- Importance: Inflammation promotes cardiovascular disease and anti-inflammatory treatment reduces cardiovascular events in patients with chronic coronary syndrome. Chronic kidney disease (CKD) is a risk factor for cardiovascular disease. It is unclear how inflammation mediated by interleukin 6 (IL-6) in patients with CKD is linked to cardiovascular disease.Objective: To investigate associations between IL-6 and cardiovascular outcomes in patients with chronic coronary syndrome in association with kidney function.Design, Setting, and Participants: This multicenter cohort study included patients enrolled at 663 centers in 39 countries with chronic coronary syndrome who were included in the Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy (STABILITY) trial. Patients were enrolled between December 2008 and April 2010 and were followed up for a median length of 3.7 years. Analysis in this substudy began September 2020.Exposures: Exposures were IL-6 and creatinine estimated glomerular filtration rates (eGFR), which were collected at baseline. Associations between continuous and categorical levels (<2.0 ng/L vs ≥2.0 ng/L) of IL-6 and cardiovascular outcomes were tested in association with eGFR cutoffs (normal eGFR level [≥90 mL/min/1.73 m2], mildly decreased eGFR level [60-90 mL/min/1.73 m2], and moderately to severely decreased eGFR level [<60 mL/min/1.73 m2]).Main Outcomes and Measures: Main outcome was major adverse cardiovascular events (MACE), a composite of cardiovascular death, myocardial infarction, and stroke.Results: This substudy of the STABILITY trial included 14 611 patients with available IL-6 levels at baseline. The median (interquartile range) age was 65 (59-71) years, and 2700 (18.5%) were female. During follow-up, MACE occurred in 1459 individuals (10.0%). Higher levels of IL-6 were in continuous models independently associated with risk of MACE (P < .001) in all CKD strata. Using predefined strata, elevated IL-6 level (≥2.0 vs <2.0 ng/L) was associated with increased risk of MACE at normal kidney function (2.9% vs 1.9% events/y [hazard ratio, 1.35; 95% CI, 1.02-1.78]), mild CKD (3.3% vs 1.9% [hazard ratio, 1.57; 95% CI, 1.35-1.83]), and moderate to severe CKD (5.0% vs 2.9% [hazard ratio, 1.60; 95% CI, 1.28-1.99]).Conclusions and Relevance: In patients with chronic coronary syndrome, elevated levels of IL-6 were associated with risk of MACE in all CKD strata. Thus, IL-6 and CKD stage may help when identifying patients with chronic coronary syndrome for anti-inflammatory treatment.

- BACKGROUND: Higher growth differentiation factor 15 (GDF-15) concentrations are associated with cardiovascular (CV) and non-CV morbidity and mortality. However, information on associations between GDF-15 and the risk of specific CV and non-CV events in stable coronary heart disease (CHD) patients is limited.METHODS: In 14 577 patients with stable CHD participating in the Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy Trial (STABILITY), GDF-15 and other prognostic biomarkers (N-terminal pro-B-type natriuretic peptide, high-sensitivity troponin T, cystatin C, and high-sensitivity C-reactive protein) were measured. In adjusted Cox regression models, the associations between GDF-15 and the composite CV end point [CV death, myocardial infarction (MI), and stroke], as well as other CV and non-CV events, were assessed.RESULTS: The median concentration (interquartile range) of GDF-15 at baseline was 1253 (915-1827) ng/L. The hazard ratio for the composite end point for the highest compared to the lowest quartile of GDF-15 was 1.8 (95% CI, 1.5-2.2); for CV death, 2.63 (1.9-3.6); for sudden death, 3.06 (1.9-4.8); for heart failure (HF) death, 4.3 (1.3-14); for cancer death, 2.5 (1.3-4.7); for hospitalization for HF, 5.8 (3.2-10); for MI 1.4 (95% CI, 1.1-1.9); and for stroke, 1.8 (95% CI, 1.1-2.8). After adjustment for other prognostic biomarkers, GDF-15 remained significantly associated with all outcomes except for MI.CONCLUSIONS: In stable CHD, GDF-15 was independently associated with CV, non-CV, and cancer mortality, as well as with MI and stroke. When also adjusting for other prognostic biomarkers, the associations to all fatal and nonfatal events were maintained except for MI. Information on GDF-15, therefore, might be helpful when assessing the risk of adverse outcomes in patients with stable CHD. ClinicalTrials.gov Identifier: NCT00799903.

