The aim of this study was to evaluate the association between serum copper (S -Cu) levels and the risk of a first event of cardiovascular disease (CVD) in a population of older adults with high cardiovascular risk. Methods and results: We conducted a case-control study nested within the PREDIMED trial. During a median follow-up of 4.8 years, a total of 207 incident cases diagnosed with CVD were matched for sex, age, and intervention group with 436 controls. Personal interviews, reviews of medical records, and validated questionnaires were used to assess known CVD risk factors. Biological serum samples were collected annually. Inductively coupled plasma mass spectrometry analysis was used to determine S-Cu levels. Adjusted odds ratios were calculated using multivariate conditional logistic regression models. All participants had S-Cu levels within the reference values, 750 mg/L to 1450 mg/L. Among men, but not among women, the mean S-Cu concentration was higher in cases 1014.1 mg/L than in controls 959.3 mg/L; (p = 0.004). In men, the multivariable-adjusted odds ratio for CVD was 2.36 (95% CI 1.07-5.20 for the comparison of the highest vs. the lowest quartile; p for trend = 0.02), in women, it was 0.43 (95% CI 0.11-1.70; p for trend = 0.165). Conclusion: In older Spanish men with high cardiovascular risk, a significant association was observed between high S-Cu levels, but still within the reference values, and an increased risk of a first event of CVD. Our findings suggest a sex difference in CVD risk and S-Cu levels. To confirm this relationship and to analyze the differences observed between men and women, further studies are needed.}, organization = {Spanish government, Instituto de Salud Carlos III (ISCIII)}, organization = {Centro de Investigación Biomedica en Red de Fisiopatología de la Obesidad y Nutrición (CIBERobn) RTIC G03/140, RTIC RD 06/0045, JR14/00008}, organization = {Centro Nacional de Investigaciones Cardiovasculares}, organization = {Fondo de Investigación Sanitaria-Fondo Europeo de Desarrollo Regional CNIC06/2007}, organization = {Instituto de Salud Carlos III Spanish Government PI04-2239, PI05/2584, CP06/00100, PI07/0240, PI07/1138, PI07/0954, PI 07/0473, PI10/01407, PI10/02658, PI11/01647, P11/02505, PI13/00462,}, organization = {Ministerio de Economia y Competitividad-Fondos FEDER-Instituto de Salud Carlos III 2009-13906-C02, AGL2010-22319-C03, AGL2013-49083C3-1-R}, organization = {Fundacion Mapfre UNGR15-CE-3380}, organization = {Consejería de Salud de la Junta de Andalucía}, organization = {Public Health Division of the Department of Health of the Autonomous Government of Catalonia PI0105/2007}, organization = {Center for Forestry Research & Experimentation (CIEF)}, organization = {Conselleria de Sanitat y AP 06109, GVACOMP2010-181, GVACOMP2011-151}, organization = {Atención Primaria (CS) 2010-AP-111, CS2011-AP-042}, organization = {onal Government of Navarra 2010-AP-111, CS2011-AP-042}, organization = {Centre Catala de la Nutricio de l'Institut d'Estudis Catalans P27/2011}, organization = {Universidad de Málaga/ Consorcio de Bibliotecas Universitarias de Andalucía (CBUA)}, organization = {Real Academia de Medicina de Andalucía Oriental}, publisher = {Elsevier}, keywords = {Serum copper}, keywords = {Trace elements}, keywords = {Cardiovascular disease}, keywords = {Infarction}, keywords = {Stroke}, keywords = {PREDIMED}, title = {Association between serum copper levels and risk of cardiovascular disease: A nested case-control study in the PREDIMED trial}, doi = {10.1016/j.numecd.2023.07.008}, author = {Muñoz-Bravo, Carlos and Olmedo Palma, Pablo and Gil Hernández, Fernando}, }
