Rationale: Atrial fibrillation (AF) is associated with an increased risk of thromboembolism. This risk is currently assessed with scoring systems based on clinical characteristics. However, these tools have limited prognostic performance. Circulating biomarkers are proposed for improved prediction of major clinical events and individualization of treatments in patients with AF.
Objective: The aim was to assess the cost-effectiveness of precision medicine (PM), i.e., the use of combined biomarkers and clinical variables, in comparison to standard of care (SOC) for risk stratification in a hypothetical cohort of AF patients at risk of stroke.
Methods: A Markov cohort model was developed to evaluate the costs and quality-adjusted life-years (QALYs) of PM compared to SOC, over 20 years using a Canadian healthcare system perspective.
Results: PM decreased the mean per-patient overall costs by 7% ($94,932 vs $102,057 [Canadian dollars], respectively) and increased the QALYs by 12% (8.77 vs 7.68 QALYs, respectively). The calculated incremental cost-effectiveness ratio was negative, indicating that PM is an economically dominant strategy. These results were robust to one-way and probabilistic sensitivity analyses.
Conclusion: PM compared to SOC is economically dominant and is projected to generate cost savings.

Atrial FDG Uptake: Etiologies, Clinical Significance, and Implications.
Curr Cardiol Rep
January 2025
Department of Medical Imaging, Montreal Heart Institute, Montréal, Québec, Canada.
Purpose Of Review: This review aims to explore the clinical significance of atrial fluorodeoxyglucose (FDG) uptake observed in positron emission tomography (PET) scans, focusing on its association with atrial fibrillation (AF), cardiac sarcoidosis, and myocarditis. We discuss the implications of atrial uptake for patient management and prognosis.
Recent Findings: Recent studies have demonstrated that atrial FDG uptake is frequently present in patients with AF, particularly those with persistent AF, and is linked to increased risks of stroke and poorer outcomes after ablation.

Background: Heart failure (HF) is a heterogeneous clinical syndrome affecting a growing global population. Due to the high incidence of cardiovascular risk factors, a large proportion of the Western population is at risk for heart failure. Oxidative stress and inflammation play a crucial role in the pathophysiology of heart failure with preserved ejection fraction (HFpEF).

Neurocognitive disorders are a major public health challenge, affecting 55 million people, and are projected to triple by 2050. This year's research highlights pathological mechanisms such as mitochondrial dysfunction and brain inflammation. Modifiable risk factors, such as vision loss, underscore the importance of early prevention.
