Abstract Background: Aspirin is the key treatment in the secondary prevention of atherosclerotic cardiovascular disease. High on-treatment platelet reactivity (HTPR) to aspirin has been reported to partially account for the enhanced risk of thrombotic events. In particular, HTPR has been described more frequently among elderly patients. The aim of this study was to identify the clinical and biological factors associated with HTPR in a real-life elderly population.Methods: In this retrospective study, elderly patients with atherosclerotic cardiovascular disease on regular aspirin treatment were enrolled. Cardiovascular risk factors, routine biological parameters, comorbidities, and concomitant medications were recorded. The upper quartile of the platelet aggregation rate, determined by light transmission aggregometry with arachidonic acid, was defined as the HTPR group.Results: A total of 304 patients were included (mean age 77 ± 8 years, 76% men). Patients in the HTPR group were older than the patients in the non-HTPR group (mean age: 79 ± 7 vs. 76 ± 8 years, p = 0.008). Patients with moderately decreased estimated glomerular filtration rate (eGFR) had a higher frequency of HTPR than patients with slightly decreased eGFR or normal eGFR (35.8%, 22.5%, 12.2%, respectively, p < 0.05). In multivariate analysis, an independent risk factor for HTPR was the eGFR (OR: 0.984, 95% CI: 0.980-0.988, p < 0.001).Conclusions: Advanced age and decreased eGFR are correlated with poor pharmacodynamic response to aspirin. Antiplatelet strategy in elderly patients with atherosclerotic cardiovascular disease should be driven by an individualized approach, especially in patients with impaired renal function.

Abstract Objectives Trimethylamine N-oxide (TMAO) is a gut microbiota-dependent metabolite of dietary choline, L-carnitine and phosphatidylcholine-rich animal foods. Based on experimental studies and cohorts with prevalent disease, elevated TMAO may increase risk of atherosclerotic cardiovascular disease (ASCVD). TMAO is also renally cleared and may interact with and causally contribute to renal dysfunction and elevated cystatin-C. Yet, the associations of serial TMAO levels with incident ASCVD in a community-based prospective cohort, and the potential mediating and modifying role of renal function, are not established. Methods We investigated the associations of serial measures of plasma TMAO, assessed at baseline and 7 years post baseline, with incident ASCVD among 4144 older adults in the Cardiovascular Health Study (CHS). TMAO was measured using stable isotope dilution LC/MS/MS (lab CV &lt;6%). Incident ASCVD (myocardial infarction, fatal coronary heart disease, stroke, sudden cardiac death, or other atherosclerotic death) was centrally adjudicated using medical records. Risk was assessed by multivariable Cox proportional hazards regression including time-varying demographics, lifestyle factors, medical history, and laboratory and dietary variables. We assessed potential mediating effects and interaction by renal function estimated by cystatin-C. Results During a median 15 years follow-up, 1757 ASCVD events occurred. After multivariable adjustment, TMAO was associated with a higher risk of ASCVD, with an extreme quintile HR (95% CI) of 1.22 (1.04, 1.44), P-trend = 0.01. This relationship appeared further mediated or confounded by estimated glomerular filtration rate (eGFR): adjusting for cystatin-C-based eGFR, the HR (95% CI) was 1.06 (0.98–1.25). Significant interaction was also observed by renal function (P-interaction &lt; 0.001), with TMAO associated with higher risk of ASCVD among individuals with impaired renal function (eGFR ≤ 60) [1.63 (1.03–2.59)], but not normal baseline renal function (eGFR &gt; 60) [1.15 (0.96–1.37)], even with further adjustment for continuous eGFR. Conclusions In this large community-based cohort of older US adults, higher serial measures of TMAO were associated with an elevated risk of ASCVD, in particular among those with impaired renal function.

