Fig. 2From: Elevated levels of interleukin-12/23p40 may serve as a potential indicator of dysfunctional heart rate variability in type 2 diabetesHeart rate variability changes with levels of inflammatory serum markers. Left: normal levels of IL-12 and ICAM-1 associated with normal heart rate variability. Right: increased levels of IL-12 and ICAM-1 resulting in decreased heart rate variability. IL-12 is known to associate with arterial stiffness in healthy [28]Back to article page
