Background: The possible clinical utility of endocan, a novel inflammatory biomarker involved in the initiation and progression of atherosclerosis, is largely unknown. We aimed to evaluate its diagnostic and prognostic performance in chest pain patients presenting to the emergency department (ED). Methods: We prospectively enrolled patients presenting with suspected myocardial infarction (MI) to the ED in an international multicenter study. Endocan, high-sensitivity C-reactive protein (hs-CRP), and high-sensitivity cardiac troponin T (hs-cTnT) were measured in blood samples obtained at presentation. Final diagnoses were centrally adjudicated by two independent cardiologists applying the 4th universal definition of MI and current guidelines. Non-ST-elevation MI (NSTEMI) was the diagnostic endpoint and 5-year cardiovascular death was the primary prognostic endpoint. Results: Among 4728 patients, 843 (17.8 %) had NSTEMI. The diagnostic discrimination of endocan for NSTEMI was low (area under the curve (AUC) 0.585 [95 % CI: 0.563–0.607]. Its combination with hs-cTnT (0.939 [95 % CI: 0.931–0.947]) did not improve the discriminative performance of hs-cTnT alone (0.937 [95 % CI: 0.930–0.950]). Long-term prognostic accuracy of endocan was higher versus hs-CRP, but lower versus hs-cTnT (AUC 0.730 [0.710–0.760] vs 0.650 [0.620–0.680] vs 0.810 [0.790–0.830], respectively). Endocan was associated with an increased 5-year risk for cardiovascular mortality. However, it did not provide relevant incremental prognostic value when added on top of a base model that included SCORE2 risk factors and hs-cTnT. Conclusion: Endocan has a low diagnostic accuracy for NSTEMI, and moderate long-term prognostic accuracy for cardiovascular death.
