We hypothesize that metabolites implicated in this pathway may be associated with the risk of heart failure (HF) or atrial fibrillation (AF) in a population at high risk of cardiovascular disease.Objectives: We aimed to prospectively analyze the associations of kynurenine-related metabolites with the risk of HF and AF and to analyze a potential effect modification by the randomized interventions of the PREDIMED (Prevencion con Dieta MediterrAnea) trial with Mediterranean diet (MedDiet).Methods: Two case-control studies nested within the PREDIMED trial were designed.
