intensity statin with ezetimibe group was significantly higher (-56.540 % vs -47.995 %, P=0.001). Moderate-intensity statin with ezetimibe group showing a trend of a greater reduction in LDL-C absolute value than high-intensity statin group but without statistical significance (-1.77±0.90 vs -1.50±0.89, P=0.077). New AIS or TIA within 3 months, liver and renal function tests, and the occurrence of statin-related muscle events within 3 months were also statistically insignificant. Multivariate logistic regression analysis showed that both gender and lipid-lowering regimen as independent risk factors influencing the rate of LDL-C achievement in individuals diagnosed with acute ischemic cerebrovascular disease, but only lipid-lowering regimen had predictive value. INTERPRETATION: Compared to guideline-recommended high-intensity statin therapy, moderate-intensity statin with ezetimibe further improved the achievement rate of LDL-C in patients with acute ischemic cerebrovascular disease, with a higher reduction magnitude in LDL-C. In terms of safety, there was no significant difference between the two regimens, suggesting that moderate-intensity statin with ezetimibe can also be considered as an initial treatment option for patients with acute ischemic cerebrovascular disease.

Predictors of recurrent cerebral ischemia after patent foramen ovale closure: A single center observational study.

OBJECTIVES: Transcatheter patent foramen ovale closure lowers recurrent stroke in patients with cryptogenic stroke or transient ischemic attack with an indication for closure. However, the incidence of recurrent stroke is not negligible and underlying pathophysiology remains largely unknown. We sought to evaluate the prevalence of recurrent ischemic neurological events and to assess its predictors after transcatheter patent foramen ovale closure. METHODS: We enrolled consecutive patients who underwent patent foramen ovale closure for secondary prevention of neurological ischemic events at the University Hospital of Parma between 2006 and 2021. Clinical and procedure-related features were collected for each patient. The incidence of recurrent ischemic neurological events was assessed at follow-up. RESULTS: We enrolled a total of 169 patients with mean Risk of Paradoxical Embolism score at hospital admission of 6.4 ± 1.5. The primary indication was previous cryptogenic stroke (94 [55.6 %] subjects), followed by transient ischemic attack (75 [44.4 %]). Among patients with complete outcome data (n= 154), after a median follow-up of 112 months, recurrent cerebral ischemia occurred in 13 [8.4 %], with an annualized rate of 0.92/100 patients. The presence of obesity [OR 5.268, p = 0.018], Risk of Paradoxical Embolism score < 7 [OR 5.991, p = 0.035] and migraine [OR = 5.932 p = 0.012] were independent positive predictors of recurrent stroke/ transient ischemic attack after patent foramen ovale closure. CONCLUSIONS: The presence of obesity, Risk of Paradoxical Embolism score < 7 and migraine were independent positive predictors of recurrent ischemic neurological events after patent foramen ovale closure.

Anticoagulants versus Antiplatelet Treatment in the Medical Management of Carotid Floating Thrombus.

