Popis: | Objective— Gut microbiota–dependent metabolites, in particular trimethylamine N -oxide (TMAO), have recently been reported to promote atherosclerosis and thrombosis. Here, we examined for the first time the relation of TMAO and the risk of incident cardiovascular events in patients with recent first-ever ischemic stroke in 2 independent prospective cohorts. Moreover, the link between TMAO and proinflammatory monocytes as a potential contributing factor for cardiovascular risk in stroke patients was studied. Approach and Results— In a first study (n=78), higher TMAO plasma levels were linked with an increased risk of incident cardiovascular events including myocardial infarction, recurrent stroke, and cardiovascular death (fourth quartile versus first quartile; hazard ratio, 2.31; 95% CI, 1.25–4.23; P P P =0.04). A significant correlation was also found between TMAO levels and percentage of proinflammatory intermediate CD14 ++ CD16 + monocytes ( r =0.70; P high monocytes were higher than in the chow-fed control group (choline: 9.2±0.5×10 3 per mL versus control: 6.5±0.5×10 3 per mL; P 3 per mL; P Conclusions— The present study demonstrates for the first time a graded relation between TMAO levels and the risk of subsequent cardiovascular events in patients with recent prior ischemic stroke. Our data support the notion that TMAO-related increase of proinflammatory monocytes may add to elevated cardiovascular risk of patients with increased TMAO levels. |
