Predictors of coronary adverse events in patients with acute coronary syndrome with ST segment elevation treated with percutaneous coronary interventions with stenting

OBJECTIVE: The aim of this 12 months observational study was to investigate risk factors of major adverse coronary events, such as death or Q wave myocardial infarction due to stent thrombosis or in stent restenosis. MATERIAL AND METHODS: One hundred fifty four patients with ST segment elevation acute coronary syndrome were treated with percutaneous coronary intervention (PCI) and with implantation of metal stent. TIMI and CADILLAC scores were used for evaluation of initial risk. Blood levels of cytokines and sP selectin were measured on day 1 before PCI and on day 10 of hospitalization. RESULTS: We proved that CADILLAC score was applicable for evaluation of prognosis in patients with acute coronary syndrome and ST segment elevation treated with coronary stenting. High levels of tumor necrosis factor during first 24 hours of acute coronary syndrome and interleikin 8 on day 10 after PCI were found to be risk factors of major adverse coronary events during subsequent 12 months. High sP selectin level on day 10 predicted stent thrombosis during long term follow up.
