Abstract 019: Changes in Gut Microbial Metabolites and Risk of Coronary Heart Disease in US Women: the Nurses’ Health Study

Introduction: Circulating levels of gut microbial metabolites, trimethylamine N-oxide (TMAO) and its nutrient precursors of choline and L-carnitine, have been suggested as risk factors for coronary heart disease (CHD). Whether changes in gut microbial metabolites are associated with the CHD incidence remains unknown. Hypothesis: We assessed the hypothesis that long-term (over 10 years) changes in plasma levels of TMAO, choline, and L-carnitine...
