Preoperative left ventricular ejection fraction was inversely correlated with IL-6 (p = 0.003, R2 = 0.202), CRP (p = 0.005, R2 = 0.171), and leucocytes (p = 0.005, R2 = 0.170), whereas patients with IDDM showed significantly higher level of IL-6 (p = 0.036) as well as patients with AHT (p = 0.044) (Figure 6). Here, CRP is linked to type 1 diabetes mellitus.
