Metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with a 19% increased risk of incident atrial fibrillation (AF), with risk escalating as liver disease severity (fibrosis/MASH) increases.

If you have MASLD, you have a significantly higher risk of developing atrial fibrillation, even in early stages. Managing metabolic risk factors (weight, blood sugar, blood pressure) is not just about liver health but is a critical strategy for preventing heart rhythm disorders. Early detection and comprehensive management of MASLD are crucial to mitigate this dual burden.

GoodSupportsHIGH confidence
Research highlights a significant link, showing that people with MASLD face a 19% higher likelihood of developing AF compared to those without the condition, with this risk increasing in individuals with more advanced liver disease

Why this rating

Based on multiple retrospective cohorts and meta-analyses cited (e.g., Simon et al., Mantovani et al.), though causality is complex due to shared risk factors.