Background Trimethylamine N‐oxide (TMAO) is a gut microbiota‐dependent metabolite of dietary choline, L‐carnitine, and phosphatidylcholine‐rich foods. On the basis of experimental studies and patients with prevalent disease, elevated plasma TMAO may increase risk of atherosclerotic cardiovascular disease (ASCVD). TMAO is also renally cleared and may interact with and causally contribute to renal dysfunction. Yet, how serial TMAO levels relate to incident and recurrent ASCVD in community‐based populations and the potential mediating or modifying role of renal function are not established. Methods and Results We investigated associations of serial measures of plasma TMAO, assessed at baseline and 7 years, with incident and recurrent ASCVD in a community‐based cohort of 4131 (incident) and 1449 (recurrent) older US adults. TMAO was measured using stable isotope dilution liquid chromatography–tandem mass spectrometry (laboratory coefficient of variation, <6%). Incident ASCVD (myocardial infarction, fatal coronary heart disease, stroke, sudden cardiac death, or other atherosclerotic death) was centrally adjudicated using medical records. Risk was assessed by multivariable Cox proportional hazards regression, including time‐varying demographics, lifestyle factors, medical history, laboratory measures, and dietary habits. Potential mediating effects and interaction by estimated glomerular filtration rate (eGFR) were assessed. During prospective follow‐up, 1766 incident and 897 recurrent ASCVD events occurred. After multivariable adjustment, higher levels of TMAO were associated with a higher risk of incident ASCVD, with extreme quintile hazard ratio (HR) compared with the lowest quintile=1.21 (95% CI, 1.02–1.42; P ‐trend=0.029). This relationship appeared mediated or confounded by eGFR (eGFR‐adjusted HR, 1.07; 95% CI, 0.90–1.27), as well as modified by eGFR ( P ‐interaction <0.001). High levels of TMAO were associated with higher incidence of ASCVD in the presence of impaired renal function (eGFR <60 mL/min per 1.73 m 2 : HR, 1.56 [95% CI, 1.13–2.14]; P ‐trend=0.007), but not normal or mildly reduced renal function (eGFR ≥60 mL/min per 1.73 m 2 : HR, 1.03 [95% CI, 0.85–1.25]; P ‐trend=0.668). Among individuals with prior ASCVD, TMAO associated with higher risk of recurrent ASCVD (HR, 1.25 [95% CI, 1.01–1.56]; P ‐trend=0.009), without significant modification by eGFR. Conclusions In this large community‐based cohort of older US adults, serial measures of TMAO were associated with higher risk of incident ASCVD, with apparent modification by presence of impaired renal function and with higher risk of recurrent ASCVD.

Ascvd Risk

American Indians (AI) have a high prevalence of diabetes, obesity, cardiovascular disease (CVD), and chronic kidney disease. Inclusion of kidney function and other population-specific characteristics in equations used to predict atherosclerotic CVD (ASCVD) risk may help define risk more accurately in populations with these chronic diseases. We used data from the Strong Heart Study (SHS), a population-based longitudinal cohort study of AI, to modify the American College of Cardiology/American Heart Association (ACC/AHA) Pooled Cohort ASCVD risk equations and then explored the performance of the new equations in predicting ASCVD in AI. The study included baseline SHS exam data from 4213 individuals between 45 and 75 years of age, collected in 13 communities from 3 geographic areas in the United States and spanning a wide range of tribal backgrounds, with continuous follow-up data from 1989 to 2015. Using SHS data for blood pressure, diabetes, cholesterol, smoking, and renal function, Cox proportional hazard models were developed to predict ASCVD-free time for AI men and women. ASCVD risk in AI calculated using the SHS-modified equations were compared to risk calculated using the ACC/AHA pooled cohort equations for African Americans (AAs) and Whites. Goodness-of-fit measures for ASCVD risk prediction showed that the SHS-modified equations fit the data from the SHS better than the ACC/AHA equations for AAs and Whites. Adjusting risk prediction equations using population data from the SHS and including measures of renal function significantly improved ASCVD risk prediction in our AI cohort.