BACKGROUND: Carotid free-floating thrombus (CFT) is a rare cause of stroke describing an intraluminal thrombus that is loosely associated with the arterial wall and manifesting as a filling defect fully surrounded by flow on vascular imaging. Unfortunately, there is no clear consensus among experts on the ideal treatment for this pathology. METHODS: Retrospective analysis of acute ischemic stroke (AIS) and transient ischemic attack (TIA) patients diagnosed with CFT on computed tomography angiogram (CTA) between January 2015-March 2023. We aimed to compare two treatment regimens: anticoagulation (ACT) and antiplatelet (APT) in the treatment of CFT. APT regimens included the use of dual or single antiplatelets (DAPT or SAPT; aspirin, clopidogrel and ticagrelor) and ACT regimens included the use of direct oral anticoagulants, warfarin, heparin or low molecular weight heparin +/- ASA. Patients that underwent mechanical thrombectomy were excluded. RESULTS: During study time there were 8252 acute ischemic stroke hospitalizations, of which 135 (1.63 %) patients were diagnosed with CFT. Sixty-six patients were included in our analysis. Patients assigned to APT were older (60.41years ± 12.82;p < 0.01). Other demographic variables were similar between ACT and APT groups. Complete CFT resolution on repeat vascular imaging was numerically higher at 30 days (58.8 vs 31.6 %, respectively; p = 0.1) and at latest follow-up (70.8 vs 50 %; p = 0.1) on ACT vs APT, respectively without reaching statistical significance. Similarly, there was numerically higher rates of any ICH with ACT compared to APT but it did not achieve statistical significance (27.6 % vs 13.5 %; p = 0.5). There were similar rates of PH1/2 hemorrhagic transformation, independence at discharge and similar hospital length of stay between ACT and APT groups. Patients assigned to APT were more likely to be discharged on their assigned treatment compared to those assigned to ACT (86.5 vs 55.2 %; p < 0.001). The rate of 30-day recurrent stroke was comparable among ACT and APT at 30 days (3.4 vs 0 %; p = 0.1, respectively). Subgroup analysis comparing exclusive ACT vs Dual APT lead to similar results. CONCLUSION: Our study showed comparable efficacy and safety outcomes in CFT patients who were exclusively managed medically with ACT vs APT. Larger prospective studies are needed.

Computed diffusion-weighted imaging in patients with transient neurovascular symptoms with and without ischemic infarction.

PURPOSE: Detection of ischemic lesions in patients with transient neurovascular symptoms is relevant for the estimation of the risk of a subsequent stroke and etiological classification. To improve detection rates, different technical approaches have been used, such as diffusion-weighted imaging (DWI) with high b-values or higher magnetic field strength. Here, we sought to investigate the value of computed DWI (cDWI) with high b-values in these patients. METHODS: From an MRI report database we identified patients with transient neurovascular symptoms who underwent repeated MRI including DWI. cDWI was calculated with a monoexponential model with high b-values (2000, 3000, and 4000 s/mm2) and compared to the routinely used standard DWI with regard to presence of ischemic lesions and lesion detectability. RESULT: Overall 33 patients with transient neurovascular symptoms (71 [IQR 57-83.5] years; 21 [63.6%] male) were included. On DWI, acute ischemic lesions were observed in 22 (78.6%). Acute ischemic lesions were observed in 17 (51.5%) patients on initial DWI, and in 26 (78.8%) patients on follow-up DWI. Lesion detectability was rated significantly better on cDWI at 2000s/mm2 compared to standard DWI. In 2 (9.1%) patients, cDWI at 2000s/mm2 revealed an acute ischemic lesion proven on follow-up standard DWI which was not detected with certainty on the initial standard DWI. CONCLUSION: cDWI might be a valuable addition to routinely acquired standard DWI in patients with transient neurovascular symptoms since its use might result in improved ischemic lesion detection. A b-value of 2000s/mm2 seems most promising for clinical practice.

Transient Ischemic Attack in a 22-Year-Old NCAA Division I Baseball Athlete: A Case Study.

CONTEXT: A healthy, 22-year-old, male NCAA Division I baseball shortstop was experiencing confusion, chest pain, and tightness during an off-season intersquad scrimmage. The patient did not have any significant medical history or mechanism of head injury. After initial evaluation from the athletic trainer, the patient's cognitive status began to quickly decline. The emergency action plan was put in place rapidly and referred the patient to the local emergency clinic. CASE PRESENTATION: Upon arrival at the emergency department, an electrocardiogram was performed to rule out myocardial infarction or stroke. The first electrocardiogram results returned negative for any cardiac pathology, but a stroke alert was called. The patient was then transported to a level II trauma center due to continual cognitive decline. The patient was diagnosed with transient ischemic attack (TIA) secondary to an undiagnosed patent foramen ovale (PFO) that would later be diagnosed with further evaluation 2 months after the initial TIA incident. After multiple diagnostic and laboratory tests, the PFO went undetected until a 2D echocardiogram was performed and evaluated by a cardiologist. MANAGEMENT AND OUTCOMES: After the confirmation of the congenital defect, surgical intervention was performed to correct the PFO using catheterization. Despite multiple preparticipation examinations, electrocardiograms, and examination of past family history, the PFO went undetected until the patient experienced symptoms of TIA. The discovery of PFO in this 22-year-old athletic individual is unusual because traditional screening techniques (electrocardiogram and preparticipation examinations) failed to detect the congenital defect. CONCLUSIONS: Due to the emergent and timely actions of the athletic trainer, the patient has made a full recovery and is able to compete fully in athletic events. This case study amplifies the need for athletic trainers at all sporting events, updated and reviewed emergency action plans, rapid recognition of TIA in athletic individuals, and return-to-play protocol for an athletic individual after TIA.

