[Predictive value of plasma interleukin 1, interleukin 6, interleukin 8 and C-reactive protein (CRP) in patients with myocardial infarction].
Long-term risk of mortality in patients with myocardial infarction is thought to be linked with plasma concentrations of proinflammatory cytokines and CRP (markers of inflammation). The aim of our study was to analyze plasma levels of interleukin (IL) 1, interleukin 6, interleukin 8 and C-reactive protein (CRP) in patients with myocardial infarction. One hundred and seven (107) patients with myocardial infarction hospitalized at the Cardiac Care Unit of St. Elizabeth's Sisters' Hospital in Warsaw and a control group of 10 subjects were enrolled in our study. The samples of peripheral venous blood were withdrawn from the patients on 2nd and 7th of infarction and plasma levels of IL-1, IL-6, IL-8 and CRP were determined. The patients were followed-up for a year. The analysis of survivals and deaths caused by acute coronary syndrome allowed to determine the predictive value of IL-1, IL-6, IL-8 and CRP in myocardial infarction. Twenty-two (22) of the total 107 patients died of acute coronary syndrome during one-year follow-up. Plasma IL-6 and CRP levels were higher in non-survivors as compared to the levels of IL-6 and CRP in living subjects, whereas plasma levels of IL-1 and IL-8 were comparable in both groups. IL-6 and CRP proved to be of predictive value in patients with myocardial infarction during one-year follow-up. It has also been found that plasma IL-6 level correlates with plasma CRP concentration and that there is a positive correlation between the former and CK-MB levels. IL-6 and CRP levels were higher in patients with Q wave infarction in comparison with non-Q wave infarction. Plasma levels of IL-1 and IL-8 have not been found to be good predictors of death during 12-month follow-up.
