Moreover, patients in the MACCE group showed a significantly higher HR, Killip class, occurrence of arrhythmia, usage of IABP and ventilator, WBC, Glu, CRP, and Cr, but lower SBP, DBP, HBG, and LVEF than those in the non-MACCE group (P < 0.05) (Fig. 2, Tables 1–2). This evidence concerns the gene CRP and cardiac arrhythmia.