- Background Currently, there is no generally accepted model to predict outcomes in stable coronary heart disease (CHD).Objectives This study evaluated and compared the prognostic value of biomarkers and clinical variables to develop a biomarker-based prediction model in patients with stable CHD.Methods In a prospective, randomized trial cohort of 13,164 patients with stable CHD, we analyzed several candidate biomarkers and clinical variables and used multivariable Cox regression to develop a clinical prediction model based on the most important markers. The primary outcome was cardiovascular (CV) death, but model performance was also explored for other key outcomes. It was internally bootstrap validated, and externally validated in 1,547 patients in another study.Results During a median follow-up of 3.7 years, there were 591 cases of CV death. The 3 most important biomarkers were N-terminal pro–B-type natriuretic peptide (NT-proBNP), high-sensitivity cardiac troponin T (hs-cTnT), and low-density lipoprotein cholesterol, where NT-proBNP and hs-cTnT had greater prognostic value than any other biomarker or clinical variable. The final prediction model included age (A), biomarkers (B) (NT-proBNP, hs-cTnT, and low-density lipoprotein cholesterol), and clinical variables (C) (smoking, diabetes mellitus, and peripheral arterial disease). This “ABC-CHD” model had high discriminatory ability for CV death (c-index 0.81 in derivation cohort, 0.78 in validation cohort), with adequate calibration in both cohorts.Conclusions This model provided a robust tool for the prediction of CV death in patients with stable CHD. As it is based on a small number of readily available biomarkers and clinical factors, it can be widely employed to complement clinical assessment and guide management based on CV risk.

- BACKGROUND Recommendations for physical activity in patients with stable coronary heart disease (CHD) are based on modest evidence.OBJECTIVES The authors analyzed the association between self-reported exercise and mortality in patients with stable CHD.METHODS A total of 15,486 patients from 39 countries with stable CHD who participated in the STABILITY (Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy) study completed questions at baseline on hours spent each week taking mild, moderate, and vigorous exercise. Associations between the volume of habitual exercise in metabolic equivalents of task hours/week and adverse outcomes during a median follow-up of 3.7 years were evaluated.RESULTS A graded decrease in mortality occurred with increased habitual exercise that was steeper at lower compared with higher exercise levels. Doubling exercise volume was associated with lower all-cause mortality (unadjusted hazard ratio [HR]: 0.82; 95% confidence interval [CI]: 0.79 to 0.85; adjusting for covariates, HR: 0.90; 95% CI: 0.87 to 0.93). These associations were similar for cardiovascular mortality (unadjusted HR: 0.83; 95% CI: 0.80 to 0.87; adjusted HR: 0.92; 95% CI: 0.88 to 0.96), but myocardial infarction and stroke were not associated with exercise volume after adjusting for covariates. The association between decrease in mortality and greater physical activity was stronger in the subgroup of patients at higher risk estimated by the ABC-CHD (Age, Biomarkers, Clinical-Coronary Heart Disease) risk score (p for interaction = 0.0007).CONCLUSIONS In patients with stable CHD, more physical activity was associated with lower mortality. The largest benefits occurred between sedentary patient groups and between those with the highest mortality risk.

