Management of Acute Coronary Syndromes Beyond the First Year: A Canadian Clinical Practice Survey.

ABSTRACT: Background: Antithrombotic management following acute coronary syndromes (ACSs) has evolved significantly. However, given lingering uncertainty as to when an ACS may be considered stable, there is the possibility of practice divergence beyond the first year.

Methods: An online adaptive survey describing patients with varying cardiac and extracardiac ischemic risk was developed in order to asses self-reported physician practice intentions pertaining to the antithrombotic management of ACS patients who lack a formal indication for therapeutic anticoagulation. Provincial "champions" (Prince Edward Island not represented) were identified to ensure dissemination of the survey within their jurisdictions via 3 coordinated e-mailings; the survey was made available in French and English from November 2018 through January 2019.

Results: A total of 135 practitioners responded to the survey (response rate 15%). Surveys were fully completed in all cases. Nearly all respondents (97%) were cardiologists; 76% worked at an academic center, and 54% had been in practice ? 10 years. Most respondents (81%-90%, depending on the scenario) preferred ticagrelor-based dual antiplatelet therapy as the initial ACS treatment. However, beyond 12 months, management decisions differed significantly according to the balance of cardiac and extracardiac risk.

Conclusions: This study provides a first look at how the introduction of rivaroxaban 2.5 mg might be integrated into the clinical management of ACS patients beyond the first year in Canada. Whether to pursue dual antiplatelet therapy or transition early to low-dose rivaroxaban plus acetylsalicylic acid will likely be driven by patient clinical characteristics and perceived cardiac vs extra-cardiac ischemic risk.

Project description:Background Data in the literature on acute coronary syndrome in sub-Saharan Africa are scarce. Methods and Results We conducted a systematic review of the MEDLINE (PubMed) database of observational studies of acute coronary syndrome in sub-Saharan Africa from January 1, 2010 to June 30, 2020. Acute coronary syndrome was defined according to current definitions. Abstracts and then the full texts of the selected articles were independently screened by 2 blinded investigators. This systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. We identified 784 articles with our research strategy, and 27 were taken into account for the final analysis. Ten studies report a prevalence of acute coronary syndrome among patients admitted for cardiovascular disease ranging from 0.21% to 22.3%. Patients were younger, with a minimum age of 52 years in South Africa and Djibouti. There was a significant male predominance. Hypertension was the main risk factor (50%-55% of cases). Time to admission tended to be long, with the longest times in Tanzania (6.6 days) and Burkina Faso (4.3 days). Very few patients were admitted by medicalized transport, particularly in Côte d'Ivoire (only 34% including 8% by emergency medical service). The clinical presentation is dominated by ST-elevation sudden cardiac arrest. Percutaneous coronary intervention is not widely available but was performed in South Africa, Kenya, Côte d'Ivoire, Sudan, and Mauritania. Fibrinolysis was the most accessible means of revascularization, with streptokinase as the molecule of choice. Hospital mortality was highly variable between 1.2% and 24.5% depending on the study populations and the revascularization procedures performed. Mortality at follow-up varied from 7.8% to 43.3%. Some studies identified factors predictive of mortality. Conclusions The significant disparities in our results underscore the need for a multicenter registry for acute coronary syndrome in sub-Saharan Africa in order to develop consensus-based strategies, propose and evaluate tailored interventions, and identify prognostic factors.
