Clinical Differences Between Stroke and Stroke Mimics in Code Stroke Patients
CONCLUSION: Some clinical and neurological characteristics have been identified to help differentiate stroke mimics from true stroke. In particular, the likelihood of stroke tended to increase as the number of accompanying focal neurological deficits increased.PMID:35191231 | DOI:10.3346/jkms.2022.37.e54

Cardiovascular diseases in patients 65 years and younger with non-cardiogenic stroke.
CONCLUSIONS: Aetiologically heterogeneous stroke and cardiogenic stroke are the most commonly observed among young stroke patients. Cardiomyopathy and atrial fibrillation are the most common sources of cerebral embolism in young patients with cardiogenic stroke. Nearly 1/5 of patients with a non-cardiogenic stroke have congenital or acquired structural changes in the heart. PMID: 27279848 [PubMed]

Diagnosis of atrial fibrillation after stroke and transient ischaemic attack: a systematic review and meta-analysis
Publication date: Available online 4 March 2015 Source:The Lancet Neurology Author(s): Luciano A Sposato , Lauren E Cipriano , Gustavo Saposnik , Estefanía Ruíz Vargas , Patricia M Riccio , Vladimir Hachinski Background Among patients with atrial fibrillation, the risk of stroke is highest for those with a history of stroke; however, oral anticoagulants can lower the risk of recurrent stroke by two-thirds. No consensus has been reached about how atrial fibrillation should be investigated in patients with stroke, and its prevalence after a stroke remains uncertain. We did a systematic review and meta-analysis to estimat...

Left Atrial Function Is Impaired in Some Patients With Stroke of Undetermined Etiology: Potential Implications for Evaluation and Therapy
Conclusions Patients with stroke of undetermined etiology with left atrial function (ejection fraction and strain) similar to that of cardioembolic stroke patients may be misclassified and could potentially benefit from prolonged electrocardiography monitoring. Left atrial function analysis (ejection fraction and strain) might help to identify potential cardioembolic sources in patients with stroke of undetermined etiology.

Electrocardiographic left atrial abnormalities and risk of incident stroke in hypertensive patients with electrocardiographic left ventricular hypertrophy
Conclusion: Abnormal PTFV1, a marker of left atrial abnormality, was strongly associated with incident stroke in hypertensive patients, independent of in-treatment SBP and other predictors of incident stroke. This association, in the absence of detectable atrial fibrillation, suggests that an underlying atrial cardiopathy may cause left atrial thrombus formation and a subsequent stroke without intervening clinically recognized atrial fibrillation.

Prevalence and Prognostic Features of ECG Abnormalities in Acute Stroke
Conclusions About 4 in 5 acute stroke patients in this African cohort had evidence of a baseline ECG abnormality, but presence of any atrial enlargement was the only independent ECG predictor of death or disability.

Premature atrial complexes in an ischemic stroke population and risk of recurrent stroke: a systematic review.
Authors: Sejr MH, Riahi S, Larsen TB, Nielsen JC, Nielsen PB Abstract INTRODUCTION: Premature atrial complexes (PACs) have been proposed as a possible mediator between normal sinus rhythm and atrial fibrillation (AF). The aim of this study was to summarize the available knowledge of association between PACs and recurrent stroke or transient ischemic attack (TIA) in ischemic stroke patients. Areas covered: In this systematic review, we investigated the risk of recurrent events in patients who experienced ischemic stroke or TIA. Occurrence of PACs in electrocardiographic monitoring after index stroke/TIA was required...

The CHA2DS2-VASc score and the risk of ischemic stroke in community-dwelling individuals with and without atrial fibrillation: The Atherosclerosis Risk In Communities (ARIC) study
Conclusion The risk of ischemic stroke is low across CHA2DS2-VASc score categories in community-dwelling individuals without AF. Individuals with AF are at high risk for ischemic stroke even with low CHA2DS2-VASc score, suggesting the need for stroke prevention in individuals with AF and one CHA2DS2-VASc stroke risk factor.

Cardiac Risk Factors for Stroke: A Comprehensive Mendelian Randomization Study
CONCLUSIONS: Available genetic data do not support substantial effects of cardiac traits on the risk of stroke beyond known clinical risk factors. Our findings highlight the need to carefully control for confounding and other potential biases in studies examining candidate cardiac risk factors for stroke.PMID:34911345 | DOI:10.1161/STROKEAHA.121.036306

Electrocardiographic left atrial abnormality and stroke subtype in the atherosclerosis risk in communities study
ObjectiveThe aim of this study was to assess the relationship between abnormally increased P‐wave terminal force in lead V1, an electrocardiographic (ECG) marker of left atrial abnormality, and incident ischemic stroke subtypes. We hypothesized that associations would be stronger with nonlacunar stroke, given that we expected left atrial abnormality to reflect the risk of thromboembolism rather than in situ cerebral small‐vessel occlusion. MethodsOur cohort comprised 14,542 participants 45 to 64 years of age prospectively enrolled in the Atherosclerosis Risk in Communities study and free of clinically apparent atrial f...

Prevalence of Patent Foramen Ovale in Ischaemic Stroke in Italy: Results of SISIFO Study
Conclusion: If any relationship exists between stroke and PFO, this is more likely in PACI and POCI at a younger age. Our results are consistent with recent findings that underline PFO alone must not be considered a significant independent predictor for stroke; so the presence of PFO alone doesn't permit rushed causal correlations or ‘therapeutic aggressiveness'.Cerebrovasc Dis 2015;39:162-169

Sensitive Detection of Atrial Fibrillation in Acute Stroke Patients by Short-Term Bedside Electrocardiography Monitoring Software Analysis
Conclusion: SRA was found to be highly sensitive to detect possible or definitive AF in clinical routine within a short monitoring time. However, low specificity and poor accuracy do not allow diagnosing AF by SRA alone, but with the high NPV compared to current diagnostic standard, it is a valid diagnostic tool to rule out AF. Thereby, SRA is a contribution to clarify stroke etiology.Cerebrovasc Dis 2018;45:54 –60

Clinical features of ischemic stroke in patients with nonvalvular atrial fibrillation combined with intracranial atherosclerotic stenosis
ConclusionNVAF with ICAS ischemic stroke is more likely to occur in older patients. Infarctions occurred mainly in the right cerebral hemisphere. Neurological deficits in NVAF are more severe than those in NVAF combined with ICAS and in simple ICAS ischemic strokes. HsCRP, LEVF, andNTpro-BNP seem to be closely associated with NVAF+ICAS ischemic stroke.
