Background Circulating very-long-chain saturated fatty acids ( VLSFAs ) are integrated biomarkers of diet and metabolism that may point to new risk pathways and potential targets for heart failure ( HF ) prevention. The associations of VLSFA to HF in humans are not known. Methods and Results Using a
Ceramides exhibit multiple biological activities that may influence the pathophysiology of heart failure. These activities may be influenced by the saturated fatty acid carried by the ceramide (Cer). However, the associations of different circulating Cer species, and their
