TNF and coronary artery disorder: When PCI patients are diagnostically divided into STEMI, NSTEMI, CAD, and UA respectively, TNFα and IL8 levels are significantly correlated in NSTEMI (r2 = 0.82, p = 0.001) (Table 1, Fig. 1a) but moderately correlated in STEMI (r2 = 0.52, p = 0.014), and UA (r2 = 0.53, p = 0.001).
