Importance of Considering Competing Risks in Time-to-Event Analyses: Application to Stroke Risk in a Retrospective Cohort Study of Elderly Patients With Atrial Fibrillation Original Articles
Conclusions: The incidence of death without stroke was 9-fold higher than that of stroke, leading to biased estimates of stroke risk with traditional time-to-event methods. Statistical methods that appropriately account for competing risks should be used to mitigate this bias.

Secondary prevention treatment after acute stroke in older South Asian, Chinese and other Canadians: a retrospective data analysis.
Abstract BACKGROUND: Little is known about whether there are differences in medication use between older patients of Chinese descent, those of South Asian descent and other Canadian patients after acute ischemic or primary intracerebral hemorrhagic stroke. The aim of this population-based study was to evaluate potential ethnic differences in secondary prevention pharmacotherapy after acute stroke. METHODS: Using health administrative data, we conducted a retrospective analysis of all patients aged 66 years or more admitted to hospital with acute stroke in Ontario (1997-2011) and British Columbia (1997-2009). ...

Elevated Incidence of Atrial Fibrillation and Stroke in Patients with Atrial Flutter – A Population-Based Study
Conclusions Patients with isolated atrial flutter develop atrial fibrillation and stroke at a higher rate than the general population. Catheter ablation reduces but does not eliminate future AF incidence and stroke risk and continued anticoagulation after successful atrial flutter ablation may therefore be warranted. Teaser We examine the incidence of atrial fibrillation and stroke in a large real-world cohort of patients with atrial flutter, and the impact of atrial flutter ablation. Patients with atrial flutter developed atrial fibrillation and stroke at a higher rate than the general population. Atrial flutter ablation ...

The multiple causes of stroke in atrial fibrillation: Thinking broadly
Publication date: Available online 30 August 2018Source: Canadian Journal of CardiologyAuthor(s): Atlantic D’Souza, Kenneth S. Butcher, Brian H. BuckAbstract:Atrial Fibrillation (AF) is numerically the most important risk factor for stroke. It is well established that patients with AF have a five-fold increased risk of stroke relative to those without, and that anticoagulation reduces the risk of stroke by approximately two-thirds. Definitively attributing the mechanism of an individual stroke to AF is much more problematic, however. In fact, there is no way to reliably establish the etiology of any ischemic infarction. ...

XANTUS-EL: A real-world, prospective, observational study of patients treated with rivaroxaban for stroke prevention in atrial fibrillation in Eastern Europe, Middle East, Africa and Latin America
ConclusionsXANTUS-EL confirmed low stroke and major bleeding rates in patients with NVAF from EEMEA and Latin America. The population was younger but with more heart failure and hypertension than XANTUS; stroke/SE rate was similar but major bleeding lower.

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.

Family Physician Prescribing Practices and Perspectives on Shared Decision-Making Regarding the Use of Oral Anticoagulants for Stroke Prevention in Patients 75  Years or Older With Atrial Fibrillation
CONCLUSION: Family physicians strongly consider patient risks and utilize risk-assessment tools when initiating OAC in older adults with AF. Despite all physicians reporting the use of shared decision-making and that their patients were educated on the indications for OAC, confidence in initiating treatment was variable. Further exploration into factors impacting physician confidence is needed.PMID:36960556 | DOI:10.1177/21501319231164060

Oral anticoagulation for stroke prevention in Canadian practice: Stroke Prevention and Rhythm Interventions in Atrial Fibrillation (SPRINT-AF) registry
Conclusions In this contemporary Canadian AF registry, the rate of guideline-concordant OAC use was high. About half of OAC-treated patients received NOAC agents. Patient- and physician-driven preferences such as side effect profile, perceived greater efficacy, and cost were strong determinants of NOAC over warfarin use. Teaser This is a cross-sectional, retrospective analysis of 936 patients with non-valvular atrial fibrillation enrolled from 106 practices in Canada between December 2012 and July 2013. We observed that the rate of guideline-concordant oral anticoagulation use was high (90%), with new direct oral anticoagu...

Stroke Prevention for High-Risk Atrial Fibrillation in the Emergency Setting: The Emergency Physician Perspective
Publication date: February 2018 Source:Canadian Journal of Cardiology, Volume 34, Issue 2 Author(s): Clare L. Atzema Atrial fibrillation is a frequent reason for presentation to an emergency department (ED), and the number of these visits are increasing. This creates an opportunity to improve the suboptimal rate of oral anticoagulation (OAC) use in patients with atrial fibrillation who are at high risk of stroke. However, there are very few data on whether OAC initiation in the ED, compared with referral to the longitudinal health care provider to initiate it, results in better long-term use. Moreover, for ethical and med...

Barriers to using stroke-preventing anticoagulants in Canada hinder appropriate management of patients with atrial fibrillation
(Elsevier) International guidelines recommend direct oral anticoagulants (DOACs) over warfarin to prevent stroke for most patients with atrial fibrillation (AF). However, a substantial portion of patients in Canada, who would benefit from anticoagulation, do not receive it adequately or at all. Experts review the evidence for the use of DOACs in the Canadian Journal of Cardiology, discuss reasons for the large gap between guidelines and clinical practice, including policy and funding barriers, and propose strategies for the future.
