Cardiac Vulnerability to Cerebrogenic Stress as a Possible Cause of Troponin Elevation in Stroke Stroke
ConclusionsCertain cardiac and neurological conditions in acute ischemic stroke may contribute to troponin elevation. The proposed concept of cardiac vulnerability to cerebrogenic stress can be a practical interpretation of troponin elevation and electrocardiography abnormalities in stroke patients.

Electrocardiographic Monitoring for Detecting Atrial Fibrillation After Ischemic Stroke or Transient Ischemic Attack: Systematic Review and Meta-Analysis Original Articles
Conclusions— Longer duration of electrocardiographic monitoring after cryptogenic stroke is associated with a greater detection of AF. Future investigation is needed to determine the optimal duration of long-term monitoring.

Abstract 10: Contraindications to Oral Anticoagulation in the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF) Concurrent I Session B: Oral Abstract Presentations on Stroke Topics
Conclusions. Contraindications to OAC therapy among AF patients are common and often due to high bleeding risk. Furthermore, many patients with reported contraindications are taking warfarin, suggesting that many contraindications to warfarin therapy are minor, relative, or temporary.

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

Interrelationship between electrocardiographic left ventricular hypertrophy, QT prolongation, and ischaemic stroke: the REasons for Geographic and Racial Differences in Stroke Study
Conclusion The combination of ECG-LVH and prolonged QT is associated with a higher risk of ischaemic stroke compared with either condition in isolation, and the stroke risk for each condition does not depend on the presence of the other.

Stroke in cardiac sarcoidosis: Need to worry?
CONCLUSIONS: Ischemic stroke in patients with CS can be attributed to a cardioembolic phenomenon. A high index of clinical suspicion is needed for early diagnosis and management of these patients. PMID: 33189209 [PubMed - in process]

Detection of paroxysmal atrial fibrillation by prolonged electrocardiographic recording after ischaemic stroke in patients aged
CONCLUSION: This prospective observational study showed a low rate of paroxysmal AF among young patients presenting with stroke, on the basis of 21-day cardiac monitoring. This result highlights the need to identify patients who would benefit from such long monitoring. PMID: 25669959 [PubMed - as supplied by publisher]

How is Ambulatory Electrocardiogram Predictive of Stroke in Atrial Fibrillation Patients?
CONCLUSIONS: In Holter ECG monitoring detected AF, AF burden does not significantly impact the subsequent risk of stroke; whereas, CHA2DS2-VASc scoring is still a robust predictor of stroke risk. This may illustrate that once AF is detected from Holter ECG monitoring, underlying risk factors appear to be more predictive of subsequent stroke risk than atrial fibrillation burden.PMID:36262211 | PMC:PMC9576441 | DOI:10.1155/2022/7619669
