Frailty status was determined using a frailty index constructed with 48 variables according to the cumulative deficits model. Physical frailty and cognitive frailty were also assessed in detail. Fasting plasma TMAO was measured by mass spectrometry.Results: The proportion of frail subjects was 29.9% (135/451). Plasma TMAO levels were significantly higher in frail patients than in nonfrail individuals (4.04 [2.84– 7.01] vs 3.21 [2.13– 5.03] μM; p< 0.001). Elevated plasma TMAO levels were independently associated with the likelihood of frailty (OR 2.12, 95% CI 1.01– 4.38, p=0.046). Dose–response analysis revealed a linear association between the TMAO concentration and the OR for frailty. A 2-unit increase in TMAO was independently correlated with physical frailty (OR 1.23, 95% CI 1.08– 1.41, p for trend 0.002) and cognitive frailty (OR 1.21, 95% CI 1.01– 1.45, p for trend 0.04).Conclusion: Elevated circulating TMAO levels are independently associated with frailty among older adults with cardiovascular disease.Keywords: older adults, frailty, TMAO, cardiovascular disease, physical frailty, cognitive frailtyHe WLuo YLiu JPSun NGuo DCui LLZheng PPYao SMYang JFWang HDove Medical Pressarticleolder adultsfrailtytmaocardiovascular diseasephysical frailtycognitive frailtyGeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 15, Pp 1809-1820 (2020)
