Values are shown as the median (the 5th; 95th percentiles).
* P value based on the Kruskal-Wallis test.
aLaboratory parameters were analyzed 24 h after the onset of chest pain.
PTX3: pentraxin-3; BNP: B-type natriuretic peptide; NOx: nitrite/nitrate; TNF-α: tumor necrosis factor alpha; MDA: malondialdehyde; 8-OHdG: 8-hydroxy-2′-deoxyguanosine; SOD: superoxide dismutase; FRAP: ferric-reducing ability of plasma.