ASSESSING THE PATIENT WITH ANTIPHOSPHOLIPID SYNDROME IN LIGHT OF THE NEW 2023 ACR/EULAR ANTIPHOSPHOLIPID SYNDROME CLASSIFICATION CRITERIA - CASE REPORT.

Antiphospholipid syndrome (APS) is an acquired multisystem autoimmune disease characterized clinically by vascular thrombotic events, or pregnancy complications or nonthrombotic manifestations in the presence of persistently elevated antiphospholipid antibodies (aPL). We highlighted our case, which fulfills both the old APS classification criteria (1999,2006) _and the newest one (2023). The latest demonstrates very high specificity (99%) for APS diagnosis, compared to the older revised Sapporo criteria (86%). According to the new recommendation, the criteria are classified into 6 clinical and 2 laboratory domains, patient must accumulate at least 3 points from each clinical and laboratory domains. Our patient was diagnosed with antiphospholipid syndrome in 2018, as she had transient ischemic attack (TIA) without any changes on magnetic resonance tomography (MRI), and laboratory tests revealed triple positive antiphospholipid antibodies (12 points). Additional diagnostic tests were performed_thrombocytopenia, aortic valve thickening was noteworthy (4 points). Thus, TIA which had similar strength to stroke as the manifestation of arterial thrombosis by old guidelines, it is rejected according to the new recommendation, so the patient lost minimum 2 points; On the other hand, the current criteria added nonthrombotic events as weighted clinical domains, which gave the points to our patient. In conclusion we fully and highly specifically confirmed APS diagnosis as ACR/EULAR suggests.

Diagnosis, Workup, Risk Reduction of Transient Ischemic Attack in the Emergency Department Setting: A Scientific Statement From the American Heart Association.

At least 240 000 individuals experience a transient ischemic attack each year in the United States. Transient ischemic attack is a strong predictor of subsequent stroke. The 90-day stroke risk after transient ischemic attack can be as high as 17.8%, with almost half occurring within 2 days of the index event. Diagnosing transient ischemic attack can also be challenging given the transitory nature of symptoms, often reassuring neurological examination at the time of evaluation, and lack of confirmatory testing. Limited resources, such as imaging availability and access to specialists, can further exacerbate this challenge. This scientific statement focuses on the correct clinical diagnosis, risk assessment, and management decisions of patients with suspected transient ischemic attack. Identification of high-risk patients can be achieved through use of comprehensive protocols incorporating acute phase imaging of both the brain and cerebral vasculature, thoughtful use of risk stratification scales, and ancillary testing with the ultimate goal of determining who can be safely discharged home from the emergency department versus admitted to the hospital. We discuss various methods for rapid yet comprehensive evaluations, keeping resource-limited sites in mind. In addition, we discuss strategies for secondary prevention of future cerebrovascular events using maximal medical therapy and patient education.

Redefining Disability: Patient-Reported Outcome Measures After Minor Stroke and Transient Ischemic Attack.

