PURPOSE:Copeptin and insulin-like growth factor binding protein-1 analysed at admission for a myocardial infarction in patients with type 2 diabetes mellitus predicts cardiovascular events. The present aim was to study the association between copeptin and insulin-like growth factor binding protein-1, the development of the levels over time, and if the predictive value remained when measured at hospital discharge and 3 months thereafter. METHODS:Copeptin and insulin-like growth factor binding protein-1 were analysed in patients (median age = 70, male = 68%) with type 2 diabetes mellitus + myocardial infarction at admission (n = 393), discharge (n = 309) and 3 months later (n = 288). The primary endpoint was cardiovascular event (cardiovascular death/non-fatal myocardial infarction/stroke) with the three time points as separate baselines. RESULTS: The median copeptin levels were 21.8 pmol/L at admission, 8.5 pmol/L at discharge and 8.4 pmol/L after 3 months, while insulin-like growth factor binding protein-1 levels continued to increase. There were significant correlations between the biomarkers at all occasions. During an average follow-up of 2.5 years, copeptin, but not insulin-like growth factor binding protein-1, predicted cardiovascular event at all occasions in unadjusted analyses. Copeptin remained as a predictor at discharge and after 3 months in the final multiple model (including: heart failure/age/creatinine clearance). CONCLUSION: The relationship between copeptin and insulin-like growth factor binding protein-1 during the initial phase of a myocardial infarction persisted in a less-stressful situation, and copeptin remained as a prognostic indicator at discharge and 3 months later.