- Background-—The major determinants and prognostic importance of self-reported health in patients with stable coronary heartdisease are uncertain.Methods and Results-—The STABILITY (Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy) trialrandomized 15 828 patients with stable coronary heart disease to treatment with darapladib or placebo. At baseline, 98% ofparticipants completed a questionnaire that included the question, “Overall, how do you feel your general health is now?”Possible responses were excellent, very good, good, average, and poor. Adjudicated major adverse cardiac events, whichincluded cardiovascular death, myocardial infarction, and stroke, were evaluated by Cox regression during 3.7 years of follow-upfor participants who reported excellent or very good health (n=2304), good health (n=6863), and average or poor health(n=6361), before and after adjusting for 38 covariates. Self-reported health was most strongly associated with geographicregion, depressive symptoms, and low physical activity (P<0.0001 for all). Poor/average compared with very good/excellentself-reported health was independently associated with major adverse cardiac events (hazard ratio [HR]: 2.30 [95% confidenceinterval (CI), 1.92–2.76]; adjusted HR: 1.83 [95% CI, 1.51–2.22]), cardiovascular mortality (HR: 4.36 [95% CI, 3.09–6.16];adjusted HR: 2.15 [95% CI, 1.45–3.19]), and myocardial infarction (HR: 1.87 [95% CI, 1.46–2.39]; adjusted HR: 1.68 [95% CI,1.25–2.27]; P<0.0002 for all).Conclusions-—Self-reported health is strongly associated with geographical region, mood, and physical activity. In a globalcoronary heart disease population, self-reported health was independently associated with major cardiovascular events andmortality beyond what is measurable by established risk indicators.

- Background:Underlying mechanisms behind the hypothesized relationship between periodontal disease (PD) and coronary heart disease (CHD) have been insufficiently explored. We evaluated associations between self-reported tooth loss-a marker of PD- and prognostic biomarkers in 15,456 (97%) patients with stable CHD in the global STABILITY trial.Methods and results:Baseline blood samples were obtained and patients reported their number of teeth according to the following tooth loss levels: "26-32 (All)" [lowest level], "20-25", "15-19", "1-14", and "No Teeth" [highest level]. Linear and Cox regression models assessed associations between tooth loss levels and biomarker levels, and the relationship between tooth loss levels and outcomes, respectively.After multivariable adjustment, the relative biomarker increase between the highest and the lowest tooth loss level was: high-sensitivity C-reactive protein 1.21 (95% confidence interval, 1.14-1.29), interleukin 6 1.14 (1.10-1.18), lipoprotein-associated phospholipase A(2) activity 1.05 (1.03-1.06), growth differentiation factor 15 1.11 (1.08-1.14), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) 1.18 (1.11-1.25). No association was detected for high-sensitivity troponin T 1.02 (0.98-1.05). Some attenuation of the relationship between tooth loss and outcomes resulted from the addition of biomarkers to the multivariable analysis, of which NT-proBNP had the biggest impact.Conclusions:A graded and independent association between tooth loss and several prognostic biomarkers was observed, suggesting that tooth loss and its underlying mechanisms may be involved in multiple pathophysiological pathways also implicated in the development and prognosis of CHD. The association between tooth loss and cardiovascular death and stroke persisted despite comprehensive adjustment including prognostic biomarkers.

- Aim There are reported links between periodontal disease (PD) and cardiovascular (CV) risk but data are lacking, especially from populations with established coronary heart disease (CHD). This study describes self-reported indicators of PD and associations with CV risk factors in a global stable CHD population.Methods and results A total of 15,828 participants in the global STABILITY trial underwent a physical examination, blood sampling, and completed a lifestyle questionnaire. They reported remaining number of teeth (none, 1–14, 15–20, 21–25 or 26–32 (all)) and frequency of gum bleeding (never/rarely, sometimes, often or always). Adjusted linear and logistic regression models assessed associations between tooth loss, gum bleeding, and socioeconomic and CV risk factors.A total of 40.9% of participants had <15 remaining teeth; 16.4% had no teeth; and 25.6% reported gum bleeding with large differences in prevalence among countries, regions and ethnic groups. Less tooth loss was associated with lower levels of glucose, low-density lipoprotein (LDL) cholesterol, systolic blood pressure, waist circumference and hs-CRP; higher estimated glomerular filtration rate; decreased odds for diabetes and smoking, and increased odds for higher education, alcohol consumption and work stress. Gum bleeding was associated with higher LDL cholesterol and systolic blood pressure; decreased odds for smoking, but increased odds for higher education, alcohol consumption and stress.Conclusion Self-reported indicators of PD were common in this chronic CHD population and were associated with an increasing socioeconomic and CV risk factor burden. However, causality between self-reported PD and CV risk and outcome needs further investigation.
