N1 - Funding Information:
Acknowledgments We thank the assistant research team who has performed the study recruitment of PPS-3 (Paris Prospective Study III) participants, the medical, and technical staff of the Centre d'Investigations Préventives et Cliniques (IPC), and the Platform for Biological Resources (PRB) of the Hôpital Européen Georges Pompidou for the management of the biobank. We also thank the staff of the Cochin Cytometry and Immunobiology core facility (CYBIO) for the measurements of CRP (Creactive protein), IL (interleukin)-6, NT-proBNP (N-terminal pro-brain natriuretic peptide), and troponin I. We thank the assistant research team of PPS-3 including R. Bentaleb and M. Pernet for performing the follow-up of the participants. PPS- 3 is organized under an agreement between Institut National de la Santé et de la Recherche Médicale (INSERM) and the IPC Center and between INSERM and the Resources Biologiques de l'Hôpital European Georges Pompidou, Paris, France. We also thank the Caisse Nationale d'Assurance Maladie des Travailleurs Salariés (CNAM-TS, France) and the Caisse Primaire d'Assurance Maladie de Paris (CPAM-P, France) for helping make this study possible. Sources of Funding The PPS-3 (Paris Prospective Study III) was supported by grants from The National Research Agency (ANR), the Research Foundation for Hypertension (RFHTA), the Research Institute in Public Health (IRESP), the Region Ile de France (Domaine d'Intérêt Majeur), and a European Horizon H2020 grant.

N2 - BACKGROUND: To examine the association of ultrasensitive cTnI (cardiac troponin I) with incident cardiovascular disease events (CVDs) in the primary prevention setting.METHODS: cTnI was analyzed in the baseline plasma (2008-2012) of CVD-free volunteers from the Paris Prospective Study III using a novel ultrasensitive immunoassay (Simoa Troponin-I 2.0 Kit, Quanterix, Lexington) with a limit of detection of 0.013 pg/mL. Incident CVD hospitalizations (coronary heart disease, stroke, cardiac arrhythmias, deep venous thrombosis or pulmonary embolism, heart failure, or arterial aneurysm) were validated by critical review of the hospital records. Hazard ratios were estimated per log-transformed SD increase of cTnI in Cox models using age as the time scale.RESULTS: The study population includes 9503 participants (40% women) aged 59.6 (6.3) years. cTnI was detected in 99.6% of the participants (median value=0.63 pg/mL, interquartile range, 0.39-1.09). After a median follow-up of 8.34 years (interquartile range, 8.0-10.07), 516 participants suffered 612 events. In fully adjusted analysis, higher cTnI (per 1 SD increase of log cTnI) was significantly associated with CVD events combined (hazard ratio, 1.18 [1.08-1.30]). Among all single risk factors, cTnI had the highest discrimination capacity for incident CVD events (C index=0.6349). Adding log cTnI to the SCORE 2 (Systematic Coronary Risk Evaluation) risk improved moderately discriminatory capacity (C index 0.698 versus 0.685; bootstrapped C index difference: 0.0135 [95% CI, 0.0131-0.0138]), and reclassification of the participants (categorical net reclassification index, 0.0628 [95% CI, 0.023-0.102]). Findings were consistent using the US pooled cohort risk equation.CONCLUSIONS: Ultrasensitive cTnI is an independent marker of CVD events in the primary prevention setting.
