Ischemic Stroke Management: Posthospitalization and Transition of Care
Am Fam Physician. 2023 Jul;108(1):70-77.ABSTRACTIschemic stroke is a major cause of morbidity and mortality worldwide. Ischemic stroke and transient ischemic attack exist on a continuum of the same disease process. Ischemic stroke is common, and more than 85% of stroke risk is attributed to modifiable risk factors. The initial management of acute stroke is usually performed in the emergency department and hospital settings. Family physicians have a key role in follow-up, ensuring that a complete diagnostic evaluation has been performed, addressing modifiable risk factors, facilitating rehabilitation, and managing chronic s...

Stroke and bleeding risk assessment in atrial fibrillation: when, how, and why?
The objective of this review article is to provide an overview of stroke and bleeding risk assessment in AF. There would be particular emphasis on when, how, and why to use these risk stratification schemes, with a specific focus on the CHADS2 [congestive heart failure, hypertension, age, diabetes, stroke (doubled)], CHA2DS2-VASc [congestive heart failure or left ventricular dysfunction, hypertension, age ≥75 (doubled), diabetes, stroke (doubled)-vascular disease, age 65–74 and sex category (female)], and HAS-BLED [hypertension (i.e. uncontrolled blood pressure), abnormal renal/liver function, stroke, bleeding his...

Stroke risk and suboptimal thromboprophylaxis in Chinese patients with atrial fibrillation: Would the novel oral anticoagulants have an impact?
Abstract: Background: The risk of stroke associated with atrial fibrillation (AF) is higher in Far Eastern population than in Western population, and warfarin use suboptimal. There is uncertainty whether the novel oral anticoagulants (NOACs) would have a major impact on stroke prevention in Far Eastern populations with AF.Objectives: We investigated current antithrombotic therapy use on stroke and bleeding risk, determinants of warfarin use and performed a modeling analysis of the net clinical benefit of the NOACs (apixaban, dabigatran) in a large cohort of Chinese patients with AF.Methods: We studied 1034 Chinese patients...

Evidence for the Prevention and Treatment of Stroke in Dialysis Patients.
Abstract The risks of both ischemic and hemorrhagic stroke are particularly high in dialysis patients of any age and outcomes are poor. It is therefore important to identify strategies that safely minimize stroke risk in this population. Observational studies have been unable to clarify the relative importance of traditional stroke risk factors such as blood pressure and cholesterol in those on dialysis, and are affected by biases that usually make them an inappropriate source of data on which to base therapeutic decisions. Well-conducted randomized trials are not susceptible to such biases and can reliably invest...

Oral Anticoagulants vs. Aspirin for Stroke Prevention in Patients with Non-Valvular Atrial Fibrillation: The Verdict is in
This article summarizes a recently published individual patient meta-analysis of all published RCTs comparing OAC and ASA in AF. In total, 4052 patients randomized to OAC or ASA were similar regarding important prognostic factors. Patients receiving OAC had a significantly lower risk of any stroke (hazard ratio [HR] 0.54 [95% CI 0.43–0.71]), ischemic stroke (HR 0.48 [0.37–0.63]), or cardiovascular events (HR 0.71 [0.59–0.85]). Patients receiving OAC were more likely to experience major bleeding (HR 1.71 [1.21–2.41]). The benefit of OAC was most prominent in patients at a high risk of stroke and other cardiovascular...

Left atrial appendage occlusion for prevention of stroke in nonvalvular atrial fibrillation: a meta-analysis
Conclusion Our data suggest that LAAO is a reasonable option for stroke prophylaxis in AF when anticoagulation is not an option, and the risk for stroke outweighs the risk of procedural complications. Data were limited with the use of most available devices. To better establish the risk and benefit of LAAO in comparison with standard therapy, more randomized controlled trials are necessary.

When a Single Antiplatelet Agent for Stroke Prevention Is Not Enough: Current Evidence and Future Applications of Dual Antiplatelet Therapy.
Abstract OPINION STATEMENT: For secondary stroke prevention, long-term dual antiplatelet therapy is not recommended due to increased bleeding risks. There is no specific evidence for using dual antiplatelet therapy for cervical artery dissection or for adding a second antiplatelet agent after a stroke while taking aspirin monotherapy. For patients with atrial fibrillation and stroke/TIA unable to tolerate warfarin, aspirin monotherapy is reasonable. Dual antiplatelet therapy carries a similar risk of major bleeding as warfarin that offsets reductions in stroke risk. Dual antiplatelet therapy is recommended for end...

GSE66724 Hsp70 protects from stroke in atrial fibrillation patients by preventing thrombosis with no increased bleeding risk
Contributors : Mikel Allende ; José HermidaSeries Type : Expression profiling by arrayOrganism : Homo sapiensAtrial fibrillation (AF) is a major risk factor for cardioembolic stroke. Anticoagulant drugs are effective in preventing AF-related stroke. However, the high frequency of anticoagulant-associated major bleeding is a major concern particularly when antiplatelet treatment is simultaneously administered. Here, microarray analysis in peripheral blood cells in eight patients with AF and stroke and eight AF subjects without stroke identified a stroke related gene expression pattern. HSPA1B, which encodes for heat-shock ...

Factors Influencing Oral Anticoagulant Prescribing Practices for Atrial Fibrillation among Cardiologists, Internists, and Vascular Neurologists (P1.227)
Conclusions: Medical specialties differ in their reasons for selecting NOACs over warfarin and in their use of aspirin with warfarin. Educational interventions may prevent misinterpretations of clinical trial results, particularly with regards to comparative efficacy in the prevention of ischemic stroke and intracerebral hemorrhage. Disclosure: Dr. Leung has nothing to disclose. Dr. Mcallister has nothing to disclose. Dr. Selim has nothing to disclose. Dr. Fisher has nothing to disclose.

Hsp70 protects from stroke in atrial fibrillation patients by preventing thrombosis without increased bleeding risk
Conclusions Hsp70 induction is a novel approach to delay thrombus formation with minimal bleeding risk, and is especially promising for treating AF patients and in other situations where there is also a major bleeding hazard.
