Biomarkers have taken one of the first places as diagnostic and prognostic tools in ST-segment elevation myocardial infarction (STEMI) and are consequently widely used as predictors of short-term and long-term prognosis. One of the promising biomarkers for early cardiovascular outcomes prediction is the pro-inflammatory cytokine macrophage migration inhibitory factor (MIF).

The aim of the study was to elucidate a plausible predictive value of the MIF levels for one-year clinical outcomes in STEMI patients who underwent primary percutaneous coronary intervention (PCI).

Materials and methods. 134 STEMI patients were enrolled in the study after receiving voluntary informed consent. All patients underwent conventional investigations, and additionally, the MIF levels were determined at baseline, directly before and after PCI. During 1-year follow-up, 37 % of patients reached the endpoint, which was composite and included all-cause mortality, non-fatal myocardial infarction, non-fatal stroke, hospitalization for unstable angina, heart failure decompensation, and urgent revascularization.

Results. We have found that pre-PCI MIF levels > 3934 pg/mL (AUC=0.7; 95 % CI 0.578 to 0.753; Youden index=0.31; p=0.008) might be an independent predictor of composite endpoints with sensitivity 54 % and specificity 82 %. A positive correlation between MIF and inflammatory biomarkers was revealed (WBC count r=0.33, p=0.0001; CRP r=0.19, p=0.032). Adverse outcomes associated with higher pre- and post-PCI MIF levels (OR 1.0, 95 % CI 1.0001–1.0008; p=0.013 and OR 1.0, 95 % CI 1.0001–1.0009; p=0.019) and CRP that determined during the first week after the event (OR 1.0, 95 % CI 1.005–1.2, p=0.03). Kaplan-Meier analysis has shown a substantially lower long-term survival rate in patients with a MIF level > 3493 pg/ml compared to a MIF level ≤ 3493 pg/ml (Log rank=0.00025).

Conclusions. The MIF levels exceeding 3934 ng/ml were associated with a higher risk of one-year adverse clinical outcomes in STEMI patients who underwent primary PCI.
