Figure 1 (A) Concentrations of plasma oxidized low-density lipoprotein (Ox-LDL) in unstable angina (UA) and stable angina (SA) patients and in control subjects. *p < 0.001 vs. control subjects; p < 0.01 vs. SA patients. (B) Concentrations of circulating nuclear factor-kB (NF-kB) in UA and SA patients and in control subjects. The NF-kB was extracted from peripheral blood mononuclear cells derived from UA and SA patients and control subjects. *p < 0.001 vs. control subjects; p < 0.01 vs. SA patients.
