Lipids & metabolic liver disease
Associations between use of aspirin and magnetic resonance imaging‐derived liver fat and fibroinflammation
Authors' conclusion
In this large population-based cohort, aspirin use was linked to reduced liver fat, but a small, clinically insignificant (i.e., <80 ms) increase in cT1. These findings suggest aspirin may mitigate steatosis through metabolic pathways but does not necessarily rapidly reverse fibroinflammatory injury.
