Associations between macrophage inhibitor factor, anxiety and depression in patients with ST-segment elevation myocardial infarction

The aim – to investigate associations between macrophage inhibitory factor (MIF) and anxiety, depression and stress in patients with ST-segment elevation myocardial infarction (STEMI). Materials and methods. 73 patients with STEMI with TIMI-III aged 58.37±10.34 were enrolled in the study. Revascularization tactics distribution was the following: 43 (58.9 %) patients underwent primary percutaneous coronary intervention using bare-metal coronary stent, 30 (41.1 %) – pre-hospital thrombolysis with subsequent percutaneous coronary intervention within12 hours. Echocardiography was done during the period of hospitalization. Serum MIF was studied using the enzyme linked immunoassay method. Anxiety, depression and stress were determined with DASS-21 questionnaire. Results and discussion. When comparing the median values of the MIF level in STEMI patients, a statistically significant increase in the MIF concentration relative to control group (2582.80 [1308.40–4122.20] and 573.75 [397.80–1016.75] ng/ml, p<0.001). It evidences the activation of the formation of MIF after the index event. Positive correlation was determined between the level of MIF, the level of troponin I (r=0.33; р=0.045) and blood leukocytes (r=0.36; р=0.039) that confirms its involvement into inflammation and necrosis processes. The univariant and multivariate analysis revealed the effect of the degree of depression and anxiety growth on the DASS-21 questionnaire (p=0.0138 and p=0.0050, respectively) on the increasing of the MIF. Conclusions. The data obtained confirm the relationship between the MIF and anxiety and depression prior the onset of myocardial infarction, indicating their influence on the processes of inflammation.