BACKGROUND: Long-term outcome assessment patients with stroke is not fully captured by usual clinical scales such as the modified Rankin Scale (mRS). Patient-reported outcome measures (PROMs) are standardized and validated assessments that consider clinical outcomes from the patient perspective. We aim to analyze the added value of PROMs in patients with transient ischemic attack and minor stroke. METHODS: We included consecutive patients with minor stroke or transient ischemic attack (National Institutes of Health Stroke Scale score 0-5) from April 2020 to October 2021 that participated in the PROMs-through-App program (NORA, NoraHealth Barcelona Spain). Clinician and self-evaluated outcomes were assessed at 90 days: clinician-evaluated mRS, self-reported mRS, the 10-item patient-reported outcome measures questionnaire global health survey (v1.2), Hospital Anxiety and Depression Scale, and the Fatigue Assessment Scale. We evaluated the acceptability (response rate), reliability (internal consistency), and construct validity (correlation with mRS and between scales) of each questionnaire. RESULTS: We included 355 patients in the analysis, response rate was patient-reported outcome measures questionnaire 71.3% (253), Hospital Anxiety and Depression Scale 70.7% (251), Fatigue Assessment Scale 71.8% (255), and self-assessed mRS 66.8% (237). PROMS internal consistency was good or excellent, while agreement between clinician and self-reported mRS was fair (k=0.34). Rate of abnormal PROMS scores were as follows (all responders versus clinician-reported mRS score 0-2): patient-reported outcome measures questionnaire mental health (43.1% versus 36.3%), physical health (48.6% versus 43.6%); Hospital Anxiety and Depression Scale-anxiety (21.9% versus 17.7%) and depression (17.1% versus 13.3%); and Fatigue Assessment Scale (40.8% versus 36.4%). PROMs scores correlated with clinician and self-reported mRS at 90 days. CONCLUSIONS: Evaluation of PROMs using a mobile-app-based communication system is a reliable and valid strategy to assess the outcome of patients from their perspective after a mild stroke or transient ischemic attack.

Screening for health-related quality of life and its determinants in Fabry disease: A cross-sectional multicenter study.

BACKGROUND: Fabry disease (FD) is a rare X-linked lysosomal storage disorder caused by α-galactosidase A (α-Gal A) deficiency. The progressive accumulation of globotriaosylceramide results in life-threatening complications, including renal, cardiac, and cerebrovascular diseases. In order to improve health care of FD-patients, knowledge of its predictors is important. The aim of our study was to evaluate health-related quality of life (HrQol) in FD and to identify its independent determinants by exploring a wide range of demographic, social and clinical parameters. RESULTS: In this cross-sectional multicenter study, 135 adult patients with FD were recruited at three specialized European centers in Germany and Switzerland. Demographics, social status and clinical parameters as well as data on HrQol (EQ5D, EQ VAS) and depression were collected by means of self-reporting questionnaires and confirmed by medical records. HrQol and its predictors were evaluated by univariate and multivariate regression analyses. The study population consisted of 78 female and 57 male FD patients (median age 48 yrs) of whom 80.7% (N = 109) were on enzyme replacement therapy (ERT) and 10.4% (N = 14) were on chaperone treatment. Univariate analysis revealed various factors reducing HrQol such as age > 40 years, classic phenotype, organ involvement (kidney and heart disease, stroke/transient ischemic attack (TIA), gastrointestinal disturbances), depression, and burning limb pain. However, only the following factors were identified as independent predictors of decreased HrQol: classic phenotype, kidney and heart disease, stroke/TIA, depression, and burning limb pain. ERT and chaperone therapy were independent determinants of increased HrQol. CONCLUSIONS: Modifiable factors, such as burning limb pain and depression, identified as independent predictors of HrQol-deterioration should be addressed in programs aiming to improve HrQol in FD. A multidisciplinary approach is essential in FD-patients since diverse organ involvement prominently compromises HrQol in affected patients. Our findings showed that the classic phenotype is a strong predictor of worsening HrQol.

Atrial fibrillation detection using insertable cardiac monitor after stroke: A real-world cohort study.

