Relationship between air pollution and stroke risk in patients with atrial fibrillation

Takeaway

  • There is a dose-dependent relationship between long-term air pollution and stroke events in patients with atrial fibrillation (AF).

Why this matters

    Several studies have established relationships between fine particulate matter ≤2.5 μm (PM2.5) and cardiovascular events, but studies in AF have focused on short-term pollution changes. Understanding long-term association of pollution with stroke risk may have important implications for public health and policy.
