<b><i>Background/Aim:</i></b> Current guidelines recommend transthoracic echocardiography (TTE) and ambulatory rhythm monitoring following ischemic stroke or transient ischemic attack (TIA) of undetermined cause for identifying cardioembolic sources (CES). Due to ongoing controversies about this routine strategy, we evaluated its yield in a real-world setting. <b><i>Methods:</i></b> In a tertiary medical center, we retrospectively evaluated consecutive patients with ischemic stroke or TIA of undetermined cause, who (after standard work-up) underwent TTE, ambulatory rhythm monitoring, or both. CES were classified as major if probably related to ischemic events and warranting a change of therapy. <b><i>Results:</i></b> Between January 2014 and December 2017, 674 patients had ischemic stroke or TIA of undetermined cause. Of all 484 patients (71.8%) who underwent TTE, 9 (1.9%) had a major CES. However, 7 of them had already been identified for cardiac evaluation due to new major electrocardiographic abnormalities or cardiac symptoms. Thus, only 2 patients (0.4%) truly benefitted from unselected TTE screening. Ambulatory rhythm monitoring was performed in 411 patients (61.0%) and revealed AF in 10 patients (2.4%). <b><i>Conclusion:</i></b> Detecting a major CES is essential because appropriate treatment lowers the risk of recurrent stroke. Nonetheless, in this real-world study that aimed at routine use of TTE and ambulatory rhythm monitoring in patients with ischemic stroke or TIA of undetermined cause, the prevalence of major CES was low. Most patients with major CES on TTE already had an indication for referral to a cardiologist, suggesting that major CES might also have been identified with a much more selective use of TTE.

Introduction: Prior stroke is a risk factor for stroke and bleeding during anticoagulation in patients with atrial fibrillation (AF). Although rivaroxaban is widely prescribed to reduce their risk of stroke in patients with nonvalvular AF (NVAF), the real-world evidence on rivaroxaban treatment is limited. We aimed to examine the outcomes of rivaroxaban treatment in NVAF patients with prior ischemic stroke/transient ischemic attack (TIA) by using the data of the Xarelto Post-Authorization Safety and Effectiveness Study in Japanese ­Patients with AF, a prospective, single-arm, observational study. Methods: The clinical outcomes of 9,578 patients who completed the 1-year follow-up were evaluated. Safety and effectiveness outcomes were compared between patients with and without prior ischemic stroke/TIA. Results: Among the patients, 2,153 (22.5%) had prior ischemic stroke/TIA. They were significantly older and had lower body weight, lower creatinine clearance, higher CHADS2, CHA2DS2-VASc, and modified HAS-BLED scores as compared to those without prior ischemic stroke/TIA. Any bleeding (9.1 vs. 7.2 events per 100 patient-years), major bleeding (2.3 vs. 1.6 events per 100 patient-years), and stroke/non-central nervous system systemic embolism/myocardial infarction (3.4 vs. 1.3 events per 100 patient-years) were more frequent in patients with prior ischemic stroke/TIA. Stepwise regression analysis suggested that body weight of ≤50 kg and diabetes mellitus were predictive of major bleeding in patients with prior ischemic stroke/TIA. Conclusions: Safety and effectiveness event rates were higher in patients with prior ischemic stroke/TIA than those without. This might be explained by differences in several risk profiles including age, body weight, renal function, and risk scores such as CHADS2 between the groups. Clinicaltrials.gov: NCT01582737.

Ischemic Attack

Ischemic stroke and transient ischemic attack (TIA) are the most common cerebrovascular disorder and leading cause of death in China. The Effective secondary prevention is the vital strategy for reducing stroke recurrence. The aim of this guideline is to provide the most updated evidence-based recommendation to clinical physicians from the prior version. Control of risk factors, intervention for vascular stenosis/occlusion, antithrombotic therapy for cardioembolism, and antiplatelet therapy for noncardioembolic stroke are all recommended, and the prevention of recurrent stroke in a variety of uncommon causes and subtype provided as well. We modified the level of evidence and recommendation according to part of results from domestic RCT in order to facility the clinical practice.

Background: We aimed to clarify associations between pre-admission risk scores (CHADS2, CHA2DS2-VASc, and HAS-BLED) and 2-year clinical outcomes in ischemic stroke or transient ischemic attack (TIA) patients with non-valvular atrial fibrillation (NVAF) using a prospective, multicenter, observational registry. Methods: From 18 Japanese stroke centers, ischemic stroke or TIA patients with NVAF hospitalized within 7 days after onset were enrolled. Outcome measures were defined as death/disability (modified Rankin Scale score ≥3) at 2 years, 2-year mortality, and ischemic or hemorrhagic events within 2 years. Results: A total of 1,192 patients with NVAF (527 women; mean age, 78 ± 10 years), including 1,141 ischemic stroke and 51 TIA, were analyzed. Rates of death/disability, mortality, and ischemic or hemorrhagic events increased significantly with increasing pre-admission CHADS2 (p for trend <0.001 for death/disability and mortality, p for trend = 0.024 for events), CHA2DS2-VASc (p for trend <0.001 for all), and HAS-BLED (p for trend = 0.004 for death/disability, p for trend <0.001 for mortality, p for trend = 0.024 for events) scores. Pre-admission CHADS2 (OR per 1 point, 1.52; 95% CI 1.35–1.71; p <0.001 for death/disability; hazard ratio (HR) per 1 point, 1.23; 95% CI 1.12–1.35; p <0.001 for mortality; HR per 1 point, 1.14; 95% CI 1.02–1.26; p = 0.016 for events), CHA2DS2-VASc (1.55, 1.41–1.72, p < 0.001; 1.21, 1.12–1.30, p < 0.001; 1.17, 1.07–1.27, p < 0.001; respectively), and HAS-BLED (1.33, 1.17–1.52, p < 0.001; 1.23, 1.10–1.38, p < 0.001; 1.18, 1.05–1.34, p = 0.008; respectively) scores were independently associated with all outcome measures. Conclusions: In ischemic stroke or TIA patients with NVAF, all pre-admission risk scores were independently associated with death/disability at 2 years and 2-year mortality, as well as ischemic or hemorrhagic events within 2 years.
