In a study with Italian HF patients, associated increased plasma ratios of Cer(C16:0/C24:0), Cer(C18:0/C24:0), Cer(C18:0/C24:0), Cer(C22:0/C24:0), and Cer(C24:1/C24:0), along with higher Cer C16:0, C18:0, C20:0, C22:0, and Cer C24:1 individually with increased cardiovascular mortality in ambulatory patients with chronic HF. Here, CBLN1 is linked to hydrops fetalis.
