Trimethylamine-N-oxide (TMAO), a microbiota-associated metabolite, is associated with cardiovascular (CV) events in various populations (1), including patients with chronic heart failure (HF) (2,3).Additional adjustments for body mass index, New York Heart Association functional class, N-terminal pro-brain natriuretic peptide (NT-proBNP), estimated glomerular filtration rate (eGFR), smoking, hypertension, coronary artery disease, diabetes mellitus, and atrial fibrillation (model 2) and further adjustment for high-sensitivity C-reactive protein (model 3) did not affect the significant association of TMAO with mortality.The authors also thank the LURIC study team members who were either temporarily or permanently involved in patient recruitment and sample and data handling; the laboratory staff at the Ludwigshafen General Hospital; and the Universities of Freiburg, Ulm, and Graz. 1 W.H.
