The concentrations of markers were higher on the first day after MI with a maximum decrease on the third day. The levels of both markers in venous plasma correlated with those in arterial blood, allowing their routine determination in venous plasma on the first day after MI. IL-1β levels correlated directly with the wall motion index and inversely with left ventricular ejection fraction and stroke volume, which characterize the potential contribution to adverse myocardial remodeling. There were two multidirectional trends in changes in NLRP3 and IL-1β levels during hospitalization. Initially higher levels with a gradual decrease by day 7 were associated with a longer duration of myocardial ischemia and higher plasma troponin I levels. Further evaluation of the long-term outcomes of MI will allow identifying inflammatory factors that input to the development of secondary major adverse cardiac events and will provide a new step in the understanding of inflammatory phenotyping.
