Platelet Count Predicts Adverse Clinical Outcomes After Ischemic Stroke or TIA: Subgroup Analysis of CNSR II
Conclusion: In ischemic stroke or TIA patients with platelet count within normal range, platelet count may be a qualified predictor for long-term recurrent stroke, mortality, and poor functional outcome. Introduction Platelets exert a critical role in the pathogenesis of atherosclerotic complications of cardio-cerebrovascular disease, contributing to thrombus formation, and embolism (1, 2). Previous literature reported that platelets of various size and density are produced by megakaryocytes of different size and stages of maturation in different clinical conditions, suggesting various platelet patterns in differen...

Treatment with Clopidogrel Prior to Acute Non-Cardioembolic Ischemic Stroke Attenuates Stroke Severity
Background: Clopidogrel reduces the risk of non-cardioembolic ischemic stroke, but it is unclear whether it affects the severity and outcome of stroke. We aimed at evaluating the effect of prior treatment with clopidogrel on acute non-cardioembolic ischemic stroke severity and in-hospital outcome. Methods: We prospectively studied 608 consecutive patients (39.5% males, age 79.1 ± 6.6 years) who were admitted with acute ischemic stroke. The severity of stroke was assessed at admission with the National Institutes of Health Stroke Scale (NIHSS). Severe stroke was defined as NIHSS ≥21. The outcome was assessed using the de...

Cryptogenic Stroke: Diagnostic Workup and Management
AbstractPurpose of reviewCryptogenic stroke describes a subset of ischemic stroke for which no cause can be found despite a structured investigation. There are a number of putative mechanisms of cryptogenic ischemic stroke including a covert structural cardiac lesion, paroxysmal atrial fibrillation, hypercoagulable state or undiagnosed malignancy. Because many of these proposed mechanisms are embolic – and based on studies of thrombus history showing commonalities between thrombus composition between cardioembolic and cryptogenic strokes – the concept of embolic stroke of undetermined source (ESUS) (Hart et al. Lancet ...

Abstract 10: Pre-stroke Antithrombotic Therapy and Stroke Severity in Acute Ischemic Stroke Patients with Atrial Fibrillation Session Title: Abstract Oral Session: Outcomes
Conclusions: A majority of AF patients presenting with AIS are not on guideline recommended anticoagulation or are not therapeutic on their anticoagulation. Even when strokes occurred on therapeutic warfarin or a NOAC, the strokes were less severe. These findings highlight the huge opportunities to further improve proper use of oral anticoagulants in eligible AF patients.

Secondary Stroke Prevention in Cryptogenic Stroke and Embolic Stroke of Undetermined Source (ESUS)
AbstractPurpose of the ReviewThe purpose of the study was to review the literature on cryptogenic stroke and embolic stroke of undetermined stroke (ESUS). Cryptogenic stroke according to TOAST criteria is a stroke which is not due to cardiogenic embolism, small vessel disease with lacunes or large vessel disease of brain supplying arteries. In the context of secondary stroke prevention studies, cryptogenic stroke is not operationally defined.Recent FindingsThe new concept of “embolic stroke of undetermined source” (ESUS) provides an operational definition. ESUS is diagnosed as a non-lacunar stroke on cerebral imaging a...

Women With Osteoarthritis Are at Increased Risk of Ischemic Stroke: A Population-Based Cohort Study.
CONCLUSION: Women with OA are at an elevated risk of ischemic stroke. A close monitoring of hypertension, atrial fibrillation, and other stroke related comorbidities is required for stroke prevention for OA patients. PMID: 33536376 [PubMed - as supplied by publisher]

Abstract 263: The Risk of Stroke or Systemic Embolism for Antithrombotic Treatment Episodes among Non-Valvular Atrial Fibrillation (NVAF) Patients Session Title: Poster Session II
Conclusion: Warfarin TTR ≥55% was associated with the greatest reduction in stroke/SE among the antithrombotic treatment groups examine here. Future studies should examine modifiable factors to improve outcomes for patients with warfarin TTR <55% or those who are off antithrombotic therapy.

Cilostazol may prevent cardioembolic stroke in patients undergoing antiplatelet therapy.
CONCLUSIONS: Cilostazol may prevent cardioembolic stroke in patients undergoing antiplatelet therapy. This could be a novel strategy for cardioembolic stroke prevention potentially by affecting cardiac remodelling, in contrast to secondary anticoagulant therapy.

Decision-Making in Clinical Practice: Oral Anticoagulant Therapy in Patients with Non-valvular Atrial Fibrillation and a Single Additional Stroke Risk Factor
AbstractApproximately 1 in 3 –4 patients presenting with an ischemic stroke will also have atrial fibrillation (AF), and AF-related strokes can be effectively prevented using oral anticoagulant therapy (OAC), either with well-controlled vitamin K antagonists (VKAs) or non-vitamin K antagonist oral anticoagulants (NOACs). In a ddition, OAC use (both VKAs and NOACs) is associated with a 26% reduction in all-cause mortality (VKAs) or an additional 10% mortality reduction with NOACs relative to VKAs. The decision to use OAC in individual AF patient is based on the estimated balance of the benefit from ischemic stroke reducti...

Opportunities for intervention: stroke treatments, disability and mortality in urban Tanzania
ConclusionsThe 90-day mortality of stroke presenting at MNH is 50%, much higher than in higher income settings. Although severe stroke presentations are a major factor, efforts to improve the quality of care and prevent complications of stroke are urgently needed. Acute stroke interventions with low number needed to treat represent challenging long-term goals.

New Watchman study reports positive data
New data from a study of Boston Scientific (NYSE:BSX)’s Watchman left atrial appendage closure device reports positive results in a study comparing it to warfarin, an anticoagulant drug treatment, in patients with nonvalvular atrial fibrillation. The 2,406-patient study, published in the Journal of the American College of Cardiology, reported a lower rate of hemorrhagic strokes, unexplained and cardiovascular death and non-procedural bleeding when compared to warfarin. “I think the fact that we now actually have some good scientific data in the field is terribly important, it has been lacking. But I think we...

Development of a novel composite stroke and bleeding risk score in patients with atrial fibrillation: The AMADEUS study.
CONCLUSION We have developed and validated 2 novel composite scores for stroke/thromboembolism/ bleeding that offer good discriminatory and predictive performance. However, these composite risk scores did not perform better than the easier and more practical 'traditional' stroke and bleeding risk scores that are currently in use, which allow greater practically and more personalised balancing of risks.

Check the pulse to track irregular heartbeats after a stroke
The rapid, irregular heartbeat known as atrial fibrillation is a key cause of stroke. New research suggests that it's to blame for more strokes than doctors realized, and that simply measuring the pulse could help detect unrecognized atrial fibrillation and avert a second stroke, reports the October 2014 Harvard Heart Letter. Atrial fibrillation can come and go, lasting from a few seconds to several days. Some people have distressing symptoms such as palpitations, dizziness, or chest pressure. For many others, atrial fibrillation passes silently. Either way, blood can pool in the heart's upper chambers, or atria. This stag...
