Global Survey of the Frequency of Atrial Fibrillation-Associated Stroke: Embolic Stroke of Undetermined Source Global Registry Clinical Sciences
Conclusions— This cross-sectional global sample of patients with recent ischemic stroke shows a substantial frequency of AF-associated stroke throughout the world in proportion to the mean age of the stroke population. Most AF is identified by history or electrocardiography; the yield of conventional short-duration cardiac rhythm monitoring is relatively low. Patients with AF-associated stroke were typically elderly (>75 years old) and more often women.

Electrocardiographic Left Atrial Abnormality and Risk of Stroke: Northern Manhattan Study Clinical Sciences
Conclusions— ECG-defined left atrial abnormality was associated with incident cryptogenic or cardioembolic stroke independently of the presence of AF, suggesting atrial thromboembolism may occur without recognized AF.

Abnormal P-Wave Axis and Ischemic Stroke Clinical Sciences
Conclusions—aPWA is independently associated with ischemic stroke. This association seems to be stronger for cardioembolic strokes. Collectively, our findings suggest that alterations in atrial electric activation may predispose to cardiac thromboembolism independent of atrial fibrillation.

Carotid Atherosclerosis and Stroke in Atrial Fibrillation: The Atherosclerosis Risk in Communities Study Brief Reports
Conclusions— Increased cIMT and presence of carotid plaque are associated with increased risk of ischemic stroke in individuals with AF. Furthermore, they may improve risk prediction of stroke, over and above the CHA2DS2-VASc score.

Improved Detection of Silent Atrial Fibrillation Using 72-Hour Holter ECG in Patients With Ischemic Stroke: A Prospective Multicenter Cohort Study Clinical Sciences
Conclusions— In unselected survivors of stroke or TIA, 72-hour ECG monitoring is feasible and improves the detection rate of silent paroxysmal AF.

Premature Ventricular Complexes on Screening Electrocardiogram and Risk of Ischemic Stroke Brief Reports
Conclusions— PVCs are common on routine screening ECGs and are associated with an increased risk of ischemic stroke.

Systolic Blood Pressure Control and Mortality After Stroke in Hypertensive Patients Clinical Sciences
Conclusions— Lower achieved SBP (<144 mm Hg) is associated with a significantly increased risk of cardiovascular and all-cause mortality after initial stroke in hypertensive patients during short-term follow-up. Further study is required to determine ideal SBP goals after stroke. Clinical Trial Registration— URL: http://clinicaltrials.gov/. Unique identifier: NCT00338260.

Atrial Cardiopathy and the Risk of Ischemic Stroke in the CHS (Cardiovascular Health Study) Clinical Sciences
Conclusions—In addition to clinically apparent AF, other evidence of abnormal atrial substrate is associated with subsequent ischemic stroke. This finding is consistent with the hypothesis that thromboembolism from the left atrium may occur in the setting of several different manifestations of atrial disease.

Elevated Cardiac Troponin in Acute Stroke without Acute Coronary Syndrome Predicts Long-Term Adverse Cardiovascular Outcomes.
Conclusions. Elevated cardiac troponin in patients with acute stroke and no evidence of ACS is strong predictor of long-term cardiac outcomes. PMID: 25530906 [PubMed]

P-Wave Indices and Risk of Ischemic Stroke Clinical Sciences
Background and Purpose—Atrial cardiomyopathy is associated with an increased risk of ischemic stroke. P-wave terminal force in lead V1, P-wave duration, and maximum P-wave area are electrocardiographic parameters that have been used to assess left atrial abnormalities related to developing atrial fibrillation. The aim of this systematic review and meta-analysis was to examine their values for predicting ischemic stroke risk.Methods—PubMed and EMBASE databases were searched until December 2016 for studies that evaluated the association between P-wave indices and stroke risk. Both fixed- and random-effects models were us...

Effect of Middle Cerebral Artery Territory Ischemic Stroke on QT Interval
In this study, we investigated whether QT interval dynamics is different in patients with right and left middle cerebral artery (MCA) territory stroke.Method: Electrocardiogram (ECG) intervals were compared between baseline (retrieved retrospectively from medical records) and admission (acquired at the acute hospital admission) in 33 patients (65 ± 9.5 years) with right or left MCA territory ischemic stroke. Head computed tomography (CT), cardiac ultrasound, and cardiac CT scans were undertaken.Results: Stroke was located in the right MCA territory in 21 (64%) and in the left MCA territory in 12 (36%) patients. Patients w...

Heart rate and ischemic stroke: the REasons for Geographic And Racial Differences in Stroke (REGARDS) study
ConclusionIn REGARDS, high resting heart rates were associated with an increased risk of ischemic stroke compared with low heart rates. Further research is needed to examine whether interventions aimed to reduce heart rate decrease stroke risk.

Hospital Prenotification of Stroke Patients by Emergency Medical Services Improves Stroke Time Targets
Background: Prenotification to hospitals by emergency medical services of patients with suspected stroke is recommended to reduce delays in time-dependent therapies. We hypothesized that hospital prenotification would reduce recommended stroke time targets.Methods: We used the Robert Wood Johnson University Hospital (RWJUH) Brain Attack Database, which includes demographic and clinical data on all emergency department (ED) patients alerted as a Brain Attack between January 1, 2009 and June 30, 2010. Outcome variables included the time from door to stroke team arrival, computed tomographic (CT) scan completion, CT scan inte...

Electrocardiographic Assessment of Coronary Artery Disease and Stroke Risk Factors in Rural and Urban Tanzania: A Case–control Study
Conclusions: This is the first published study of ECG assessment of CAD and other stroke risk factors in an incident population of stroke cases in sub-Saharan Africa. It suggests that concomitant CAD in black African stroke cases is more common than previously suggested.

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.