OBJECTIVE: This study aimed to report the real-world atrial fibrillation (AF) diagnostic yield of the implantable cardiac monitor (ICM) in patients with stroke or transient ischemic attack (TIA), and compare it to patients with an ICM for unexplained syncope. METHODS: We used patient data from device clinics across the United States of America with ICM remote monitoring via PaceMate™, implanted for stroke or TIA, and unexplained syncope. Patients with known AF or atrial flutter were excluded. The outcome was AF lasting ≥2 min, adjudicated by International Board of Heart Rhythm Examiners certified cardiac device specialists. RESULTS: We included a total of 2469 patients, 51.1% with stroke or TIA (mean age: 69.7 [SD: 12.2] years, 41.1% female) and 48.9% with syncope (mean age: 67.0 [SD: 17.1] years, 59.4% female). The cumulative AF detection rate in patients with stroke or TIA was 5.5%, 8.9%, and 14.0% at 12, 24, and 36 months, respectively. The median episode duration was 73 (interquartile range: 10-456) min, ranging from 2 min to 40.9 days, with 52.3%, 28.6%, and 4.4% of episodes lasting at least 1, 6, and 24 h, respectively. AF detection was increased by age (adjusted hazard ratio [for every 1-year increase]: 1.024, 95% confidence interval: 1.008-1.040; p = .003), but was not influenced by sex (p = .089). For comparison, the cumulative detection rate at 12, 24, and 36 months were, respectively, 2.4%, 5.2%, and 7.4% in patients with syncope. CONCLUSION: Patients with stroke or TIA have a higher rate of AF detection. However, this real-world study shows significantly lower AF detection rates than what has been previously reported.

Modifiable risk factors for occurrence of ipsilateral ischemic events after carotid endarterectomy beyond perioperative period.

OBJECTIVE: The purpose of this study was to quantify the effects of several modifiable variables on the occurrence of stroke after the initial perioperative period for patients who had undergone carotid endarterectomy (CEA). METHODS: The primary outcome for the present study was the development of an ischemic stroke or transient ischemic attack (TIA) in the cerebral hemisphere ipsilateral to CEA after the initial hospitalization. All CEAs in the VQI between January 2003 and May 2022 were queried. We identified 171,816 CEAs in the database. The exclusion criteria for the study were the lack of follow-up data for >30 days, concomitant coronary artery bypass surgery, concomitant proximal or distal carotid intervention at CEA, other arterial interventions at CEA, and stroke or TIA during the initial hospital admission, leaving 126,290 patients for analysis. We used the χ2 test for statistical analysis of the outcome of ipsilateral ischemic stroke or TIA after the initial CEA hospital admission to determine the relevant variables. Age was evaluated as an ordinal variable using the Student t test. Variables with P ≤ .05 on univariable analysis were included in the multivariable Cox regression time-to-event analysis for the primary outcome. Kaplan-Meier curves were constructed of the most significant variables on Cox regression as a visual aid. RESULTS: The following variables achieved significance on Cox regression for an association with development of ipsilateral hemispheric ischemic events after the index CEA hospital admission: lack of patch placement at CEA site (hazard ratio [HR], 18.24; P < .0001), lack of antiplatelet therapy at long-term follow-up (LTFU; HR, 9.75; P < .0001), lack of statin therapy at LTFU (HR, 3.18; P < .001), lack of statin therapy at hospital discharge (HR, 1.25; P = .015), anticoagulation at LTFU (HR, 1.53; P < .001), development of >70% recurrent stenosis (HR, 2.15; P < .001), and shunt use at surgery (HR, 1.20; P = .007). Patients with patch placement at surgery and patients with confirmed antiplatelet therapy at LTFU had had 99.8% and 99.6% freedom from an ischemic event ipsilateral to the side of the CEA at LTFU, respectively. This finding is in contrast to the 5.7% and 4.7% positivity for ischemic events for those without patch placement at surgery and those not receiving antiplatelet therapy at LTFU, respectively (P < .0001 for both). CONCLUSIONS: Performance of patch angioplasty arterial closure was remarkably protective against ipsilateral cerebral ischemic events at LTFU after CEA. Discharging and maintaining patients with antiplatelet and statin medication after CEA significantly reduces the incidence of future ipsilateral ischemic events. Thus, a significant opportunity exists for enhanced outcomes with improved implementation of these measures.
