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.

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.

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]

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.

Atrial fibrillation in young stroke patients: do we underestimate its prevalence?
ConclusionAF may be more common than expected in young patients with IS and is associated with increased NIHSS scores.

Left atrial volumes and associated stroke subtypes
This study is a standardized review of 633 patients admitted to the stroke service of a tertiary care hospital following a standardized stroke investigation and management pathway. Stroke subtypes were characterized using the Causative Classification System, using the hospitals online radiologic archival system with CCS certified stroke investigators. Patients with two mechanisms were excluded. Results: Patients with cardioembolic stroke had a higher proportion of atrial fibrillation (p

Is necessary to perform a transthoracic echocardiogram in all the patients with cryptogenic stroke during hospitalization?.
CONCLUSIONS. The application of our criteria in undetermined stroke patients help us to identify with high efficiency cardioembolic sources postponing the test to an ambulatory scenario in the rest of the patients. PMID: 23658033 [PubMed - in process]

Utility of Duranta, a wireless patch-type electrocardiographic monitoring system developed in Japan, in detecting covert atrial fibrillation in patients with cryptogenic stroke: A case report
Rationale: Subcutaneous implantable electrocardiographs are highly effective in detecting covert atrial fibrillation (AF) in cryptogenic stroke. However, these invasive devices are not indicated for all cryptogenic stroke patients, and noninvasive improvements over conventional Holter-type ambulatory electrocardiography are needed. We evaluated the clinical application and effectiveness of Duranta (ImageONE Co., Ltd.), a wireless patch-type electrocardiographic monitoring system developed in Japan for chronically ill patients or home-based patients at the end of life. A Duranta device was used to detect covert AF in patien...

Atrial premature activity detected after an ischaemic stroke unveils atrial myopathy.
CONCLUSIONS: After an ischaemic stroke or a transient ischaemic attack, excessive APCs are associated with LA remodelling. Thus, LA dilatation and dysfunction reflect early LA myopathy, which might itself be responsible for cardioembolic stroke. PMID: 32007362 [PubMed - as supplied by publisher]

Predicting Atrial Fibrillation after Ischemic Stroke: Clinical, Genetics, and Electrocardiogram Modelling
Conclusion: We demonstrated that a model combining clinical and electrocardiographic variables provided robust prediction of AF in our post-stroke population. Role of SNP in prediction of AF was limited.
