Prothrombotic State in Atrial Fibrillation Patients With One Additional Risk Factor of the CHA2DS2-VASc Score (Beyond Sex)
ConclusionsA prothrombotic state (increased thrombin generation, denser fibrin clots, impaired fibrinolysis, and endothelial injury) characterizes patients with AF with 1 additional clinical stroke risk factor (beyond sex), with age 65-74 years being particularly associated with prothrombotic indices.RésuméContexteLa question de savoir si un état prothrombotique survient chez les patients atteints de fibrillation auriculaire (FA) à faible risque d’accident vasculaire cérébral (AVC) n’a pas été élucidée.MéthodologieNous avons étudié 118 patients atteints de FA présentant un score CHA2DS2-VASc (insuffisance...

Stroke Prevention, Evaluation of Bleeding Risk, and Anticoagulant Treatment Management in Atrial Fibrillation Contemporary International Guidelines
Publication date: May 2019Source: Canadian Journal of Cardiology, Volume 35, Issue 5Author(s): Marco Proietti, Deirdre A. Lane, Giuseppe Boriani, Gregory Y.H. LipAbstractIn recent years the management of atrial fibrillation patients has progressively and substantially changed because of the introduction of new treatments and the availability of new data regarding the epidemiology and clinical management of these patients. In the past 2 years alone, there have been 7 new guidelines or guideline updates that have been published, which have introduced new recommendations and significantly revised previously published ones. Tw...

Atrial Transcriptional Profiles of Molecular Targets Mediating Electrophysiological Function in Aging and Pgc-1 β Deficient Murine Hearts
Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health pro...

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Characterizing the Penumbras of White Matter Hyperintensities and Their Associations With Cognitive Function in Patients With Subcortical Vascular Mild Cognitive Impairment
Conclusion In this study, reduced CBF and FA and increased MD in the inner NAWM layers for both PVWMH and DWMH suggested extensive WM alterations beyond the visible WM lesions commonly observed on clinical MRI of svMCI subjects. CBF penumbras cover more extensive WM at risk than DTI penumbras, suggesting the likelihood that compromised CBF precedes white matter integrity changes, and CBF penumbras may be a potential target for the prevention of further microstructural white matter damage. The imaging parameters investigated, however, did not correlate to cognition. Author Contributions YZ, QX, and XG conceived and desig...

Screening for Atrial Fibrillation using a Mobile, Single-Lead Electrocardiogram in Canadian Primary Care Clinics
ConclusionPreviously undiagnosed AF is common in older individuals attending primary care clinics. The Kardia Mobile ECG device appears to be an effective screening tool for AF with high physician acceptability. More research on the feasibility of such novel technologies is warranted for future consideration of integration in population-based screening programs.

Peridevice Leak After Left Atrial Appendage Closure: Incidence, Risk Factors, and Clinical Impact
ConclusionsThe PDL rate detected by CCTA after LAAC was high, especially in cases with a low device compression ratio (< 10%), but decreased over time. The incidence of MACE was quantitatively greater with PDL, but the difference was not statistically significant. Larger studies are needed to determine the clinical importance of PDL.RésuméIntroductionPeu d’études ont fait état des taux et des répercussions cliniques des fuites périprothétiques (FPP) après la fermeture de l’appendice auriculaire gauche (AAG) par voie percutanée.MéthodesNous avons inscrit de manière prospective tous les patients consécuti...

Comparison of Readmission and Death Among Patients With Cardiac Disease in Northern vs Southern Ontario
ConclusionsReadmissions were increased in those residing and hospitalized in the North. To reduce readmissions in the North, the quality of postacute transitional care should be examined further.RésuméContexteDes facteurs géographiques peuvent influer sur l’issue de maladies cardiovasculaires au Canada. Les maladies du système circulatoire constituent une raison majeure du taux de mortalité élevé dans le nord de l’Ontario, mais on ne sait pas si les patients hospitalisés pour une maladie cardiovasculaire connaissent des issues différentes par rapport aux personnes vivant dans le sud.MéthodologieNous avons exa...

Higher hospital readmission rates for cardiac patients in Northern vs. Southern Ontario: Importance
(Elsevier) Patients hospitalized with heart attacks, heart failure, atrial fibrillation or stroke in Northern Ontario, Canada, were more likely to be readmitted to the hospital and repeatedly hospitalized after discharge than those living in Southern Ontario. Yet, no geographical differences were found in 30-day survival. A new study recommends providing access to timely transitional care by clinicians who have the knowledge and expertise to treat patients recently discharged from hospital as one of several strategies necessary to reduce hospital readmission rates.

Direct Oral Anticoagulants in Cirrhotic Patients: Current Evidence and Clinical Observations.
Authors: Elhosseiny S, Al Moussawi H, Chalhoub JM, Lafferty J, Deeb L Abstract The introduction of Direct Oral Anticoagulants (DOACs) to the pharmaceutical market provided patients and clinicians with novel convenient and safe options of anticoagulation. The use of this class of medications is currently limited to venous thromboembolic therapy and prophylaxis, in addition to stroke prophylaxis in patients with nonvalvular atrial fibrillation. Despite their altered hemostasis, patients with cirrhosis are thought to be in a procoagulant state and thus prone to thrombus formation. Patients with cirrhosis might benefit...

Importance of risk reassessment in patients with atrial fibrillation in guidelines: Assessing risk as a dynamic process
Publication date: Available online 2 February 2019Source: Canadian Journal of CardiologyAuthor(s): Ting-Yung Chang, Gregory Y.H. Lip, Shih-Ann Chen, Tze-Fan ChaoAbstractThe appropriate use of oral anticoagulants (OACs) for stroke prevention in atrial fibrillation (AF) relies on the convenient and accurate stroke risk prediction scheme, namely the CHA2DS2-VASc score. Since AF patients would become older and accumulate more comorbidities, their risk (for example, as reflected by the CHA2DS2-VASc scores) are not static and could increase over time. The available data demonstrated that follow-up and delta CHA2DS2-VASc scores p...

Association Between Patient and Physician Sex and Physician-Estimated Stroke and Bleeding Risks in Atrial Fibrillation
ConclusionsOur study is the first to examine the association between patient and physician sex influences and stroke and bleeding risk estimation in AF. While there were differences in agreement between physician estimated stroke risk and calculated CHADS2 scores, these differences were small and unlikely to impact clinical practice; further, despite any perceived differences in the accuracy of risk assessment by sex, most patients received anticoagulation.
