- Background: The relevance of blood lipid concentrations to long-term incidence of cardiovascular disease and the relevance of lipid-lowering therapy for cardiovascular disease outcomes is unclear. We investigated the cardiovascular disease risk associated with the full spectrum of bloodstream non-HDL cholesterol concentrations. We also created an easy-to-use tool to estimate the long-term probabilities for a cardiovascular disease event associated with non-HDL cholesterol and modelled its risk reduction by lipid-lowering treatment.Methods: In this risk-evaluation and risk-modelling study, we used Multinational Cardiovascular Risk Consortium data from 19 countries across Europe, Australia, and North America. Individuals without prevalent cardiovascular disease at baseline and with robust available data on cardiovascular disease outcomes were included. The primary composite endpoint of atherosclerotic cardiovascular disease was defined as the occurrence of the coronary heart disease event or ischaemic stroke. Sex-specific multivariable analyses were computed using non-HDL cholesterol categories according to the European guideline thresholds, adjusted for age, sex, cohort, and classical modifiable cardiovascular risk factors. In a derivation and validation design, we created a tool to estimate the probabilities of a cardiovascular disease event by the age of 75 years, dependent on age, sex, and risk factors, and the associated modelled risk reduction, assuming a 50% reduction of non-HDL cholesterol.Findings: Of the 524 444 individuals in the 44 cohorts in the Consortium database, we identified 398 846 individuals belonging to 38 cohorts (184 055 [48·7%] women; median age 51·0 years [IQR 40·7–59·7]). 199 415 individuals were included in the derivation cohort (91 786 [48·4%] women) and 199 431 (92 269 [49·1%] women) in the validation cohort. During a maximum follow-up of 43·6 years (median 13·5 years, IQR 7·0–20·1), 54 542 cardiovascular endpoints occurred. Incidence curve analyses showed progressively higher 30-year cardiovascular disease event-rates for increasing non-HDL cholesterol categories (from 7·7% for non-HDL cholesterol <2·6 mmol/L to 33·7% for ≥5·7 mmol/L in women and from 12·8% to 43·6% in men; p<0·0001). Multivariable adjusted Cox models with non-HDL cholesterol lower than 2·6 mmol/L as reference showed an increase in the association between non-HDL cholesterol concentration and cardiovascular disease for both sexes (from hazard ratio 1·1, 95% CI 1·0–1·3 for non-HDL cholesterol 2·6 to <3·7 mmol/L to 1·9, 1·6–2·2 for ≥5·7 mmol/L in women and from 1·1, 1·0–1·3 to 2·3, 2·0–2·5 in men). The derived tool allowed the estimation of cardiovascular disease event probabilities specific for non-HDL cholesterol with high comparability between the derivation and validation cohorts as reflected by smooth calibration curves analyses and a root mean square error lower than 1% for the estimated probabilities of cardiovascular disease. A 50% reduction of non-HDL cholesterol concentrations was associated with reduced risk of a cardiovascular disease event by the age of 75 years, and this risk reduction was greater the earlier cholesterol concentrations were reduced.Interpretation: Non-HDL cholesterol concentrations in blood are strongly associated with long-term risk of atherosclerotic cardiovascular disease. We provide a simple tool for individual long-term risk assessment and the potential benefit of early lipid-lowering intervention. These data could be useful for physician–patient communication about primary prevention strategies.

- Objectives:Secretoneurin is associated with cardiomyocyte Ca2+ handling and improves risk prediction in patients with acute myocardial dysfunction. Whether secretoneurin improves risk assessment on top of established cardiac biomarkers and European System for Cardiac Operative Risk Evaluation II in patients undergoing cardiac surgery is not known.Design:Prospective, observational, single-center sub-study of a multicenter study.Setting:Prospective observational study of survival in patients undergoing cardiac surgery.Patients:A total of 619 patients undergoing cardiac surgery.Interventions:Patients underwent either isolated coronary artery bypass graft surgery, single noncoronary artery bypass graft surgery, two procedures, or three or more procedures. Procedures other than coronary artery bypass graft were valve surgery, surgery on thoracic aorta, and other cardiac surgery.Measurements and Main Results:We measured preoperative and postoperative secretoneurin concentrations and adjusted for European System for Cardiac Operative Risk Evaluation II, N-terminal pro-B-type natriuretic peptide, and cardiac troponin T concentrations in multivariate analyses. During 961 days of follow- up, 59 patients died (9.5%). Secretoneurin concentrations were higher among nonsurvivors compared with survivors, both before (168 pmol/L [quartile 1-3, 147-206 pmol/L] vs 160 pmol/L [131-193 pmol/L]; p = 0.039) and after cardiac surgery (173 pmol/L [129-217 pmol/L] vs 143 pmol/L [111-173 pmol/L]; p < 0.001). Secretoneurin concentrations decreased from preoperative to postoperative measurements in survivors, whereas we observed no significant decrease in secretoneurin concentrations among nonsurvivors. Secretoneurin concentrations were weakly correlated with established risk indices. Patients with the highest postoperative secretoneurin concentrations had worse outcome compared with patients with lower secretoneurin concentrations (p < 0.001 by the log-rank test) and postoperative secretoneurin concentrations were associated with time to death in multivariate Cox regression analysis: hazard ratio ln secretoneurin 2.96 (95% CI, 1.46-5.99; p = 0.003). Adding postoperative secretoneurin concentrations to European System for Cardiac Operative Risk Evaluation II improved patient risk stratification, as assessed by the integrated discrimination index: 0.023 (95% CI, 0.0043-0.041; p = 0.016).Conclusions:Circulating postoperative secretoneurin concentrations provide incremental prognostic information to established risk indices in patients undergoing cardiac surgery.

- BACKGROUND: We examined whether secretoneurin (SN), a biomarker associated with cardiomyocyte Ca2+ handling, provides prognostic information in patients with acute respiratory failure (ARF).METHODS: We included 490 patients with ARF, defined as ventilatory support >6 h, with blood samples available on admission to the intensive care unit (ICU). SN concentrations were measured by RIA.RESULTS: A total of 209 patients (43%) were hospitalized with cardiovascular (CV)-related ARF, and 90-day mortality rates were comparable between CV- and non CV-related ARF (n = 281): 31% vs 24%, P = 0.11. Admission SN concentrations were higher in nonsurvivors than in survivors in both CV -related (median 148 [quartile 1-3, 117-203] vs 108 [87-143] pmol/L, P < 0.001) and non CV-related ARF (139 [115-184] vs 113 [91-139] pmol/L, P < 0.001). In patients with CV -related ARF, SN concentrations on ICU admission were associated with 90-day mortality [odds ratio (OR) 1.97 (95% CI, 1.04-3.73, P = 0.04)] after adjusting for established risk indices, including N-terminal-pro-B-type natriuretic peptide (NT-proBNP) concentrations. SN also improved patient classification in CV -related ARF as assessed by the net reclassification index: 0.32 (95% CI, 0.04-0.59), P = 0.03. The area under the curve (AUC) of SN to predict mortality in patients with CV -related ARF was 0.72 (95% CI, 0.65-0.79), and the AUC of NT-proBNP was 0.64 (0.56-0.73). In contrast, SN concentrations on ICU admission did not provide incremental prognostic value to established risk indices in patients with non CV-related ARF, and the AUC was 0.67 (0.60-0.75).CONCLUSIONS: SN concentrations measured on ICU admission provided incremental prognostic information to established risk indices in patients with CV -related ARF, but not in patients with non CV-related ARF.
