Abstract
Introduction: Reduced serum levels of glycosylated apolipoprotein J (ApoJ-Glyc) have been proposed as a marker for the early detection of myocardial ischemia with a potential prognostic value.Objective: The EDICA clinical trial assessed the performance of ApoJ-Glyc as a biomarker for the early detection of myocardial ischemia in patients attending the A&E department with chest pain suggestive of acute coronary syndrome (ACS) and investigated -as a secondary pilot objective- its prognostic value.Methods: EDICA -a multi-centre, international, diagnostic study (NCT04119882) assessed 404 patients. Based on clinical variables and diagnostic tests, 291 patients were considered to have had a “non-ischemic” event and 113 an “ischemic” event. Blood samples were obtained for the assessment of high-sensitivity troponin and ApoJ-Glyc at admission and at 1h and 3h thereafter. GRACE Risk Score was calculated in all ischemic patients. Patients were followed up for 6 months after presentation and the occurrence of MACE (cardiac death, recovered cardiac arrest, re-infarction, cardiac failure, new admission for ACS after discharge, or unplanned revascularization for cardiac ischemia after discharge) was recorded. ApoJ-Glyc serum levels were analyzed with a novel ELISA targeting a specific glycosylated variant of ApoJ (ApoJ-GlycA2).Results: Among the patients in the ischemic group, 8.8% had MACE at 6-months and these showed a 26% mean reduction in ApoJ-GlycA2 levels 3h post-admission compared with levels at presentation. This reduction was not observed in patients without MACE. Patients in the highest GRACE Risk Score tertile (>118 points) showed a progressive decrease in ApoJ-GlycA2 levels after presentation compared with patients in the lower risk tertiles (mean decrease: 41% at 1h, P=0.01 and 35% at 3h, P=0.02 when compared with admission levels).Conclusions: A progressive decrease in ApoJ-Glyc levels after A&E admission appears to not only identify patients with ischemic events but also those at higher risk of suffering serious recurrent cardiovascular events at 6-months’ follow-up. Further studies in larger cohorts of patients are warranted to validate the potential role of ApoJ-Glyc in risk stratification in the context of cardiac ischemic events.
