摘要：Plasma Trimethylamine-
N-oxide (TMAO), a gut microbiota metabolite from dietary phosphatidylcholine, is mechanistically linked to cardiovascular disease (CVD) and adverse cardiovascular events. We aimed to examine the relationship between plasma TMAO levels and subclinical myocardial damage using high-sensitivity cardiac troponin-T (hs-cTnT). We studied 134 patients for whom TMAO data were available from the Cohort Of patients at a high Risk of Cardiovascular Events—Thailand (CORE-Thailand) registry, including 123 (92%) patients with established atherosclerotic disease and 11 (8%) with multiple risk factors. Plasma TMAO was measured by NMR spectroscopy. In our study cohort (mean age 64 ± 8.9 years; 61% men), median TMAO was 3.81 μM (interquartile range [IQR
